342 DIPTERA. 
Mesembrina anomala, Jaennicke (Neue exot. Dipt. p. 69), from Cuba, seems to agree 
in many respects with the present insect, but, according to the figure (tab. 2. fig. 4), 
it has a much broader abdomen and a narrow front (¢). Moreover, in the description 
nothing is said about the peculiar facial groove, which certainly would not have been 
overlooked by the author.
