NODOSTOMA. 313 



plain, irregularly wrinkled on the sub-basilar depression. Femora 

 with an acute tooth. 



Var. Thorax piceous, elytra black. 



Length 4 mm. 



Hab. Kashgar ; Jhelam Valley ; Bengal : Mandar. 



Principally distinguished by the strong puncturation of thorax 

 and elytra, and the comparative length of the joints of antennae. 



539. Nodostoma duvivieri, sp. n. 



Fulvous ; thorax with two black bands ; elytra with a sutural 

 black band from base to behind the middle, pointed at apex. 



Oblong. Head nearly impunctate ; clypeus with a few remote 

 punctures ; antennae long and slender, fulvous. Thorax twice as 

 broad as long, sides angulate behind the middle, obliquely nar- 

 rowed to apex, anterior sulcus distinct at the sides only ; surface 

 strongly but remotely punctured on the sides, disc more sparingly 

 punctured, a broad black patch from base to apex occupies almost 

 the entire sides. Elytra oblong, with distinct depression below the 

 base, rather strongly punctate-striate on the anterior two-thirds, 

 apex nearly impunctate. Femora only moderately thickened, 

 unarmed. 



Var. Thorax without bands. 



Length 3-3| mm. 



Hob. Burma : Momeit ; Ruby Mines. Type in Brit. Mus. 



Although very closely allied and of very similar coloration to 

 N. beiiyaleiisis, Duviv., the present insect differs in the compara- 

 tively strong puncturation of the thorax and elytra, these parts 

 being nearly impunotate in N. bengalensis. The specimens I take 

 to be females are of broader and more subquadrate shape and have 

 no markings on the thorax ; in other respects they are identical 

 with the males. 



540. Nodostoma bistrigatum, sp. n. 



Testaceous ; thorax with central black spot ; elytra with sutural 

 and lateral margins and a longitudinal short stripe at middle, 

 black. 



Head strongly but remotely punctured on the vertex ; very 

 closely punctured on the clypeus; basal four joints of antennae 

 testaceous, following two black, rest wanting in the type and 

 only specimen. Thorax about half as broad again as long, sides 

 angulate near base, anterior sulcus obsolete except at the sides, 

 surface remotely and strongly punctured. Elytra oblong, sub- 

 cylindrical, deeply depressed below the base, strongly punctate- 

 striate anteriorly, more finely punctured behind the middle, inter- 

 stices sparingly punctured, the black streak placed below depression 

 between third and fifth rows of punctures. Femora unarmed. 



Length 3i ram. 



Hub. Ceylon (Coll. Jacoby).
