434 MR. MARTIN JACOBY ON NEW SPECIES [Nov. 28, 
short and transverse, the sides rounded and broadly flattened, the 
anterior angles acute but not dentiform, the surface entirely 
impunctate, testaceous; scutellum piceous; elytra with broadly 
flattened margins, slightly widened at the middle, finely and closely 
punctured, testaceous, with two broad fulvous transverse bands— 
one at the base, deeply concave at its lower margin and connected 
by a sutural stripe with the second band near the apex of obliquely 
subquadrate shape, both bands are interrupted at some distance 
from the lateral margins and are more or less distinctly edged 
with piceous, the basal margin especially so; under side and legs 
testaceous. 
Hab. Argentine R. and Brazil. 
Not unlike O. pustulata Jac. in coloration, but the antennz 
differently coloured, the thorax without a fulvous spot, and the 
elytral bands of different shape. 
OEDIONYCHIS CATHARINA, Sp. n. 
Dark fulvous below, antenne black; thorax flavous, impunctate ; 
head and scutellum dark fulvous; elytra rather strongly and 
closely punctured, dark fulvous, a large discoidal ovate patch on 
each, flavous. 
Length 6 millim. 
Of rather elongate and parallel shape; the head impunctate, 
fulvous, deeply grooved between the eyes, the latter large, frontal 
elevations broad, transverse; carina blunt and thick; antenne 
robust, black, third joint distinctly shorter than the fourth; thorax 
strongly transverse, the lateral margins distinctly rounded, the 
anterior angles but slightly produced outwards, scarcely toothed, 
lateral sulci broad and deep, the surface impunctate, flavous; 
elytra with narrow reflexed margins, fulvous, distinctly punctured, 
the dise occupied by a large flavous ovate patch, with its nar- 
rowest portion near the suture ; under side and legs dark fulvous, 
the tibize and tarsi blackish ; metatarsus very short, claw-joint 
strongly inflated. 
Hab. St. Catharina, Brazil. 
Of somewhat similar coloration to O. 4-pustulata Jac. from the 
same locality, but the thorax without fulvous spot, the antennz 
entirely black, with more elongate joints, and the whole apex of 
the elytra fulvous; the thoracic sulci in the present species also 
are wider and deeper. 
OEDIONYCHIS OCELLATA, sp.n. (Plate XV. fig. 10.) 
Black, thorax testaceous, with three black spots; elytra closely 
and strongly punctured, each elytron with six small flavous 
spots (1.2.2.1). 
Length 5 millim. 
Head not perceptibly punctured, the middle black, the sides and 
the anterior portion testaceous, frontal tubercles short and broad, 
strongly raised, carina broad; antenne rather short and robust, 
black, the lower three joints more or less flavous, third joint more
