row of punctures at extreme base, middle with short groove ; 

 clypeus separated at the sides by an elongate fovea, semicircularly 

 emarginate in front ; mandibles black ; antennae long and slender, 

 pale fulvous, apex of terminal joint thickened, piceous. Thorax 

 very short, strongly transverse, sides obtusely angulated near the 

 base, strongly obliquely narrowed anteriorly, anterior sulcus deep 

 and narrow ; surface very sparingly and finely punctured at the sides 

 only. Scutellum broad, iinpunctate. Elytra with a deep fovea 

 below base, the interior of which is black ; surface rather strongly 

 punctate-striate, punctures at the sides very strong, closely placed ; 

 a short oblique costa from shoulders to margins, interstices slightly 

 convex. Posterior femora with a distinct tooth beneath. 



Var. Elytra, the extreme base excepted, black. 



Length 3|-4 mm. 



Hab. Burma : Momeit. Type in Brit. Mus. 



Differs from N. cardoni, Jac. in the iinpunctate head and 

 nearly iinpunctate thorax, the black apex of the femora and the 

 want of the black sutural and lateral margins. In the female the 

 punctures at the sides of the thorax are rather more distinct (in some 

 males the entire thorax is nearly iinpunctate). Some specimens 

 have the elytral spots scarcely indicated, some entirely absent, but 

 the black apex of the femora seems constant. In one instance 

 the elytra are black, with the extreme basal margin only fulvous ; 

 whether this is the normal form or a variety of the one described 

 above I cannot say, the specimen agrees in every other respect 

 with the type.

Fulvous ; thorax with two large nearly connected discoidal 

 black spots ; elytra with a small piceous 

 spot within depression. 



Head strongly and closely punctured ; 

 clypeus not separated from the face, closely 

 punctured like the head ; antennas slender, 

 fulvous, terminal joints stained with 

 piceous, third joint half the length of 

 the fourth ; vertex of head sometimes 

 with a small piceous spot. Thorax rather 

 more than twice as broad as long, 

 sides rather strongly rounded, very obso- 

 letely angulate near base, anterior sulcus 

 entire; surface very finely and closely 

 punctured on the disc, sides more strongly 

 punctured, middle with a narrow longi-
