OcNERA STJB LAEVIGATA. 
Habit of 0. imbricata , Eisch. Black, more or less obscure, legs, etc., fuscous, antennse and 
tarsi sometimes rufescent and clothed with ferruginous hairs, palpi and labium usually 
reddish. Head large, minutely and sparsely muricately punctured, and with minute simple 
punctures on the interspaces ; epistoma with a few coarse punctures at the sides and front : 
labrum coarsely punctured anteriorly : prothorax quadrate, a little transverse, front angles 
slightly prominent, sides very feebly rounded anteriorly, slightly, and sinuously, contracted 
posteriorly ; sparsely furnished with small, round, somewhat flattened umbilicate granules, and 
with some minute punctures scattered on the interspaces : elytra not wider at the base (which 
is sinuous) than the base of the prothorax, regularly oval and convex, gradually declivous 
behind, the apex a little produced ; on each elytra are seven more or less conspicuous rows of 
varying, but never large, granules, these being generally somewhat oblique, and pointed behind ; 
the 2nd, 4th, and 6th rows are the most apparent (the 6th being the most distinct of all), the 
others being more or less (especially at the base) confused with the granules scattered in the 
intervals ; the 6th row is also the most continuous (and the tubercles are placed more closely 
together), extending from the shoulder to near the apex; the others are abbreviated behind, 
where they are represented by minute distant granules ; the 4th and 6th converge towards' 
the base and are united at the shoulder ; the extreme outer margin is finely serrate ; the inter- 
vals are plain, sparsely and very minutely granulose : the epipleur® are loosely granulose : 
the flanks of the prothorax are sparsely granulose ; the pro- and meso-sterna are rather strongly 
granulose ; the metasternum with its flanks, and the flanks of the mesosternum are very minute- 
ly dispersedly granulose, and clothed with a fine cinereous tomentum : the abdomen, except in 
the middle, is more or less coarsely punctured, and with scattered granules : the prosternal 
process is broad, horizontal, and triangulate behind : tho femora are rugose and granulous and 
hispid ; the tibiae closely hispid, the posterior feebly sinuous ; the joints of the tarsi beneath 
are furnished at the apex with a tuft of bright fulvous hairs. 
Length 9 to 10 lines.

Bioramix, n. g. 
S . Head strongly transverse, front declivous to the epistomial suture ; epistoma very short, 
broadly rounded, or truncated, in front ; the angles distinct, or not ; marked off from the front 
by a well-impressed arched line : third joint of antennse as long as 4-5 united, or a little shorter : 
prothorax variable, always transverse, not closely applied to base of elytra ; sometimes very 
feebly convex and slightly narrowly depressed at the margins, or regularly convex direct from 
the margins ; apex strongly emarginate with the angles prominent and loosely embracing the 
head ( asidioides ) ; or very feebly emarginate, the angles depressed and more closely embrac- 
ing the head ; front angle sometimes acute, or more or less rounded ; base either truncate, 
or feebly emarginate, or sinuate, the angles prominent, or not, and either rectangular, obtuse, 
or rounded; sides sometimes more or less regularly rounded, or rounded in front and sub-
