border, and without posterior angles. Eyes a little in front of the 
middle of the sides of the head, rather large, very convex, hemi- 
spherical. Clypens convex, its anterior border feebly and sinnately 
excised in the middle. Antennse rather stout, scapes reaching a little 
beyond the posterior border of the head, funicular joints 1 — 5 at 
least twice as long as broad, remaining joints, except the last, less 
than twice as long as broad. Thorax long, deeply constricted in the 
mesoepinotal region. Pronotnm flattened above and on the sides, at 
least twice as long as broad, its raised anterior border high and

broadly rounded, its humeri scarcely angular. Mesosternnm armed 
at its base on the anterior border with a blnnt tooth, which is di- 
rected down ward and forward. Mesonotum fully twice as long as 
broad and nearly twice as broad in front as behind. Base of epi- 
notum rising abrnptly in profile in a convex cnrve, terminating behind 
in a sharp border, whence the longer declivity slopes downward and 
backward. Seen from above the base of the epinotum is slightly 
longer than broad, very narrow in front and rapidly broadening be- 
hind, with convex lateral and posterior borders. Petiole rather high, 
its node placed anteriorly and inclined forward ; in profile it is cuneate, 
with feebly convex anterior and posterior surfaces and rather blunt 
npper border. Seen from above the petiole is about 2 / 3 as broad as 
the base of the epinotum. Gaster large, with a slight constriction 
between the first and second segments. Legs long and slender. 
Surface shining; mandibles coarsely punctate and finely striate, 
at least at the base. Clypeus sharply, longitudinally rugose. Head, 
pro- and mesonotum and base of epinotum covered with large, deep, 
circular or slightly elliptical foveolse. These are somewhat shallower 
on the mesonotum. Neck transversely rugose. Petiole and declivity
