BELVOSIA.—ECHINOMYIA. 31 
measure 15 millim. (3) and 13 millim. (2); the smallest 11:5 millim. (¢) and 
9 millim.(?). One of the female specimens is labelled “ Tachina breviventris, Wiedem. 
(Brit. Mus.)?”; the description of that species, as given by Wiedemann, would indeed 
very nearly fit the present insect, if the palpi were not stated to be “black,” whilst in 
B. leucophrys they are rufous. 
The reasons on which I founded my opinion that the genus Blepharipeza ought not 
to be separated from Belvosia are mentioned by me in the ‘Tijdschrift voor Ento- 
mologie,’ xxvi. p. 26. 
There is still another Central-American species :— 
Belvosia trichopus, Bigot, Bull. Soc. Ent. Fr. 1887, p. exl (Blepharipeza).—

Consid. gén. sur la classe des Ins. p. 231 (1823). 
As this genus contains several common European species, I regard it as well known. 
Though the macrochete of the scutellum and abdomen are fully developed, they have 
not the appearance of thick and somewhat blunt spines, as in the preceding genera, 
but the more usual form of strong bristle-like hairs. Besides this, Echinomyia is 
distinguished from all other “ Tachinine” (except perhaps the genus Cyphocera) by the 
antenne, of which the terminal joint is almost always notably shorter than the second. 
The Central-American species known to me may be identified by the following 
characters :— 
1. Cheeks with a pair of bristles; palpi filiform. . . 2. 
Cheeks without bristles ; palpi more or less thickened 
towards theend. . . . . .. . 2... 8

apex. 2... 6 ee ee we eee we.) robusta, Wieder.

black thorax . . 2. . 1. 1. ww ee ee ee
