GEIVA. PSEUDODER A . 



243 



slightly stained with piceous ; elytra metallic-blue; scutellum 

 black. 



Head with vertex impunctate, frontal tubercles small, inter- 

 antennal carina raised. Antennae rather short, extending to the 

 base of the elytra only ; third segment somewhat longer than 

 second and almost equal to fourth, fifth slightly longer than fourth ; 

 the six terminal segments thickened and pubescent. Prothorax 

 about one-half a millimetre broader than long, very convex ; sides 

 straight at the base, rounded in front, base with a very shallow 

 transverse depression, bounded at either side by a deep, perpen- 

 dicularly impressed, line; basal portion deeply but not closely 

 punctate, middle of the upper surface with a broad longitudinal 

 band of strong punctures, which does not reach the front margin. 

 Scutellum broadly triangular, small. Elytra rather strongly 

 punctate-striate, the rows somewhat irregular and closely placed 

 near the suture, more regulnrly so at the sides, where a tendency 

 to form double rows (like those found in the genus Pseudodera) 

 can be recognised ; intervals confusedly punctate. Underside 

 sparsely covered with fine hairs, more thickly so on the abdominal 

 stern ites. 



Length, 6 mm. 



Bengal: Mandar. 



Type in the British Museum. 



Genus PSEUDODERA, Baly. 



Pseudodera, Baly, Journ. of Entomology, i, 1862, p. 200. 



Genotype, Pseudodera xanthospila, Baly (Northern China). 



Body elongate, parallel-sided. Head narrower than prothorax, 

 more or less constricted in front, with the mouth-parts exserted. 

 Antennas nearly as long as the body, with all the segments of almost 

 the same thickness, the third being double the length of the 

 second; interantennal elevations pronounced, with a deep im- 

 pression between them. Eyes comparatively small, situated each 

 on an elevated area. Prothorax broader than long, anterior margin 

 almost straight, with the angles acute, posterior margin also 

 almost straight, with the angles almost right angles, lateral 

 margins rounded ; surface convex, but in front of the basal 

 margin is a transverse impression, which varies in length and 

 depth, but is relatively deep ; on each side of this impression is a 

 short longitudinal impressed line, which also varies in like manner. 

 Scutellum broadly triangular, with apex rounded. Elytra much 

 broader at base than prothorax ; surface smooth and flat, with 

 eleven longitudinal rows of punctures, comprising a short scutellar 

 row, a single sutural row followed by four pairs and an extreme 

 marginal row. Underside-, anterior coxa] cavities closed behind ; 

 posterior femora moderately incrassate ; all the tibiae more or less 

 cylindrical, without channels or spurs ; tarsi with first segment
