322 CHEYSOMELIDJE. 



shoulders with a short row of punctures on the inner sides. 

 Femora with a minute but distinct tooth. 



Length 4^ mm. 



Hab. Assam: Sylhet (Cott. Brit. Mm.). 



Amongst the larger species the present form may be known by 

 the nearly impunctate thorax, sparingly punctured elytra and 

 black legs. 



558. Nodostoma inconspicuum, sp. n. 



Obscure fulvous ; apical joints of antennae black ; knees and 

 bases of tibiae obscure fuscous. 



$ . Head remotely and finely punctured on vertex, very strongly 

 punctured on the clypeus, the latter not separated from the face ; 

 apex of mandibles black ; antennae long and slender, third and 

 fourth joints equal, basal four testaceous, rest progressively 

 darkening to black. Thorax scarcely twice as broad as long, sides 

 distinctly angulate near base ; anterior sulcus entire, strongly punc- 

 tured ; surface very strongly but subrernotely punctured, punctures 

 rather stronger at the sides. Elytra with deep basal depression and 

 prominent shoulders, very strongly punctate-striate, punctures finer 

 but distinct to apex, sides at shoulders with short oblique costa. 

 Femora with short tooth. Prosternum subquadrate, strongly 

 and remotely punctured. 



Length 3 mm. 



Bab. Assam : Patkai Mts. (Coll. Brit. Mus.). 



This form bears a close resemblance to N. duvivieri, but i& 

 rather smaller, the elytra are without the sutural black stripe and 

 are more distinctly punctured. The species may possibly be a 

 local form of N. duvivieri. 



559. Nodostoma subdepressum, sp. n. 



Fulvous ; terminal joints of antennae black. 



$ . Ovate, subdepressed. Head extremely finely and sparingly 

 punctured at base ; clypeus more strongly but remotely punctate, 

 scarcely separated from the face ; mandibles black ; antennas long 

 and slender, basal four joints flavous, rest black. Thorax strongly 

 .transverse, sides angulate near base, strongly obliquely narrowed 

 in front, anterior sulcus distinct and punctured at the sides only, 

 rest of surface strongly and remotely punctured, punctures ex- 

 tending to all the margins. Elytra deeply depressed below base, 

 .shoulders very prominent, deeply sulcate within, followed by 

 short oblique costse running to lateral margins; surface closely 

 and somewhat irregularly punctate-striate, punctures stronger 

 within depression and at the sides, two more regular and deeper 

 rows of punctures near suture, latter deeply sulcate near the 

 margins, interstices at the same place with some minute punc- 

 tures. Femora with a small tooth. 



LengtJi 4 mm.
