the head, sparse on the prothorax (each hair rising from a 
puncture), and rather dense and longest on elytra, on which also 
there are a few very indistinct grey hairs on the basal two- thirds; 
on the undersurface the pubescence is very short and greyish- 
black. Above densely and not very minutely punctate, the 
punctures strongest on elytra, sparsest on prothorax, and densest 
on head; the whole surface covered with microscopic punctures, 
most visible on scutellum; undersurface and femora densely and 
shallowly punctate, punctures densest on prosternum. 
Head rather dull, transverse, feebly transversely impressed 
between the eyes and antennae, and with a very indistinct median 
line; antennas short, immersed in prothorax to about the middle 
of its sides, 1st and 2nd joints somewhat large, between the 2nd 
and club the joints are very short and transverse; club slightly 
longer than the rest of antennae, composed of three joints, of 
which the 2nd is strongly transverse, it is about half the length of 
the 3rd (which is scarcely transverse), the 1st is transverse. 
Prothorax polished, strongly transverse, the sides narrowly 
margined, feebly depressed along the base; anterior angles slightly 
prominent, giving the apex a feebly emarginate appearance, which 
otherwise would be truncate; base shallowly bisinuate. Scutellum 
small, transverse, curvilinearly triangular. Elytra parallel-sided 
to near the apex, about one and a half times as long as wide, 
shoulders rounded, base feebly depressed on each side, suture 
feebly depressed at apex. Prosternum with antennal grooves 
broad, feebly strigose (to the naked e}^e appearing highly polished); 
keel narrow, feebly carinate. Metasternum with a feeble impres.- 
sion down its middle. Legs — especially the tarsi — slender-

I obtained my unique specimen under a stone in the nest of a 
small black ant; there were numerous larvae and a few pupae, 
most of which I left, hoping to procure some additional imagines on 
a future occasion.
