Nystalea attenuata, Walk. Cat. xv. p. 1743). 
Hab. Panama, Volcan de Chiriqui (Ridbe, in mus. Staudinger).— VENEZUELA 1. 
This species is very close to N. inchoans. Dr. Staudinger’s specimen is the only one 
I have seen from our country. |

The type of this insect is now in the British Museum. A specimen from Chiriqui 
in Dr. Staudinger’s collection agrees perfectly with it.

ECREGMA. 
Ecregma, Walker, Cat. xii. p. 966; Butler, Trans. Ent. Soc. Lond. 1879, p. 34. 
This genus was founded by Walker upon a single species from Venezuela, and a 
second, from the Amazons, has been subsequently added by Butler; both these are 
now known from our country. Hcregma is very closely allied to the genus Hemiceras.
