PRIOTYBAKNUS. 21 



to the ends of a transverse basal band that is dilated to form an 

 anterior angle in the middle ; two additional less nitid spaces on 

 each side placed obliquely one before, the other behind the middle ; 

 rest of the surface finely and very closely punctured and dull. 

 Elytra minutely coriaceous, rather dull, finely and very sparsely 

 punctured near the base, armed each with a very small apical 

 spine at the sutural angle. Metathorax and hind coxae closely 

 and rather finely punctured, densely covered with reddish-brown 

 pubescence. Hind tarsi longer and narrower than the middle 

 ones, these longer and narrower than the front ones ; third joint 

 cleft halfway in the hind tarsi, and more than halfway to the base 

 in the front and middle tarsi. Last ventral segment broadly 

 sinuate at the apex. 



$ . More of a reddish-brown colour, especially on the elytra 

 and antennae. Antennas smooth, nitid ; the third joint sparsely 

 punctured, the succeeding joints almost impunctate. Elytra 

 subnitid. Metathorax and hind coxae punctured almost as in the 

 male, but less densely pubescent. Palpi like those of the male, 

 with the last joint of the labial as strongly thickened. Last ventral 

 segment rounded at apex. 



Length 44-54; breadth 15-20 mm.

c? . Head large, broadly concave between the antenniferous 

 tubercles ; clypeus bounded behind by an arcuate groove ; eyes 

 deeply emarginate, with the upper lobes rather narrow ; mandibles 

 dimorphic, either (1) long and sickle-shaped with a wide cordate 

 space between them when closed, armed each with one large 

 and a few smaller teeth close to the tip, or (2) like those of 

 the female. Antennae longer than the body, 11-jointed; first 

 joint stout, subcvlindrical, nearly twice as long as broad, third and 

 succeeding joints finely punctulate and opaque, fifth to tenth 

 furnished each with a small tooth at the apex. Pronotum strongly 

 transverse, with three spines on each side, the first near the front 

 angle, the second and longest at the middle, the third at the hind 

 angle ; anterior margin rounded in the middle, sinuate at each 

 side, projecting forward in a small spine or tooth at the point 

 where it joins the lateral edge. Elytra much less than twice as 

 long as broad, rounded at the apex. Prosternum very short and 

 strongly sloping in front of the coxae, the iutercoxale rather strongly 

 arched. Legs long ; femora compressed, somewhat parallel-sided ; 

 tarsi long, with the first joint longer and narrower than the 

 second or third, the third deeply bilobed, the claw-joint as long 

 as the first two together. Last ventral segment sinuate at the
