266 DIPTERA. 
fourth vein rectangular, without appendage, but with a faint fold in the surface of the wing ; apical 
cross-vein distinctly concave ; apical cell closed (or very narrowly opened) near the tip of the wing ; 
posterior cross-vein beyond the middle between the small eross-vein and the curvature of the fourth vein. 
The insect for which this genus is proposed resembles various Dexine in its slender 
form; but owing to the rounded shape of the anus in the male, and the plumosity of 
the arista, which does not reach the end, it is perhaps best placed in the group 
Sarcophagine. Prof. Brauer, who has seen the typical specimen, is of the same opinion 
(see Denkschr. k. Akad. Wissensch. lviii. pp. 366, 413). 
1. Paramintho modulata, sp. n., ¢. (Tab. VII. figg. 1; 1 @, head in profile.) 
Grey ; three thoracic stripes, some reflecting spots on the abdomen, and the legs black ; basal joints of the 
antenne rufous. 
Length 7:5 millim, 
Front blackish, as broad as the eyes, with a discal impression ; frontal bristles rather strong; on the vertex 
two longer bristles; face and sides of the front grey, the face with brownish reflections. Basal joints of 
the antenne pale rufous, the third joint black. Proboscis black ; palpi rufous, blackish towards the end. 
Thorax, scutellum, and abdomen grey ; the thorax with three black stripes and long bristles ; the abdomen 
with black reflecting spots, some of which form a dorsal stripe ; discal and marginal macrochete present 
on the second and following segments. Legs slender, shining black, with several long bristles; tarsi as 
long as the tibie ; foot-claws and pulvilli as long as the terminal tarsal joint; the pulvilli whitish. 
Tegule yellowish. Wings greyish-hyaline; small cross-vein on the middle of the discal cell; apical cell 
much narrowed towards the end, where it is almost closed; posterior cross-vein straight.

SARCOPHAGA. 
Sarcophaga, Meigen, Syst. Beschr. v. p. 14 (1826). 
This well-defined genus contains a very large number of species, which are spread 
over the whole world. More than 400 are described: of these, about 225 are from 
Europe (this number including the species belonging to Myophora, Rob.-Desv.), thirty- 
four from North America (including eight from Mexico), seventy-one from South 
America, twenty-six from Africa, twenty-eight from Asia (including New Guinea), 
nineteen from Australasia, and eight of which the origin is doubtful, but probably 
exotic. The descriptions are, unfortunately, for the greater part imperfect and do not 
give the most essential characters to distinguish the apparently homogeneous forms, 
and in many cases it is impossible to recognize the species intended by the authors. 
For this reason 1 am compelled to describe as new the whole of the Mexican species 
represented in the collections before me. 
Most of the characters for distinguishing the species are to be found in the male sex 
only ; and on this account I have not ventured to describe any new species on females 
alone, preferring to leave unnamed for the present several females.
