median ventral spine long and pale; connexivum with large black macula- 

 tions at joints; femora unicolorous yellow-brown to dark brown in some, 

 with punctures red-brown to nearly black; tibiae unicolorous, reddish 

 brown; tarsi reddish, mostly lighter than tibiae and more reddish, but in 

 some cases darker. 



Described from ten specimens collected as follows: Type (male). Rock- 

 away Beach, IV 17, 1912, by Alan S. Nicolay (Olsen Coll.) ; allotype (fe- 

 male), Rockaway Beach, V 17, 1910, by C. E. Olsen (Olsen Coll).; para- 

 types (males), Amherst, Mass., V 16, 1910, and Amagansett, L. I., by G. 

 P. Engelhardt (Bueno Coll.) ; Wyandanch, L. I., VIII 30, 1914, by F. M. 

 Schott (Olsen Coll.) ; paratypes (females). Promised Land, L. I., IX 24, 

 1910, and Wilmington, N. C, IV 16, 1916, by W. T. Davis (Barber, Coll.) ; 

 Yaphank, L. I., IX 25, 191,1, by J. R. de la Torre-Bueno (Bueno Coll.) ; 

 Wyandanch, L. I., VIII 30, 1914, by F. M. Schott (Schott Coll.); New 

 Brunswick, N. J., V 18 (Amer. Mus. Nat. Hist. Coll.). Mr. Bueno's speci- 

 mens from Amherst, Mass., and Yaphank, L. I., were both beaten from 

 pine, whereas Mr. Schott's specimens were taken beating oak ; the writer 

 has taken two specimens in washup on Rockaway Beach, one of which is 

 in Mr. H. G. Barber's collection (not mentioned as type). 



This species is readily distinguished from P. maculiventris by 

 the broader and proportionally shorter anterior part of head 

 (from in front of eyes) ; by its straighter anterior-lateral margins 

 of pronotum on which the pale band along edge is not so decided, 

 in some specimens almost obsolete ; by the rounded humeri and 

 lack of humeral spine; by median ventral spots being large, dull 

 red-brown and not sharply defined when present, but never shin- 

 ing black ; by the venter being profusely marked with red and red- 

 brown spots and blotches ; by the larger size, more robust appear- 

 ance and general color being darker and more reddish dorsally 

 and much darker and redder ventrally. From P. serieventris it 

 is distinguished by its much larger size, long median ventral spine, 

 absence of darker subapical annulus on the femora, more reddish 

 color especially ventrally, by the median row of ventral spots be- 

 ing large dull red-brown and not sharply defined. 



The author wishes to acknowledge with thanks the valuable as- 

 sistance rendered by Messrs. H. G. Barber, J. R. de la Torre 

 Bueno and other collectors in turning over their material for 

 study.
