all the joints from the third outwards of equal length. Thorax 

 obsoletely biangulate at the middle, sculptured like the head, 

 interstices irregularly convex and reticulate, the punctures scarcely 

 larger than those on the head. Elytra more remotely and strongly 

 punctured than the thorax, interstices transversely reticulate over 

 the entire surface, the lateral margins as well as those of the 

 thorax narrowly cupreous. 



Length 5-6 mm.

657. Dermorhytis lewisi, Jc. P. Z. S. 1887, p. 82. 



Greenish or brownish-cupreous ; labruni, basal joints of antennas 

 and legs obscure fulvous. 



Head closely rugose-punctate ; clypeus not separated from the 

 face ; apical joints of antennae very slightly thickened, third and 

 fourth joints equal, basal five or six joints fulvous, rest fuscous. 

 Thorax transverse, sides nearly straight, surface closely and 

 strongly punctured, interstices everywhere transversely rugose. 

 Elytra subcylindrical, slightly narrowed posteriorly, punctured like 

 the thorax, but the interstices transversely raised over the entire 

 surface. Body beneath clothed with fine silky pubescence. 



Length 5-6 mm. 



Sab. Ceylon: Dikoya. 



Distinguished by the straight sides of the thorax and the trans- 

 versely rugose interstices. 



658. Dermorhytis cuprea, Jac. P. Z. S. 1887, p. 81. 



Bronze-coloured ; legs nearly black ; antennae piceous ; thorax 

 and elytra with more or less of a greenish-cupreous gloss. 



Head strongly rugosely punctured on the vertex ; clypeus 

 separated from the face, much more finely and closely punc- 

 tured ; antennae two-thirds the length of the body, third and 

 following three joints piceous, equal, the rest nearly black, slightly 

 thickened. Thorax half as broad again as long, sides angulate 

 before the middle, straight from thence to base, anterior 

 portion obliquely narrowed ; surface strongly and moderately 

 closely punctured on the disc, sides more strongly punctate and 

 transversely rugose. Elytra wider at base than the thorax, surface 

 more or less punctate-striate near suture, strongly and irregularly 

 punctured on the sides, the interstices at that place transversely 

 rugose. 



Var. Metallic green ; antenna and legs fulvous. 



Length 6-7 mm.

Since describing this species in 1887 I have seen other speci- 

 mens which, although in colour and puncturation they vary greatly, 

 I refer to the present form. In none of them are the punctures
