FAMILY XI. STAPH YLINID^E. 



Putnam County; scarce. March 26-October 10. Sifted from 

 damp vegetable debris. 



Tribe II. PINOPHILINI. 



Elongate, slender, sub cylindrical species having the fourth joint 

 of maxillary palpi as long as the third and obliquely hatchet-shaped. 

 Two genera compose the tribe, both of which occur in Indiana. 



KEY TO GENERA OF PINOPHILINI. 



a. Abdomen distinctly margined ; species black or piceous. 



LIX. Pinophilus. 



aa. Abdomen not margined ; species usually pale yellow. 



LX. Palaminus. 



LIX. Pinophilus (Ira v. 1802. (Gr., "filthiness + loving. ") 



Rather large blackish species having the head short, wider than 

 long, about as wide as thorax, its base truncate ; neck one-half the 

 width of head; antennas very slender, reaching nearly to base of 

 thorax ; mandibles long, strongly curved, each with a blunt median 

 tooth which is notched at apex ; eyes large, very close to base of 

 head ; basal joint of hind tarsi as long as the next three, fourth joint 

 bilobed. Only isolated descriptions of the five North American spe- 

 cies are extant. Two are known from Indiana. 



844 (2585). Pinophilus latipes Gray., Mon. Col. Micr., 1806, 202. 

 Elongate, parallel. Black, feebly shining, sparsely clothed with gray- 

 ish hairs. Antenna?, legs and hind margins of abdominal segments pale 

 reddish-yellow. Head very finely and sparsely punctate, with a number of 

 coarse, deep punctures above and behind the eyes. Thorax slightly longer 

 than wide; base and apex truncate; sides nearly straight, feebly converg- 

 ing from apex to base; disk coarsely, rather sparsely and irregularly punc- 

 tate. Elytra slightly wider and nearly one-half longer than thorax, coarsely, 

 deeply and densely punctate. Abdomen at base a little narrower and more 

 finely and sparsely punctate than elytra. Front tarsi of male short, very 

 strongly dilated, the joints membranous and overlapping. Length 13-15 mm.

 more finely and deeply punctate, but slightly longer than thorax. Abdo-
