Coxae of the three pairs of legs yellow, as is also the tip of the ab- 

 domen. 



Length of body .32; Exp. wings 1.10 inches.

CRAMBIDIA nov. gen. 



Head much as in Lithosia, but the front converges more anteriorly. 

 and the scales are coarser and lon2;er. Antennae setose, otherwise 

 simple, but a little stouter than in Lithosia and the porrect palpi are 

 larger, extending a little farther out beyond the front 



.Body as in Lithosia. Primaries narrow oblong, one-third as broad 

 as long. Costa convex, apex sub-rectangular, outer edge very straight, 

 one-fourth as long as inner edge. Nervures remarkably equidistant. 

 Costal midway between the marginal and s. c. nervure, 1st. s. c. very 

 short, arising remote from the 2d, and terminating on the costal, which 

 last is very long. 2d terminating on costa, opposite the fork of the 

 3d, which last encloses a long narrow apical interspace ; 5th, indepen- 

 dent. But two m. neroules, the nervure subdividing much within the 

 middle of the wing. 



Secondaries broad triangular, reaching beyond the tip of the abdo- 

 men, of much the same form as in Lithosia, but two m. nervules aris- 

 ing in the middle of the wing. Legs stouter than in Lithosia, with 

 much larger spurs. Abdomen with a prominent tuft. 



Xot only of smaller size than Lithosia, but differing in the straight 

 outer edge and convex costa of primaries, and in the neuration, 

 throughout; since Crambidia has one-half shorter s. c. nervules, and the 

 oth is situated nearly in the middle of the wing ; and I can discover 

 but two m. nervules, while Lithosia has three. Also in Lithosia, the 

 median nervure subdivides on the inner third of the secondaries ; in 

 our genus at the middle of the wing. When at rest the wings are 

 folded flat upon the abdomen, mucli as in Lithosia. 



Crambidia pallida n. sp. 



Of a very uniform drab color, without any markings. Head and 

 thorax tinged a little darker, while the nervules are very slightly paler. 

 Secondaries very little paler than the front wings. 



Length of body .35; Exp. wings .85-.9U inch.
