304 CHEYSOMELID^. 



sides oblique, strongly narrowed in front, angulated close to base ; 

 surface strongly rugosely punctured throughout, anterior sulcus 

 deep. Elytra wider at base than thorax, convex, subquadrate, 

 moderately deeply depressed below base, very closely and strongly 

 punctate-striate ; shoulders prominent, Femora bluish. 



Length 2^ mm. 



Hob. Burma : Bhamo. Type in Genoa Museum. 



The rugosely punctured head and thorax, closely punctured 

 elytra and much smaller size separate this species from the 

 preceding. 



521. Nodostoma cyaneum, Lefev. Bull Soc. Ent. Belg. xxxv, 1891, 



p. cclxvi. 



" Beneath black ; breast obscure cyaneous ; above dark 

 cyaneous ; labrum, palpi and antennae fulvous, apical five joints 

 of antennae and the legs black ; tarsi fuscous. 



"Head strongly punctured, a small fovea between the eyes. 

 Thorax transverse, sulcate near the anterior margin ; sides before 

 the middle subspinosely angulate; surface convex, finely and densely 

 aciculately punctured. Scutellum smooth, foveolate at middle, 

 apex rounded. Elytra below base feebly transversely impressed, 

 punctate-striate, punctures at sides and within depression larger ; 

 humeral callus very prominent, smooth. 



" Length 7 inm. 



Hab. "Sikhim." (Lefevre.} 



A large species, but unknown to me. Lefevre gives the sides 

 of thorax as angulate " before the middle " ; as a rale, the angu- 

 lation is behind the middle. 



522. Nodostoma pretiosum. sp. n. 



Metallic cupreous, blue or green ; basal joints of antennas and base 

 of femora fulvous, terminal joints of antennas and the tarsi black. 



c?. Broadly ovate. Head coarsely rugose-punctate, vertex at 

 middle smooth ; labrum and palpi fulvous ; antennae slender and 

 filiform, basal four joints fulvous. Thorax strongly transverse ; 

 sides angulate behind the middle, strongly obliquely narrowed in 

 front ; anterior sulcus deep ; surface very strongly punctured, on 

 the sides the punctures partly confluent. Elytra subquadrately 

 ovate, distinctly depressed below base at the sides ; puricturation 

 much finer than that of thorax, more strongly punctured within 

 depression, the rows distantly placed, extremely fine at apex. 

 Femora strongly incrassate, knees and tibiae metallic ; femoral 

 tooth minute. Body beneath greenish. 



The female scarcely differs from the male, except in its larger 

 size and more slender antennae. 



Var. Legs entirely metallic blue or green. . 



Length 4^-5 mm. 



Hab. Assam : Sylhet. 



The very strong thoracic puncturation distinguishes this species.
