1498 THE BUTTERFLIES OF NEW ENGLAND. 



July, never seems to become very abundant. Mr. Lintner has even 

 taken one as late as July 28. In the south it appears as early as the 

 beginning of March and the second brood from early in June to early in 

 July, after 13 days spent in the chrysalis (Abbot). The second brood in 

 the north appears about the middle of July and remains fresh throughout 

 this month ; occasionally fresh specimens may even be taken until the 

 middle of August, and the butterfly remains on the wing until the early 

 part of September. Lintner assures us that there are some color distinctions 

 between the two broods, individuals of the later brood being more subdued 



in tone. 



In the west the butterfly is found on the open prairie, with us it prefers 



wooded heights. 



Desiderata. The early stages of this insect are practically unknown ; 

 since it is double brooded even at the north, it would be comparitively 

 easy to rear in the localities where it is common if its food plant were found ; 

 the flight and postures of the butterfly are undescribed and no pai-asites are 

 known. It will be interesting to compare its life history with that of the 

 single brooded species.

Imago (15: 2). Head covered with slightly fulvous, mouse-brown hairs, mingled 

 with lighter brown scales, the latter visible only where they edge the eye or on partial 

 denudation of the top of the head ; tuft of radiating hairs at base of antennae scarcely 

 darker than those on summit and arranged in one vertical plane. Palpi furnished with 

 a profusion of dark brown, occasionally pale-tipped hairs, mingled above with an 

 abundance of gray scales, which are paler on the inner than the outer side of the pal- 

 pus; terminal joint densely clothed with recumbent mouse-brown, .slender scales. 

 "Antennae red at tip, annulated with a clearer white than in the other species, having
