440 MK. MARTIX JACOBY ON NEW SPECIES [NoV. 28, 



transverse ; antennae long and slender, black, the lower tliree 

 joints more or less piceous below, third joint shorter than the 

 fourth, intermediate joints slightly widened ; thorax more than 

 twice as broad as long, the sides strongly rounded and deeply 

 sulcate, anterior angles distinctly produced into a tooth, the disc 

 fulvous, minutely punctured when seen under a very strong lens ; 

 scutellum black, broad ; elytra widened towards the middle, tes- 

 taceous, with three metallic green transverse bands which do not 

 extend to the lateral margins ; of these bands, which are all con- 

 nected with each other at the suture, the first is of somewhat 

 irregular shape and does not extend to a third of the length of 

 the elytra, its posterior edge is irregularly serrate, the second 

 band at the middle is broader (in a longitudinal sense) and of 

 more regular shape, the third band is again narrow and more or 

 less curved and does not extend to the apex, which remains of the 

 ground-colour ; below and the legs black, metatarsus of the pos- 

 terior legs shorter than the following two joints together, claw- 

 joint strongly swollen. 



Rab. Pachitea, Peru. 



A handsome species, distinguished by the three bright metallic 

 green elytral bands. 



Oedionychis illustris, sp. n. (Dej. i. litt.) (Plate XY. fig. 11.) 



Testaceous, the legs dark fulvous ; thorax short, impunctate ; 

 elytra convex, scarcely perceptibly punctured, a broad transverse 

 band at the base, another below the middle, not extending to the 

 suture, and the apex purplish violaceous. 



Length 8 millim. 



Head impunctate, the vertex obscure purplish, the rest of the 

 face testaceous ; clypeus strongly raised in shape of a triangular 

 ridge ; eyes large ; antennse piceous, the basal joint testaceous 

 below, third joint shorter than the fourth ; thorax short and 

 transverse, the sides broadly flattened, the anterior angles pro- 

 duced but scarcely dentiform, the surface impunctate, testaceous ; 

 scutellum black ; elytra widened towards the middle and convex, 

 extremely minutely punctured, flavous, with two transverse 

 broad purplish bands — the first at the base, not quite extending 

 to the middle nor to the lateral margins, the second, in shape of a 

 transversely subquadrate band, not extending to either margin, 

 another triangular spot occupies the apex ; all these bands are 

 separated by nearly equal narrow sj)aces of the flavous ground- 

 colour, but the basal band extends across the suture ; vinder side 

 and the base of the anterior and intermediate femora testaceous, 

 the I'est of the legs and the posterior femora dark fulvous. 



Hab. Cayenne. 



A species of broadly ovate shape and resembling in its markings 

 0. hitmniaia Baly, but in that species the second elytral band 

 extends to the suture, all are of much more narrow shape, and 

 dull blue instead of metallic purple.
