The caterpillars of the following species of Lepidoptera are not known 

 to be especially injurious, but occur more or less frequently ou the 

 leaves : 



17L Basilarchia astyanax (FahT. Limenitis Ursula Fahr.). 



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, Garpinus americana, and various shrubs. 

 It ranges from the Atlantic coast to Kansas.

 purple, two white stripes down the center of the face, lip brownish; vertex bifid, 

 tuberciilated, tubercles pale green. Body elongated, cylindrical, a pair of tubercles 

 on each segment, those on the second being much elongated, linear, with short, blunt 

 spines; first and second segments pale reddish-yellow, tubercles dirty green; third 

 segment whitish or reddish white, veiued with pale green above, tubercles pale ; 

 fourth segment green above, tinged with ocherous, especially at sides ; fifth segment

Pupa. — Like that oi' B. archippus in form and color. 



Butterfly. — Expanse of wiugs, 3 inches. Upper surface black, tinged with bluish or 

 greenish, and a little with fulvous at the apex of the fore wiugs. 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 disippus 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.)
