LEPIDOPTERA OF NEW YORK AND NEIGHBORING STATES 109 



9. SI8YROSEA Grote 



(Isa Packard) 



Male antennae broadly pectinate to apex; antennae of female simple. Palpi 

 in male obliquely truncate, reacning middle of front, in female smaller. Hind 

 tibiae with end spurs only. Moth quite stout. Fore wing with outer margin 

 decidedly oblique, bent at middle, and slightly concave above, R, given off from 

 radial stem at a sharp angle, beyond the origin of Rj. Surface of wing when per- 

 fect, showing wavy scaling in transverse striae, much as in the Megalopygidae. 



The larva is strongly flattened. Its subdorsal spines are irregularly reduced, 

 and the lateral spines are very long, even, and feathery, and are held appressed 

 to the surface on which the larva rests. 



Sisyrosea is a primitive genus, in some ways transitional to the Phobetrini. 



1. S. textula Herrich-Schaeffer. Fore wing shaded pale gray, brownish, and 

 light flesh color. 20 mm. (Limacodes inornata Grote and Robinson.) (H. -47:14.) 



Larva green; feeding on wild cherry and many other shrubs. 



Massachusetts to Pennsylvania. New York: General from Plattsburg south- 

 ward. Larva more often seen than moth. 



10. NAT AD A Walker 



(Sisyrosea, in part) 



Similar to the last genus; R 2 free, wings rounded, with marked apex; scaling 

 normal; tibiae with four spurs. Larva high, prismatic, with short, subequal 

 horns, and no caltrop spines. 



1. N. nasoni Grote. Clay color, somewhat dusted with fuscous; with two oblique 

 dark lines. 25 mm. 



Larva green with yellow lines, and red tubercles; on oak and other trees. 



The moth, though commoner in the southern States, seems rare. New York : 

 Ronkonkoma and Yaphank, Long Island. 



Tribe Cochlidiini 



(Smooth Eucleids) 



Larva without tubercles or spines after first stage, spiracle of first 

 abdominal segment normal, and its lateral tubercle present. Pupa with 

 maxilla not extending out to antenna. Moth with R 5 free, usually 

 arising about half way between R 3+4 and M x ; usually with all spurs 

 on hind tibia. 



11. PROLIMACODES Schaus 



(Limacodes; Eulimacodes Dyar, not Moschler) 



Stouter than the following genera; male antennae serrate; R and M! of hind 

 wing normally stalked (fig. 70). Larva with broad dorsal and subventral areas 

 meeting in a sharp ridge, but without lateral area; in first stage with 2-haired 

 warts.
