Head finely jiud sparingly pnnctHred, obscure fidvoiis, tin- clypeus not separated 

 from the faee, auteunae extciidiiis to tlie middle of the elylra, flavons, the last four 

 or five joints blaek, the third joint bnt sliglitly longer than tlie second one ; thorax 

 more than twice as broad as long, widened at the middle, the sides straight, the 

 angles acnte, the surface strongly but remotely punctured, the punctures irresrularly 

 distributed, the colour obscure greenish aeneous ; scutellum broad, subtriauguhir ; 

 elytra obscure fuhous with a slight aeneous gloss, the punctures deep, closely 

 approached, the iuterstices broadly longitudinally costate, especially so near the 

 sides where three of the costae below the shoulders are joined at each end before 

 they reach the base or apex, the sutural and lateral margins more or less dark 

 aeneous ; underside and legs fulvous, tarsi darker ; claws bifid. 



Hab. Knilu. 



From any of the describetl sjiecies (as far as short diagnosis will allow judg- 

 ment) the present one is well distinguished by the strongly CQstate elytra ; there is 

 a very narrow sulcus surrounding the eyes as in tlie ntluT sjiecies. 



Nerissus oniata sp. nov. 



I^hick, the base of the femora fulvous, head and thorax metallic green, closely 

 and strongly punctured, sides of thorax strongly serrate, elytra closely punctured, 

 the interstices rugose, metallic green, a broad sutural 1)and cupreous ; femora with a 

 strong tooth. 



Length 3 to 4 lines. 



Head closely rugose-punctate throughout, green, subopaiiue with a central 

 narrow groove, clypeus not separated from the face, antennae black, the basal joint 

 piceous, the ajiical joints slightly dilated, eyes large ; thorax twice as broad as long, 

 the sides rounded with a row of large teetli, the surface convex, crowded with muud 

 and deep jjuuctures ; scutellum pentagonal, strougly punctured ; elytra broader than 

 the thorax, the shoulders prominent, more finely punctured than the thorax, but 

 more strongly so at the sides, where the interstices are transversely rugose, the disc 

 iu the shape of a broad sutural baud abbreviated before the apex, bright cuj)re(ms, 

 rest of the surface blue or green : intermediate tibiae deej)ly emarginate, femora 

 fulvous at the base with a strong tooth; claws bifid; breast and abdomen black, 

 closely pubescent. 



Hfilj. Kuilu. 



The female insect is larger, the thorax broader and with a more or less distinct 

 fovea at each side. This handsome si)ecies will be easily recognised by the system 

 of its coloration. 



Nerissus griseoscutellatus Karsch. 

 It is jirobable, that this species, described in the Berliner Ent. Zeitsch., 1882, 

 is identical with Cheirldea siibrm/osa Jac, described in the Pror. Zool. Soc. of 1882. 

 The only difference I can see is the absence of the white puliescence which limits the 

 black band of the elytra in the species described by me, and of which Karsch says 

 nothing nor indicates in the figure he gives. Neris.im is, however, I think the more 

 correct place than Cheiridea. The only difference between the two genera seems to 

 be the shaj)e of the thorax which in Cheiridea is described by Haly as " subglobose and 

 subcylindrical" ; the same jyartin Nerissus is more flattened and certainly not sub- 

 ci/lindricfd, but both genera liave tlie lateral margin of the thorax serrate. In the
