1905. | OF PHYTOPHAGOUS COLEOPTERA. 433 
Head fulvous, impunctate, eyes widely separated; antenne 
black, the basal two joints obscure fulvous, terminal joints 
shortened, third and fourth equal; thorax twice as broad as long, 
the sides rounded anteriorly, the middle of the disc rather convex, 
the anterior angles produced outwards into a small tooth, the sides 
broadly flattened and subrugose, the surface impunctate, obsoletely 
transversely sulcate near the base; scutellum black; elytra not 
perceptibly depressed below the base, dark blue, not very shining, 
closely and distinctly rugose punctate throughout; below and the 
legs bluish black; prosternum comparatively broad, flavous. 
Hab. Petropolis, Brazil. 
A well-distinguished species on account of the colour and 
sculpture of the elytra. 
Llytra dark, with flavous spots, patches, or bands. 
OEDIONYCHIS INTERSIGNATA, sp. n. (Clark Catal.). 
Black, thorax flavous; elytra closely and strongly punctured, 
violaceous or blue, a transverse band or broad patch at the middle, 
the apex and the lateral margins (partly) flavous. 
Length 7 millim. 
Head piceous or black, impunctate, eyes very large, as wide as 
the intraocular space, frontal elevations strongly raised, pyriform, 
carina acute; antenne black, the lower three joints fulvous below, 
third and fourth joints equal; thorax quite twice as broad as long, 
the sides rounded, broadly flattened within, the anterior angles in 
shape of a very small tooth, the surface impunctate, flavous ; 
scutellum black; elytra strongly and closely punctured, blue, 
violaceous or purplish, with a transverse flavous patch at the 
middle and a smaller one at the apex, the lateral margins 
anteriorly and posteriorly likewise flavous as well as the elytral 
epipleure ; underside and legs black. 
Hab. Espirito Santo, Brazil. 
A rather variable species as regards the flavous markings of 
the elytra, but distinguished by the comparatively strong punc- 
tuation; the central flavous band scarcely extends to the suture, 
nor does the apical one, but both unite with the flavous lateral 
margins. 
OEDIONYCHIS RUSTICA, Sp. n. 
Testaceous, the intermediate joints of the antennz black; thorax 
impunctate; elytra extremely closely and finely punctured, a 
transverse band at the base, another of oblique shape near the 
apex, and the intermediate portion of the suture fulvous, more or 
less edged with piceous. 
Length 5 millim. 
Head impunctate, eyes very large and rather closely approached ; 
frontal elevations broad, subquadrate, divided by a narrow groove; 
antenne extending beyond the middle of the elytra, the five lower 
and the terminal two joints fulvous, the others blackish; thorax
