The short antennae, their colour, absence of a thoracic sulcus, 

 and the fine shallow punctures of the elytra separate this species 

 from G. pallipes and several others of similar coloration. 



Genus CRYPTOCEPHALUS. 



Cryptooephalus, Geqffr. Ins. Par. i, 1762, p. 231 ; Suffr. Linn. Ent. 

 ii, 1847, p. 13 ; Chapuis, Gen. Coteopt. 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 subcylindrical 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-aeneous ; labrum, 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 

 subcylindrical, 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. 



Hab. Malabar Coast : Mahe ; Jsilgiris. 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 ; antennae, breast and 

 legs black ; elytra bluish-black, with broad sutural band extending 

 to shoulders but not to apex, sides dark flavous; abdomen 

 flavous.
