 impressed and slightly sinuous on each side , nearly straight 

 in front of the scutellum , rather coarsely and closely punc- 

 tured, with a narrow smooth median line, strigose towards 

 the anterior angles , the sides with a marginal band of 

 pale golden hairs. Scutellum broad , nearly semi-circular, 

 with a few scattered punctures. Elytra broadest behind the 

 middle , rounded at the apex , each with six deep unevenly 

 punctured striae on the disk , the outer one shorter and 

 shallower than the others, the interstices convex and 

 sparsely punctured , the sides and apex closely and irre- 

 gularly strigose. Pygidium finely strigose, a spot at the 

 apex and three smaller ones placed transversely in the middle 

 of pale golden hairs; the penultimate dorsal segment 

 punctured, densely clothed with pale golden hairs and 

 with a narrow smooth median line. Underside strigose and 

 clothed with long pale golden hairs ; mesosternal process 

 short and compressed ; abdomen with a broad punctured 

 and pubescent central impression , a narrow space on 

 each side smooth and shining , the apical segment finely 

 and sparsely punctured. Legs coarsely punctured , the femora 

 pubescent, anterior tibiae with a slight indication of a 

 lateral tooth. 



The female is rather broader than the male and has 

 the apex of the pygidium covered with small tubercles 

 and without hairs , the abdomen is convex and smooth 

 in the centre and the anterior tibiae are furnished with 

 an acute lateral tooth. — Length 21 — 23 mm. 



Hah. N. Manipur, Assam (5000 to 8500 ft. elevation). 



This fine and very distinct species differs from all 

 others of the genus in its robust and convex form , 

 strongly costate elytra and deeply notched labium , the 

 thorax is also narrower and scarcely lobed at the base, 

 the intermediate tibiae are but slightly curved in the 

 male and the club of the antennae is of the same size in 

 the two sexes.
