bands ; a ferrugiuous-brown patcli at the apex, and a longitudinal curved fascia from 

 middle of the discocellular widening to the outer margin below the apex : hindwing 

 with ferruo-inous-brown outer border.

Family LASIOCAMPID^. 



In the typical genera the wings are short and broad in the male, longer and 

 more ample in the female, and when at rest the hindwings project beyond the costal 

 margin of the forewings. Head and palpi projected prominently forward. Antennae 

 in male broadly bipectinated, less so in female, or broadly bipectinated at base only 

 and less to tip in male, and either moderately bipectinated, serrated, or simple in 

 female ; proboscis very short, invisible, or obsolete ; abdomen long and attenuated in 

 the male, very stout and generally with a lanuginose anal tuft in the female. 



Larva elongated, pilose ; some genera gregarious, others so only when young ; 

 either covered with silken hairs, which are generally arranged in tufts, some being 

 provided with a dense anterior and posterior tuft, or an elongated fascicle projecting 

 forward from each side of the head. Cocoon oval and firm, or fusiform and of slight 

 texture.

"Wings broad : forewing slightly arched along the costa, pointed at apex, sub- 

 falcate, exterior margin erect, convex hindward ; cell short, narrow ; first subcostal 

 emitted at one-fifth, and second and fifth from end of the cell, second trifid, third at 

 one-third and fourth at one-sixth from beyond base of second ; discocellular outwardly 

 oblique, convex, radial from above the middle ; lower median emitted at one-half and 

 middle median at one-sixth before end of the cell ; submedian with a slender lower 

 basal branch : hindwing broad ; apex almost pointed, exterior margin somewhat 

 angular in the middle ; anal angle slightly produced ; cell lengthened hindward ; two 

 subcostals from angles at end of the cell ; discocellular obliquely concave, radial from 

 above the middle ; lower median at one-half and middle median at one-fifth before 

 end of the cell; a submedian and internal vein; thorax stout, woolly; abdomen 

 short ; palpi porrect, broadly ovate, pilose ; antennje bipectinated in both sexes, 

 broadly in male ; legs pilose.
