70 ZYG^NID^ AND BOMBYCIDiE 



B0MBYCID3;. 

 ARCHING. 

 Genus EPICALLIA. Hubner. 



Antennae moderate, subsimple in both sexes, (E. virginalis) or 

 slightly pectinate in $ (E. villica.) Palpi porrect, slightly pendent, 

 somewhat exceeding the front, finely scaled. Head clothed with short 

 hairs. Thorax and abdomen finely scaled, the latter as long as or 

 exceeding the hind wings. Wings ample. Primaries triangular to 

 subovate. Costa straight, slightly curved at the apex, outer margin 

 only slightly oblique. Secondaries large. Primaries spotted, neuration 

 similar to Euprepia. 



Larva clothed with very long silky hair similar to Euprepia. 



This genus is allied, by its antennae and fine scales on the body parts, 

 to Callimorpha on one hand, and by its neuration and preparatory 

 stages to Euprepia on the other. In its style of coloration it differs widely 

 from the last genus which shows a strong approach in this respect to 

 Arctia. But one species is found in the United States, and this, in 

 many of its characters, such as the simple antennae and finer scales of 

 the entire insect, shows a departure from the European type, which, as 

 pointed out by Packard, appears to be influenced by its association 

 with the woolly European genus, while the American form conforms 

 more to the finely scaled American genera Callimorpha, Euchaetes, Ec- 

 pantheria and Halisidota.
