190 MR. MARTIN JACOBY ON NEW SPECIES [Mar. 4, 



regular rows, their epipleurse very broad, continued to the apex ; 

 below flavous, the tibiae and tarsi black (sometimes only infuscate), 

 the posterior tibise with a small spur, the others unarmed ; pro- 

 sternum narrow, anterior cavities open. 



Hah. Espirito Santo, Brazil. 



What I take to be the female of this species differs in having 

 a rather broad reflexed lateral mai^gin to the elytra, and the upper 

 svirface of a more pronounced fulvous ; otherwise there is no 

 difference of any importance. The species differs from G. Jlava 

 Clark and C. testacea 01. in the general smaller size, the arrange- 

 ment of the elytral punctuation, and in the black tibise and tarsi. 

 In the female the elytral interstices are more or less costiform. 

 The species, like several others placed in this genus, has entire, 

 not emarginate tibise. 



Oacoscelis varipes, sp. n. 



Below black ; head and thorax fulvous, impunctate ; elytra 

 dark greenish, opaque, minutely punctured; the anterior and 

 intermediate femora fulvous, the tibise and tarsi and the posterior 

 femora black. 



Length 10 millim. 



Head extremely minutely punctured when seen under a strong 

 lens, fulvous, the frontal elevations subquadrate, rather strongly 

 raised; clypeus with a highly raised blunt ridge between the 

 antennae, the last-named organs black, the basal joint fulvous, the 

 terminal two joints very elongate, much longer than the preceding 

 ones ; thorax nearly twice as broad as long, slightly narrowed 

 anteriorly, the sides feebly rounded, with a rather broad flattened 

 margin, the base with a shallow sulcus, not extending to the 

 sides, the anterior angles slightly thickened, the surface im- 

 punctate, fulvous ; scutellum broad, black ; elytra slightly wider 

 at the base than the thorax, rather convex, of opaque greenish 

 colour, very finely punctured, with a narrow reflexed lateral 

 margin, their epipleurse very broad and concave ; below clothed 

 with grey pubescence, black, the anterior and intermediate femora 

 fulvous ; tibise not emarginate at the apex, the first joint of the 

 posterior tarsi as long as the following joints together. 



Hah. Brazil. 



Of this species, which difiers in coloration from any of its 

 allies, a single specimen is in my collection, without any exact 

 locality. It is somewhat allied in colour to G. opacipennis Jac, 

 from Colombia, but difiers entirely in the shape of the thorax 

 and the colour of the underside and legs. 



Cacoscelis c^ruleipennis, sp. n. 



Pale fulvous, the antennse (the first joint excepted) black; head 

 and thorax impunctate ; elytra dark violaceous blue, finely and 

 closely punctured, with traces of longitudinal sulci. 



Length 7 millim. 



Head fulvous, entirely impunctate, the frontal elevations
