before the transverse suture with cinereous tomentum and indistinct black lines. Abdomen conical, the 
second and following segments laterally with white front borders, and with macrochete at the hind 
margins. Legs black, with some weak bristles; the tarsi as long as the tibie ; foot-claws and pulvilli 
elongate, the pulvilli yellow. Tegule brownish. Wings with a brownish tint, more obscure on the 
apical half of the costa; small eross-vein a little beyond the middle of the discal cell ; curvature of the 
fourth vein angular; apical and posterior cross-veins slightly concave, the posterior in the middle between 
the small cross-vein and the curvature of the fourth vein. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith). 
A single male specimen. 
COMYOPS, gen. nov. * 
Head hemispherical; front narrow, trigonal (3); eyes distinctly pilose, contiguous on the vertex (¢), 
descending nearly to the lower part of the head; face nearly perpendicular, not carinated ; vibrissal 
swellings parallel or even somewhat divergent towards the oral margin, the vibrisse at or a little above 
the margin. Antenne inserted in a line with the centre of the eyes ; third joint longer than the second ; 
arista long-plumose. Proboscis short and thick, with large terminal lips; palpi cylindrical. Abdomen 
conical, with marginal macrochzte only. Legs of moderate length, with scattered bristles ; foot-claws 
and pulvilli elongate (¢). Wings longer than the abdomen; apical cell narrowly opened at the wing’s 
tip; curvature of the fourth vein rounded ; posterior cross-vein in the middle or a little beyond the middle 
between the small cross-vein and the curvature of the fourth vein. 
This genus agrees in most respects with Morinia, but differs from it by the hairy 
eyes. I include in it two Central-American species, of which male examples only are 
known to me. 
1. Comyops nigripennis, sp.n.,¢. (Tab. VL. figg. lo; 15 a, head seen from 
in front; 15 6, head in profile:) 
Black ; abdominal segments with obsolete whitish front margins; tegule and wings blackish. 
Length 6°5 millim. 
Head black, with greyish reflections; frontal band black, trigonal; eyes densely covered with a yellowish 
pile. Antenne nearly as long as the face; third joint three times as long as the second ; arista thickened 
at’ the base. Proboscis and palpi black. Thorax, scutellum, and abdomen deep black; second and 
following abdominal segments with traces of narrow whitish front margins, and with rather long macro- 
cheete: at the hind margins. Legs black; middle and hind tibie with some long bristles ; foot-claws and 
pulvilli somewhat elongate, the pulyilli yellowish-grey. Tegule blackish-brown. Wings blackish, more 
intensely so towards the base and costa; small cross-vein on the middle of the discal cell; apical cross- 
vein concave; posterior cross-vein slightly curved. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith). 
Two male examples.
