1903.] SOUTH-AMERICAN COLEOPTERA. 41 



slightly raised smooth pale spots or patches of irregular shape ; 

 below coloured like the upper surface ; the mesosternal process 

 long and stout. 



Hah. Bahia, Brazil. (A single specimen.) 



Distinguished by the unicolorous upper and under sides and by the 

 broadly flattened terminal joints of the antennae and their colour. 



DORYPHORA IMITANS, Sp. nOV. 



Below black, above fulvous ; thorax flavous, minutely punctured ; 

 elytra finely and irregularly punctured; antennje black, the 

 anterior femora flavous. 



Length 12 millira. 



Head nearly impunctate, palpi black ; antenna? with the 

 terminal joints distinctly widened, black, the basal joint flavous ; 

 thorax scarcely more than twice as broad as long, the sides 

 straight at the base, rather strongly obliquely narrowed anteriorly, 

 the anterior angles pointed, the disc finely and rather closely 

 punctured, the punctures of unequal size ; scutellum fulvous ; elytra 

 regularly convex, finely punctured in irregular double rows near 

 the suture, the sides irregularly punctate, fulvous, the extreme 

 basal margin piceous, the interstices smooth; below black, the 

 anterior femora entirely, the others more or less fulvous below ; 

 the mesosternal process short and broad. 

 Hah. Colombia. (A single specimen.) 



The thorax in this species is less transverse in shape and more 

 suddenly pointed anteriorly than in D. hahiaensis ; the elytra are 

 difi"erently sculptured and the mesosternal process is much shorter. 



DORYPHORA FLAVOANNULATA, Sp. IIOV. 



Oblong, below black, above and the legs dark fulvous ; thorax 

 remotely and strongly punctured at the sides; elytra regularly 

 punctate-striate, an interrupted ring-shaped band from the base 

 to the middle and an entire similar ring near the apex, flavous ; 

 antenna? and the last abdominal segments pale flavous. 



Length 9 millim. 



Head minutely punctured, pale fulvous, labrum testaceous; 

 antennce extending beyond the base of the thorax, pale fulvous, 

 terminal joints subquadrately widened ; thorax nearly three times 

 broader than long, the sides straight, rounded near the anterior 

 angles only, the disc finely and remotely punctured, the sides 

 more strongly so, but little flattened; scutellum pale; elytra 

 oblong and parallel, moderately convex, regularly and moderately 

 strongly punctate-striate, fulvous, sometimes with a slight greenish 

 tint, a ring-shaped band, interrupted at its inner and posterior 

 margin, extending from the base to the middle and another nearly 

 round and uninterrupted ring near the apex, obscure flavous ; below 

 black, with the exception of the fulvous legs and similarly coloured 

 mesosternal process, the latter long and stout, slightly curved,
