Norr.—In the structure of the mandibles, the short antenne with a dilated basal joint, and the strong 
legs, this species recedes from the ordinary species of the Genus Epyris.

Grxnus—PRISTOCERA. 
(Klug, Weber und Mohr, Beitragen zur Naturkunde, 11 Bd. p. 202-6, pl. IV, fig. 8.) 
The Genus, as proposed by Dr. Klug in the work above quoted, comprised two species only (of which the 
males alone were known), namely— 
1. Pristocera depressa Fab., from Germany and Austria. 
2. Pristecera atra, from Georgia, in North America. 
Taking the former of these two insects as the type of the Genus, the following are its generic characters :— 
Mas alatus. Corpus oblongum depressum ; caput mediocre convexum; ocelli in medio verticis positi ; 
antenne longitudine thoracis et trientem abdominis «xquantes 18-articulate, articulo primo curvato crassiori 
punctato, secundo minuto, reliquis 11 subfiliformibus setosis aut pubescentibus; mandibule apice dilatate, 
5-dentate, dentibus acutis conicis, externo majori (fig. 8~); maxille lobis duobus apicalibus membranaceis 
ciliatis; palpis maxillaribus longis 6-articulatis, articulo secundo breviori (fig. 34); mentum obconicum setis 
4 rigidis antice armatum, labium internum membranaceum apice in medio emarginato; palpis labialibus triar- 
ticulatis articulis fere squalibus, longe setosis (fig. 3c); collare trigonum antice subtruncatum; scutellum 
convexum ; metathorax postice convexus, spatio magno dorsali trigono elevato plus minusve striolato ; abdomen
