but distinct. Palpi concealed in the long wool of the front, slender, 

 and not reaching to the front. The thorax is thickly pilose, stout, but 

 no broader than the short and broad abdomen. 



Primaries a little shorter than the body, two-thirds as broad as long; 

 costa straight, very slightly concave, but rounded at the apex; outer 

 margin oblique, regularly convex ; internal angle rounded. In the 9 

 the wing is more produced towards the apex, the outer margin being 

 longer. Subcostal nervure goes straight to the apex, throwing off the 

 1st, 2nd and 3rd subcostal nervules at nearly equal distances upon the 

 costa. Median nervules much as in Orgyia. 



Secondaries do not reach to the tip of the abdomen ; suborbicular, be- 

 ing regularly rounded from the costa around to the internal margin, 

 though the apex is slightly produced. Median nervure curved where 

 it throws off its nervules. A nervule divides the discoidal area. Legs 

 slender, very pilose, with distinct pencils of hair on the lobes of the 

 tarsal joints. x\t rest the wings are folded at right angles over the 

 abdomen. 



This interesting genus approaches very closely the genus Eudea in 

 the next subfamily, and connects that group with the more typical ge- 

 nera Orgyia and Euproctis. Resembling Euclea in that the 4th sub- 

 costal is continuous with its nervure, while the 5th is far removed from 

 it, in the antennae, the head characters generally and its light color 

 we find reasons for its present location. When we observe the larva 

 we would easily mistake it for a hairy Limacodes larva, for like them 

 the head is retracted, the body is short, and the legs are so rudimentary 

 as to impart a gliding motion to the caterpillar when it moves. But 

 since it is not apodous, and is somewhat elongated, and densely pilose 

 with short pencils of hairs ; while the pupa is also elongated and pro- 

 tected in an oval cocoon composed of hairs and silk, whereas those of 

 the next subfamily are nearly spherical, we are led to consider it with 

 Dr. Harris as belonging to the present group.
