extending a little beyond the upper. Small cross-vein under the end of the first vein ; 
anal vein elongate, but not reaching the border of the wing. 
A single species from Northern Mexico may be considered as belonging to the genus 
Pogonomyia. 
1. Pogonomyia aterrima, sp.n. 3 @. (Tab. VIII. figg. 138, ¢; 13a, head 
‘in profile, ¢.)

Eyes occupying nearly the whole of the head in the male, separated by a broad front in the female; face 
shorter than the front; internal orbits narrowly white; oral margin and underside of the head thickly 
clothed with bristly hairs. Thorax, scutellum, and abdomen deep black, in the male with many hairs and 
macrochetz, in the female glossy and less pilose; abdomen in the male elliptical, with the first segment 
longer than the second, in the female pointed towards the tip. Legs black, slender, bristly ; foot- claws

ANTHOMYIA. 
Anthomyia, Meigen, in Illiger’s Mag. ii. p. 281 (1803). 
The genus Anthomyia, as restricted by Rondani (Dipt. Ital. Prodr. vi. p. 150) and 
Meade (Ent. Monthly Mag. xx. p. 109), includes only those species with the eyes 
bare, and nearly or quite contiguous in the male; the arista bare or microscopically 
pubescent; the abdomen of the male elongate, with the first segment longer than the 
second; the legs simple; the anal vein reaching, though sometimes indistinctly, the 
border of the wing; and the tegule unequal, the under scale being visible. 
Three Mexican species have been recognized by me, but from the male sex only; all 
are described as new :— 
1. Wings deep brown along the costa . . . . 1. 1 ee ee ew ee elongata. 
Wings not brown along the costa. 2. . 1 ww we ee ee 
2. Abdomen with black dorsal spots. . . . . 1. 2 1 ew ee ew eee dorsimaculata. 
Abdomen with a black dorsal stripe and transverse bands. . . . . . . segmentata. 
1. Anthomyia elongata, sp.n.,g. (Tab. VIII. figg. 14; 144, head in profile.) 
Thorax anteriorly whitish, with black stripes; abdomen long and narrow, hairy, grey, with a black dorsal 
line; antenne, palpi, and legs black; wings brownish.
