elytra ; first joint stout, strongly punctured and sparsely ciliate ; 

 third shorter than the fourth, slightly 

 nodose at the apex ; fourth to tenth sub- 

 equa.1 in length, eleventh longer than the 

 tenth ; each joint from the fifth or sixth 

 with a feeble longitudinal channel in front 

 and another behind near the lower border. 

 Prothorax with a broad dark channel or 

 depression along the middle bearing four 

 or five longitudinal ridges ; the sides red- 

 dish, strongly rugose-punctate, furnished 

 like the head with some longish setae. 

 Elytra sparsely setose, each with two 

 dorsal carinae and one lateral, also about 

 eight rows of strong punctures, some of 

 the rows long, some short, the intervals 

 between them shghtly i-aised; none of 

 the rows or carinae extend to the apex ; 

 apical part closely and very finely punctulate. Apex of femora 

 and base of tibiae blacldsh ; femora with large sparse punctures, 

 the hind pair asperate beneath. 



This is a very rare species, of which I have seen only three 

 examples, two in the collection of M. Eene Oberthiir and one in 

 the collection of Mr. Fry. In the smaller specimen, from Ivurseong 

 in Sikhim, the antennae extend to the middle of the elytra, while 

 in the larger one, ticketed "India" and probably the type, they 

 do not extend beyond the anterior third of the elytra. The 

 difference is probably sexual. 

 Length 16-22 mm.
