locality; tlic species appears allied to P.javanus, Er., and 

 its Indian allies, rather than to the other Austro-Columbian 

 species ; this makes me think it possible there may be an 

 error in the indication of its locality. 



9. Pinophilus incultus, n. sp. Niger, omnino opacus, 

 antennis, palpis, pedibusque pallidis ; thorace quadrato, 

 obsoletissime punctato; elytris creberrinie sat fortiter 

 ruguloso-pmictatis. Long. corp. 41 lin. 



Mas : abdomine segmento 7° ventrali apice medio 

 emarginato. 



Antennas yellow, very slender, 3rd joint about as long 

 as 2nd. Head short, black, mandibles and front of clypeus 

 pitchy red, dull, the front part with large distant punctures, 

 the vertex on each side coarsely but obsoletely punctui-ed. 

 Thorax not quite so long as broad, slightly narrowed 

 behind, very dull, sparingly and extremely obsoletely 

 punctiu-ed ; in the middle in front of the base with a short, 

 very obscure, longitudinal elevation. Elytra a little longer 

 than the thorax, quite dull, densely punctured ; the punc- 

 tures moderately coarse, the interstices rugidose. Hind 

 body narrow, quite dull, indistinctly punctured, the pmic- 

 tuation obscured by a coarse pubescence. Legs pale 

 yellow, Avith the coxae dusky reddish, the front tarsi very 

 broad. 



In the male there is a small but distinct notch at the 

 extremity of the ventral plate of the 7 th segment of the 

 hind body ; the ventral plate of the 8th segment is enfolded 

 by the dorsal plate ; it is narrowed towards the extremity, 

 and furnished there with two small hooks placed at right 

 angles to the rest of the plate ; in the female this plate is 

 broader and visible, and has a triangidar notch at the 

 extremity. 



Tapajos ; several specimens ; one immature specimen is 

 quite pale brown ; I have also a male specimen from Ega 

 which differs only in being broader and a little more 

 depressed. 



10. Pijiophilus proximus, n. sp. Niger, opacus, an- 

 tennis, palpis, pedibusque pallidis ; thorace quadrato, parce 

 obsolete punctato ; elytris dense fortiter ruguloso-punctatis, 

 subopacis. Long. corp. 4| lin. 



This species differs fi-om P. incultus only by some 

 details of punctuation ; the thorax is rather more distinctly
