460 Mr. M. Jacoby on 



Hah. Venezuela. 



Easily distinguished from all its allies by its system of 

 coloration ; the specimen before me seems to be a 

 female. 



LamprosphiBr'US fulvimanus, sp. n. 



Very convex, metallic green below, above cupreous, the basal 

 joints of the antennae and the tarsi fulvous, thorax obsoletely and 

 siDaringly punctured, elytra closely and finely punctate-striate. 



Length 6 niillim. 



Fern. Head finely and rather closely punctured, metallic green, 

 longitudinally grooved at tlie middle, clypeus broad, sparingly 

 punctured, separated from the face by triangular grooves, labrum 

 obscure jDiceous, palpi fulvous, antenna; slender, black, the lower 

 three or five joints more or less fulvous, the third and following 

 joints of nearly equal length ; thorax tliree times broader than long, 

 the sides feebly rounded and obliquely narrowed in front, the 

 posterior margin broadly produced at the middle, the disc finely, 

 irregularly, but not very closely, punctured, the punctures intermixed 

 with larger ones, esjjecially at the sides, the extreme lateral margins 

 metallic green ; scutellum impunctate ; elytra more strongly punctured 

 than the thorax, the punctures arranged in closely approached rather 

 irregular rows, the shoulders prominent, with an obsolete depression 

 immediately below ; below and the legs bright metallic green, 

 impunctate, the tarsi light fulvous ; prosternura broad, about one- 

 half longer than wide, elytral epipleurte flat. 



Hab. Amazons ; also Surinam. 



Larger than L. fidvitarsis, Baly, of different coloration, 

 the thorax not granulate, and differently sculptured, the 

 elytra not excavated near the scutellum. L. igiicipcnnis, 

 Jac, also from the Amazons, is smaller and has differ- 

 ently coloured legs and underside ; the three specimens 

 before me all seem to belong to the female sex. 



Lain])rosp]iairus dimidiatus, sp. n. 



Metallic bluish below, the basal joints of the antennae fulvous, 

 thorax closely punctured, elytra strongly punctate-striate, the inter- 

 stices plane, bluish black, the base with a transverse, laterally 

 widened, broad, fulvous Ijand.

Fern. (?) Of oblong shape, the head metallic greenish, strongly 

 Imt not closely punctured, with a central longitudinal groove, clypeus
