1902.] OF AMERICAN COLEOPTERA. 197 



tellum ; the disc impunctate, testaceous, very obsoletely trans- 

 versely sulcate near the base ; scutellum black, margined with 

 testaceous ; elytra rather broadly ovate, impunctate, with a broad 

 sutural and a very narrow sublateral black band, the disc with 

 another broad band not quite extending to the apex, their epi- 

 pleurse testaceous, black at their inner portion near the base ; 

 below and the legs testaceous, the tibise and tarsi blackish. 



Rah. Peru. 



Shorter and broader than Disonycha elongata, the sutural band 

 much wider and the antennae and legs differently coloured ; the 

 thorax is also more transverse in shape and the posterior angles 

 less obliquely cut ; the elytral pattern resembles entirely that of 

 many species of Disonycha, but the eyes are distinctly reniform 

 and the thorax is of different shape. 



Nephrica itigropasciata, sp. n. 



Black, the apical joints of the antennae and the legs flavous ; 

 thorax impunctate, flavous ; elytra very closely and distinctly 

 punctured, black, a subsutural and a sublateral narrow band, 

 connected at the apex, flavous, apex of the posterior femora black. 



Length 8 millim. 



Head black, shining, impunctate, with the exception of a few 

 punctures near the eyes, the latter very large, reniform ; antennae 

 with the basal and the last four joints flavous, the others black ; 

 thorax twice as broad as long, the sides straight, the angles 

 obliquely truncate, the surface flavous, impunctate ; elytra closely, 

 strongly, and irregularly punctured, flavous, the sutural and 

 lateral mai'gins narrowly black, the disc occupied by a broad 

 longitudinal band which does not extend to the apex ; below 

 black, the femora and tibiae flavous, the apex of the posterior 

 femora and all the tarsi black. 



Hah. Espirito Santo, Brazil. 



A large species, easy of recognition on account of the colour of 

 the antennae and strong elytral punctuation, and resembling much 

 a species of Disonycha, from which the shape of the eyes will 

 distinguish it ; the basal margin of the thorax is scarcely oblique 

 at the posterior angles and altogether different in shape than in 

 Disonycha. 



Nephrica unifasciata, sp. n. (Plate XX. fig. 7.) 



Black, the thorax fulvous, impunctate, obsoletely sulcate ; 

 elytra black, shining and impunctate, a round spot at the base 

 of each and a transverse band near the apex white ; abdomen 

 fulvous. 



Length 6 millim. 



Head black, with a single deep puncture near the eyes, the 

 latter large, reniform, frontal tubercles obsolete, carina strongly 

 raised ; antennae black, the second and third joints small, 

 nearly equal, the fourth elongate ; thorax scarcely twice as broad
