rather slender. The middle tibiae are without spines ; the hind tibiae have two pairs 

 of spurs. The primaries of the male are without trace of a brand, but they have a 

 pencil of long hairs beneath the first median branch in this sex, these in repose being 

 partly hidden in a longitudinal fold of the wing. 



We refer C. ozota with some hesitation to this genus, females only of it having been 

 seen. Both this species and Z. minos have large white discal spots on each wing above, 

 and a transverse whitish band on the secondaries beneath.

Of this distinct species we have a very long series, both from Central and South 

 America. We notice some variation in the shape of the discal spots of the primaries : 

 in some specimens they are considerably larger and more angular than in others, but 

 this does not appear to be associated with locality. The transverse band on the upper- 

 side of the secondaries is broader in Brazilian examples, but we have intermediate 

 specimens between these extremes. For the genitalia of the male, see Tab. CII.

VETTIUS, gen. no v. 



"We separate from Carystus various Tropical-American forms which have a small 

 conspicuous double brand on the primaries in the male. Papilio phyllus, Cram., is 

 taken as the type of the present genus, which will also include Hesperia lafresnayi, Latr., 

 H. laurea, Hew., Cobalus triangularis, Hiibn., and Carystus jabesa, Butl. Two of the 

 species enter the southern part of Central America. 



The antennae are very long, about reaching the end of the cell, and have an elongate 

 club, terminating in a long crook. The palpi have the third joint short and bluntly 

 conical. The primaries are moderately elongate, blunt at the tip ; the cell is con- 

 siderably less than two-thirds the length of the costa ; the discocellulars are strongly 

 oblique, the upper one more than three times the length of the lower, the latter short 

 and not longer than the third median segment ; the lower radial is much depressed at 

 the base ; the first branch arises considerably before the middle of the median nervure,
