1903.] SOUTH-AMERICAN COLEOPTERA. 45 



extreme margins pale ; scutellum gi-eenish brown ; el3^i'a very 

 regularly punctate-striate, the punctures deep and closely placed, 

 the interstices slightly convex, impunctate, olive-green, the suture 

 piceous or dark fulvous, the ninth interstice obscure flavous, costate 

 posteriorly ; below greenish, the tarsi testaceous more or less 

 mesosternal process stout and straight. 



Hah. Espirito Santo, Brazil [Ffuhstorfe?'). 



Much largei- than D. dejeani Germ, or the allied species, and 

 at once distinguished by the piceous sutviral stripe. I know only 

 a single specimen of this species, which is not an immaculate 

 variety of D. piceo-maculata Jac, on account of the totally differ- 

 ent eljrtral scvilpture. 



DORYPHORA SEXPLAGIATA, Sp. nov. 



Dark violaceous ; antennfe black ; thorax extremely finely and 

 closely punctured, the angles fulvous ; elytra scarcely more 

 strongly punctured, the punctures partly arranged in rows, the 

 interstices finely aciculate, each elytron with three flavous spots, 

 one at the base, one at the margin at the middle, and the third 

 near the apex. 



Length 12 millim. 



Below black with a bluish gloss, above violaceous ; head with a 

 few fine punctures ; antennae black, the terminal joints sub- 

 quadrately widened, one-half longer than broad ; thorax rather 

 flat, the sides straight, the anterior angles slightly tuberculiform, 

 fulvous, the surface extremely finely and rather closely j^unctured ; 

 scutellum black, impunctate ; eljrtra with the greatest convexity 

 at the base, deflexed at the posterior portion, very finely punc- 

 tured in closely approached, irregular rows, violaceous, with a 

 transverse spot near the scutellum, another of oblique shape at 

 the middle of the lateral margins, and a third, subtriangular spot 

 near the apex, bright flavous ; mesosternal process long and straight. 



Hah. Peru. (Two specimens.) 



This species must not be confounded with D. sexmacidata Jac, 

 also from Peru, in which the elytra are either greenish or brown 

 and are strongly punctate ; the spots, although similarly placed, 

 are also of different shape. 



DORYPHORA CYANEOFASCIATA, Sp. nOV. 



Dark fulvous below ; head and thorax fulvo-feneous, minutely 

 and closely punctured, opaque ; elytra regularly and closely punc- 

 tate-striate, testaceous, with a broad transverse oblique band 

 below the base and a narrower band below the middle, as well as 

 the suture, metallic blue, apical portion with minute bluish spots. 



Length 12 millim. 



Head minutely punctured, obscvire feneovis ; labrum and palpi 

 fulvous ; antennae blackish, the lower three or four joints fulvous, 

 terminal joints distinctly widened ; thorax colovired like the head, 

 twice as broad as long, the sides broadly flattened, rounded from 

 the middle to the anterior angles, the latter mucronate, produced
