in dealing with T. mtna, calls attention to the complicated structure of the brand in 

 the primaries in the male, and this is so remarkable that we think it of sufficient 

 importance to put the species possessing this character into a separate genus. 



The antennae are barely half the length of the costa, and have a short stout club, 

 terminating in a short slender crook. The palpi have their third joint short, stout, 

 conical, and erect. The neuration of the primaries is similar to that of Thymelicus. 

 The brand in the males is very complicated and consists of the following portions : 

 1st, an elongate or oval velvety-black patch, extending along the second and sometimes 

 the third median segments ; 2nd, a smaller, more rounded, similarly-coloured patch 

 nearer the base, immediately above the submedian nervure (not always distinct); 

 3rd, between these, and crossing the first median branch, a mass of large, raised, 

 longitudinally striated, greyish, iridescent scales ; 4th, outside this last a large field 

 of variable extent of modified scales. The middle and hind tibiae are spined, and the 

 latter are furnished with two pairs of spurs. 



The four species we refer to this genus are all American, three of them being 

 apparently confined to either the Antilles or the Bahamas. C. druryi is a common 

 Tropical-American form extending northwards into the Eastern United States. The 

 field of modified scales on the upperside of the primaries in the males of C. ravola is 

 enormously extended, reaching to the outer margin.

In the British Museum the name Hesperia druryi is applied to an Antillean insect 

 which we have elsewhere described as H. ravola, but we cannot accept this deter- 

 mination as correct. The diagnosis of Pamphila plwcion, Fabricius, is too vague for
