Genus ROTHNEYIA Cameron 
Three species have been referred to this genus by Cameron, 
all from India, while Schmiedeknecht records one of them also 
from Java. The second species described, annulicornis Cameron, 
differs so markedly in structural characters from the others that 
one wonders, not having examined it, if it is properly placed 
in the genus. These differences are brought out in the follow- 
ing key to the species. The new species tabulated and described 
below is apparently typical of the genus.

Rothneyia insularis sp. nov. 
Male.—Length, 6 millimeters; antennz, 4.5; front wing, 4.5. 
Head transverse, in front view roundly triangular, temples 
slightly convex, sharply sloping; frons with large, separated 
punctures, the middle narrowly polished, impunctate; vertex 
very sparsely punctate; face densely, confluently punctate, be- 
coming striately so in middle; clypeus sparsely punctate, not 
separated from face by a furrow but by difference in sculpture, 
longer than face, gently convex and rather sharply rounded 
at apex; malar space two-thirds as long as basal width of man- 
dible; eyes convergent to level of antennz, thence parallel, 
slightly sinuate above antenne; antenne distinctly shorter than 
body, basal three joints of flagellum subequal and each scarcely 
longer than scape, the flagellum attenuate at apex; postocellar 
and ocellocular lines equal and distinctly longer than diameter 
of ocellus. Thorax opaque dorsally and ventrally, shining later- 
ally; pronotum polished with a few ruge posteriorly and sparse- 
ly punctate above, epomia distinct but fading out below dorsal 
margin; mesoscutum densely punctate, notauli distinct anterior- 
ly, lateral lobes flanked by a deep groove laterally; scutellum 
rugose, posterior angles very high and prominent, apical slope 
abrupt, with a few longitudinal ruge, lateral areas polished,
