DIOBYCTUS. 181 



Oblong, very convex. Head broad and rather flat, closely and 

 distinctly punctured ; clypeus not separated ; eyes feebly emargi- 

 nate ; antennae fulvous, not extending to base of thorax ( $ ), 

 joints very short, terminal joints widened. Thorax about twice 

 as broad as long, anterior half as wide as the posterior margin, 

 latter produced into an acute point at middle. Elytra finely but 

 distinctly punctate-striate, interstices flat, very finely punctured 

 in single rows, with other more minute punctures intermixed ; the 

 fulvous band placed near suture before middle, between first and 

 sixth rows, pointed posteriorly, not extending to apex, the latter 

 partially fulvous. 



Length 2 mm.

Larger than D. manipurensis, of different coloration and strong 

 el ytral puncturation, the fulvous band consists sometimes of three 

 nearly connected spots of elongate shape. 



311. Dioryctus abdominalis, sp. n. 



Black ; basal joints of antenna? and labrum dark fulvous ; elytra 

 reddish-brown, basal and sutural margins black ; abdomen pale 

 fulvous. 



Head minutely granulate, opaque ; antennae black, extending to 

 base of thorax, basal five joints small, more or less fulvous, rest 

 strongly transversely widened. Thorax strongly transverse and 

 widened at middle, anterior half the width of the posterior margin, 

 sides straight, surface with a transverse depression in front of 

 basal lobe, latter acutely produced ; surface microscopically punc- 

 tured, shining. Scutellum invisible from above. Elytra strongly 

 rounded and convex, epipleural lobes broadly produced, subangu- 

 late ; surface very finely punctate-striate, interstices sparingly 

 punctured. 



Length 2-J- mm.

The entirely pale chestnut-coloured elytra with narrow basa 

 margin and the fulvous abdomen distinguish this species, of which 

 a single male specimen was obtained by Doherty.

p. 327. 



Kufo -testaceous ; last six joints of antennae and all the ridges 

 on the prosternum and mesosternum piceous. 



Slightly longer than broad. Head very finely and closely punc- 

 tured ; clypeus large, semicircular, depressed ; last two joints of 

 palpi equal. Thorax strongly narrowed in front, sides but slightly 

 rounded, posterior angles acute, margin narrowly black, finely 

 serrate, surface slightly more strongly punctured than head. 

 Elytra finely punctate-striate, apex irregularly punctured. Ante- 

 rior margin of thoracic episternum strongly produced into a very
