front tlinn lliat of B. gigantea ; its sides along tbe humeri are not sinuated, 

 and it extends more beyond tlie head. B. Atropos differs from it in the 

 colour of the hind wings, and the prothorax, which is much rounded on 

 each side in front, distinguishes it from B. Mexicana. The eyes are much 

 more Hpproximaie than those of B. Cubemis. The straight sides of the 

 prothorax distinguish it from B. Brasiliana, and il differs in colour, in the 

 structure of the prollioiax and in that of the fore wings from B. minor. 

 In the structure of the prothorax it much resembles/?. Sulzerii, hui the 

 sides are not obliquely truncated, neitlier are ihey rounded like those of 

 B. Irupezoidea and of B.femtyinea. The hind border of the prothorax is 

 lounded, not nearly straight like that of B. fralerna. The colour dis- 

 tinguishes it from B. Claraziana, B.fumigala and B. dubia.

 legs black, partly dark ferruginous. Head with the sockets of the aulennEe, 

 the two intermediate spots, and the space about the mouth testaceous.

 above; under side with the disk more or less ferruginous. Tarsi testaceous 

 beneath. Fore wings with a black stripe, which extends along the humeral 

 Tein to one-fourth of the length from the base, and is there widened and

 base, nearly straight from thence to the tip, which is much rounded ;

The much smaller size and the somewhat darker veins of the hind 

 wings distinguish it from B. gigantea. It diflers more widely in colour 

 from B. Alropns and from B. Mexicana, and from B. Cubensis and from 

 B. minor. From B. Brasiliana it differs in the prothorax, which has no 

 tendency to a trapezoidal form, and is by no means angular in the middle 

 ol the hind border. Tiie si<les ol the protliorax are not truncated like those 

 of B. SiiUerii and of B. (/uadrifera, and the less dilated prothorax dis- 

 tinguishes it from B. trapezoides and from B.ferruyinea. The colour of
