Hab. Mexico, Orizaba (H. H. Smith and F. D. Godman), Cuernavaca in Morelos, 
Tepetlapa 3000 feet, Chilpancingo 4600 feet, and Amula 6000 feet, all in Guerrero, 
Atoyac and Medellin in Vera Cruz, Teapa in Tabasco, Mexico city (#. H. Smith). 
A considerable series of specimens of both sexes. 
3. Sarcophagula tenuis, sp.n., ¢ @. 
Cincreous ; thoracic stripes and reflections on the abdomen brownish ; frontal band reddish; antenne, palpi, 
and legs black. 
Length 2-2°5 millim. 
Head greyish-white; front in both sexes broader than the eyes; frontal band rufous, narrower than the 
lateral portions. Antenne black, rather short; third joint scarcely longer than the second. Proboscis 
and palpi black. Thorax, scutellum, and abdomen cinereous; on the thorax three brown stripes, 
which sometimes are indistinct. Abdomen ovate, in the g as broad as the thorax, in the 9 broader ; 
brown reflecting spots are more or less conspicuous on it; second segment with a pair of marginal 
macrochete, which, however, are absent in the 9; third and anal segment with several macrochete. 
Legs black, with some scattered bristles. Tegule whitish. Wings greyish-hyaline; neuration as in 
S. canuta, 
Hab. Mzxico, Chilpancingo in Guerrero, Cuernavaca in Morelos, Atoyac in Vera 
Cruz, Teapa in Tabasco (H. H. Smith). 
Two male and two female specimens. 
Two females, also with a fulvous frontal band, one from Atoyac (H. H. Smith), the 
other from Santiago Iscuintla (Schumann), are of a much larger size (4 millim.). I 
cannot, however, find any essential difference between them and the others. They may 
belong to Sarcophaga obsoleta, Wiedem. (Aussereur. Zweifl. Ins. ii. p. 367. no. 29), 
which, according to Giglio-Tos (Mem. R. Accad. Scienze Torino, ser. 2, xliv. p. 68), 
occurs also in Mexico.
