1905.] OF PHYTOPHAGOUS COLEOPTERA. 451 



impunctate, flavous ; scutellum black ; elytra shining, black or 

 nearly so, impunctate, the extreme lateral margins and epipleura:' 

 and the a.pex more broadly flavovis ; femora flavous ; the under side, 

 tibia? and tarsi piceous, the apex of the posterior femora black. 



Hah. Espirito Santo, Brazil. 



A rather small species, not difficult to distinguish, of which I 

 possess two specimens. 



Oedionychis semifoveolata, sp. n. (Plate XY. fig. 5.) 



Black, the thorax and abdomen flavous ; elytra dark j^uiplish, 

 the disc with longitudinal rows of elongate fovea?, the sides 

 nari-owly and the apex broadly flavous, . 



Length 9 millim. 



Head black, impunctate, frontal elevations rather broad ; 

 carina acute, black, clypeus flavous at the sides ; antennse 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 antei'ior angles 

 produced into a tooth, the surface convex, impvinctate ; scutellum. 

 black ; elyti-a dark metallic pin-plish, 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 rovmd greenish foveee, which are placed in rows, 

 interstices entirely impunctate ; under side and legs black, abdomen 

 flavous. 



Hab. Venezuela. 



Closely allied to 0. porosa Baly, but the elytra of difierent 

 sculpture, the fovea? isolated and placed in rows, and the abdomen 

 flavous. A single specimen is contained in my collection. 



In Duvivier's Catalogue 0. porosa Baly is given as a synonym 

 of 0. variolosa Harold, but this requires confirmation, since the 

 size of Baly's species is from 31-4 millim., while Harold gives 

 1 1 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 

 Sia'iii as stated in Duvivier's Catalogue, 1885. 



Oedionychis cub an a Harold. 



Ooleopter. 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 punctvired, black, the lateral margins 

 narrowly and the apex more broadly flavous. 



Length 6-7 millim.
