14-. EUPSYCHE Scudder. 



Type: Tliecla 'isi-alhum Boisd.-Le C. 



This group is closely allied to Thecla, and especially to that portion of it 

 near which it is here placed, but it is readily distiuguishable from it. The 

 antennae are comparatively short, being less than half the length of the fore 

 wings in the male, with a very long club, not conspicuously and abruptly 

 thicker than the stalk. The discal stigma of the fore wings of the male is 

 roundish triangular, quite as broad as long, and is situated at the upper outer 

 corner of the cell, half within it and half beyond ; it does not (as in Thecla) 

 disturb the direction of the subcostal nervules, but the transverse basal por- 

 tion of the lowest inferior subcostal nervule, closing the upper half of the cell, 

 and directly upon which the stigma is situated, is rendered subobsolete there- 

 by. The shape of the wings is much as in Thecla, but they are somewhat 

 more elegant and angular, and are brilliantly colored with metallic tints; third 

 superior subcostal nervule of fore wings arising a short distance before the tip 

 of the cell; fore and middle tibiae of equal length, and slightly more than 

 three-fourths the length of the hind tibiae.

16. HYPAUROTIS Scudder. 



Type: Thecla Chrysalus Edw. 



This genus is closely allied to the European A urotis Dalm., but is peculiar 

 for the striking form of the hind wing, the hind border of which has a 

 square angular cut on the upper half, its angle at the tip of the middle sub- 

 costal nervule, and just before the middle median nervule an abrupt square 

 excision; the tail of the lower median nervule is long and thread-like. The 

 antennae are less than half as long as the fore wing, being equal in length to
