EASTERN UNITED STATES. 229 



The food-plant is Oroton capitatum, and probably also 

 Oroton monanthogynum, as the butterfly is to be found 

 where the first plant does not grow but the latter does. 



Western States from Illinois to Texas, Nebraska. 



SUBFAMILY SATYKIN^E. 



In this group the palpi are close, elevated, very hairy, 

 the discal cells always closed, and the veins of the fore 

 wings usually dilated at base. In Debis the eyes are 

 hairy, in Satyrus naked, while in Neonympha they vary, 

 some species being hairy and others naked. The butter- 

 flies in the Eastern United States vary from russet to 

 dark wood-brown or nearly black, and in most species 

 have eye-spots on the under side of the hind wings at 

 least. The larvse are cylindrical, tapering slightly from 

 the second segment, the head larger than this segment. 

 The body is more or less provided with small tubercles 

 supporting hairs. Grass constitutes the principal food- 

 plant. The chrysalides are more nearly cylindrical than 

 in the preceding subfamily. 



81. DEBIS PORTLANDIA, Fab. 



Expanse of wings from 1.75 to 2.25 inches. 



Upper surface wood-brown, rather light, the outer 

 third a little paler, the division marked by a darker 

 shade of the ground color, more pronounced on the fore 

 wings, the line dentate with two prominent teeth oppo- 

 site the discal cell, from which it bends inward before 

 a whitish somewhat oblong costal patch. In this paler 

 terminal space there is an anteapical whitish dot in line 

 with four or five round dull black spots annulate with
