 Brazil l 2 ; Trinidad. 



Dr. Staudinger has sent us three males of this species from Chiriqui, and we have 

 others from Santa Marta, Trinidad, and Brazil. It is not unlike Carystus claudianus, 

 but may at once be distinguished by the longer antennas and the white apex to the 

 primaries, as well as in other particulars described above. There is a good deal of 

 variation in the underside of our specimens. The single male from Honduras in the 

 British Museum has the spots on the disc of the secondaries very much reduced in size. 

 For the genitalia, see Tab. CIV. fig. 11. 



B. Hind tibiae with two pairs of spurs. 



LYCHNUCHOIDES, gen. nov. 



There are two Tropical- American species very like Lychnuchus, the type of which is 

 Hesperia celsus, Fabr. (== Lychnuchus olenus, Hiibn.) ; but they differ from it in having 

 a longer and wider cell in the primaries, the first and second median branches much 

 less widely separated at their points of origin, and the brand in the male otherwise 

 formed. One of these species, Hesperia saptine, G. & S., from Costa Rica, which we 

 take as the type of the present genus, has the anterior tibiae tufted in both sexes, but 

 in the other, Asticopterus ozias, Hew., from Brazil * (the female only of which is kuown 

 to us), this is not the case. 



The antennas are elongate, half the length of the costa, with a long club, terminating 

 in a long crook. The palpi are densely clothed with scales, the third joint very 

 short and almost concealed. The primaries are elongate, truncate at the tip, the costa 

 arched to the middle, thence straight to the apex ; the cell is very large, two-thirds 

 the length of the costa ; the discocellulars are very oblique, almost in a line with the 

 third median segment, the upper one twice the length of the lower, the latter compara- 

 tively long ; the lower radial is depressed at the base ; the first branch arises about the 

 middle of the median nervure, the second long before the lower angle of the cell ; 

 the third median segment is only a little shorter than the second. The secondaries are 

 lobed at the anal angle ; the lower discocellular is distinct. The body is stout, and 

 (like the femora) very hairy beneath. The anterior tibiae, in L. saptine, are thickly 

 tufted with hair, especially in the male. The middle tibiae are not spined, the hind 

 tibiae have two pairs of spurs. The primaries of the male have a >-shaped brand, the 

 upper arm extending along the whole length of the second median segment, and 



* Not Java, as stated by Hewitson,
