Tins s})e(;ics n))])('ar.s to be closely allied to P, torosus, 

 YjV., a sj)ecies Avliieh 1 know only by description. P. dnx 

 would seem to be l:ir<^er than torosus, and it has not the 

 apical segments of the hind body rugose; other details of 

 Ej-ichsou's description of /*. forosns do not seem very 

 a])])licable to J\ dux, so that- il" a com]iarison of the two 

 species were made it is possible they might be Ibund to 

 differ in other minor points.

 ])ei'niti(ris, ])arce puuctatis; thorace oblongo, dorso biseria-

 adsperso ; elytris thorace vix longioribus, subnitidis,

 punctato. Long. cor[). 10 lin. 



l^ilongate and ])arallel ; antennae nearly twice as long as 

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

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

 Head shining black, with a few large punctures about the 

 middle, and also some very miiuit(^ ])uuctures ; the hind 

 angles rather closely ])unctured. Thorax distinctly longer 

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

 the sides, with the hind angles much rounded ; very 

 shining black, spai-iugly ])unctnrc(l, near the middle two 

 irregular I'ows of ])unctures, and with some other scattered 

 pmictures about the sides and front, and the surface 

 besides is sprinkled with very minute punctures. Elytra 

 scarcely longer than tlu^ thorax, rather coarsely but not 

 denselv ])unctured. 1 1 iud body rather (;()arsely and closely 

 ])uui;tured, its extremity reddish, truncate, and with a 

 small spine oix each side the truncatioii ; the aj>ical seg- 

 ments rather more sparingly ])unctured than the preceding 

 ones. The legs are ])itchv, with the tarsi reddish; the 

 metasternum has a fine channel along the midiUe. 



Tapajos; a single female specimen, from which the 

 ])ul)escence has been removed. This sj)ecies is about the 

 size of our Oci/pux afrr. It is larger and more ])arallel 

 than the North American J\ /u'c/jhs, and di tiers there- 

 from by the large tooth of the mandibles.
