Trista argentifrons, Walk. Cat. xxxi. p. 22. 
Hab. Mexico, Oaxaca (Sallé). 
The type of this species and the only specimen known to me is in the British 
Museum. 
SINCARA. 
Sincara, Walk. Cat. viii. p. 61 (1856). 
This genus was founded by Walker for the reception of an insect sent home by 
Mr. Bates from Para. It is allied to Melittia, from which it differs in its more robust 
form and short thick antenna, also in its being without the hair on the hind legs.

hyaline, the fringe brown: head, thorax, and abdomen blackish brown, the front of the thorax slightly 
yellow, the third segment of the abdomen yellow ; palpi and collar yellow; antennw black, yellowish at 
the base; legs brown. Expanse 12 inch.

I have only received a single specimen of this insect, in very poor condition, and do 
not feel certain about the yellow markings on the thorax and abdomen.

Sincara.
