Four males and six females. This species, especially the female of it, resembles 
E. analis (Fabr.), but differs in having genal bristles and in the thin, filiform palpi. 
Tachina seminigra, Wiedem. (Aussereur. zweifl. Ins. ii. p. 296), included by Schiner 
inthe genus Echinomyia, must also be a nearly allied form ; but as Wiedemann piaced 
it among the species with the second and third antennal joints of equal length, and 
E. generosa has the third joint distinctly shorter, | do not think that they can be 
the same. 
Wiedemann’s specimen of Z. seminigra was from Brazil, and those of Schiner from 
Chili and Colombia.
