COLEOPTERA. 69 



OCNEEA SUBL^VIGATA. 



Habit of 0- imbricata, Fiscb. Black, more or less obscure, legs, etc., fuscous, antennae 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 epipleurse 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 : the 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. 



$ . 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 antennae 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-
