HETEROPACHA RILEYANA.
BY CAROLINE G. SOULE, BROOKLINE, MASS.
Eggs laid July I, 1891, at Columbus, Ohio. Eggs globular, opaque white mottled with dark green, a dot of green on top.
July 11, 1.30 P.M., they hatched.
Young larvae 1-8 inch long. Head very
large, round, horn-colored mottled with
brown. Body gray, striped longitudinally with dark brown on each side of the dorsurn. 11th segment black on top. Body covered
with short, gray hairs. Feet and props
gray. Anal props very slender and spread far apart. The body tapered from head to anal end. The larvae moved very fast, and were flat instead of cylindrical.
Three days later they had changed some-
what in color, the head being dull white barred with brown; the body dull white on dorsum with a black dorsal line, and a black dash on each side of this line. From each dash arose a small, dark wart with short spreading hairs. The sides were dark gray with a dull white line from 5th segment to anal props. The hairs were most abundant over the head and feet, and were grayish. Each segment had a few warts, with sparse short hairs.
July 16. first moult. Head darker, hairy, mottled with white, the dark and white lines extending back over the firbt segment, the body, as before, giving the effect of black and white stripes. The tapering from head to anus was very noticeable, as was the flat, leech-like shape. The hairs were long over the feet, shorter along the stigmata! line, and very short on the sides and dorsum.
July 19. Second moult. Length 1-2 inch.
Head dark barred with white hairs. Body
tan-colored on dorsum with two black dashes on each segment. Lateral and stigmatal
lines nearly black. A black patch on top of the 11th segment. Feet and props dark
gray. Hairs sparse and short except over feet and props, where they seemed to "fringe" the whole edge of the larva.
July 23. Third moult. Length one inch
or a trifle less. Head black with two short yellow lines on top, and a yellow spot near the mouth, hairy. Body brown on dorsum,
yellow between the segments, with black
dashes>. Two yellow dashes on 12th segment. No black patch on 11th segment. Lateral
and stigmata1 lines of black and pale brown. Feet and props dark, overhung by long gray hairs in tufts. Very short hairs on the dor- sum, and very sparse.
July 27th. Fourth moult, I 1-2 inches
long. Head as before. The body was
marked with brown, black, tan, and yellow or white, in a sort of "oil-cloth pattern" very difficult to describe, and varying with indi- viduals. The dorsal hairs were unnoticeable without a lens, but the stigmatal fringe Pswhe 6 l9J- 194 tprc. 1903). htlp:t/psyclir nilclub org/&'6-19J html

remained, and the general look of the larvae was like Tolype lands except in color.
The larvae moved very rapidly, and when
at rest lay closely adhering to the twig of honey-locust, so flat as to be inconspicuous. The cast skins seemed to be thicker and
more leathery than those of most Bombycid larvae. These larvae drank less than most that I have reared.
Cocoon. Aug. 5. The first one spun a thin parchment-like cocoon, 3-4 of an inch long,. oval, slender, of a red-brown
color mottled
with gray. It spun very slowly, taking over two days.
Pea. Aug. I I. The pupa was formed. It
was 3-4 of an inch long, slender, dark brown, and had a white chalky substance all over it, which fell off when the pupa was touched. PREPARATORY STAGES OF PHEOSIA DIMIDIATA H.S. BY HARRISON G. DYAR.

Egg. Hemispherical/the base flat, smooth, sublustrous, white.
Under the microscope it
appears closely covered with dense, very small, rounded granulations, which are of about uniform size, but fused into a small white spot at the micropyle. Diameter 1.1 mm. Laid singly, usually on the under side of the leaves of its food-plants.
The larva
hatches by eating a hole in the side of the egg, but leaves the rest of the shell intact. First stage. Head slightly bilobed, black and shiny ; labrum white ; a few hairs ; width .6 mm. Joint 12 is slightly enlarged dor- sally, otherwise the body is uniformly cylin- drical. There is no trace of the caudal horn so conspicuous in the last stage. Body pale white; cervical shield, anal plate and tho- racic feet black. From the minute elevated dots arise blackish hairs which are appar- ently not glandular but pointed at tip. A subventral broken blackish band which later changes to purple. Legs normal, the anal pair not elevated, all black outwardly. Near the end of the stage a purplish patch appears under the skin on joint 12 dorsally in the location of the piliferous dots of row I, indi- cating the origin of the caudal horn. The piliferous dots of row I are close together on joint 12, more normal on joint 11 and almost in line with those of row 2 on the anterior segments. Row 3 are large, lateral; rows 4 and 5 small; row 6 distinguishable only on the legless segments and row 7 normal, on the venter of the apodal joints. In the latter
