422 MR. MARTIN JACOBY ON NEW SPECIES [Nov. 28, 



OeBIONYCHIS APICICORNIS, Sp. 11. 



Elongate, nearly parallel, testaceous ; antennse black, the biisal 

 joint testaceous, the apical one fulvous ; thorax impunctate, the 

 sides rounded, the anterior angles scarcely mucronate ; elytra 

 extremely minutely punctured. 



Length 5 millim. 



Head impunctate, the eyes very large, frontal elevations broad, 

 not strongly raised ; clypeiis deeply defiexed, not prominent ; 

 antennae not quite extending to the middle of the elyti'a, black, 

 the basal joint testaceous, the last one fulvous, third joint shorter 

 than the fourth ; thorax twice as broad as long, of even width, 

 the lateral margins moderately strongly rounded, the anterior 

 angles scarcely produced or mucronate, the sides deeply sulcate, 

 the surface impunctate ; scutellum testaceous ; elytra slightly 

 widened towards the middle, narrowly margined, extremely 

 minutely and closely punctured ; metatarsus short ; claw- joint 

 strongly swollen. 



Hah. Bolivia. 



Closely allied to 0. jxiUescens but larger and the antennte and 

 legs of difierent coloration. 0. paupera Illig. is described as 

 being only 3 millim. in length and with an elongate first joint of 

 the posterior tarsi, which show that the species is an Asphcera. 



Oedionychis sordida, sp. n. 



Black, the head strongly punctured ; thorax fla.vous, with 

 rounded sides and mucronate anterior angles, impunctate ; elytra 

 finely punctured, flavous, the basal portion obscure fulvous ; 

 scutellum black. 



Length 7| millim. 



Broadly elongate, nearly parallel ; the head bluish black, strongly 

 and closely punctured, deeply transversely depressed between the 

 eyes, the latter widely separated ; antennse rather short, bla,ck, 

 the lower three joints shining, the rest pubescent, basal joint short 

 and thick, third and fourth joints subequal, the last of wider 

 shape, the following joints rather robust, cylindrical, slightly 

 shorter ; thorax twice as broad as long, of equal width, the sides 

 deeply sulcate, the lateral margins rounded, the anterior margin 

 produced outwards in shape of a small tooth, the surface flavous, 

 impunctate ; scutellum black ; elytra slightly wider at the base 

 than the thorax, with narrow reflexed margins, nearly parallel, 

 finely but distinctly and very closely punctured ; under side and 

 legs black ; prosternuin longitudinally carinate. 



Hah. Santa Catharina-, Bi-azil. 



There are two specimens of this insect before me, which, 

 although they show some differences, I must refer to the same 

 species. In one the head has only a few punctures and the 

 extreme basal margin of the elytra is stained with black, the 

 colour of the elytra is also entirely pale fulvous ; but in structure 

 the tAvo specimens agree entirely. The species is closely allied to
