1902.] OF AMERICAN COLEOPTERA. 191 



distinct, eyes oblong ; antennae extending beyond the middle of 

 the elytra, black, the basal joint fulvous, the third and following 

 two joints elongate, equal ; thorax strongly transverse, slightly 

 narrowed anteriorly and at the base, the sides rounded anteriorly, 

 with a very narrow margin, the surface impunctate, light fulvous ; 

 scutellum of similar colour ; elytra very distinctly, closely, and 

 somewhat rugosely punctured, with some very obsolete longi- 

 tudinal sulci, dark violaceous blue ; below and the legs pale 

 fulvous, the tarsi infviscate. 



Hah. Brazil. 



Of this species I know only a single specimen, which is in my 

 collection. It is allied to C violaceipennis Clark, but the elytra 

 are without the fiavous lateral margins, the tibiaj are fulvous, not 

 black, and the antennae have the basal joint fulvous only. 



OCNOSCELIS BOLIVIANA, sp. n. 



Testaceous ; antennee greenish black ; head and thorax greenish 

 or fulvous, nearly impunctate ; elytra closely and distinctly 

 punctured, testaceous or obscure fulvous, the base broadly and the 

 sides narrowly metallic green. 



Length 5 millim. 



Male. Of ovate and depressed shape, the head strongly punctured 

 at the vertex, more or less metallic greenish, the frontal tubercles 

 very strongly developed, pyi'iform ; antennae as long as the body, 

 blackish, the basal joint strongly thickened, the third and fourth 

 equal, terminal joints very elongate and slender ; thorax com- 

 paratively long, scarcely one-half broader than long, the sides but 

 feebly rounded, with a narrow flattened margin, the posterior 

 angles acute, the anterior angles obsoletely thickened, the disc 

 nearly impunctate and smooth, more or less metallic green, with 

 the sides narrowly fulvous or entirely of the latter colour ; 

 scutellum blackish ; elytra closely and rather strongly punctra-ed, 

 obscure fulvous, the base more or less metallic green, this colour 

 also extending down at the sides to abovit the middle of the 

 elytra ; below and the legs testaceous, the tibife and tarsi gene- 

 rally darker, the intermediate tibiae of the male strongly curved. 



Hah. Bolivia. 



Like the other three species of this genus, the present one 

 seems rather variable in regard to coloration, but in seven 

 specimens before me the colour of the elytra is constant. The 

 shape of the thoi-ax and the impunctate disc of the latter distin- 

 guish the species from its allies. In the female the antennae 

 are shorter, the thorax is more transverse and is finely punctured. 



Nephrica Harold. 



This genus has been established by von Harold on a species 

 having the general appearance of a Disonycha or Asphcera, but in 

 which the eyes are reniform and emarginate, the sides of the 

 thorax with a narrow margin, and the tibiae without any emargi-
