CIIltYSOMELIDvE. 
The short antennae, their colour, absence of a thoracic sulcus, 
and the fine shallow punctures of the elytra separate this species 
from C. pallipes and several others of similar coloration. 
Genus CRYPTOCEPHALUS. 
Cryptocephalus, Geoff r. Ins. Par. i, 17G2, p. 231 ; Snffr. Linn. Ent. 
ii, 1847, p. 13 ; Chapuis, Gen. Coleopt. x, 1874, p. 184. 
Type, C. 10-maculatus, Linn., from Europe. 
Range. Nearly all parts of the globe. 
Antennae filiform ; prosternum with posterior margin more or 
less emarginate, the angles acute or strongly pointed. Thorax 
closely fitted to base of elytra, with simple lateral margins. 
This genus contains the bulk of the species of the subfamily. 
The subcylindrieal shape, filiform antennae, neat coloration, flat 
head, deeply inserted in the thorax, and the reniform eyes are 
characters by which these insects can be easily distinguished. 
Entirely or partly metallic species. 
335. Cryptocephalus metallicus, sp. n. 
Metallic dark blue or greenish-asneous ; labrurn, basal joints of 
antennae and legs fulvous ; tarsi black. 
Head finely rugosely punctured with a very faint central groove ; 
clypeus feebly separated from face, its anterior edge straight ; 
eyes angularly emarginate, widely separated ; antennae slender, 
black, basal four joints fulvous, third and fourth equal, fifth and 
following joints more elongate and very slender. Thorax strongly 
transverse, very convex, narrowed anteriorly, sides narrowly 
margined, rather rounded, posterior angles acutely produced, 
preceded by a transverse depression, surface extremely minutely 
punctured, the punctures only seen under a very strong lens. 
Scutellum broad, apex pointed, base with a small fovea. Elytra 
subcylindrieal, narrowed posteriorly, rather finely punctate-striate, 
shoulders prominent and elongate, smooth ; interstices flat, here 
and there with a few minute punctures. Body beneath darker 
greenish-aeneous, finely punctured and pubescent. Legs very stout, 
tarsi black, strongly widened. Prosternum longer than broad, 
longitudinally excavated, posterior angles pointed. 
Length 5| mm. 
Ilab. Malabar Coast : Mahe ; Nilgiris. Type in Coll. Jacoby. 
Easily distinguished by the metallic coloration of the upper and 
under surfaces and the fulvous legs. 
336. Cryptocephalus submetallicus, sp. n. 
Head and thorax metallic dark green ; antennfe, breast and 
legs black ; elytra bluish-black, with broad sutural band extending 
to shoulders but not to apex, sides dark flavous; abdomen 
flavous.
