 (Plate IV, fig. 27.) 



This species is represented in the collection by a typical specimen 

 labeled with the name; ''Marquette, Mich., 27.6 [June 27]; Coll. 

 Hubbard & Schwarz; 9 1." 



Distinctive characters. — This species is closely allied to P. fraseri, 

 from which it is distinguished by its medium size, moderately long 

 beak, and the regular convex pronotum without broad impressions. 



Variations. — The length varies from 4.8 to 5.7 mm. and as usual there 

 is considerable variation in color due to rubbed and immature speci- 

 mens. Forty-one specimens were examined, including all stages and 

 work. 



Host tree. — Ahies halsamea, in thick living and dying bark on trunks 

 of living and dying trees and stumps of storm-broken trees.

 'Tisgah Mt., N. C, altitude 5,000 ft.; A. D. Hopkins, collector;

 distinguished by its large size, very long beak, and the moderately 

 convex pronotum with basal and oblique subdorsal impressions. 



Variations.— The length varies from 4.6 to 9.1 mm. and there is 

 considerable variation in color, size of spots and punctures, length of 

 beak, and impressions of pronotum. One hundred and six specimens
