620 ME. MAETIN JACOBY ON NEW [Nov. &> 



face impunctate, flavous ; scutellum flavoas ; elytra extremely finely 

 punctured, flavous or obscure fulvous, with an elongate bifurcate 

 black mark, placed on tbe shoulder and near the suture, open at its 

 lower end, and a transverse narrow and slightly curved band near 

 the apex not extending to either margin ; underside and legs pale 

 fulvous. 



Hab. Amazons. 



The strongly thickened palpi, the narrow space between the eyes, 

 long antennae, the comparatively narrow thorax, and the shape 

 of the elytral markings well distinguish this species ; the spot at 

 the base of the elytra consists of two short longitudinal stripes, 

 joined at the base, one of which is placed on the shoulder, the other 

 near the suture, the first of these is slightly longer than the sub- 

 sutural one, but both are rather thick. 



CEdiontchis cnAPUisi, n. sp. 



Testaceous, antennae and legs fulvous, vertex of the head black ; 

 thorax impunctate ; elytra scarcely perceptibly punctured, a trans- 

 verse band at the base and another one below the middle, con- 

 nected with a triangular spot at the apex, bluish black. 



Length 2|-3 lines. 



Head impunctate, blackish at the vertex, the clypeus and labrum 

 flavous ; antennae extending to the middle of the elytra, fulvous, 

 the third joint slightly shorter than the fourth ; thorax with strongly 

 rounded sides, the anterior and posterior margins straight, the 

 lateral margins narrowly thickened, the anterior angles not denti- 

 form and but little produced, the surface impunctate ; scutellum 

 piceous ; elytra nearly impunctate, slightly depressed below the 

 base near the suture, with a narrow flattened margin, the trans- 

 verse bands broad, only divided by a narrow band of the ground- 

 colour, and not extending to the sides but to the suture, the anterior 

 margin of the posterior band obliquely cut near the suture, the 

 posterior margin connected at the suture with a triangular-shaped 

 spot which occupies the apical angle ; legs rather darker than the 

 underside, the femora with en obscure piceous spot at the apex. 



Hab. Amazons. 



From most of the transversely banded species <E. cJiapuisi may 

 be known by the extra triangular-shaped spot at the apex of the 

 elytra, which is connected by a narrow sutural stripe with the 

 posterior band. (E. labiata, Schauf., seems to be a closely allied 

 species, but is said to have a distinctly punctured head and 

 elytra, which is not the case here, both in (E. chapuisi being nearly 

 entirely impunctate ; the elytral bands in (E. labiata are further 

 described as being interrupted at the suture, in the present insect 

 they extend entirely across the latter place. Three specimens 

 contained in my collection show no differences in these respects, 

 but in a fourth the pale narrow space which divides the elytral 

 bands does not quite extend to the suture. Whether another 

 specimen from Bolivia which I possess, and which has the elytral 

 bands more distantly apart, represents the same species, it would
