Dyar.] 162 [Nov. i, 
spiracle on joint 8, and narrows to a line on joint 11 posteriorly, being 
incised on its edges in the segmental sntures, shaded witli blackish 
brown around its borders, and containing a darker dorsal and oblique 
subdorsal line, beside brown dots representing the tubercles; the third, 
on joint 12 posteriorly and joint 13, elliptical, covering the anal plate, 
but largely replaced by whitish. All the patches are bordered by a con- 
tinuous yellow line. Tails brown, green below at base and twice annu- 
lated with yellowish green : length 6 ram. 
As the stage advances a purplish tint suffuses the dorsal patches, the 
second one becomes darker obscuring its markings, but three pale orange 
patches appear in it on each side, behind the former oblique subdorsal 
lines, distinct or confluent and becoming pinkish yellow. There is a 
narrow reddish edging inside the now obscure yellow border. 
Cocoon. — Made, as usual in the genus, of pieces of bark and wood spun 
together over the hollow in the wood from which they were bitten out by 
the larva. The cocoon is not so thick as that of Cerura multiscripta, and 
it can be indented by the flnger. It fits the pupa closely. 
Pupa. — Cylindrical, slightly flattened ventrally, the ends rounded ; no 
cremaster. Color shining blackish brown, the cases darker, almost 
black, wrinkled, and less shining than the abdomen. Length 14 mm. ; 
width 4.5 ram. 
Food plant. — Willow (Salix). Larvae from Yosemite, California. 
If the larvae here describe^ are not different from those of 
Cernra bicuspis Borkh. (which I cannot determine at present), 
then the name scolopendrina must be referred to the synonymy ; 
for all the characters of the European species are exhibited in a 
series of specimens before me which were collected in California, 
Oregon, and Colorado. I am satisfied that C. albicoma Strecker 
is only a varietal form, the transverse band of the fore wings 
tending to be narrower.

Efjg. — Slightly more than hemispherical, the base flat, smooth, white, 
not shining; diameter 1.1 mm. Under the microscope it appears covered 
with granulations of uniform size, except just at the micropyle where 
there is an area of smaller ones. The shell, after the larva has issued, 
looks like the end of a thimble, it being difficult to distinguish whether 
the granulations are convex or concave. Tlie larva hatches by eating a 
liole in tlie side. Laid singly on the upper side of the leaves of the food 
plant.
