 Beeson in Bengal : — 



Xyleborus comptus, sp. n. 



Cylindrical, dark brown, with prothorax paler than the 

 elytra. Front convex, rugose, with slight fringe over the 

 mouth. Prothorax subglobose, sides slightly and front 

 strongly rounded, anteriorly asperate to the transverse node 

 and posteriorly faintly punctate. Elytra less than one-third 

 longer than the prothorax and slightly narrower, the sides 

 nearly parallel and obtusely rounded at the apex ; the striae 

 are furnished with large but shallow depressions, which 

 decrease in size towards the base, the interstices are slightly 

 convex with uniseriate punctures, except the second which 

 is biseriate up to the declivity and deeply depressed towards 

 the apex, the elytral declivity is semiopaque. 



Long. 26 mm. 



Hab. Ceylon (E. E. Green). 



Food- plant, Hevea brasiliensis. 



Xyleborus undulatus, sp. n.

 pilose. Front dark and subconvex, sparsely punctured on a 

 reticulate surface with a longitudinal carina extending half- 

 way to the vertex, the mouth thinly fringed, eyes deeply 

 emarginate. Prothorax slightly longer than broad, strongly 

 rounded apically and much less so laterally, transversely 

 scabrous as far as the prominent transverse gibbosity, poste- 

 riorly finely reticulate and sparsely granulate and hairy, 

 paler in colour than the elytra and with a faintly marked 

 longitudinal median smooth space from the base to the 

 transverse ridge. Elytra about one-fourth longer than the 

 prothorax and of equal breadth at the broadest part of each, 

 with a transverse depression commencing near the base and
