DEGEERTA. 155 
In two other female specimens the small cross-vein is distinctly before the middle 
of the discal cell; but as they agree in all other respects with the above description, I 
believe they belong to the same species. 
10. Degeeria nervosa, sp. n., 2. 
Black; head, humeral spots, and narrow front margins to the abdominal segments whitish; palpi rufous ; 
“Wings somewhat infuscated. 
Length 3. millim. 
Head with white and grey reflections; front as broad as the eyes; frontal band black, as broad as the lateral 
portions ; frontal bristles descending to beneath the second antennal joint; vibrissee inserted at the oral 
margin. Antenne black, shorter than the face; second joint bristly ; third joint four times as long as 
the second ; arista thickened to the proximal half. Proboscis black, its terminal lips and the palpi dark 
rufous. Thorax and scutellum black; humeral spots and two short transverse lines before the suture 
whitish, these sometimes inconspicuous; pleure greyish. Abdomen ovate, shining black; second and 
following segments with scarcely visible narrow white front borders, and with discal and marginal 
macrochete. Legs black; middle tibie with some long bristles; hind tibie outwardly with several 
bristles of unequal length. Tegulze whitish. Wings rather broad, with a brownish-grey tint, more 
intense along the costa, and with black veins; small cross-vein on the middle of the discal cell; apical 
cell very narrowly opened at a little distance before the wing’s tip; apical cross-vein straight ; posterior 
cross-vein slightly concave, nearly midway between the small cross-vein and the curvature of the 
fourth vein. 
Hab. Mexico, Omilteme in Guerrero 8000 feet (7. H. Smith). 
A single female specimen. 
11. Degeeria albomarginata, sp. n., 2. 
Shining black; thorax anteriorly whitish, with four black stripes ; front borders of the abdominal segments 
whitish. 
Length 4 millim. 
Face and sides of the front whitish; frontal band black; frontal bristles descending beneath the second 
antennal joint; facial bristles mounting to the point where the frontal bristles terminate. Antenne 
shorter than the face; third joint four times as long as the second ; arista thickened to the proximal 
third. Proboscis and palpi black. Thorax anteriorly with a whitish tomentum, which does not reach 
the transverse suture and is interrupted by four black stripes. Abdomen elongate-oval; front borders 
of the second and following segments whitish, more conspicuously so at the sides; discal and marginal 
macrochete present, the discal ones, however, shorter. Legs, tegule, and wings as in D. magnicornis ; 
the apical cell very narrowly opened. 
Hab. Mexico, Cuernavaca in Morelos (H. H. Smith), Orizaba (H. H. Smith & F. D.G.). 
From each of these localities a single female specimen. 
12. Degeeria longipes, sp. n., 3 2. 
Black; face, some spots on the thorax, and front margins of the abdominal segments whitish; wings 
brownish (¢) or grey (9). 
Length 5 millim. . 
Front in the male much narrower than, in the female as broad as, the eyes, in both sexes almost wholly 
occupied by the black frontal band, the lateral portions scarcely forming two white reflecting lines; 
frontal bristles descending a little beneath the root of the antenne ; face and cheeks white, with blackish 
reflections ; vibrisse inserted near the oral margin; beard white. Antenne black, shorter than the face ; 
second joint bristly ; third joint four times as long as the second; arista thickened to the proximal half.
