12 LEPIDOPTERA HETEEOCERA. 



costal terminating in only two veinlets ; discal veinlet nearly atro- 

 phied ; disco-cellular the same, united with the third median vein- 

 let ; aveolet rather large. Base of these wings in the male with a 

 strong bristle passing behind a strong corneous retinaculum, which 

 arises from the anterior side of the subcostal vein. Legs rather 

 long ; fore tibiae with a curved spine on the inside, covered by the 

 long scales of the tibiae ; fore tarsi twice the length of the tibiae, 

 basal joint longer than the rest combined, second and third equal, 

 the two combined equal to about two- thirds the length of the first; 

 fourth and (ifth very short, together about equal to the third. 

 Middle legs with the* tibia? about two-thirds as long as ihe tarsi, 

 with numerous minute spines along their sides, and two stont ones 

 at the apex ; joints of the tarsi having about the same relative pro- 

 portions as in the fore pair. Hind tibiae and tarsi nearly as in the 

 middle pair. Claws of all the tarsi stout, simple." — Doubleday. 

 Nearly allied to Hesperia, as is also the following genus.

" Fore wings black above, with a transverse macular sulphur- 

 coloured band beyond the middle, and a snbmarginal one, broadest 

 towards the apex, composed of greenish atoms. Hind wings with 

 a large oval sulphur-coloured spot in the areolet, separated only by 

 the median vein from a smaller one in the abdominal margin near 

 the base, and followed by a subtrigonate divided into three parts by 

 the median veinlets. Markings on the underside nearly as above, 

 with the addition of a greenish line along the costa of the fore 

 wings, bending landwards at its termination. Hind wings en- 

 circled by a marginal band of the same greenish colour. Body 

 black. Orbits of the eyes and a line across the vertex white. Palpi 

 bright crimson, except the last joint, which is black. Abdomen 

 whitish at the base and ou the edges of four of the segments ; last
