StaphylinidcB of the Amazon V^allcy. 331 



This species presents a very great resemljlance to 

 P. laxiis, yet the structure of the male intromittent organ 

 is very different. 



18. Pinophilus bicolor, n. sp. Nitidus, rufus, capite 

 abdoraineque nigris, antennis, palpis, pedibusque testaceis ; 

 thorace basin versus angustato, cum ely tris fortiter parcius 

 punctato. Long. corp. 4| — 5 lin. 



Mas : abdomine segmento 7° ventrali producto, apice 

 l£e\a, truncato. 



Antenn;« slender, moderately long, yellow ; 3rd joint 

 about as long as 2nd. Palpi pale yellow ; mandibles red- 

 dish. Head rather small, black and shining, the vertex 

 coarsely punctured, in front of this a very shining space, 

 the front part Avith a few coarse punctures, and with some 

 fine ones scattered. Thorax shining red, about as long 

 as broad, slightly rounded at the sides and distinctly nar- 

 rowed behind, with coarse scattered punctures, wanting on 

 a small space near the front angles and about the hind 

 angles, and not so dense along the middle. Elytra shining 

 reel, elongate, deeply and rather coarsely but sparingly 

 punctured. Hind body black, rather coarsely but not 

 closely punctured. Legs short, pale yellow, the coxoe red. 



In the male the ventral plate of the 7th segment of hind 

 body is produced ; the extremity is truncate, not in the 

 least emarginate, the apical part shining and impunctate ; 

 the ventral plate of the 8th segment forms part of the 

 intromittent organ, and is bihamate at the extremity. 



Ega; four individuals, two $, two $. 



19. Pinophilus Batesi, n. sp. Nitidus, rufus, capite 

 abdomineque apice nigris, thorace ]nceo-rufo, antennis, 

 palpis, pedibusque pallidis ; thorace elytrisque fortiter sat 

 crebre punctatis. Long. corp. 65 lin. 



Mas: abdomine segmento 7° ventrali producto, apice 

 angusto, simplice. 



Antenna slender, moderately long ; 3rd joint consider- 

 ably longer than 2nd ; the basal joint pale yellow, the rest 

 rather darker. Palpi j^ale yellow; mandibles and labrum 

 red. Head shining black, vertex coarsely punctured, 

 clypeus with two large punctures on its front edge in the 

 middle ; in front of the eyes a transverse curved patch of 

 ten or a dozen coarse punctures, behind these a very 

 smooth and shining space. Thorax as long as broad,
