460 ON NEW SPECIES OF PHYTOPHAGOUS COLEOPTERA. [Nov. 28, 
under side and legs testaceous ; the extreme basal margin of the 
elytra black. 
Hab. Rio Janeiro. 
This species is principally distinguished by the narrow black 
base of the elytra, which extends to the shoulders and limits the 
fulvous band anteriorly. The colour of the antenne will further 
assist in the recognition of the insect. 
OEDIONYCHIS PROMINULA, sp. un. (Plate XV. fig. 1.) 
Ovately widened posteriorly, black, the apical two joints of the 
antenne fulvous; thorax impunctate, narrowed anteriorly ; elytra 
finely punctured, pale fulvous, the apical third portion black. 
Length 6 millim. 
Head impunctate, with the exception of a single puncture near 
the eyes, black ; the eyes are very large and prominent ; frontal ele- 
vations strongly raised, rather broad ; antenne long and slender, 
black, the apical two joints fulvous, third joint shorter than the 
fourth ; thorax twice as broad as long, the lateral margins rounded, 
the anterior angles thickened and produced into a small tooth, the 
sides broadly suleate, the sulcus connected at the base with another 
shallow transverse groove extending across the disc and close to 
the basal margin, the rest of the surface impunctate, black, very 
shining; seutellum black; elytra widened towards the middle, 
rather broadly margined, minutely and closely punctured, the 
anterior two-thirds flavous, the rest black; under side and legs 
black; metatarsus short, claw-joint strongly swollen ; prosternum 
deeply longitudinally suleate.
