lateral lobe of uncus having a greatly projected beaklike lobe on 

 posterior margin and with lower margin convex. Eighth tergite 

 (fig. 12a) similar to that of C. trebula and with anterior projection 

 narrow and extended, with incision of posterior margin shallow and 

 broad forming posterior lobes that are slightly acute laterally along 

 free margin. 



Female (pi. 2: figs. 15, 16). — Forewing dark brown except for two 

 rays of shining blue, one in base of wing below 2d A and the other 

 along base of cell. Hindwing mostly shining blue in color, very 

 much as in females of C. trebula with dark border becoming more 

 narrow toward costa instead of broader as is true in that species and 

 also as in C. trebula with this border broken into separate but nearly 

 confluent dark brown spots in interspaces M 3 , Cii], and Cu 2 . There 

 are a few red scales on anal lobe and there is a bluish-white marginal 

 line below vein M 3 extending to vein 2d A. Wings underneath 

 identical to those of the male. 



Length of fore wing 10.5-12 mm. 



Female genitalia as illustrated by figure 19 with ductus bursae 

 and bursa copulatrix relatively short, their combined lengths only 

 about three times the width of the superior genital plate; the latter 

 with its free edge divided into two lateral elements each with both 

 posterior and anterior spurlike processes that are reduced and about 

 equal in size and with the anterior spurlike process sharply pointed 

 and the posterior one blunt.
