Hal). Humboldt l?ay (New (juinea). 



This species seems very distinct from C. semipunddta, subpolita, and impressa, 

 the underside is entirely black and has no yellow pubescence arranged in jiatcbes, 

 but is uniformly and thinly covered with grey hairs, the thorax is peculiarly con- 

 structed on account of the raised anterior space, and the elyti'al punctuation is entirely 

 obliterated at the sides and below the middle, the antennae have the joints also more 

 elongate than in the allied spei-ies. C. ohlitevata Baly has similarly punctured elytra, 

 but the antennae have differently proportionate joints, the thorax is of different 

 structure, and the general coloration is distinct from the present species. 



Crioceris divisa sp. nov. 



Fulvous, antennae obscure fuscous ; thorax subquadrate, impunctate, elvtra with 

 a few punctures near the suture, rufous, a transverse band at the base and a round 

 spot near the apex black. 



Length 4 lines. 



Head deejily constricted behind the eyes, the latter very prominent, deeply 

 notched, supra-ooular grooves very deep, antennae extending a little beyond the base 

 of the elytra, the basal four joints fulvous, shining, tlie third and fourth etjual, 

 slightly longer than the second, the following joints pubescent, elongate, stained with 

 fuscous above ; thorax not longer than broad, the sides moderately deeply constricted, 

 the surface not very convex without basal sulcus, impunctate, with the exception of 

 a single row of fine punctm-es at the middle of the disc ; scutellum fulvous ; elytra 

 with the base slightly raised near the suture, the surface entirely impunctate, with 

 the exception of three short rows of punctures near the suture, the row nearest the 

 latter continued in shape of a stria towards the apex, the lateral margin thickened, 

 the ferruginous colour of the disc is interrupted at the base by a transverse bluish 

 black band, extending to one-third the length of the elytra, another roundish spot is 

 ])laced near the apex ; undersiile and legs nearlv glabrous, fuK'ous ; mesosternum 

 truncate in front.

Melixanthus rothschildi sji. nov. 



Fulvous, the antennae (the basal joint excepted), the ajjex of the femora, and 

 the tibiae and tarsi black ; thorax impunctate, elytra finely punctate-striate.

 the elytra, black, the basal joint fulvous, the second small, the third twice as long, 

 the fifth and following joints flattened and dilated ; thorax very convex and cylindrical,
