CHRYSOPIDB (NOTHOCHRYSIDB) COLLECTED
IN MEXICO BY DR. A. DAMPF (NEUR0PTERA)l
Holliston, Massachusetts
Early in 1947 Dr. Dampf sent me a large number of Chrysopidse, and later a smaller lot.
Much of the mate-
rial was collected in the 1920's, and almost all before 1938 ; so much of it had been in papers for many years it was fragile. Nearly a thousand specimens of Chryso- piella sabdosa were taken in the northern parts of Mex- ico ; it occurs in the dry parts of Colorado, New Mexico and Texas. About half of the rest was taken in or near Mexico City or at least in the Federal District. Of the others the most interesting were specimens from the States of Guerrero and Chiapas; many I had not seen. Dr. Dampf intended to send a third lot, and to collect in the summer of 1947, but sickness, and his unfortunate death induce me to publish on what I have now. As in other cases, I have been greatly helped by the notes pre- pared by Prof. R. C. Smith on the types of Navas that he examined in his sojourn in Europe.

Figures 18, 21
Green; face with two maroon bands; one from just be- low eyes and across clypeus, the other just below anten- nas, this one has an extension from the middle between the antennae to vertex where it divides and extends later- ally as a narrow streak just above antenna1 sockets to the eyes; the median lobe of vertex has two short parallel red streaks, and there is also a slender red line close to each eye; palpi partly black; antennas pale, the basal joint rather more red at tit).
Pronotum pale in middle
and each side with a broad maroon stripe ;the meso- and metanotum are pale in middle and broadly pale reddish on the lateral lobes; the abdomen has a narrow maroon stripe on each side. The pronotum is almost as long as broad behind, and about one-third narrowed in front. In the fore wing the subcosta is black to beyond the divisory cell, and many costals dark at one end; the first and second anal veins are also dark (maroon), and their branches are dark on base; elsewhere the venation (in- cluding gradates) is largely greenish; the costal area is not as broad as the radial area; the divisory cell ends beyond cross-vein, both sides convex; there are nine cubi- tals beyond end of divisory cell. In fore wing there are eight outer and seven inner gradates, in parallel rows, inner scarcely nearer to outer than to the radial sector, the first four of inner series disjoints the sectorals a little; in the hind wing there are seven gradates in each row, parallel, and the inner toward end nearer to radial sector than to outer row. The radial area is only a little broader than the costal area, the costals numerous, twenty-five before the stigma, beyond the last there are none in stigma1 area, but six in the subcostal area. The cubital area is about two thirds of the marginal area. In hind wing the costal cells are much longer than high. The hairs on all veins are rather short.

Ctzryso'pa mexicana Bks.
Figures 13, 17, 20, 37
The venation is largely green; there are twenty-four costals, dark at upper end; the fourth and fifth slightly sinuous ; eight inner gradates, nine outer, parallel, inner much nearer to outer than to radial sector; costal area about as broad as radial, cubital area about two-thirds of marginal area; in hind wing six inner and seven outer gradates, placed as in fore wing. In both wings several of the sectorals are bent by the inner gradates; in fore wing six forks beyond end of medius before the wing- tip. Palpi lined and last joint almost wholly black; the hairs on veins are quite long and reach half way across the slender costal cells.
From Presa San Jose, San Luis Potosi, 23 November. Chrysopa acolhua sp. nov.
Figure 5
Face with a reddish lunule under base of each antenna ; a narrow, reddish band below from under each eye and across base of clypeus, latter with a reddish spot each side; palpi mostly pale, but marked with dark; antennae pale, basal joint in front with an elongate reddish streak or triangle on the lower part; vertex with a red border each side close to eye, and a more narrow border to upper side of the antenna1 sockets, united to form an acute angle between antennae. Pronoturn much broader than long; each side is broadly reddish brown, leaving a much more narrow pale median area; thorax and abdomen without markings (but possibly with some when fresh). Wings long and moderately slender, venation pale, stigma scarcely darkened; costal cells on basal half of wing not numerous, and few, if any, twice as high as long, 20 costals before stigma, last four very short; divis-



================================================================================

ory cell ends a little beyond cross-vein, fully twice as long as broad, six cubitals beyond; in fore wing eight outer and five inner gradates, in hind wing seven outer and four inner, in both wings the inner row is much nearer to the outer than to the radial sector, at junctions the sectorals are slightly disjointed; costal area plainly not as broad as radial area ; cubital area as broad as mar- ginal area except toward base of wing.
Fore wing length 13-15 mm., width 3.84.2 mm. Type, from Pungarabato, Guerrero, Mexico (Jose Paner), 22 August.
Type: M.C.Z. no. 27997.
This species in many ways agrees with the descrip- tion of C. varicosa,Navas, but Navas says the inner gradates are arcuate, and the Smith Notes, "bowed up". Here the inner gradates parallel to the outer. Two speci- mens from El Mante, Tamaulipas have the venation al- most the same, but the cubital area is not so broad in pro- portion to the marginal area; the wings more slender, fore-wing 14 mm. long, width 4.6 mm.; the two lunules under antennae of the typical form here form a band, barely broken in middle; I presume they are a form of the same species.
Chrysopa tezcucana sp. nov.
Figures 7, 11, 28, 31
Pale greenish; face with a rather broad maroon band below bases of antennae, a zigzag black stripe under each eye, between are two pairs of rounded dark areas; a nar- row dark stripe between bases of antennas which forks on the vertex, but the forks soon become parallel; on each side of the pronotum is a red stripe, well separated from the margin, this stripe extends back on the lateral lobes of meso- and metanotum. Wings with green vena- tion, the bases of the first and second anal veins are black; the costals are black, twenty before the stigma, the cells higher than broad, the third or fourth costal is ' more or less sinuous; bases of radial sector and of dis- coidal cell black, most of the radial cross-veins black,



================================================================================

except ends, the cubitals and gradates also black. Six
cubitals beyond the divisory cell, latter about three times as long as broad; five or six gradates in each series, nearly parallel, and the inner nearer to radial. sector than tothe outer row; radial area much broader than costal; the cubital area about two-thirds of the marginal area. In hind wings five or six gradates in each row, about parallel, and inner nearer to radial sector than to the outer row'; the inner row disjoints the sectorals in both front and hind wings; the costal cells much longer than high.
Length fore-wing 14.8 mm., width 3.4 mm. Type from Lomas de Chapultepec, Mexico City, Mex- ico 8 August, also Cuernavaca, Mexico City, 26 April, the latter are a little smaller.
Type: M.C.Z. no. 27993.
Chrysopa trifurcata sp. nov.
Figures 1, 2, 32
Head pale, with pale red marks on face and vertex; face broad, a narrow band below antennae, making two curves, a broad red spot below each eye; in middle a transverse mark rounded above and with two projections below, enclosing a median pale spot. On vertex a mark starting between the antenna, giving off each side a streak to margin upper edge of antenna1 sockets, shortly behind the median streaks forks again, and each fork gives off a branch to the eye, the fork still curving out- ward and reaching the hind border, each end being fully twice as near to eyes as to each other.
The pronotum shows no definite markings, but the lateral lobes of mesonotum are partly suffused with red- dish and some faint reddish in some of the grooves. Ab- domen dark above (possibly reddish alive). Wings with pale veins ; in fore wings the gradates and many cross-veins pale brown, some almost margined. Costal area almost half as broad as radial area; 18 cos- tal~ before stigma, none sinuous, cells about as long as high; divisory cell is very broad, not twice as long as broad, the oblique base occupies about three-fourth of



================================================================================

the cross-vein.
From the third cubital cell there is but one vein behind, but it forks, equally in both wings, only one branch behind from the fourth cell; six cubitals be- yond end of divisory cell. In fore wings five gradates in each row and almost parallel, but both rows slope up- ward more than usual, the inner row much nearer to radial sector than to the outer row; the inner gradates strongly disjoint the sectorals ; the median vein ends fur- ther out on margin than usual, the end being as far out as the end of the stigma.
In hind wing there are four gradates in each row, the inner row much nearer to radial sector than to outer row, and also strongly disjointing the sectorals, the costal cells are mostly twice as long as high.
Length of fore wing 12.5 mm., width 4.1 mm. From Navojoa, Sonora, 24 March, 1927.
Type: M.C.Z. no. 27995.
The marks on vertex resemble those given by Navas for his Leucoc7wysa delicata; but trifwcata is not a Leu- cochrysa; the face has various red marks; Navas says head etc. "subtota f~sca.~' moreover he figures the pro- notum broader behind, in trifurcata the sides are parallel.

The'red of the anterior spots usually extends forward onto the vertex as a line near each eye. Costal area very
broad near base, equal to the radial area; 19 to 22 cos- tals, the third usually slightly sinuous; three to four inner gradates and about eight outer, the inner more or less divergent and generally nearer the radial sector, first of inner gradates bends the sectoral at juncture; divisory cell full twice as long as broad; cubital area

Chrysopa tortolana sp. nov.
Pace pale, no cheek mark, but a dark spot below each basal joint close to the socket, some irregular dark spots on basal joint and four to six joints beyond black (ex- cept second joint), beyond this some joints dark on one side; palpi pale; vertex and basal joints above faintly pink.
Pronotum with a narrow red line on each side of front part, and a shorter red line on posterior part, much more ' than its width from lateral margin, rest of thorax very pale yellow. Venation green ; gradates black, several of the longer radials dark near upper end, but not at end; some of the longer costals marked the same. Basal joint of antennae very short and small; prono- turn a little broader than long in middle, sides nearly parallel. Wings rather broad; costal and medial areas both very broad at widest part, but the costal plainly the broader ; eighteen costals, none sinuous ; marginal area much broader than cubital, in fact almost twice as broad beyond the third cubital cell; third cubital cell as long as and broader than the second; divisory cell about twice as long as broad ; six cubitals beyond ; medius ends far be- fore tip, full five forks before the tip. In fore-wing six inner and seven outer gradates, each gradate well separated from next; rows not parallel, the inner as near radial sector or nearer toward end than to the outer row; in hind wing four inner, six outer gra- dates, inner nearer to radial sector for most of length; in hind wings all veins green.
Length of fore-wing 14 mm., width 4 mm.
One from Verge], Chiapas, 4 June, at light. Type: M.C.Z. no. 27998.
This species resembles Ch. tetrasticta, but the anten- nae are black for a short distance and partly black for a greater distance, also the black on face, and the cross- veins not clouded separate it; the red marks on prono- turn are more slender than in tetrasticta.
