1905. | OF PHYTOPHAGOUS COLEOPTERA. 437 
dividing space; labrum fulvous; antennz with the lower four and 
the apical three joints fulvous, the others black, third and follow- 
ing joints nearly equal, elongate; thorax with strongly rounded 
and flattened sides, the anterior angles mucronate and produced 
forward, the dise impunctate, testaceous, obsoletely transversely 
grooved near the base ; elytra finely and closely punctured, rather 
flattened, narrowly marginate, each elytron with two narrow 
longitudinal stripes—one near the suture, the other near the 
lateral margins, below the middle beth, or one, of the stripes are 
interrupted, so that only one or two elongate spots remain near 
the apex ; under side and legs testaceous, the breast black. 
Hab. St. Catharina, Brazil. 
In one of the specimens the inner black elytral stripe only is 
interrupted ; in the other this is the case with both stripes, there 
is also an indication of another stripe in shape of a minute spot 
between the others, placed at the middle. Amongst the species 
with elytral longitudinal bands the present one is well distin- 
guished by the colour of the head, antennz, and the shape of the 
elytral stripes, which resemble signs of exclamation. 
Elytra pale, with transverse black or blue bands or spots. 
OEDIONYCHIS BISTRIFASCIATA, Sp. 0. 
Black or piceous, antenne dark fulvous, clypeus flavous ; thorax 
impunctate, flavous; elytra finely and closely punctured, flavous, 
each with three transverse dark blue bands, the first subquadrate 
and emarginate or subdivided at the base. 
Length 53 millim. 
Of rather elongate shape; the head bluish black, with some 
strong punctures near the eyes; clypeus and labrum flavous, the 
eyes likewise margined more or less with the same colour ; antennz 
extending to nearly the middle of the elytra, dark fulvous, the 
basal two joints more or less stained with black above, third and 
fourth joints equal, terminal joints slightly thickened; thorax 
rather more than twice as broad as long, the sides strongly but 
not very broadly flattened, the lateral margins rounded anteriorly, 
anterior angles produced into a short blunt tooth, the surface 
impunctate or with a few very minute punctures, obsoletely 
transversely grooved near the base, flavous; scutellum black ; 
elytra finely and closely but distinctly punctured, with three 
transverse blue or purplish bands—the first at the base the largest, 
of subquadrate shape, its basal margin with a narrow incision, 
the second band immediately below the middle, half the width of 
the first band, the third near the apex, short and of subquadrate 
shape, none of these bands extends to either margin; below and 
the legs black or piceous. 
Hab. Peru. 
In one of the specimens before me the basal band is also rather 
deeply emarginate near the suture at the sides as well as at the 
base.
