transverse carina upon the clypeal suture ; they may be 

 distinguislied by the front tibice, wliich, in the male, are 

 elongate, slender, and strongly curved, with the teeth feebler 

 and farther apart. The specimens of the luridus form are 

 all males. The three forms have been taken together in 

 Ceylon and Travancore, where they appear to be common. 

 I have only seen a single female from Java, and there is a 

 single male in our collection from Darjeelinu,-, while Dejean 

 gives China as the habitat of the var. luridus, so that the 

 species has evidently a very wide range.

Long. 9-5-] 3 mm. 



Hah. S. India, Xilgiri Hills, Belgaum. 

 Black and shining, with the antenna3 and tarsi reddish. 

 The prothorax is finely but not closely punctured all over, 

 except upon the anterior declivity, and the elytra are sulcate, 

 with the interstices convex and scarcely punctured. The 

 pygidium is sparingly punctured and the median part of the 

 metasternum has only a very few punctures near the sides. 

 The spur of the front tibia is bent at a right angle and acute. 



(J . The head is octagonal, slightly emarginate in front 

 and iinpunctate except just in front of the eyes. There is a 

 distinct carina upon the clypeal suture, and two slender, 

 unconnected horns arise almost vertically from the back of 

 the head, with a slight forward curvature. The prothorax 

 is very short and broad, vertical and smooth in front, very 

 convex and distinctly punctured behind, with the anterior 

 edge of the dorsal part carinated in front and the ];03terior 

 edge curved, finely margined and not angulated. The trout 

 tibial spur is broader than in the female. 



? . The clypeus is curvilinear and very feebly emarginate
