318 CHKYSOMELID^. 



Length 3-3^ mm. 



Hab. Travancore : Wallardi (Coll. ,7oc<%). 



A variable species in regard to colour, the head either entirely 

 or partly pale and black, thorax sometimes entirely black, 

 strongly punctured. The puncturation on the elytra in 

 the depression separates this species from some of the similarly 

 coloured varieties of N. variabile, Duv. (mandarense, Jac.). N. 

 geniculatum, Lefev., in some of its varieties resembles the present 

 insect in coloration, but may be distinguished by the extremely 

 finely and closely punctured thorax. 



549. Nodostoma lewisi, Jac . P. Z. S. 1887, p. 77. 



Fulvous ; elytra testaceous ; terminal joints of antennae and 

 sutural and lateral margins of elytra narrowly black. 



Head shining, fulvous, with a few punctures at base and between 

 the eyes ; antennae long and slender, basal four joints tlavous, rest 

 black, third and fourth equal, rest not thicker. Thorax about 

 half as broad again as long, sides distinctly angulate near base, 

 strongly obliquely narrowed anteriorly, sulcus distinct at sides 

 only, surface very strongly and rather closely punctured, interstices 

 more or less convex. .Elytra oblong, distinctly transversely de- 

 pressed below the base, the latter only distinctly punctured, rest of 

 surface nearly impunctate. 



Length 2 2| mm. 



Hab. Ceylon : Dikoya. 



In some specimens the thorax has the disc more or less piceous, 

 and the black sutural stripe varies somewhat in width. 



550. Nodostoma bengalense, Duviv. Bull Soc. JEnt. Bely. xxxv, 



1891, p. xxxviii. 



Fulvous ; elytra with the suture broadly and apical portion of 

 lateral margins more or less black. 



Head with a few tine punctures ; clypeus separated at the sides by 

 a fovea, surface with a few punctures ; antennae filiform, fifth and 

 following joints more or less darkened, third joint shorter than the 

 fourth. Thorax about twice as broad as long, distinctly angulate 

 at sides near base, anterior sulcus well marked and strongly 

 punctured ; surface with a few very fine, widely separated punc- 

 tures. Elytra with strongly raised base, deeply depressed below that, 

 bearing some deep punctures within the depression, rest of the 

 surface nearly impunctate, sutural portion with some rows of fine 

 punctures. 



Var. Elytra entirely fulvous or flavous. 



Length 3|-4^ mm. 



Hab. Bengal : Konbir-Nowatoli ; Burma : Toungoo. 



The nearly impunctate thorax and only partly punctured elytra 

 are the principal characters that separate this species from N. nigro-
