152 FAMILY BOSTRYCHIDAE 



cJ Front of head transversely convex, finely and densely punctate, and finely pubescent, 

 with a few scattered stiff hairs, more numerous near the eyes. 

 9 Frontal crown circular or broadly V-shaped. 



I have not taken this species in India. In July 1903 Mr. E. Ernest 



Green, Government Entomologist, Ceylon, forwarded 



Life History. some specimens to me at the Indian Museum, Calcutta, 



with the information that the insect tunnelled into the 



stems of cocoa-trees in Ceylon.

Habitat. Nellore, Madras. 



Tree Attacked. Casuarina (Casuarina equisetifolia). Nellore. 



Beetle. Black with parallel sides and a uniform breadth throughout 

 of three-sixteenths of an inch, perhaps a little less anteriorly and a little 



more posteriorly. Body more than twice length 

 Description. of prothorax ; latter rounded and pitted above ; 



elytra with longitudinal ridges running down 



their dorsal surfaces with punctures between ; elytra deflexed at their 

 apices. Abdomen red beneath. Legs black, short. Antennae with a 

 club. Length, \^ in. 



This beetle is a wood-borer, and tunnels into the wood 



of the casuarina for egg-laying purposes.

Walker. Madras. Llfe History. It was reported by the District rorest 



Officer as boring into trees in planta- 

 tions at Nellore in June 1903, and therefore the eggs of one of the 

 generations of the year are probably laid in that month. Nothing further 

 appears to be known about its life history. 



In all probability the beetle does not attack the tree until it is either 

 felled or has from some cause become sickly. The damage done is to the 

 timber ; in cases where the insect is numerous and the wood is required for 

 planks or beams, the tunnelling of the beetle and its grubs, who also feed in 

 the wood, would cause a considerable loss. 



The length of time spent in the larval and pupal stages and the number 

 of generations in the year have yet to be ascertained.

Sinoxylon crassum, Lesne.
