154 HETEROCERA. 
Mr. Champion captured a very large series of specimens of this species, which show 
a considerable amount of variation in the size of the yellow marking on the primaries, 
and also in the distinctness of the white lines on the underside of the secondaries. 
According to Mr. Champion, this insect is very abundant along the summit of the 
Cordillera in Guatemala. It flies by day, frequenting damp sandy spots by the road- 
side, where it congregates in large numbers. 
OBILA. 
Obila, Walker, Char. of undescribed Lep. Het. p. 61 (1869). 
Walker placed this genus in the Larentiide, without giving any indication as to its 
affinities. It is quite unknown to me.

Apparently a common species in Mexico, but becoming rarer southwards. The 
specimen received from Dr. Staudinger is labelled “ Camptogramma balteolata, Herr.- 
Schaff. ;”’ Iam unable to find that this name has ever been published.
