(Plate IV, flg. 29; Plate VI, fig. 29.) 



This species is represented in the collection by a typical specimen 

 labeled with name; "Marquette, Mich., 26.6 [June 26]; Coll. Hub- 

 bard & Schwarz; 9 2." 



Distinctive characters. — This species is at once distinguished from 

 all of the preceding ones of the genus by the equal ^\^dth of the 

 elytral interspaces, the third and fifth of which are not elevated; 

 and from its nearest ally (P. curriei) by the long posterior spot on 

 the elytra and by the moderately coarse s trial punctures. 



Variations. — The length varies from 5.5 to 8 mm., and while the 

 sculpture and color are quite constant there is considerable variation 

 in the spots of scales, both in color and density. Twenty-nine adult 

 specimens were examined. 



Host tree. — Pinus strohus, in thick bark on stump. (As deter- 

 mined by W. F. Fiske.)
