326 Mr. D. sTuirp's Coiitrihiitioiis to the 



punctured, the elytra more coarsely and less densely punc- 

 tured and not so dull. The male has the 7th segment 

 formed as in P. incultus, but the notch is narrower in 

 P. proximus. 



Tapajos ; two specimens, one of which is brown, being- 

 immature. 



1 1. Pinophilus ant/ustus, n. sp. Niger, antennis, palpis, 

 pedibusque pallidis ; thorace quadrato, fequali, opaco, 

 })arcius ol)solete punctato ; elytris opacis, fortiter crebre 

 punctatis. Long. corp. 4^, lin. 



Narrow ; antennae yellow, slender, moderately long, 

 3rd joint a little longer than 2nd. Palpi yellow ; mandi- 

 bles, front edge of clypeus and antennal tubercles pitchy. 

 Head dull, front part with sparing coarse punctures, 

 punctuation of the A-ertex obsolete. Thorax quite as long 

 as broad, quite straight at the sides, not narrowed behind, 

 quite as broad as the elytra ; its surface dull, sprinkled 

 with distinct, though very slightly impressed, moderately 

 fine pnnctures. Elytra slightly longer than the thorax, 

 dull, rather coarsely and moderately closely punctured, 

 the interstices larger than the punctures. Kind body 

 rather slender, its punctuation indistinct, rather coarse, 

 but shallow and not dense, concealed by a coarse pubes- 

 cence. The legs are pale yellow, with the coxae reddish ; 

 the anterior tarsi very broad. 



Tapajos; two specimens, both females; the extremity 

 of the hind body is formed as in P. incultus $, to which 

 species, as well as to P. proximus, the present species is 

 closely allied, but it may readily be distinguished by its 

 more slender form and more sparingly punctured elytra. 



12. Pinophilus ohlatus, n. sp. Elongatus, niger, opacus, 

 antennis gracillimis, palpis pedibusque pallidis ; thorace 

 qviadrato, obsoletissime punctato ; elytris peropacis, dense

 laevi, apice truncato, hand emarginato. 



Antennre very slender, very elongate, the incrassation 

 at the extremity of each joint less than in the other species ; 

 3rd joint slightly longer than 2nd ; 8th joint about as 

 long as 3rd (the three apical joints are wanting in the 

 individual described). Head small, dull, with the excep-
