422 MR. MARTIN JACOBY ON NEW SPECIES | Noy. 28, 
OEDIONYCHIS APICICORNIS, Sp. Nh. 
Elongate, nearly parallel, testaceous ; antennz black, the basal 
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; clypeus deeply deflexed, not prominent ; 
antenne not quite extending to the middle of the elytra, 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. 
Hab. Bolivia. 
Closely allied to O. pallescens but larger and the antenne and 
legs of different coloration. O. 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 Asphera. 
OEDIONYCHIS SORDIDA, sp. nh. 
Black, the head strongly punctured; thorax flavous, with 
rounded sides and mucronate anterior angles, impunctate; elytra 
finely punctured, flavous, the basal portion obscure fulvous; 
scutellum black. 
Length 73 millim. 
Broadly elongate, nearly parallel; the head bluish black, strongly 
and closely punctured, deeply transversely depressed between the 
eyes, the latter widely separated ; antenne rather short, black, 
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 suleate, 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 ; prosternum longitudinally carinate. 
Hab. Santa Catharina, Brazil. 
There are two specimens of this insect before me, which, 
although they show some differences, | 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 two specimens agree entirely. The species is closely allied to
