94 ZYG^NIDiE AND BOMBYCID^ 



BOMBYCID^. 

 AECTIIN^. 

 Genus EUPEEPIA. Germar. 



Head small, not prominent. Front long and narrow, sides parallel; 

 finely scaled. Palpi stout, finely scaled, terminal joint pendent, slender, 

 projecting beyond the fi-ont. Eyes large. Antennae rather longer than 

 the thorax, approximate at the base, finely pectinated in the $ , sub- 

 simple in the ? . 



Prothorax hairy, vertical, nearly concealing the head fi-om above ; 

 thorax and patagia clothed with long hairs. Abdomen stout, smooth, 

 extending slightly beyond the hind wings. Legs stout, smooth; femora 

 hairy ; the middle pair with two, the hind pair with four short unequal 

 spurs. 



Wings ample. Anterior pair with the costa straight on the basal half, 

 thence gently rounded to the subquadrate apex ; outer margin full, 

 rounded ; anal angle distinct ; inner margin straight, convex at the 

 base. Median nervules arise a little beyond the middle, first and 

 second close together at their origin and curved downward ; fourth 

 four times as far from the third, as third from second. Costal ner\ure 

 long, reaching nearly to the apex. First and second subcostals thrown 

 off before the discal vein, long, parallel with the costal nervure ; third 

 subcostal arises at the discal vein, unites with the second to form a long 

 narrow cell, and is thence continued independently, throwing off the 

 fourth nervule to the outer margin, midway to the apex, and afterwards 

 bifurcating, both branches going to the costa. Fifth subcostal arises 

 on a short stalk at the discal vein, the latter being very slender and 

 strongly angulated inwardly. 



Secondaries have the costa slightly angulated, outer margin full and 

 rounded, anal angle rounded. Costal vein long, arising from the same 

 stock as the subcostal. 



Coloration bright and conspicuous ; primaries brown, with light 

 irregular bands similar to Arctia, secondaries spotted. The larva is 

 clothed with very long silky hair, thus differing strikingly from Arctia, 

 and showing a closer relationship with EpicalUa, although approaching 

 the former genus in the style of ornamentation. But one species is 

 found in North America.
