LUTEVA.—PLOIARIOPSIS.. 173 
America; one of these has been recorded by Stal from Mexico. In Luteva the anterior 
tarsi are long and claw-like and not articulated, the anterior femora are armed from 
the base with a row of closely placed slender spines, the anterior trochanters are armed 
with one or two slender spines or sete, the pronotum is completely separated from the 
mesonotum, the latter covering the mesothorax and extending forwards, and the elytra 
reach the apex of the abdomen.

PLOIARIOPSIS, n. ven. 
Head short, broad, subcylindrical in front, transversely convex behind, without frontal spine, the eyes large 
and prominent ; rostrum 3-jointed, the two basal joints short ; antenne exceedingly slender, longer than 
the body, the two basal joints very elongate. Prothorax short, subquadrate or narrowing behind, the 
basal margin raised and dilated, forming a collar for the reception of the mesothorax. Mesothorax 
extending forwards, twice as long as the metathorax, covered by the mesonotum, which is subconical and 
longer than the pronotum. Scutellum without spine. LElytra extending to far beyond the abdomen, the 
spaces between the main nervures closely reticulate. Abdomen narrow. Anterior coxe elongate, longer 
than the tibie. Anterior trochanters armed with one or two long spines. Anterior femora as long as 
the tibia and tarsus united, slightly curved at the base, armed on the lower side with two rows of long 
spines, which extend from the base to near the apex, the spines on one or both edges arising from a series 
of conical teeth. Anterior tibize comparatively short. Anterior tarsi a little shorter than the tibix, slender, 
formed by three connate joints, and with a single claw. Intermediate and hind legs very elongate, the 
hind femora extending to far beyond the apex of the elytra. Body elongate, very slender, winged. 
Two small species are referred to this genus. These insects have the facies of 
Ploiariodes, but with the general structure more nearly agreeing with that of Luteva, 
from which they differ in the closely reticulated elytra and the peculiar armature of 
the anterior femora. The pronotum is short, the mesothorax being entirely covered 
by the mesonotum. The anterior tibiz in repose are received between the two rows 
of long spines which extend along the lower edges of the femora, these spines arising 
(on one or both edges) from prominent conical teeth. The antenne have their two 
basal joints clothed with very long projecting hairs. 
The two species may be differentiated thus :— 
Head distinctly bituberculate between the eyes, with a short erect spine on the 
basal declivity, the eyes very large; mesonotum deeply sulcate; anterior 
femoral spines much shorter than the tarsi; intermediate and hind femora 
conspicuously annulate towards the apex. . . . . . . . « «+ «) «megalops, n. sp. 
Head not distinctly bituberculate between the eyes, with an interrupted carina 
behind, the eyes smaller ; mesonotum shallowly sulcate ; anterior femoral 
spines nearly as Jong as the tarsi; intermediate and hind femora speckled 
with fuscous. 2... 1 we ee ee ee ee ww eee predator, 1. sp.
