13. Chalcophana uniformis, sp. nov. 



Entirely dark rufous, with the exception of the last five joints of 

 the antennae, the apex of the tibiae, and the tarsi. Thorax finely, 

 elytra deeply geminate-punctate-striate, and more or less costate. 



Length 3-3 1 lines. 



Head exactly punctured as in semirufa, the antennae also coloured as 

 in that species. Thorax a little more finely punctate. Elytra distinctly 

 and closely punctured, the punctures running together in pairs, the 

 interstices either raised over the whole disk in costae, or only distinctly 

 visible towards the apex. The underside rufous ; extreme apex of 

 tibiae and the tarsi black. 



Hab. Costa E-ica. 



This species may possibly be only a variety of C. semirufa ; but 

 the uniform coloration, the punctuation of the elytra approached in 

 pairs distinguish it sufficiently from that species, while the colour of 

 the first six joints of the antennae will separate it from species in 

 other respects similarly coloured. 



14. DORYPHORA BRUNNEIPENNIS, Sp. UOV. 



Broadly ovate, narrowed behind, below black ; antennae with the 

 last two joints yellowish white. Head, thorax, and elytra rufous, 

 opaque. 



Length 6 lines. 



Head strongly but not closely punctate, brown with a greenish 

 tint ; antennae brownish aeneous, last two joints whitish. Thorax 

 with the sides parallel, the anterior angles acute ; surface with the 

 same-sized punctures as the head, but closely and uniformly dis- 

 tributed. Scutellum smooth, broadly triangular. Elytra broader at 

 the base than the thorax, very convex at their first third, from there 

 strongly declining to the apex, the latter pointed ; surface finely and 

 irregularly punctured and longitudinally aciculate, the intervals finely 

 alutaceous, opaque, of a uniformly rufous colour. Beneath black ; 

 mesosternal process robust, long, slightly curved. Legs rufous. 



Hab. Columbia. 



Collection Jacoby. 



15. Doryphora flavipennis, sp. nov. 



Greenish black, shining. Head and thorax strongly punctate. 

 Elytra sparingly irregularly punctured, flavous, a sutural stripe 

 narrowed towards the apex, greenish black. 



Length 5£ lines. 



Head more strongly punctured near the apex than at the vertex ; 

 antennae with the last five joints flattened and widened, the first five 

 joints testaceous, stained with greenish aeneous above, the rest 

 fuscous. Thorax more strongly punctured than the head, verv 

 coarsely towards the sides, dispersedly on the disk. Scutellum 

 smooth. Elytra rotundate towards the apex, parallel near the base, 

 sparingly and rather finely punctate without order, the intervals 

 finely aciculate ; the extreme outer margin has a row of punctures, 

 and is accompanied, at, some distance, with another row of double
