272 FIFTH REPORT OP THE ENTOMOLOGICAL COMMISSION. 
43. Apatela grbea (Walker), 
The caterpillar has been reared by Mr. Elliot from the elm. 
Larva after third molt.— Pale apple green, the dorsal region elevated into a ridge 
ami marked with a broken brown dorsal line, broadest on segments 2, 3, 8, 9, and 10; 
the brown patch on 2 with oream-colored edges; head pale green in center, brownish 
on the Bides, with paler marblings. Segments 3, 4, 5, 6, 7, and 12 have small raised 
tubercles bearing spines, and on second segment bunches of long hairs. Lateral 
region wholly pale green with whitish irrorations. Spiracles cream color, edged 
with black. Thoracic and abdominal legs concoloi*ous. Length 15""" (.60 inch). 
Full-grown larva. — Head dull chestnut brown, with some darker markings; body 
wholly yellowish green with a slight brownish tint. On segments 7 and 8 is abroad 
brown triangular patch, the mark being continued, slightly reduced in size, to the 
anal segment. Each of the segments bears brownish tubercles, with short, spinous 
hairs ; those of No. 5 have six tubercles, those of 8 and 9 three each, and the rest 
only two; there is a faint subdorsal brownish line broken up into patches; the spira- 
cles are brown, with redder brown patches above and below them. When at rest seg- 
ments 3, 4, 5, and 6 are very much elevated into a hump. All the tubercles bear 
short, sharp hairs, and there is also a series along the lower lateral region. Length, 
when at rest, 25 mm ; when feeding, 32 mm (1.28 inches). (Hy. Edwards & Elliott.) 
Moth. — Cinereous; abdomen and hind wings white. Fore wings rather short and 
broad, hardly oblique along the exterior border, with two irregular black discal 
ringlets, with a widely interrupted black stripe, and with two black bands, each of 
which forms a distinct Xi where it traverses the stripe ; interior band undulating, 
interrupted; exterior band zigzag; expanse of wings 14 to 16 lines. (Walker.) 
44. Apattla morula Grote & Robinson. 
Mr. R. Thaxter has found the eggs of this moth on the elm. They 
hatched July 12. The larva molts six times, the sixth time August 2. 
With the last molt there is a change of color and with this a change 
of habits, for the caterpillar instead of resting on the upper surface of 
the leaves, on which it spins a slight web, as in the preceding stages, 
betakes itself to the crevices of the bark, where it becomes almost invis- 
ible. 
The cocoon is spun under loose bark or in the crevices, and can often 
be found on the trunks of old elms, though the moth is somewhat rare. 
The present brood began to spin August 9, producing a single imago 
in confinement September 7 ; the moth usually appears in June and 
July. A larva also occurred on the linden September 15. u In their 
early stages the larvae of A. morula, furcifera, radcliffii, and clarescens 
can hardly be distinguished at a glance, and all except the last species 
produce striking changes of color after the last molt." (Papilio, iii, 13.) 
Eggs. — Very small, much flattened, whitish. 
Young larva. — Dirty greenish white, without marks; a few white hairs, a subdor- 
sal row black, head tinged with brown. 
After first molt. —July 15. Light green ; legs and setiferous tubercles white ; a 
subdorsal white band ; a few anterior and posterior hairs very long. Head light green 
with a lew longitudinal dark streaks. Length, 2.5" 1,n . 
After second molt. — July 19. Brighter green. Subdorsal band more distinct, inter- 
rupted on segments 1 and 10. A trausverse median dorsal red baud on segments 4, 
7, 11. Form more tapering abruptly anteriorly and gradually posteriorly from seg- 
ments3and4. Length, 6 mm .
