LEPIDOPTERA OF NEW YORK AND NEIGHBORING STATES 107 



5. EUCLEA Hiibner 

 (Limacodes, in part) 



Antennae of male closely pectinate about two-fifths way out, then strongly 

 serrate for a short distance, but with simple apical half; antennae of female 

 nearly simple. Palpi moderate, curved, and a little rough. Wings broad, all veins 

 present. Fore wing (fig. 69) with outer and basal part of inner margin strongly 

 convex. R 6 strongly, and R 2 often shortly, stalked. 



Larva stout and prismatic, not much smaller in front, subdorsal and lateral 

 spines irregularly but about equally developed; small pointed clusters of detach- 

 able spines between the terminal horns, the so-called caltrop spines. 



The genus is not really distinct from Parasa, and P. indetermina is intermediate. 



1. E. delphinii Boisduval. Brown, tending to shade into purplish brown and 

 tawny, more or less marked with green, the boundary often edged with white. 

 2530 mm. (cippus, quercicola, tardigrade, etc.) 



The larva feeds on various trees and shrubs. The moth flies in June. 



Montreal, Quebec to Illinois and southward. New York: Plattsburg, Peru. 

 The typical form, with varieties interjecta Dyar and viridiclava Walker, is rather 

 common southward. Variety elliotii Pearson is recorded from Big Indian Valley, 

 Coney Island, and Glendale, Long Island, and variety pcenulata Clemens is reported 

 from New York State by Packard. 



The following varieties are recognized, one or two of which may prove, on 

 breeding, to be distinct species. 



Key to the varieties 



1. Dominantly brown, the cell brown. 



2. One large irregular green patch viridiclava Walker ( H 47 : 23 ) . 



2. Two green spots connected by a row of dots interjecta Dyar. 



2. Two green spots only. 



3. Lower spot, below base of cell, small and triangular; upper spot some- 

 times broken into separate dots delphinii (H 47:24). 



3. Lower spot large and forked, or running out below cell. 



querceti Herrich-Schaeffer. 

 1. Dominantly green, cell green. 



2. A large, brown, discal spot elliottii Pearsall. 



2. No discal spot pcenulata Clemens (H 47:5). 



6. PARASA Moore 



(Euclea, in part; Callochlora Packard) 



Similar to Euclea, R 2 less frequently stalked; thorax green in our species. 

 Larva without caltrop spines. 



1. P. indetermina Boisduval. Male antennae merely serrate at middle. Vertex 

 and thorax green, underside brown; fore wing green, with a brown patch at base, 

 and a brown, slightly irregular border, about one-fifth as broad as length of wing, 

 normally with a darker shade at middle of outer margin. 25 mm. (viridis Reakirt, 

 vernata Packard) (H 47:10 <$, 15 $ as chloris.) 



This species and chloris have been much confused and even interchanged, making 

 published records uncertain. The caterpillar is not humped in front, and has 

 strong spines on the second, fifth, and last segments of abdomen. The caterpillar
