128 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 
The caterpillars of the following species of Lepidoptera are not known 
to be especially injurious, but occur more or less frequently on the 
leaves : 
171. Basilarchia astyanax (Fain. Limenitis Ursula Fabr.). 
In New England a caterpillar occurred on leaves of the scrub oak as 
early as June 1; by June 7 it pupated, the chrysalis suspended verti- 
cally by the tail, while the butterfly emerged June 18. Harris also 
observed a pupa July 8, the butterfly appearing July 20. It also feeds 
on the willow, wild cherry, Carpinus americana, and various shrubs. 
It ranges from the Atlantic coast to Kansas. 
Larva. — Larva found feeding on leaves of scrub oak, June 1 ; head tinged with pale 
purple, two white stripes down the center of the face, lip brownish; vertex bifid, 
tuberculated, tubercles pale green. Body elongated, cylindrical, a pair of tubercles 
on each segment, those on the second beiug much elongated, linear, with short, blunt 
spines; first and second segments pale reddish-yellow, tubercles dirty green; third 
segment whitish or reddish white, veined with pale green above, tubercles pale ; 
fourth segment green above, tinged with ocherous, especially at sides ; fifth segment 
pale olive green above, darker at sides; tubercles whitish, transverse elevated liue 
at sides whitish, as it is in all the following segments; sixth segment olive green, 
with two longitudinal white lines above ; seventh segment olive green at sides, red- 
dish white or clay colored behind, and on the top two white lines with a clay-colored 
patch between, a small blackish spot near the stigma; eighth segment clay colored, 
slightly green at sides behind ; ninth segment greenish at sides, with a small black 
spot, clay colored above, before with two white lines ; tenth and eleventh segments 
dark olive green, tubercles paler; twelfth segment dark green above, tubercles four, 
ocherous. Feet ocherous; prolegs greenish bordered with ocherous. Body beneath 
whitish varied with green. Length, 1.3 inches. (Lintner.) 
Pupa. — Like that of B. archippus in form and color. 
Butterfly. — Expanse of wings, 3 inches. Upper surface black, tinged with bluish or 
greenish, and a little with fulvous at the apex of the fore wings. Along the outer 
margin are two rows of blue or green spots, the outer in the form of crescents, the inner, 
lunules. Under side brownish-black, the outer border repeated, preceded by a row of 
black and a row of fulvous spots, some of the latter obsolete near the posterior angle. 
There are two fulvous spots in the cell of the fore wings, three near the base of the 
hind wings, and some on the costae of both wings near the base. (French.) 
172. Basilarchia archippus (Cram. Limenitis disijypus Godt.). 
According to Scudder, French, and others, this butterfly occasionally 
feeds on the oak, and the accompanying figure was drawn from a cater- 
pillar found on the oak. (See Poplar Insects.)
