line on seginenfc 8 . Anal feet pale outwardly, not used, slender, gently divergent. Mature larva 
corresponds in structure of the humps to Sehiznra hadia, and like it is largely green, being more 
green than Janassa and with lower humps. The larva in Stage 1 is scarcely distinguishable 
from Schizura ipomoecv, (Dyar.)

“ From two to ten laid together on underside of leaf. Rather more than hemispherical, 
flat below. Smooth, slightly shining, whitish green. Diameter, 1.1 mm . 5 height, 0.7 mm. Under 
Zeiss aa objective (60 diameters) covered with small, slightly raised hexagonal reticulations, 
which become gradually smaller toward the micropyle, linally becoming minute and dattened. 
Micropylenot depressed. The reticulations are slightly elongate on the sides but become round 
below and x>ass to the underside, where they are somewhat irregular, forming a triradiate area 
of much elongated meshes, the center of which is not always at the center of the egg.

LARVAL HISTORY OF HETEROCAIVIPA PULVEREA (see p. 249). 
I received too late for description in the body of this work the eggs and freshly hatched larva 
' of this species, kindly sent by Miss Ida M. Eliot, from Nonquitt, Mass. It was received and 
described August 29. It feeds on the oak. 
usual hemispherical form, shell white; surfiice seen under a lens to be finely 
granulated; under a one-half inch objective surface reticulated with distinct, regular hexagonal 
areas, which become narrow and small toward the apex of the egg; the surface of each area is 
roughened. Diameter, about 1.3 mm. 
Larva^ Stage J. — Length, 4 mm. Head large, much wider than the body, well rounded; surface 
smooth, unarmed, honey-yellow. Body tapering to the end, pale greenish yellow; abdominal 
segments 1, 3, 6 , and 8 banded with pink-red; on the side of segment 1 a distinct, oblique, pink, 
lateral stripe extending forward and ending at the base of the third pair of thoracic legs; the 
third abdominal segment pink above and on the sides, while only the upper side of segments G 
and 8 are pink. There are nine pairs of dorsal horns. Those on the prothoracic segment forming 
a pair of very large antlers, with four large tines, two extending forward, one shorter laterally, 
and the fourth extending backward. The other eight pairs on the abdominal segments are much 
as in H. guttivitta in general shape and size, though difiering in relative size. Those of the pair 
on the second abdominal segment are slightly longer than those on the first. The fourth to 
seventh pairs of the same size and length; eighth pair slightly longer; ninth pair about a quarter 
shorter than the eighth pair; all are piliferous, and become black-brown. 
This larva is nearest to that of II, guttivitta in Stage I; it differs in the following respects: 
The lowest tine of the prothoracic antlers is a little more than twice as long as in guttivitta^ all the 
four tines being nearly equal in length. All the chitinous plates from which the abdominal horns 
arise are entire except that on the eighth segment, aiid they are honey-yellow in color. The 
abdominal horns are nearly as in guttivitta (Fig. 83, III, c, d), but the second abdominal pair are 
smaller than those in segment 1 and only very slightly smaller than those behind; those on the 
third abdominal segment are of the same size as the three following pairs; those on the eighth 
segment are of the same size as those on segment 1. The .suranal plate is rounded and greenish, 
not black. The tines of the iHothoracic antlers are spiuulose, especially the one projecting 
backward. The thoracic legs are blackish; the abdominal ones pale greenish yellowish. Miss 
Eliot writes me that when first hatched the spines are pinkish, but that they change color in a 
few hours to brown. 
Stage II. — Length, 6 mm. Now of the same shai)e as in H, obliqua (PI. XXX, figs. 2, 2a), the 
l>rothoracic dorsal spines of the same shape, ending in two unequal sharp spines. In my alcoholic 
specimens the markings are as in H, obliqua of the same stage, but the dorsal lines are reddish, 
not greenish. The head is now banded and spotted, there being two longitudinal reddish bands 
on each side of the clypeal region. From the prothoracic dorsal spines two parallel blackish lines 
extend to the hind edge of the prothoracic segment. The body is mottled with red on the sides. 
Stage III. — Length, 14-15 mm. Head with two parallel blackish lines. The prothoracic 
spines large but blunt, bearing a hair, with two lateral teeth. Body with a reddish dorsal band 
forked in front, extending anteriorly to the inside of each tubercle and behind on the third thoracic 
. segment, dividing to unite again on the second abdominal segment, and sending an oblique line
