NEW ACRIDIIDAE FROM THE SOUTHEASTERN STATES. BY ALBERT P. MORSE, WELLESLEV, MASS.
DURING a rapid trip through the southeastern states the past summer under the auspices of the Carnegie Institution of Washington, for the purpose of studying the Acridiidae of that region, the following new forms were obtained. These include two species of Eotettix, one long-winged and eleven short-winged species of Melan- opius, and a Spharagemon.
Sotettix putillus sp. nos.
.'
A diminutive species readily distinguished horn siguaius by its ;>he and nearly circular tegmina-- Facial costa widest between antennae, nearly equalling inter~pace between eye?, with parallel bides, abruptly narrowed below the median ocellun to two-thirds of its width above. Disk of pronoturn teeti form, distinctly convex in iongisection, the mid-carifia very pronounced, the lateral carinae faintly indicated on the prozone. obsolete on metazone.
Tcgmina broadly owate or subcircular, two-thirds or three-fourths as long as the pronoturn. Tip of male abdomen upturned, supra-and plate triangular, ncariy or quite as broad as long. pointed at apes, with sinuous sides. Furcula well developed, consisting of two broad httencd lobes as long as or longer than the last dorsal segment. Cerci subconic, shorter
than ropra-anal plate, two to three times as long as the width of base; acuminate, stout at baas, tapering to a slender tip.
General color pale yellowish green. dorsurn and tcgmina dull yellowish brown. Lateral
ttripcft on the sides of the prozone, more or less of the bases of the abdominal segments and genicufar lobes of the hind femora, apex of hind tibiae, tibia1 spines and tarsal claws, black. Hind tibiae colored like the body.
Length of body ; ,?, 10-12 ; 9, 16-17 ; hind femora : 8, 7.5-8 ; ?,9.5-tl; antenna: 8, 9, S-S.5; tegmina: S. 1.7 x 2 to 2 x 2.5 ; Q, 3 x 3.5 to 3.3 x 4 mw. Thrk males, one female, Waycross, Ware Co., Ga., Aug. 11 ; fourteen males, one
female, Denmark, Barnberg Co., S. C., Aug. 15. Intermediate in size and appearance between signdas and&csillus. Facial costa widest
opposite base of antennae, equalling interspace between eves, witla convex stiles convergent above and below, subparallel in lowest portion. Tegmina broadly oval with rounded apex. shorter than protiotum.
Abdomen of male less upturned at lip thnn wfusiltut; furcula well-developed, flattened or digitate ; supra-anal plate triangular, its breadth nearly or quite equalling its length, the apex rounded, acute. Cerci conical, slender, tapering evenly, about three times as long as thtir basal width. Color light yellowish green, brown above and on tepmina, with fuscous post-oculnr mtafipes from eves to tcgmina.
Hind tibiae red with black spines.

A ahort-winged species of the lame size nnd appearance an ishdiciis anti its two rela- tives hew described but belonging in a different series and easily distinguished by the sub- bifurcate cerci. Vertex blunt. Pronoturn broad with flattened disk, subungulate at junction with lateral lobes, nnd moderately convex hinder margin, the mid-carinit &tinct on the mctazone, absent from prozone. Prosternal spine short nnd variable. usually conical with acutely pointed tip but sometimes much broadened laterally with wide, bluntly rounded apex. Meaostenial interspace slightlv transverse in the female, narrower than the lateral lobes, quadrate or a little transverse in the male.

Agreeing with viridI/es in size. color, and markings but differing in the form of the *
cerci : in viridifes these organs taper somewhat regularly to the apex ; in this species more å´o less of their distal third is distinctly broadened dorsall$ and obliquely excised at the end, the apex being acutt and ventral ; the ventral tnargin may be convex, straight, or slightly tinuous, the dorsal m̤rgi is concave in the mesial portion, sometimes strongly so. The whole organ varies much in breadth in dikent specimens. Owing to its strong resemblance to ~iridipfs this species has been confused with it by various authors and a specimen was included with the types of that species. The original descriptions and drawings, however, accurately delimit viridijts from this and the suc- emding species.

In color and markings this species strongly resembles v-iridipef and dece/tu~ but possessed distinctive cfmracicrs in the markinga of the abdomen (as well a,s in the form of the cerci). In this species the subgenital piate is shining black, the preceding sternitc ~ppeenish white with a very broad triangular fuscous spot extending across its posterior margin below the upturned subgenital plate from which it is separated by a lenticular pale space along the suture.

Closely related to M. Madi'cm, agreeing with it in size, coloration, markings and form with the following exceptions.
Ccrci of male similar to those of islaadicm, stout at base, tapering equal!:, or nmre rapidly in basal portion, to a slender, flattened tip, once and a half or twice as long as width of base, symmetrical, the tip not bent upward nor grooved externally as usual in islandicus. Subgenital plate averaging shorter on the dorsal margin than in Xasdicus. Prosternal spine conic or cylindro-conic, the apex btunt, well-rounded, - in isiandicas subpyramidal,. acutely pointed, the sides flattened.

This species also is a near relative of islaniliriis Blatchl., differing chietiy in the form of the male cerci, which, while of the same general structure, are narrower at base and line the distal half bent slightly upward and drawn out into a slender, compressed, substyliiorin tip, the whole appendage being once-and-threequarters or twice as long as the width of base. The prosterna! spine is very variable, ranging from sitbcylindfical with bluntly rounded tip to a more usual conical form with rounded apes.

Intergrades may yet be d is- covered. The male from Pineoh is included with some doubt owing to differences in struc- tore and season.

A small species with very amiill ovate tegmina, attingent in male, a tittle separated in female. Disk of pronotum twice (male) or once-and-a-half (female) as long as wide. mid- carina percurrent, lateral carinae barely perceptible mesially. Prosternal spine prominent,
flattened cylindric, slightly curved backward, apex transversely excised, the angles rounded. Mesosternal interspace quadrate in female, slightly longitudinal in male. lletasternal inter- space longitudinal, twice as long as wide (female), narrower in male. Tegmina obovate, two-thirds as long a* pronotum. Hind femora stout, very obliquely bifasciate with fuscous. Hind tibiae glaucous, flarescent at bade and tip, with black-tipped spines. Male abdomen subclavate, the subgenital plnte and preceding segment tumescent, broader than deep, and greatly elongated, the former elongate scoop-shaped, bluntly rounded at apex. its sides a little convex, especially at base. Supra-anal plate broader than long,
somewhat trilobate at end by reason of deep, subapical iateral emarginations, the apex acutely pointed with straight sides, the basal three-fourths of each side smoothly convex, cawing abruptly into the subapical emarginations. Its upper surface bears strongly raised
edges and a prominent transverse ridge tnfdway of its length, crossing two-thirds of its width. To this ridge extend, lying upon Icm~itudinal ridges, the processes of the furcula; these are very broad at base, tapering equally to digitate, apically sinuate, tips which rest upon the ends of the transverse ridge, and enclose between them the shallow median sulcus, wide apically, narrow anteriorly. The base of the furcula and median portion of the segment bearing it are distinctly- depressed ; the median portion of the preceding segment is depressed to fit into this hollow, slightly elongated, widely and shallowly sulcate longitudi- nally, the suIcus transversely rugulose, with apical margin carinate opposite base of furcula. Ccrci short and slender, about two-thirds as long as supra-anal plate, nearly three times as long- as baaa! width, tapering evenly in hasal half to one-fourth the basal width, distally bent gently upward and in ward, the tip slightly expanded to about one-third the basal width, obliquely excised, the upper angle rounded, the ventral acute, the ventral margin convex or - -
