88 LARRIDE. 
The ¢ differs in having the pubescence thicker in the face ; 
the wings less coloured; the legs less spinose, and the abdomen 
entirely opaque, caused by its being wholly covered with mi- 
nute punctures ; and the margins of the segments broadly co- 
vered with the sericeous pubescence.

Genus XIV. Tacuytes. Panz. 
Heap transverse, depressed in front, a little wider than the 
thorax, with a depression on each side of the face, at the base 
of the clypeus, extending half way to the vertex, bending in 
a slight curve from the eyes to the base of the antenne, 
covered, as also the clypeus, sparingly in the ¢, but more 
densely in the , with an aurichalceous pubescence ; eyes 
oval, converging at the vertex; stemmata placed low, but 
within the return of the interior margin of the eye, the an- 
terior one somewhat lower, the posterior pair obsoleto-con- 
fluent ; antenne filiform, inserted at the base of the clypeus, 
the basal joint gradually incrassate, obconical, the rest cylin- 
drical, the second short, and the apical one acuminate, the 
whole slightly covered with a silvery pubescence ; the clypeus 
transverse, the anterior margin inflexed, with the edge sud- 
denly reflexed ; labrum concealed; mandibles large, arcuate, 
acuminate, with a dentate process on the exterior, towards 
the base. THorax oval; the collar almost concealed beneath 
the gibbosity of the anterior part of the mesothorax ; the 
scutellum transverse; the metathorax posteriorly truncate, 
nearly as broad as long; superior wings mith one marginal cell 
slightly appendiculated, and three submarginal cells—the first 
and second subequal, and the latter contracted towards the mar-
