428 MR. MARTIN JACOBY ON NEAV SPECIES [Nov. 28, 



the bi'east piceous ; thorax impunctate ; elytra subdepressed, 

 extremely closely and finely punctured, the basal margin, a narrow 

 transverse band below the middle, and two spots near the scutellum 

 dark brown. 



Length 7 millim. 



Head impunctate, testaceous, the frontal elevations rather 

 feeble ; eyes large, the intermediate space not wider than the width 

 of each eye ; antennge with the basal three or four joints and the 

 apical one testaceous, the rest blackish ; thorax short and trans- 

 verse, the sides broadly flattened, the anterior angles dentiform ; 

 the disc impunctate, testaceous, feebly transversely sulcate near 

 the base ; scutellum testaceous ; elytra widened towards the apex, 

 rather flat, extremely finely and closely punctured, testaceous, the 

 extreme basal margin, a small spot near the scutellum, and a 

 narrow transverse, slightly convex band, immediately below the 

 middle, piceous or dark fulvous ; legs testaceous ; breast and 

 abdomen piceous. 



Hah. Pichinche, Colombia (Bosenberg). 



Of this species I have five exactly similar specimens before me. 

 The design of the elytra difiers from that of any other species 

 I am acquainted with except 0. tenuicincta Jac, which is a dif- 

 ferently shaped insect, with a difierent thorax, very nai'row elytra! 

 bands, and of black colour. This species is also known from Mexico. 



Oedionychis diversa, sp. n. 



Testaceous, the apical joints of the antennae (except the last) 

 and the breast black ; thorax impunctate ; elytra elongate, finely 

 punctured, each with two spots at the base, one at the middle, and 

 a transverse band near the apex, black. 



Var. The apical band divided into two spots. 



Length 5 millim. 



Head impunctate, deeply foveolate between the eyes, the latter 

 very large ; antennae with the lower five and the apical joint testa- 

 ceous, the others black, third and fourth joints equal, elongate, 

 the terminal joints rather shorter ; thorax about twice and a half 

 broader than long, the sides broadly flattened, the lateral margins 

 strongly rounded anteriorly, the anterior angles thickened but 

 not produced, the surface impunctate, rather convex ; scutellum 

 black ; elyti'a elongate, nearly parallel, very minutely punctuied, 

 testaceous, a small spot on the shoulders, another near the scutellum, 

 a third at the middle, and a transverse band near the apex, not 

 quite extending to either margin, black ; legs and abdomen testa- 

 ceous, breast black. 



Ilab. St. Catharina, Rio Janeiro, Brazil. 



A somewhat elongate species, principally distinguished from 

 those with similar elytral spots by the additional black subapical 

 band and the black breast, colour of the antennae, &c. 



Oedionychis bisbinotata, sp. n. (Plate XV. fig. 8.) 



Flavous, the apical joints of the antennae black ; thorax im-
