Of subquadrate, parallel shape ; the head sparingly and finely 

 punctured, dark blue, subopaque, labruni testaceous, stained with 

 black; antennee extending below the base of the thorax, black, 

 apex of terminal joints fulvous, the latter joints widened but 

 longer than broad ; thorax of usual shape, the sides strongly 

 rounded anteriorly, the anterior angles mucronate, the disc very 

 minutely and rather closely punctured, of the same colour as the 

 head ; scutellum black, shining ; elytra finely punctured in closely 

 approached rows, which are faii'ly regular even at the sides, the 

 interstices minutely granulate and partly aciculate, their epipleurse 

 blue without, testaceous within, the mesosternal process long and 

 straight. 



Hah. Peru. (A single specimen.) 



This species cannot be referred to I). 2)rcisina Erichs. : the elytra 

 are violaceous and the rest of the insect is dark blue, not green ; 

 the sculpturing of the thorax and elytra is different, and the latter 

 are neither widened posteriorly nor produced at the apex as Stal 

 states in his description of the species. The punctation of the 

 elytra also differs from that of the other blue species from the 

 same locality. 



DORYPHORA SEMINIGRA, Sp. nOV, 



Black, the elytra dark metallic green, subopaque ; thorax very 

 closely punctured at the sides; elytra with closely approached, 

 double, irregular rows of punctures. 



Length 15 millim. 



Head closely punctured round the eyes, black ; antenna? with 

 the terminal five joints widened, slightly longer than broad, 

 entirely black ; thorax twice as broad as long, the lateral margins 

 straight at the base, rounded near the apex, the anterior margins 

 acutely pointed, the surface flattened at the sides, the. latter finely 

 rugosely punctured, the middle sparingly and very finely punctate, 

 black, opaque ; scutellum black ; elytra dark gTeen, moderately 

 shining, strongly punctured in irregular double rows, closely 

 placed ; underside and legs black, mesosternal process shoi-t and 

 stout. 



Hab. Peru. (A single specimen.) 



Larger than D. j^rasina Erichs., of different coloration, and 

 with the sculpturing of the elytra stronger and geminate, the 

 latter have their greatest elevation at the middle. 



DORYPHORA BISTRIGUTTATA, Sp. nOV. 



Greenish black, the thorax closely and strongly punctured, with 

 a fulvous spot at the anterior margin; elytra \erj closely and 

 strongly punctured at the sides, semipunctate-striate near the 

 sutui-e, greenish, each elytron with a round spot near the scutellum, 

 another near the apex, and a ti-ansverse band at the middle
