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. 
Hab. Ceylon. 
657. Dermorhytis lewisi, Juc. P. Z. 8. 1887, p. 82. 
Greenish or brownish-cupreous ; labrum, basal joints of antennae 
and legs obscure fulvous. 
Head closely rugose-punctate ; clypeus not separated from the 
face ; apical joints of antennas 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. 
Hab. Ceylon : Dikoya. 
Distinguished by the straight sides of the thorax and the trans- 
versely rugose interstices. 
658. Dermorhytis cuprea, Jac. P. Z. 8. 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 ; antennse and legs fulvous. 
Length 6-7 mm. 
Hab. Ceylon. 
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
