﻿84 SEVENTH ANNUAL REPORT 



the moth is wingless. The color is light brown with darker wing-sheaths. 



Anisopteuyx roMETAUiA. Harris — Egg — Length, 0.025 inch ; average diameter 

 I the length ; flattened at top where it is somewhat larger than at base. Color of 

 crown purplish-gray, the surface slightly corrugated, with a centi-al dimple and a 

 brown circle just within the border; sides smooth and more silvery, and generally 

 somewhat compressed by pressure of adjacent eggs. Laid in exposed situations, in 

 patches or strips, attached in regular rows, and fastened to the bark in a slightly 

 slanting position so that one edge of the crown is a little above, the other a little below 

 the general level. 



Larva — Color pale brownish, marked with dark brown and yellow as follows : 

 The dorsum uniformly dark brown ; the sides with three pale narrow lines, more or 

 less irregular and mottled, but always well relieved, the two superior ones white, the 

 lower most yellowish ; the subdorsal space between the upper two of these lines, 

 pale ; the stigmatal between the lower two darker, especially in middle of the 

 joint around stigmata; the thoracic joints dark with the pale lines somewhat nar- 

 rower and running up to the head. On joint 11 these lines are constricted or entirely 

 broken, so as to leave a dark band across the middle of the joint. The head is dark 

 brown above and at sides, but paler in front. Cervical shield also dark with the yellow 

 lines running through it. Venter olivaceous, the legs more reddish, there being three 

 pairs of prolegs, the pair on joint 8 only half as long as those on 9, but with perfect 

 booklets ; the thoracic legs quite hirsute and terminating generally in two thorns. 

 Piliferous spots obsolete and with a very few scarcely distinguishable pale hairs, except 

 on anal shield and legs, where they are stouter. Anal shield and legs with brown pilif- 

 erous dots. The newly hatched larva is pale olive-green with a large pale yellowish 

 head and pale legs. The light lines of the mature larva are, at this early stage, faintly 

 indicated and the piliferous spots give forth short, flesh}', pale hairs. The third pair 

 of prolegs is distinctly visible, but is not used in locomotion. After the first molt the 

 head and thoracic legs become somewhat browner, and the olivaceous green more blu- 

 ish. After the second molt, the dark colors show much more distinctly. 



Described from numerous full grown specimens received from Mr. B. P. Mann, 

 others received from Dr. A. S. Packard, Jr., and a larger number of all ages reared by 

 myself from the egg. 



It varies somewhat in intensity of color, and in some the light and dark browns 

 are not so sharply separated, but the dorsum is generally uniform and the three lat- 

 eral yellow lines distinct. Up to the second or last molt, the general color is, with rare 

 exceptions, greenish ; but in the last stage, the dark-brown or black predominates, and 

 is sometimes so general that there is but the faintest trace of the superior yellow 

 lines. Occasional specimens, even when young, show in the subdorsal dark space, 

 one, and in the dorsal dark space, two, very fine and faint pale lines. Differs entirely 

 from vernata in lacking most of the characteristic spots in front of the head of that 

 .species, and the two pale transverse marks ; in having the dorsum darker instead of 

 lighter than the rest of the body ; in lacking the medio-dorsal pale lines and the char- 

 acteristic x-like marks ; in the broader, more conspicuous pale lateral lines, and in the 

 subdorsal space being darker than the stigmatal ; and lastly in the additional, though 

 atrophied, abdominal prolegs. It is a smoother larva. 



Chrysalis — Color light brown, with the wing-sheaths, a medio-dorsal shade, 

 sutures and stigmata darker. Length 0.30 — 0.35 inch ; stout, with the wing-sheaths and 

 their veins distinct in the female ; a dorsal, bifid, decurved tubercle upar the tip of 

 anal joint.
