436 MR. MARTIN JACOBY ON NEW SPECIES [ Nov. 28, 
Head piceous or black, the vertex coarsely punctured, the 
clypeus flavous; antennz black, the third and fourth joints very 
nearly equal; thorax strongly transverse, the sides strongly but 
not broadly flattened, the lateral margins rounded in front, 
anterior angles dentiform, the surface impunctate, flavous, with a 
very obsolete transverse sulcus near the base; scutellum black ; 
elytra finely and closely punctured, bluish black, the discoidal 
flavous stripe of double the width of the similarly coloured 
lateral margins and connected with the latter at the apex; under 
side and legs black; elytral epipleurze with a very narrow inner 
dark margin. 
Hab. Brazil. 
This banded species is more nearly allied to O. figurata Chev. 
than to any other, and may be known by the dark head, antenne, 
and legs, the broad discoidal elytral flavous stripe, which has 
somewhat irregular outlines, and by the inner dark margin of the 
elytral epipleure. ‘The species, if these details be kept in view, 
cannot be mistaken for any of those of which v. Harold has given 
an analytical table (Berlin. ent. Zeitschr. 1881). 
OEDIONYCHIS EXCLAMATIONIS, sp. n. (Plate XV. fig. 3.) 
Testaceous, the intermediate joints of the antenne black; 
thorax impunctate; elytra minutely punctured, two elongate 
spots at the base and a longitudinal stripe at the sides, strongly 
thickened at the upper end, black. 
Length 7 millim. 
Head impunctate; the eyes large, each as wide as the inter- 
vening space; carina short and convex, narrow ; antenne tes- 
taceous, the sixth to the ninth joints blackish, third smaller than 
the fourth joint ; thorax more than twice as broad as long, the 
sides strongly rounded and broadly flattened, the anterior angles 
produced into a small tooth, the surface impunctate; elytra not 
wider at the base than the thorax, with narrow reflexed lateral 
margins, extremely finely and closely punctured, testaceous, the 
base with two black longitudinal short stripes, the sides near the 
margins with another longer narrow black stripe, which ends 
anteriorly rather abruptly in a club or knob directed towards 
the suture; under side and legs testaceous. 
Hab. Brazil. 
I know of only a single specimen of this rather peculiarly 
marked species, the exact locality of which is unknown to me. 
OEDIONYCHIS INTERRUPTO-VITTATA, sp. n. (Plate XV. fig. 6.) 
Testaceous, the head and the intermediate joints of the antenne 
black ; thorax impunctate, the anterior angles mucronate ; elytra 
finely punctured, testaceous, each elytron with two more or less 
interrupted longitudinal black stripes ; the breast black. 
Length 6 millim. 
Of flattened shape; the head impunctate, black, deeply foveolate 
between the eyes, the latter large, their diameter as wide as the
