ATALOPEDES.— THYMELICUS. 479 



bordered above and below by a longitudinal streak of small velvety-black scales, and 

 inwards by long overlapping brownish scales; outside the brand there is a large 

 oval field of modified scales, which are opalescent in certain lights. 



The wings on the upperside are differently coloured in the two sexes. Watson, in 

 his Table, gives the hind tarsi as shorter than in Thymelicus, but this we fail to see. 

 The two species are American : one of them is very widely distributed and known 

 under various names ; the other is confined to Cuba and the Bahamas.

Our collection contains a long series of both sexes of this species from the Southern 

 United States and from within our limits. There is a certain amount of variation in 

 the coloration of both the upper and under sides of the wings, and some of the JNTorth- 

 American males are almost without spots beneath. 



Dr. Butler's type of Pamphila kedema, from an unknown locality 5 , is before us, and 

 it does not differ in the slightest degree from the female of A. campestris. For the 

 genitalia of the male, see Tab. XCIII. fig. 11.
