This species appears to be closely allied to P. torosus, 

 Er., a species which I know only by description. J\ dux 

 would seem to be larger than forosus, and it has not the 

 apical segments of the hind body rugose ; other details of 

 Erichson's description of J\ torosus do not seem very 

 applicable to /-*. dux, so that if a comparison of the two 

 species Avere made it is possible they might be found to 

 differ in other minor points. 



2. Pmophilux ater, n. sp. Niger, antennis, palpis, 

 tarsis, abdominisque a])icc obscure rufis ; capite thoraceque 

 pernitidis, parce punctatis; thorace oblongo, dorso biseria- 

 tim punctato, pra^ter punctos majores punctis minimis 

 adsperso ; elytris thorace vix longioribus, subnitidis, 

 fortiter sat crebre punctatis ; abdomine fortiter sat crebre 

 punctato. Long. corp. 10 lin. 



Elongate and parallel ; antenna3 nearly twice as long as 

 the head, dull red ; the basal joints stout, the 3rd joint 

 distinctly longer than 2nd. jNIandibles with a long tooth. 

 Head shining black, with a few large punctures about the 

 middle, and also some very minute punctures ; the hind 

 angles rather closely ])unctured. Thorax distinctly longer 

 than broad, quite as broad as the elytra, quite straight at 

 the sides, with the hind angles much rounded ; very 

 shining black, sparingly pimctured, near the middle two 

 irregular rows of punctures, and with some other scattered 

 punctures about the sides and front, and the surface 

 besides is sprinkled with very minute punctures. Elytra 

 scarcely longer than the thorax, rather coarsely but not 

 densely punctured. Hind body rather coarsely and closely 

 })unctured, its extremity reddish, truncate, and Avith a 

 small spine on each side the truncation ; the apical seg- 

 ments rather more sparingly pimctured than the ]>receding 

 ones. The legs are pitchy, Avith the tarsi reddish ; the 

 metasternum has a fine channel along the middle. 



Tapajos ; a single female specimen, from Avhich the 

 pubescence has been remoAcd. This species is about the 

 size of our Ocypus ater. It is larger and more parallel 

 than the North American P. pic/'pes, and differs there- 

 from by the large tooth of the mandibles. 



3. Pinophilus rectus, n. sp. Elongatus, parallelus, 

 niger, antennis, palpis, pedibusque rufis ; capite thoraceque 

 nitidis, hoc oblongo, crebre irregulariter punctato, linea
