Black, the .surface dull above and beneath, but the abdomen 

 and h>gs shmmg, the soles of the tarsi and the inner face of the 

 middle and hind tibiae of the male densely clothed with short, 

 bright yellow hairs. Rather short and broad, with the legs 

 fairly long. The head, sides of the pronotum and elytra 

 entirely opaque, the middle of the pronotum, the scutellum and 

 the sutural margins of the elytra a little less so. The front 

 angles of the pronotum blunt, the sides very gently curved 

 to the lateral angles, which are strong but not acute and 

 almost level with the base, then rather strongly concave to the 

 hind angles, which are acute. The sides of the elytra rather 

 strongly rounded and a little flattened. The prosternum 

 strongly compressed behind, a little produced and pointed. 



$. The head is short, rugose in front, with the margin not 

 excised, the canthus angularly-produced and the side without 

 process behind the eye. There are fine punctures upon the 

 middle part of the pronotum and the inner posterior part of the 

 elytra. The abdomen is rather strongly punctured beneath. 

 The lateral teeth of the front tibia are minute and the tip is 

 rather feebly forked. 



^. The front of the head is excised, the canthus rounded or 

 very slightly prominent laterally and there is a strong pointed 

 process behind the eye on each side. The lateral angle of the 

 pronottim, is rather sharper than in the female. The lower 

 surface is almost unpunctured. The prosternal process has an 

 oblique direction. The front tibia is shortly but sharply 

 forked at the end. All the tibial spurs are very short and that 

 of tlie front tibia and the lower ones of the middle and hind 

 tibiae are hooked. The tarsi are long. 



Variation of the male. The j^ostocular processes of the head 

 are sharp in small specimens and become broader and blunter 

 with increasing size. The mandibles in small examples are 

 very short, with their inner edges in close contact and irregu- 

 larly toothed. In medium-sized examples they are rounded 

 externally and a gap occurs between the two or three basal 

 teeth and those succeeding, which remain in contact. With 

 increase of size the gap becomes longer and the terminal teeth 

 become fewer. In the largest specimens the mandibles are 

 slender and capable of (contact only at the base and extremity, 

 the latter usually composed of four minute teeth.
