 Antennae reaching to the middle of the elytra or a little beyond ; 

 first joint barely reaching beyond the hind margin of the eye ; 

 third to tenth produced each into a sharp angle or tooth at the 

 apex on the anterior side. Pronotum rather closely punctured at 

 the sides, less closely in front and sparsely along the middle ; its 

 base with a rather deep sinuate emargination on each side and a 

 distinct lobe in the middle ; its hind angles projecting and acute. 

 Elytra subnitid, finely but somewhat sparsely punctured, the 

 interstices very minutely rugulose. Hind breast covered with a 

 tawny pubescence, giving silky reflexions in certain lights. Last 

 ventral segment subtruncate behind. 



5 . Antennae less than half as long as the body, more slender 

 than in the d 1 , the joints from the fifth to the tenth becoming 

 successively shorter and broader, produced each into a sharp 

 angle or tooth at the apex. Hind breast bare of pubescence. 

 Last ventral segment with rounded hind margin. Legs smooth 

 underneath .

 third of the elytra ; first joint reaching to a little beyond the hind 

 margin of the eye ; third and fourth not sharply edged in front 

 and not produced at the apex, fifth to tenth produced in a 

 short triangular tooth at the apex on the anterior side. Pro- 

 notum sparsely punctured, the punctures in the middle somewhat 

 finer than those at the sides ; its hind angles obtuse. Elytra
