 (as developed by Dr. LeConte) being given in the table. Length, .44 

 in. =11 mm. 



Habitat : Northeastern America. 



P. vitreus Z>ej. — Length, .46 in. = 11.5 mm. 



Habitat : New Hampshire, California and Alaska.

P. orinomum Kirby. PI. VII, fig. 10. — Very close to the pre- 

 ceding. Length, .45 in. = 11 mm. 



Habitat : Nova Scotia, Canada, Lake Superior, Oregon, British 

 Columbia. 



P. erythropus DeJ. PI. VII, fig. 11. — A small black shining 

 species, with reddish legs, thorax subquadrate, angles much rounded. 

 Posterior tarsi with four joints grooved e.xternally. Length, .33-. 34 

 in. = 8-8.5 i^^n""- 



Habitat: Northeastern America, west to Colorado. 



P. patruelis Dej. — 'VfxXhfe mora lis and corriisculus forms a small 

 group in which the scutellar stria is long, the prothorax feebly nar- 

 rowed behind and the basal impressions single. The hind tarsi have 

 three joints grooved on the outside. Length, .30 in. = 7.5 mm. 



Habitat: Northeastern America, west to Wisconsin and Iowa, 

 north to Alaska. 



P. femoralis Kirby. — Differs from the preceding by characters 

 given in table. The variety desidiosus Lee, has the stride more strongly 

 punctured than in the type. Length, .30 in. = 7.5 mm. 



Habitat: Illinois and Missouri (var. desidiosus). New York, 

 Canada, Pennsylvania, Wisconsin and Iowa. 



P. corrusculus Lee. Smaller than either of the preceding, hind 

 angles of prothorax obtuse. Length, .20 in. 1= 5 mm. 



Habitat : New York, Massachusetts. 



P. vindicatus Mann. — Oblong-ovate, above cupreous, shining, 

 beneath black, thorax subquadrate, moderately narrowed behind. 

 Basal impressions single, impunctate, hind angles somewhat obtuse.
