loc. cit. ISHO. 



The body, antennae and legs an: entirely black, and the elytra have an oblique red 

 spot from the humerus backward and inward toward the suture. The margins of the spot 

 arc i rregular. 



Length .22-. 30 inch. 



Abundant in the Southern States, rarely found in Pennsylvania. 



P. oregonense, Loc, Pacif. R. R. Rep. IX, A pp. T, p. 51. 



This species is very closely allied to the following, and it is doubtful whether they 

 should he retained as distinct. The only differences being in the rather rounder form 

 and deeper frontal impression of this species. Should these two prove to be identical, its 

 distribution would prove nearly as extended in the Northern regions as nanus in the 

 Southern. Oregoncso is always brownish in color, never black; the antennee are pale; 

 the presternum horizontal, tip acute and prominent. 



Length .20-.26 inch. 



Distributed from Oregon to Fort Tejon, Cal. 



P. am c vie anum, Lap. et Brulle, loc. eit. 358. 



This species has heretofore borne the name of suhcostatum, Lap., in our collections 

 and has been so distributed. The differences between it and oregonense have already 

 been adverted to. 



Length .20-.2G inch. 



Abundant in the Northern States and Canada.

Differs from both the preceding, in having the front convex, without any transverse or 

 intra-ocular impression. The presternum is likewise prominent and horizontal. The sur- 

 face is less shining than either of the preceding, and while the thorax and head are black 

 the elytra are brownish. The antennae are pale brown and the legs ferruginous. 



Length .20-.2fi inch. 



Middle and Southern States.

" Broadly oval, of the form of rnficolle, black, very shining, with a blackish submctal- 

 lic lustre to the elytra, with the sides toward the apex brownish ; antennae, palpi and legs 

 reddish brown; head rather densely and coarsely punctured, tborax rather densely but 

 less coarsely punctured, with two feeble impressions along the basal margin ; elytra with 

 stria) of rather large punctures, with the interstices rather densely and finely punctured ;
