 from New Jersey to Florida, Texas and Mexico, in 

 the coastwise states, attacking many kinds of conif- 

 erous and deciduous trees. Ziininermaun observed 

 that in South Carolina they are found mostly in 

 pine logs, remaining commonly about the foot of the 

 tree where their presence is easily known by the 

 large heaps of worm-dust which they push out of

 flying freely in early morning. In hardwood trees 

 they are inquilinous in burrows of other insects making their 

 own more especially in the bark of the lower part of coniferous

Male elytra deeply striate, with a posterior process at the end of third 

 interval, and a large compressed obtusely truncate one at the junction of 

 the fifth and eighth intervals. Ventral surface opaque, densely punc- 

 tured. Female similar to P. flavicornis. Length 4 mm.

 being an exaggeration of those of flnrlrornis, that the two are 

 not distantly related.

Female, apical part of front smooth. Prothorax scarcely punctulate. 

 Elytra transversely impressed near tip; without posterior process. Ven-
