Antenna) slender and elongate, quite as long as head 

 and thorax, pale yellow, Avith the three or four apical 

 joints infuscate, the three a])ical ones distinctly thickened; 

 .'3rd joint more than twice as long as 2nd. Head with the 

 eyes almost broader than the elytra; the space between 

 the eyes slightly dejjressed, almost even, rather coarsely 

 and closely punctured, yet distinctly shining. Thorax 

 elongate and narrow, yet distinctly contracted behind the 

 middle, so that the sides in the middle appear a little 

 prominent; it is also slightly narrowed towards the front ; 

 it is densely and coarsely punctured and yet shining. The 

 elytra are rather narrow; they are scarcely longer than the 

 thorax, their sides are a little rounded, the humeral angles 

 quite prominent ; they are coarsely and not closely punc- 

 tured and shining, the punctures being fine and sparing 

 at the hind margin ; at the extreme base is a distinct 

 white pubescence. The hind body is slender and cylin- 

 dric, with only the basal segment mai'gined ; the four 

 basal segments are distinctly, but not coarsely nor densely 

 punctured, the apical ones obsoletel}' punctured ; each 

 segment has at the extreme base a distinct, whitish 

 pubescence. The legs are long and slender, very pale 

 yellow ; the tarsal lobes elongate and slender. 



In the male the ventral })late of the 7tli segment has a 

 very broad and deep incision ; the 6th segment is a little 

 flattened towards the extremity and finely ])unctured, and 

 with a fine, pale pubescence ; its hind margin is a little 

 eraarginate. 



A single male was found by Dr. Trail on the 5tli 

 November, 1874, but no special locality has been sent me.
