1905. | OF PHYTOPHAGOUS COLEOPTERA. 451 
impunctate, flavous; scutellum black; elytra shining, black or 
nearly so, impunctate, the extreme lateral margins and epipleurse 
and the apex more broadly flavous ; femora flavous ; the under side, 
tibiz and tarsi piceous, the apex of the posterior femora black. 
Hab. Espirito Santo, Brazil. 
A rather small species, not difficult to distinguish, of which I 
possess two specimens. 
OEDIONYCHIS SEMIFOVEOLATA, sp. n. (Plate XV. fig. 5.) 
Black, the thorax and abdomen flavous ; elytra dark purplish, 
the dise with longitudinal rows of elongate fovee, the sides 
narrowly and the apex broadly flavous. 
Length 9 millim. 
Head black, impunctate, frontal elevations rather broad ; 
carina acute, black, clypeus flavous at the sides; antenne black, 
the basal joint flavous below, third joint shorter than the fourth ; 
thorax more than twice as broad as long, narrowed anteriorly, the 
sides rounded, with a broad, flattened margin, the anterior angles 
produced into a tooth, the surface convex, 1mpunctate; scutellum 
black ; elytra dark metallic purplish, margined at the sides and 
apex with flavous, at the first named place narrowly so, at the 
latter suddenly widened into a broad band the anterior edge of 
which is quite straight, the disc impressed with distant, elongate 
and partly round greenish fovee, which are placed in rows, 
interstices entirely impunctate; under side and legs black, abdomen 
flavous. 
Hab. Venezuela. 
Closely allied to O. porosa Baly, but the elytra of different 
sculpture, the fovez isolated and placed in rows, and the abdomen 
flavous. A single specimen is contained in my collection. 
Jn Duvivier’s Catalogue O. porosa Baly is given as a synonym 
of O. variolosa Harold, but this requires confirmation, since the 
size of Baly’s species is from 33-4 millim., while Harold gives 
11 millim as the length; Duvivier, moreover, has only given a 
short diagnosis, which in these closely allied and numerous groups 
of insects is quite useless. 
OEDIONYCHIS PRETIOSA Baly. 
The locality of this species as given by the author is Brazil, not 
Siam as stated in Duvivier’s Catalogue, 1885. 
OEDIONYCHIS CUBANA Harold. 
Coleopter. Hefte, xiii. p. 90: Cuba. 
This species is not mentioned in any of the Catalogues. 
OEDIONYCHIS FLAVOMARGINATA, sp. n. (Plate XV. fig. 9.) 
Black, thorax impunctate, the sides broadly flavous ; elytra 
convex, finely and closely punctured, black, the lateral margins 
narrowly and the apex more broadly flavous. 
Length 6-7 millim.
