442 MR. MARTIN JACOBY ON NEW SPECIES [ Nov. 28, 
distinguished. M. Clavareau, of Brussels, has sent me specimens 
obtained in the Province Huallaga, Peru, which again differ in 
having the elytral band of a golden coppery tint and fulvous head 
and antenne. I am, however, unable to see anything more in 
these differences than one of colour. 
OEDIONYCHIS IMPERIALIS, sp. 0. 
Pale piceous below, the head, antenne, and thorax pale fulvous ; 
elytra very closely and finely punctured, purplish-violaceous, the 
lateral and apical margins and a narrow transverse band at the 
middle flavous. 
Length 9 millim. 
Head flavous, impunctate; the frontal elevations broad, con- 
tiguous; clypeus strongly raised into a triangular ridge, the 
anterior edge of which is very prominent; antenne pale fulvous, 
the third joint one-half shorter than the fourth (the terminal 
two joints wanting); thorax more than twice as broad as long, 
the lateral margins strongly rounded anteriorly, the anterior 
angles thickened but not dentiform, the sides broadly flattened, 
the surface minutely and rather closely punctured, pale flavous ; 
scutellum obscure fulvous; elytra widened towards the middle, 
convex, with narrow reflexed lateral margins, the shoulders 
prominent, the surface extremely closely and finely punctured 
throughout, purplish violaceous, a narrow straight transverse 
band at the middle and the lateral and apical margins (the latter 
slightly more widely so) flavous; under side and legs pale piceous. 
Hab. Yurimaguas, Peru. 
This species differs from O. steinheili Jac. (Proc. Zool. Soc. 1880, 
p- 179) in the pale-coloured antennze, in the differently shaped 
anterior angles of the thorax, and in the narrow and straight, 
flavous band of the elytra; the larger size and colour of the 
elytra separate the species from other nearly similarly marked 
species, as well as from O. bifasciata Baly, which has also differently 
coloured antenne and a black apex to the posterior femora. 
OEDIONYCHIS OCCIPITALIS, Sp. n. 
Testaceous, the base of the head and the terminal joints of the 
antenne black; thorax impunctate; elytra microscopically punc- 
tured, testaceous, a transverse band at the base connected at the 
suture with another broad band below the middle, black; the breast, 
abdomen, and the posterior tibize more or less piceous or black. 
Var. a. The elytral bands not connected at the suture. 
Var. b. Elytra with a spot near the scutellum and an elongate 
larger spot below the middle, black. 
Var. c. Elytra entirely testaceous. 
Length 4—5 millim. 
Head impunctate, black at the vertex, the lower portion 
testaceous, frontal elevations broad, eyes large; antenne slender, 
the lower four or five joints testaceous, the others piceous, third
