Type, N. pusilla, Motsch., from India. 



Range. India ; Japan ; Malayan Subregion. 



Body rounded, short and convex ; head deeply inserted ; antennae 

 scarcely extending to half the length of body, terminal joints more 

 or less thickened. Thorax transverse, sides not angulate. Elytra 

 not wider at base than thorax, not depressed below base, surface 

 punctate-striate. Legs rather short and stout; femora unarmed; 

 posterior and intermediate tibiae more or less emarginate near 

 apex ; tarsi equal, rather short; claws appendiculate. Prosternum 

 transverse, subquadrate. 



Small and generally metallic species, distinguished by the nearly 

 equal width of the thorax and elytra at base, and the rather short 

 and thickened joints of the antennae. Both Baly and Lefevre 

 give the antennas as filiform, and describe their length as more 

 than half that of the body ; this is certainly not the case, as 

 Motschulsky, in his description of the type, N. pusilla, describes 

 the terminal joints as dilated. In all species that I have 

 examined these joints extend only up to the base of the elytra, 

 and are certainly not filiform. 



a. Legs fulvous. 



498. Nodina indica, Jac. Ann. Soc. Ent. Belg. xxxix, 1895, p. 271. 



Beneath black, above greenish-aeneous ; antennas and legs fulvous. 



cf . Proportionately elongate and parallel-sided ; head very finely 

 and sparingly punctured, with narrow sulci above the eyes ; 

 mandibles black ; palpi fulvous ; antennae extending to base of 

 thorax only, terminal joints transversely widened. Thorax twice 

 as broad as long, sides evenly rounded, scarcely narrowed in front; 

 surface rather closely and strongly punctured, the punctures 

 evenly distributed, posterior margin oblique at each side, median 

 lobe short and rounded. Elytra strongly punctate-striate an- 

 teriorly, finely so towards apex. 



5 . Head and thorax more strongly and closely punctured ; 

 elytra with three short lateral costae, the outer costa the longest. 



Length 1-2 mm.
