This insect has been sent to me by Mr. T. V. Ramakrishna 

 Ayyar, who found it in large numbers just beneath the 

 surface-soil in plantations of cinchona seedlings. 



It is moderately short and broad in shape, very smooth 

 and shining, with the metasternum densely clothed with 

 rather long tawny hair. The legs are not very long, the 

 front tibiae rather short and armed with three strong but not 

 sharp teeth, separated by acute notches. The clypeus is 

 small, very strongly and closely punctured, with the margin 

 regularly rounded and entire, and the forehead rugose, the 

 punctures coalescing, carinate at its posterior limit. The 

 pronotum is broad, not very convex, closely and rather 

 evenly punctured, with its lateral margins crenulated, angu- 

 lated in the middle, and nearly straight from there to the 

 front and hind angles, of which the former is a little produced 

 and the latter a right angle. The scutellum is broad and 

 almost unpunctured. The elytra are finely and moderately 

 closely punctured, with the sutural margins and two indistinct 

 discoidal costee smoother. The pygidium is also finely and 

 moderately closely punctured. The antennae are 10-jointed, 

 joints 3-7 very short and trausverse in the male and 8-10 

 forming a very long club more than twice as long as the 

 entire footstalk. In the female joints 3 and 4 are a little 

 longer than wide and the club is very short. The basal joint
