silky white hairs, with a few black ones arise from the subventral warts. The lateral row (row iii) furnishes shorter bristly yellowish hairs; but on joints 2 and 13 gives a long pencil of black hairs. A few black hairs also overhang the head and extend from joint 13.

[June-Sept. 1894.
From the subdorsal warts on joints 2-4, 8-11 and 13 arise tufts of plumed white hairs appearing "rnouldy" on the ends, intermixed with bristly yellow hairs. On joints 5, 6, 7 and 12 the warts of rows i and ii bear a series of large square black tufts, mixed with white plumed hairs especially at the sides of the tufts, where also a few bristly yellow hairs occur. The tuft on joint 7 is much less black than the others. Dorsally on joints 10 and 11 a median whiti~h retractile tubercle with flattened top.
Last staye.-Head black, whitish above the mouth. Body pale whitish with a yellowish tinge, shaded, marked diffusely with black; a dorsal and a stigmata1 band indicated. Two long, black pencils of hairs on joints 2 and 13 as in the previous stage. Lateral hairs long, dirty whitish mixed with a few black ones. Dorsal tufts as before except that those on joints 5-8 are now large, squate, brown ones, mixed at the sides with white plumed hairs; the tuft on joint 12 still remaining black as previously and contrast- ing with the others.
Cocoon composed of hair and silk.

My
description agrees approximately with
Smith and Abbot's figure; but this figure can hardly be very accurate as remarked by Prof. Riley (Proc. ent. soc. Wash. i, 88.). The brief description of the larva of Paro;/gyia clintonii" by Mr. Coquillett (Can. ent. xii, 45) also agrees with my notes, except that the author remarks that the retractile tuber- cles are "reddish."

Seifert, this larva has eight stages, while Dr. Packard gives it but five.* Mr. Seifert's larvae did not hibernate, which is unusual for this latitude. I believe this species usu- ally hibernates in the fourth and fifth larval stages.
Larva stage III. (?)-Head black, shining, mouth parts paler, sutures depressed ; width 1.34 mm. Body nearly black, a little mottled with whitish at the sides. Subdorsiil warts on joint 2 large, bearing a few plumed black hairs. From warts i and ii on joints 5 and 12 arises a square black tuft of plumed hairs. The other warts bear pale, sordid, whiti~h hairs; but from warts i and ii on joints 6-8 *Neither of these authors have given any measure- ments of the width of head, which would have enabled me to compare the stages observed by me directly with their descriptions. They have given measurements of the length of the larva, data which seem to me very variable and unsatisfactory. Nevertheless, the meas- urements of Mr. Seifert foJlow a series in geometrical progression fairly well, and, to judge Dr. Packard's work by Mr. Seifert's, usingthe length of larva as means of comparison, I conclude that Dr. Packard has failed to observe stages iv, vi and vii, as recorded by Mr. Seifert. Below, I give, comparatively, a calcii- lated series and the lengths of larva as found by these gentlemen.
Calculated series, ratio 7-10: 3.1, 4.5, 6.4, 9.1, 13.0, 18.6, 26.6, 3s mm.
Mr. Seifert's measurements: 3.9, 5.1, 6.5, 9.0, 13, 19 2$,26-3S mm.
Dr. Packard's measurements : 2.5, 4-5, 7, -, 12-14, -, -9 35 mm-
It seems evident that Dr. Packard must have missed at least one stage; for it is not possible to make his measurements fit a calculated series. However, such . is the uncertainty ofthese measurements, that it can be done by supposing that the larvae have sometimes only six stages, and that Dr. Packard missed stage v; e- 8 . 3
Calculated series, ratio 6-10: 2.7, 4.5, 7.6, 13, 21, 35 mm.
Dr. Packard's figures: 2.5, 4.5, 7, 12-14, -, 35 mm.

they are gray, forming slight dorsal tufts. On joints 10 and 11 a medio-dorsal whitish retractile tubercles.
Stage ZV. (?)-Width of head 1.65 mm.
As before, but the hair pencils from joint 2 are more distinct and there is abundant gray hair from the dorsal warts of joints 3, 4, 6, 7 and 8. Some larvae hibernate in this stage. Stage V. (?)-Head black, labrum and
antennae whitish; width 2 mm. Dorsum
covered by feathery gray hairs; but the
whitish retractile tubercles are exposed. Black hair pencils on joint 2 and square tufts on joints 5 and 12 as before.
This is the hibernating stage.
Food -plants.-Oak (Quercus), Hickory
(Carya) and wild cherry (Prunzts serotina). Parorgyia achatina larva differs from that of P. leuco-phaea in lacking the pair of black hair pencils which are present in the latter on joint 13.
The synonymy given above for the two
species of Parorygia is the same as that given by Dr. Packard (5th rept. U. S. ent. comm. pp. 135-138) except that I regard oblipata as the form of achatina in which the longi- tudinal black bar is absent (see Seifert, Ent. Amer. iii, 96) and not as a synonym of
lenco$haea. Further, I regard P. cinna-
momea G. and R. and P. flagiata Walk. as distinct species. In confirmation of this view, I have found a single larva on the hop- hornbeam in Ulster Co., N. Y., June 8, 1887, which differed from both those described above.
It had two pair of black pencils and
four tufts mixed with very feathery white hairs besides eight smaller dorsal tufts and a series of small lateral pencils.
The retractile
tubercles were red.
Head black, body whit-
i\h, hair whitish gray. I was unable to
obtain a moth from the larva, and have not met with it since. It seems likely that it may have been Parorgyia cinnamomea.
LEBENA OVILLA Grote.
1,have observed two stages previous to the last one which has been described by Dr. Packard (American Naturalist, xviii, 726). In these stages the larva is largely green and rests on the back of a leaf; in the last stage it is gray and hides by day in crevices in the bark. Its colors are well adapted to the sur- roundings which its habits lead it to choose at different periods of its life.
Stage II. (?)-Head pale yellowish,
mouth darker; width 0.45 mm. Body light
green, the wart i on joint 7 blackish brown with a small brown dorsal patch and faint, broad, greenish white doi'eal band. Other warts pale; hairs mostly pale, a few stiff, dark ones.
Length of larva about 4 mm.
Stage III.-Much the same. Width of
head 0.60 mnl.
Stage IV. (?)-Width of head 0.85 mm.
Much as in the next stage, though still
largely green. Markings brownish, clouded ; dorsal line scarcely continuous.
Warts pale,
except wart i on joint 7 which is black. Stage VI. ? (Last stage).--Head slightly bilobed, about as wide as high, full, well rounded ; ground color white, shining,
marked with dense black mottling, forming a black patch over the vertex of each lobe, and largely covering the clypeus, leaving the sutures white ; width 1.5 mm. Body flat- tened, projecting subventrally, abdominal feet present on joints 8-10 and 13 only. Three rows of warts on every joint. row i subdorsal, central; ii superstigmatal, ante- rior; iii substigmatal on a projecting base and iv smaller, on joints 3-1 I subventrally. Hair fine, radiating, not abundant, but
thickest and longest from the wart& of row . . .
111. Color sordid white 'with a black doisal line and several irregular and confused, crinkled, blackish lines along the sides, giving a dark gray appearance. On joints 2-4, 7 a ~ d I 1-12 the dark color predominates dorsally, forming diffuse, clouded patches, through which the dorsal line is less dis- tinctly defined by white than elsewhere. Thoracic feet brownish. Warts all pale,
some of row i tinged with black. Hair black and white mixed.
Venter sordid white.

ENTOMOLOGICAL NOTES.
A recent number of the Proc. Boston soc. nat. hist. contains a critical study and revision of the New England species of Spharagemon by Mr. A. P. Morse. The article is based on a large amount of material for the most part personally collected in various parts of the territory considered and upon examina- tion of the type specimens whenever prac- ticable, and is illustrated with drawings of the principal structural characteristics pre- sented by several species of the genus.
Three species are recognized as occurring in New England; another from Staten Id.
will probably be found in Connecticut.
The latter is described as new (S. ocz~latitm) and has probably been confused with 5. col- Fig. I, 2,3, S. aequale scudded Fig. 4,5, S. sam- tile. Fig. 6, 7, S. bolli. Fig. 8, S. oczdatum. Fig. 9, S. collare. 2 diameters.
lare. Of the former, one (S. saxatile) is new, having been hitherto confused with
the remaining two (6'. aequale and bolli). S. balteatum is reduced to a synonym, and the New England form of aequale is further distinguished by a trinomial (scudderi) for reasons which our space withholds. The
cut, on a smaller scale, and its explanation are given herewith. '
We are glad to commend and call the
attention of entomologists to the author's practice of examining an abundance of
material and distributing examples as one likely to materially advance the science by reducing errors and synonyms to a mini-
mum.
The death is announced of Edward Norton
at the age of 70, at his home in Farmington, Conn. Mr. Norton was one of the first natu- ralists of this country to devote himselfto the exclusive study of a single family of Hymen- optera, choosing the Tenthredinidae. It is many years, however, since he took an active part in entomological pursuits.
It may not
be known to many that he is said to have been the first importer of Guernsey cattle to this country and that he established the first creamery in New England.
In an extended notice of the first volume of Kolbe's new Introduction to Entomology in a recent number of the Entomologische nach- richten, Verhoeff declares it to be for ento- mologists the most important literary work of the last decade.
Under the insufficient and over modest title "On certain grass-eating insects," Mr. E. P. Felt of Cornell University publishes a synop- sis of the species of Crambus found about Ithaca, N. Y., treating the subject both systematically and economically, with excep - tionally full accounts of the life histories of those little known moths and abundant and very varied illustrations. 26 species are included. It is an excellent exposition of the Cornell method.
Mr. C. H. Tyler Townsend has again
changed his address to Las Cruces. N. Mex.
