DIOEYCTUS. 
181 
Oblong, very convex. Head broad and rather flat, closely and 
distinctly punctured ; clypeus not separated ; eyes feebly emargi- 
nate ; antennae fulvous, not exteuding 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.

Larger than B. manipurensis , of different coloration and strong 
elytral puncturation, the fulvous band consists sometimes of three 
nearly connected spots of elongate shape. 
311. Dioryctus abdominalis, sp. n. 
Black ; basal joints of antennge and labruin 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.

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.

liufo-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
