1826 BUTTERFLIES BEYOND NEW ENGLAND. 



Guatemala, Costa Rica and Venezuela ; it has occasionally been found in 

 the southern portion of the northern half of the United States, being 

 reported from New Jersey, Pennsylvania and Ohio. 



Although the early stages of this butterfly were studied and figured in 

 the last century by Abbot, and published by Boisduval and LeConte more 

 than half a century ago, we have not yet any proper account of the history 

 of the species. Abbot's notes, however, assure us that it winters in the 

 chrysalis and is more than single brooded. He reared specimens Septem- 

 ber 5 and February 20, the former after sixteen days in the chrysalis, the 

 latter from one that changed later than August. According to him, also, 

 the caterpillar feeds on Astragalus canadensis and A. glaber, as well as on 

 different oaks of which he specially mentions "blackjack oak," which is 

 perhaps Q. catesbyi. The only other published date of capture is one by 

 Aaron who took it June 11 at Atlantic City, New Jersey. It is, therefore, 

 very probably triple brooded in the south. 



ATLIDES HiJBNER.

Imago. Head not large, compact, the front slightly narrower below than above, 

 above as broad as the eye on a face view. Eyes as in Eupsyche. Antennae much less 

 than half as long as the fore wing, considerably longer than the abdomen, moderately 

 stout, increasing in size from the middle outward, separated at base by nearly the 

 width of the lower part of the front, composed of about thirty-five joints, the club 

 hardly separable from the stalk, increasing with the utmost regularity to the middle of 

 the outer half, beyond which there are about a dozen equal joints, less than twice as 

 stout as the stalk, and only a little broader than long, and then a couple of joints serve 

 to give the club a bluntly rounded tip ; the longest joints of the stalk are barely three 

 times as long as broad. Palpi very small indeed, the last joint, if appresscd to the head, 

 not reaching the base of the antennae by its own length, only moderately slender and 

 half as long as the middle joint. 



Fore wings shaped as in Thecla but with a relatively longer inner margin, the neura- 

 tion not affected by the exceedingly large discal stigma of the male, the cell considera- 

 bly less than half as long as the wing, truncate at tip where it is hardly more than 

 two-thirds its median width, the first superior subcostal nervule arising before the mid- 

 dle of the cell, the cell closed by feeble cross veins. Hind wings shaped much as in 

 Eupsyche, with a larger anal lobe and preapical excision. Subcostal forking sooner 

 than the median nervure. 



Thorax large and massive. Legs pretty stout and very heavily clothed, the fore 

 tarsi of male about a third shorter than the fore tibiae, scarcely more than half as 

 long as the hind tarsi or the hind tibiae, which are about equal ; fore tarsi of male 

 faintly jointed, densely clothed with spines beneath like the others, tlie apical three 

 or four very faintly arcuate, but not otherwise diftering from the ordinary spines ; 

 first joint of hind tarsi fully as long as the three succeeding joints together, the apical 

 pair of inferior spines of each joint slightly larger than the others. Claws exceed- 

 ingly small, fine and strongly curved ; paronychia forming a large, inferior, fringed 

 hood concealing the basal half of the hook. 



The early stages are known only through the illustrations of Boisduval and LeConte 

 which show nothing generically distinctive with certainty.
