lus. From that level to the occipital border the punctures 
are much more widely spaced with the surface between 
them delicately coriaceous or reticulate and very feebly 
shining. The punctures on the genae and gula are notably 
smaller and more widely spaced than those on the front of 
the head. Both genae and gula are feebly shining. Clypeus 
and frontal lobes without distinct punctures and rather 
strongly shining. Mandibles with coarse, oval, piligerous 
punctures, the surface between them finely shagreened. 
Antennal scapes with numerous fine punctures, their sur- 
face more shining than the front of the head but less 
shining than the frontal lobes. Punctures on the thorax 
smaller, more shallow and more widely spaced than those 
on the front of the head, the surface between the punctures 
with a very delicate, reticulate sculpture. Pronotum and 
epinotum feebly shining. Scutum, scutellum, mesothoracic 
sternite and episternite a little more strongly shining. 
Punctures on the petiole very sparse and fine. Postpetiole 
and gaster with only a few, scattered, piligerous punctures. 
The delicate coriaceous sculpture becomes feebler as one 
passes from the petiole to the gaster and the parts become 
progressively more shining, with the gastric segments par- 
ticularly so. Fore femora laterally compressed. Middle 
and hind femora not laterally compressed. Both femora and 
tibiae with numerous, very small punctures which do not 
dull the shining surface. 
Erect hairs rather sparse over most of the body. Man- 
dibles and antennal scapes with moderately numerous, 
short, erect hairs. Those on the upper surface of the head 
and on the gula much sparser, widely separated and very 
irregular in length. Dorsum of the pronotum with six or 
eight erect hairs. Scutum and scutellum with about a dozen 
erect hairs of varying lengths. Epinotum without erect 
hairs. Petiole and postpetiole with eight or ten erect hairs 
each. These hairs are often, but not always, confined to 
the posterior half of each node. Erect gastric hairs largely 
confined to a broad band at the rear edge of each segment. 
Legs virtually devoid of erect hairs, except for one or two 
on the fore coxae and the fore femora. Tarsal joints and 
antennal funiculi densely covered with fine, semi-erect hairs
