and pupate there. The beetle leaves the trees and appears on the wing 

 in the forests in March and April. 



I took the beetle on a sal-tree on 30 May 1906 in the sal forests near 

 Rajabhatkhawa, in the Buxa Duars. I have never yet found its larvae in 

 the sal-tree. 



Owing to the wide distribution of this buprestid, it is probable that the 

 insect infests a number of different kinds of trees. 



Chrysochroa. 



Differs from the last in having a transverse depression on each side 

 of the prothorax ; the under-surface of the body is metallic, with metallic 

 reflexions.

Description. the apex ; antennae purple ; under-surface 



metallic green with a coppery reflexion ; 



abdominal segments coppery, shining medianly, with a dense yellow 



pubescence at sides, where there is also a greenish reflexion. Head 



deeply and widely excavate, the excavation prolonged to meet the 



anterior margin of prothorax. Latter a little more than one and a 



half times as broad as long. Elytra wider than prothorax, truncate 



at shoulder, constricted at apex ; latter truncate, bidentate ; the suture 



and four raised costae on each elytron approaching each other 



towards apex ; the golden coppery band of colour runs chiefly between 



second and third costae, stretching into first and second near apex. 



Legs metallic green. Length, 34 mm. to 45 mm. ; breadth, 11 mm. to

Life History. wood of jarul {Lagcvstrouiia Flos- 



Rcginac) and chikrassi (Chickrassia tabularis) trees in 

 the Chittagong Hill Tracts together with the Catoxantha opulcnta already 

 considered. These two beetles evidently lay their eggs in the same trees, 

 and the larvae tunnel in the bast and sapwood in a similar manner, and 

 probably have a very similar life history. 



Since this insect has been recorded from Assansol (in Bengal) and from 

 the Bombay Presidency, it must infest several other species of trees.
