420 MR. MARTIN JACOBY ON NEW SPECIES [ Nov. 28, 
Hab. Pavaguay. 
Of this species, very well distinguished by the almost rugose 
entire upper surface, I know of only a single specimen. 
OEDIONYCHIS NIGROSUTURALIS, Sp. 1. 
Black ; thorax finely and sparingly punctured, testaceous ; 
elytra strongly convex, closely and strongly punctured, testaceous, 
the extreme sutural margins black; abdomen fulvous. 
Length 9 millim. 
Head entirely black, with a few punctures near the eyes; 
clypeus strongly convex between the antenne, the latter short, 
not extending to the middle of the elytra, black, the lower two 
joints obscurely stained with piceous, third joint distinctly shorter 
than the fourth; thorax rather more than twice as broad as long, 
the lateral margins strongly rounded, anterior angles not produced 
but thickened, sides deeply but narrowly sulcate, the disc very 
sparingly and finely punctured, testaceous; scutellum black ; 
elytra rather strongly convex below the middle (when viewed 
sideways), with very narrow, thickened, reflexed margins, very 
closely and comparatively strongly punctured, the suture very 
narrowly black; breast and legs black ; abdomen fulvous. 
Hab. Braaal. 
T know of only a single, apparently female specimen of this 
species, which is distinguished by the strongly punctured, convex 
elytra and black suture, as well as by the colour of the head and 
under side. 
OEDIONYCHIS PICIFRONS, sp. n. (Clark Catal.). 
Testaceous, the vertex of the head and the antenne pale 
piceous ; thorax impunctate; elytra very finely and closely 
punctured ; posterior femora pale fulvous. 
Length 6} millim. 
Of somewhat flattened, oblong shape, the head impunctate, the 
vertex very pale piceous, frontal elevations strongly raised, 
trigonate ; clypeus triangularly carinate; eyes large, widely 
separated ; antenne extending to the middle of the elytra, pale 
piceous, third and fourth joints equal; thorax with the sides 
rather strongly rounded and broadly flattened, the anterior 
angles thickened but only slightly produced, the surface im- 
punctate ; scutellum pale piceous ; elytra slightly widened 
towards the middle, narrowly margined, extremely finely and 
rather closely punctured, the shoulders very prominent and deeply 
longitudinally suleate within, the depressions more strongly 
punctured, pale testaceous ; under side and legs coloured like the 
upper surface, the posterior femora pale fulvous or piceous. 
Hab. Brazil. 
Of more oblong shape, less broadly rounded than most of the 
unicolorous species, very pale testaceous, with the exception of the 
head, antennz, and the posterior femora; the sides of the thorax 
rather strongly rounded, the shoulders very prominent.
