ALDER CATERPILLARS. 629 
Moth. — Forewings rather broad and short, apex acute, as is the angle in the middle 
•of the outer edge of the wing; the corresponding angle in the hind wings well 
marked. Body and wings ocherous-yellow. Forewings with a broad dark basal 
broken band, bent at a right angle behind the subcostal vein ; a similar outer or 
extra-discal band, interrupted on the first and second median interspaces, and bent 
at right angles on the last subcostal branch. A marginal 
band, strongly marked on the costa, and succeeded by 
a row uf about five dark spots, the fifth beings ituated 
near the internal angle. Hind wings covered by a sin- 
gle diffuse broad median line, curved or bent outward in 
the middle of the wing. The wings beneath more heavily 
banded than above, and more strigated than above. Ex- 
panse of wings, 32 mm (1.10 inches.) 
Pig. 207.— Antepione deponta- 
ham'de7 tUral 8ize_Bridg - It differs from the specimen figured in my 
monograph in having the inner and extra discal 
lines and marginal spots well marked, while the borders of both pairs 
of wings are without the usual broad, dark shading. 
13. Geometrid larva. 
Found on the alder at Brunswick, Me., July 23. This larva began to 
pupate August 6. 
Larva. — Head rounded, slightly bilobed, not quite so wide as prothoracic segment, 
surface marbled with brown. Body rather thick, without humps, but with rather 
s"harp prominent piliferous warts, with four dark warts arranged in a transversely 
oblong square on top of each abdominal segment, those on the thoracic segments 
arranged in a transverse line. Anal legs rather short and broad ; supra-anal plate 
rather small, subtriangular, at the end six piliferous warts; general color greenish 
purple. Length, 17 mm . 
14. Geometrid larva. 
This caterpillar was first observed frequently on the alder at Bruns- 
wick, Me., July 23. 
Larva. — Head small, no wider than the body, smooth, of the same color as the 
body ; the body slender, cylindrical, with no warts; pea-green, the color of the alder 
leaf; two narrow dorsal thread-like yellowish lines; two wider dorsal lin^s outside 
■of the median ones: two lateral yellow lines, the lower on the lateral ridge and some- 
what broken; the segments wrinkled; anal legs rather small. Length, 13 mm . 
15. Geometrid larva. 
(PI. iv, fig. 5.) 
This unusual form of caterpillar occurred on the alder through Au- 
gust 1 to 18 at Brunswick, Me. 
Larva. — Body broad and flattened, ringed with brick-red. Head broad and flat, 
as wide as the body ; amber-colored, speckled with brown, in a wide median band 
on the sides ; segments brick-red between the yellowish sutures with interrupted 
dark red lines, so that the surface of each segment is somewhat checkered. The 
piliferous warts are large and distinct, while the spiracles are black, those" on the 
prothoracic and eighth abdominal segment being larger than the others. Supra-anal 
plate and anal legs amber-yellow, spotted with brown ; anal legs short but very 
broad ; supra-anal plate rather large, surface shining with six marginal piliferous 
warts. Thoracic legs dark towards the claws ; the abdominal legs amber yellow.
