ticatory margin irregularly serrate. The straight inner 
margin of the mandible meets the masticatory margin at a 
sharply marked angle. Eyes oval, of moderate size and 
rather strongly convex with their posterior borders lying 
slightly in front of the middle of the side of the head. 
Frontal carinse prominent and subparallel, their lateral por- 
tions in the anterior half turned upwards so that from above 
this part of the carina appears narrow and welt-like. An- 
tennal scapes long, slender and evenly though slightly 
curved outward. In repose they surpass the occipital border 
by one-third their length. The base of the scape is strongly 
spatulate. Funiculus filiform, joints 1 - 7 all of about the 
same length and diameter and all several times longer than 
broad, joints 8-12 somewhat broader than the preceding 
joints and slightly increasing in diameter apically. 
Dorsum of the pronotum in profile feebly convex. Just 
posterior to the promesonotal suture the mesonotum is 
abruptly elevated. This elevated portion, which is flat on 
top, occupies the anterior half of the mesonotum and passes 
to the posterior half through a short and abruptly descend- 
ing declivity. The posterior half of the mesonotum, which 
is also flat on top, is slightly if at all higher than the adja- 
cent portion of the epinotum from which it is separated by 
a narrow U-shaped impression at the mesoepinotal suture. 
Epinotum in proiile angular, the basal face, which is straight 
and slopes slightly to the rear, twice as long as the almost 
perpendicular declivious face. The angle between the two 
faces is armed at either side by a short, rather blunt tooth 
with a very wide base. Seen from above the pronotum is 
subpentagonal with the lateral portions carried back past 
the anterior half of the mesonotum so that the latter has the 
appearance of being a part of the pronotum. Just behind 
the pronotum the sides of the mesonotum are slightly con- 
stricted. There is no constriction of the sides at the meso- 
epinotal suture other than the very shallow incision formed 
by the suture itself. Seen from above the dorsal face of the 
epinotum bears a shallow longitudinal sulcus extending
