l\ilvous red, with the elytra green, 

 the anteniiJe and leps (the stalks of 

 the femora excepted) nearly black ; 

 body beneath and legs glossy, upper 

 surface opaque. Scutellum acute, 

 but not prolonged, at the apex. 

 Elytra closely punctured, sharply 

 roixnded and unarroed at the apex, 

 each with a small sharp tubercle at 

 the extreme base. 



Length 14-17 ; hrcadth 3^-4^ mm. 



Hah. Burma; Siara. 



This species is very closely allied 

 to N. fuscijoennis ; almost the only 

 difference is in the colour of the 

 elytra, which is distinctly green m 

 the one, brown in the other.

Nearly allied to iVv/^Jm&m, Base, with which it agrees m tie 

 structure of the antenna? and legs; also, like that genus, it has 

 the acetabula of the middle coxa? shut off from the epimera by a 

 prolongation of the antero-lateral angles of the metasteruum. It 

 differs as follows :— Antenual supports separated by a moderately 

 broad channel, so as not to form an almost continuous ridge 

 between the antenna?. Brothorax distinctly longer than broad, 

 the sides scarcely rounded and not at all tuberculate, the disc 

 rugose-punctate.* Elytra somewhat depressed along the middle, 

 truncate at the apex. lutercoxal process of prosternum less 

 dilated posteriorly, not meeting the epimera.

Testaceous red ; antennae, legs and sides of breast black ; glossy 



above as well as beneath. Head slightly rugose above between the 



eyes, marked in front with oblique impressious which enclose a 



small triangular area. Antennae much longer than the body in 



the c? , a little longer than it in the § ; third, fourth and fifth 



ioints with a distinct posterior spine at the apex, third canaliculate 



above in the 6 • Brothorax about one-fourth longer than broad, 



a little narrower in front than at the base; the disc slightly 



depressed, rugosely punctured. Elytra densely punctate near 



the base, less densely posteriorly; the surface sparsely setose, 



and clothed with a faint pubescence ; apices somewhat obliquely
