tonsa ; but, ordinarily, this lateral calus is situated inside of the 

 curve which prolongs the lower border. 2nd. — A homeomor- 

 phous $ remarkable for the singular mixture of the $ and ? 

 characters. Its forehead is slightly turned up in front as in the ? 

 and clothed in the middle as in her case with a light-coloured 

 close pubescence but the area over which this is spread is less than 

 in the ? . The prothorax, which in its general form and size is that 

 of the normal $ has no horns. In their place on each side there 

 are present two teeth, turned up and placed close together of which 

 the inner one is slighly narrower than the outer ; between these teeth 

 the anterior edge is slightly indented. The elytra are also by their 

 size the elytra of the $ but they have no marginal callosities on the 

 lateral edges of their apical declivity and the two callosities of the 

 upper edge are hardly perceivable. Below the declivity shows a pro- 

 minent and thick border, diverging laterally from the edge of the 

 elytra. 3rd — A series of forms, also homeomorphous, in which the 

 head and the prothorax are shaped as in the preceding 6* in all 

 except that at times the inner tooth of the anterior angle of the 

 prothorax is absent, but in which the apical declivity of the elytra is 

 furnished with marginal callosities more or less prominent. 



Distribution. — Indian Region. Throughout the Deccan, Central 

 Provinces (Raipur) ; Chota Nagpur (Singbhum) ; Bengal; Assam.

Life-History. — This insect was found boring in June into cut 



<and stacked bamboos [Dendrocalamous strict us) by the late Mr. 



A. M.Long of the Imperial Forest Service in the Raipur Forests 



of the Central Provinces. The beetle was probably egg-laying in 



the bamboos. 1 



Mr. Lesne mentions that Querin-M6neville found it in the roots 

 of Srnilax china* This appears to be all the information at present 

 available on the life-history of this insect. 



A live specimen was brought to rr.e to the Museum in Calcutta 

 about the middle of May of this year (1903). It was found in a street, 

 This proves that it is on the wing in May in this locality.

 yeli (An. Fr., 1845, Bull. p. xvi) 5 of which he published no descriptio .
