570 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 
departure from the usual structure and habits of a numerous family of 
moths, the end of the pupa being specially adapted for a residence iu a 
cocoon to prevent its being shaken out of its exposed pupal abode. 
Like all tree-feeding Noetnicto, the caterpillar is well protected from 
observation by its style of coloration, in the present case the pale 
green assimilating it to the leaves among which it feeds. 
•J."). CuttK-ula porta Guen. 
The caterpillar has been reared from the willow by Mr. A. \Y. P. 
Cramer and described in Papilro (iii, p. U4) by Mr. Henry Edwards. 
Mr. Hulst states that it feeds on the poplar, but on whose, authority 
is not stated. Mr. Thaxter, however, has bred it from the willow. 
Larva. — Dull fawn color. Head, as iu all the genus, flattened ou the top, with a 
deep frontal sinus. A black line surrounds the head, except at the Junction with 
the second segment. There is a pale brownish dorsal line, and a subdorsal oue, 
slightly waved, ou each segment, and inclosing a darker space. These lines are 
most apparent at the junction of the segments. A rather broad, brownish lateral 
line, slightly waved, incloses the spiracles, which are brown. Feet and legs cou- 
colorous with the body. At the extreme lateral edge is a row of short sharp ciliae. 
Length, 2.80 inch. (H. Edwards.) 
Moth. — Forewiug8 close smooth even bluish gray, with basal, apical, and sinus 
shadings; lines tine, but distinct; (VI of transverse posterior line produced, a white 
baud from within reniforin, extending obliquely outward, including the subreni- 
form, not reaching the inner margin. Hind wings rather dull red, median band 
even, curved, not reaching the inner margiu. Expands 80 to 85 mm . Eastern United 
States. 
Var. perplexa is slightly more shaded with blue and lighter. 
Var. petulans Hulst has yellow hind wings, with just a shading of reddish along 
the anal margin. (Hulst.) 
26. Catocala concumbens Walker. 
This has beeu bred by Mr. Saunders from the willow ; Hulst adds 
the poplar as also forming its food-plant. 
Larva. — Head flat, dark grayish intermixed with red. Upper surface dirty brown 
with a lightish chain-like dorsal stripe and a very small fleshy protuberance on each 
side of this stripe on each segment. On the ninth segment is a small protuberance 
of a brownish color and on the eleventh a mark resembling an oblique incision. A 
thick lateral fringe of short hair close to the under surface : the latter pinkish with 
a central row of round black spots which are larger about the middle of the body 
and much smaller towards the extremities. (Saunders.) Leugth, 2 to 2.50 inches. 
Moth. — Forewings pale violaceous brown, mixed with gray, lightest towards the 
costa; lines fine, but distinct ; reniforin vague, whitish, pale browu within. Hind 
wings bright pink; median baud very broad, rapidly narrowing towards the anal 
margin, which it does not reach ; the submarginal pink space even through its whole 
length. Expands ?•"> to 85 lum . Northern States. C. diana has the abdomen partly 
piuk. C. hillii Grote has yellow hind wings in place of pink. (Hulst.) 
'27. Catocala babayaga Strecker. 
The caterpillar of this Arizoniau species, according to Mr. Doll, 
feeds on the willow. The moth is like C. junctura. except that the fore- 
wings are of a rich velvety reddish browu. The wings expand 100 nmi .
