Two males and one female. They agree with the ample description of Low, except 
that in the male specimens the fore legs do not show any infuscation.

Ortalis atomaria, Wiedem. Aussereur. zweifl. Ins. ii. p. 461°. 
Hab. Mexico, Atoyac in Vera Cruz (H. H. Smith).—Braziu. 
Two male specimens. Wiedemann’s description is fully applicable to the Mexican 
specimens: they have the legs rufo-piceous, and thus agree with the variety mentioned 
by him, but the wings are coloured as in his type. 
The tibie of this species and of the closely allied J. trifasciata, Wied., have a 
preapical bristle, which is generally absent in the Ortaline. Both species possess all 
the other characters of this group, and they cannot be placed in any other. 
AMPHICNEPHES. 
Amphicnephes, Léw, Monogr. Dipt. N. Amer. i. p. 83 (1878). 
1, Amphicnephes stellatus, sp.n.,3 9. (Tab. X. fig. 23, wing.) 
Shining black; thorax with bluish reflections; wings black, hyaline at the tip and with hyaline dots. 
Length 4 millim. 
Front brown, fully as broad as the eyes and with parallel sides; face blackish, excavated; clypeus shining 
black. Antenne rufous, elongate, reaching to near the clypeus; third joint slightly attennated towards 
the tip; arista microscopically pubescent. Proboscis and palpi thick, blackish. Thorax shining bluish- 
black ; scutellum with four bristles, black, flattened, finely punctured, truncated behind. Abdomen ovate, 
shining black, punctured ; ovipositor of the female slender. Legs black ; the first joint of the middle and 
hind tarsi pale yellow. Halteres black. Wings broad, rounded at the apex, blackish, with a rather large 
hyaline patch at the tip and several hyaline dots; four of these dots along the costa are a little larger 
than the others, the first of them being placed at the end of the first vein, with a smaller one under it in 
the cubital cell, the second forming the commencement of a transverse row of dots; there are also several 
small dots in the basal cells and their neighbourhood ; small cross-vein on the middle of the discal cell, 
which is very broad; posterior cross-vein straight and long; third and fourth veins parallel; the third 
basal cell shorter than the second, and closed by a rounded cross-vein. 
Hab. Mexico, Chilpancingo in Guerrero 4600 feet (H. H. Smith), Northern Yucatan 
(Gaumer). 
Two males and two females. This species differs from A. obtusus, Low, by having 
the tip of the wing broadly hyaline (not black, with a hyaline cross-band), and by the 
want of clear dots in the central portion of the wing. I have no doubt that A. obtusus 
is synonymous with Trypeta pulla, Wiedem. (Aussereur. zweifl. Ins. ii. p. 506).
