170 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 
shaped spots on a straw yellow ground, and the reddish-orange mam- 
milla} giving rise to pale hairs will distinguish this singular larva. 
Larva. — Head very large, full, btlobed, the Lobe lull and rounded, much wider 
than the body, pale, marbled with lilac. Five pairs of abdominal feet. Body short 
and thick, somewhat flattened, tapering somewhat toward the tail; straw-yellowish, 
with a row of dark broad, diamond shaped, brown spots along the hack, the spots 
connected and centered with yellowish. Four setiferous dorsal reddish rounded warts 
arranged in a trapezoid, with another wart on the side above each stigma. Body 
beneath paler. Length, 'JO'" 1 ". 
Moth.— Of the general shape of A. hamamelis, but very different in color and with 
distinct sagittate marks. Gray with a bright tinge, shaded with testaceous. A 
blaok basal dash extends to the twice strongly angulated t. a. line, which is gemi- 
nate, the inner more distinct line composed of raised scales. Above the basal dash 
the humeral space is pale beyond the geminate basal half-line. Median space wide 
superiorly, owing to the superior wide projection of the distinct and regularly den- 
ticulated t. p. line Orbicular rather large, pale, and vagu e, with clouded center. 
Costal black marks evident. Median shade apparent by raised darker scales. Reni- 
form vague, bisaunulate, stained with deep testaceous. A very narrow black dis- 
tinct dash at internal angle, broken at the pale continued s. t. line. A third black 
dash, indicated within s. t. line, opposite the disk. Secondaries fuscous, with the 
distinct black discal spot and dentate line of the paler under surface reflected. Ex- 
panse of wings, 1.45 inch. (Grote.) 
230. Scopelosoma morrisoni Grote. 
Order Lepidoptera; family NocTUiDiE 
The larvae of five species of this genus have, according to Mr. R. 
Thaxter, the same form and habit ; are omnivorous, and live in a case 
between two leaves, or within the folds of a single leaf; when young 
making a silk-covered burrow between two ribs or eating out a cavity 
in a bud somewhat after the manner of a Torticid. When fully matured 
aud somewhat soiled, it is hardly possible to separate the species. 8, 
morrisoni and walkeri are the most difficult to separate, but the more 
even and richer color of the subdorsal and dorsal regions, together with 
the obliteration of the dorsal and subdorsal lines, aud the clear white 
lateral line, render the latter species sufficiently recognizable when 
fresh. The lateral lines are substigmatal, the stigmata black, the body 
sparsely covered with minute tubercles bearing short colorless hairs in 
all the species. Form cylindrical, tapering very slightly, head moder- 
ate. The eggs of the present species were laid ou oak twigs April 22. It 
molts five times. 
Egg. — Stone color changing to reddish ; flattened inferiorly, a central superior de- 
pression from which radiate beaded ridges. Transverse diameter about 6 ram . 
First laival stage. — When just hatched, color livid yellowish green with blackish 
superior and anterior blotches. Head large, jet black. Thoracic aud abdominal legs 
black. A frontal semi-circular black plate ou segment 1. After feeding and when 
nearly grown indications of a dorsal, subdorsal, aud lateral streak. Color light 
green. Length 2 to \\ nim . 
Second stage. — A dorsal, two subdorsal, aud a substigmatal whitish line, the two 
subdorsal ones less clearly marked, especially the inferior. Setiferous tubercles, 
which bear short colorless minute hairs, blackish, indistinctly ringed.
