334 ]Mr. D. Sharp's Contrihittions to the 



in the female tliei-e is a small but very sharj)ly defined 

 notch in the middle of tlic extremity of the ventral plate of 

 the 7th segment ; the plate of the 8th segment is rather 

 broad, its extremity emarginate so as to be acuminate on 

 each side. 



Tapajos ; four specimens, one <J, three $. 



Closely allied to P. dehilis, but narrower and paler, with 

 the thorax more coarsely punctured and the sexual cha- 

 racters different in both sexes. 



22. Pinopliihis affinis, n. sp. Nigricans, nitidus, an- 

 tennis, palpis, pedibiisque flavis ; thorace quadrato, basin 

 versus leviter angustato, fortiter punctato ; elytris crebre 

 profunde punctatis. Long. corp. 3g lin. 



Mas latet. 



Antenna? yellow, short : 3rd joint rather shorter than 

 2nd. Head black, with the mandibles and edge of the 

 clypeus reddish, punctured as in P. dehilis, but with the 

 fine sparing punctui-es less distinct. Thorax about as 

 long as broad, slightly narrowed behind, pitchy black, 

 shining, coarsely punctured, the punctures Avanting on a 

 small space near the front angles ; in the middle, in front 

 of the base, slightly elevated, the punctures leaving this 

 part free. Elytra about one-third longer than the thorax, 

 shining, blackish, with the hind margin pitchy red, deeply 

 and rather coarsely and closely punctured. Hind body 

 blackish, with the margins of the segments pitchy, rather 

 closely and finely punctured. Legs pale yellow. 



The female has the extremity of the ventral plate of the 

 7th segment simple, that of the 8th formed as in P. minor. 



St. Paulo ; a single specimen. 



Though very closely allied to P. dehilis, I have no doubt 

 this is a distinct species; the thorax is more coarsely punc- 

 tured, and slightly narrowed behind; the last joint of the 

 maxillary pal])i a little shorter, the legs a little longer ; 

 the male would probably offer good distinctive characters. 



23. Pi7iophilus rf/ej}s,-n. sp. llufo-castaneus, nitidulus, 

 abdomine scirmentis duobus ultimis dorso infuscatis, an- 

 tennis geniculatis, palpis ])edibusque albidis ; thorace 

 biseriatim punctato ; elytris fortiter punctatis. Long. 

 Corp. 3i lin. 



Mas: tibiis anterioribus mucronatis, abdomine segmento 

 7° ventrali subproducto, medio obtuso.
