This species is very similar to A. schlaegeri in coloration but it 

 is generally smaller. The presence of an uncus with a broadened 

 bifid tip and a broad, apically flared aedeagus in the male genitalia, 

 and a reduced genital plate and small corpus bursae in the female 

 genitalia readily separate this species from A. schlaegeri. 



The name of this species has been in doubt for a number of years. 

 The type locality for Walker's C. algidella is Nova Scotia and for 

 ZeUer's C. leiwillana is Georgia. There is, according to Walsingham 

 (1889), some color variation between the southern and northern 

 limits of distribution and this variation is responsible for Walker's 

 description of C. algidella. Although the location of Zeller's type is 

 uncertain, a Zeller specimen from Texas labeled C. leucillana in the 

 British Museum is identical to Walker's type of C. algidella. Ob^dously 

 this problem cannot be resolved adequately until Zeller's type of 

 C. leucillana is studied and compared with that of Walker's C. algi- 

 della; however, since indirect evidence indicates that both names
