NORTH AMERICAN COLEOPTERA. 205 



In the fully developed very dark specimens, the elytra are scarcely 

 bronzed, the legs are always piceo-testaceous with the anterior coxae pale. 

 When the elytra are pale the bronze surface is more evident, ajid the 

 sides and apex are often narrowly bordered with paler color, the legs here 

 are entirely pale. 



I have before me a small number of specimens in which the abdomen 

 is somewhat more finely and densely punctured. After a careful study 

 of the sexual peculiarities I conclude that these are merely variations 

 from the typical form of loinatus. They constitute from our determina- 

 tion iirorgixinus Sachse. I have been informed that Fauvel considers the 

 latter species identical with sobrinus Er. a conclusion, it seems to me, en- 

 tirely unwarranted by the description. P. vipfrinna Fv. mss. seems to 

 me merely a small form of lomntus. 



Occurs everywhere in our fauna excejtt in the Pacific coast region. 



P. CUiiCtans n. sp. — Form rather slender, piceous, elytra very distinctly 

 bronzed: legs testaceous; antennre piceous, slender, a little longer than the head 

 and thorax, joints all longer than wide ; head oval, slightly quadrate, a few coarse 

 punctures behind the eyes; thorax wider than the head, oval, longer than wide, 

 scarcely narrowed in front, dorsal punctures moderate; elytra wider than the 

 ihoi'ax, conjointly nearly square : surface very distinctly bronzed, and roughlj' not 

 closely punctured, pubescence sparse; abdomen shining, very sparsely pubescent, 

 j»unctures rather coarse and not closely placed ; beneath shining, coarsely and 

 sparsely punctate, pubescence very sparse. Length .28 inch; 7 mm. 



Male. — Anterior tarsi slightly dilated; last ventral segment with a small trian- 

 gular emargination and a triangular impression extending forward. 



i^emf//e.— Anterior tarsi very feebly dilated ; last ventral entire. 



This species might readily be mistaken for foviafns, but the antenna) 

 are entirely piceous, and the elytral and abdominal sculpture coarser. 

 The last ventral of the male has a much smaller emargination, and the 

 anterior tarsi less dilated. 



Occurs in District of (jilumbia i:Ulke). 



I*. eequttliiS n. sp.— Piceous, elytra brownish; legs testaceous; antennae a 

 little longer liian tlie head and thora.x, piceous, two basal joints testaceous; head 

 oval, narrowed behind the eyes ; sides nearly straight, hind angles not punctulate ; 

 thorax oval, a little wider than the head, a little longer than wide, narrowed in 

 front, dorsal punctures ratber deep and closely placed ; elytra a little wider than 

 the thorax, conjointly nearly square, punctures moderately coarse but not densely 

 placed, color brownish; surface shining, sparsely pubescent; abdomen piceous, 

 the margins of the segments paler, punctures coarse but not dense; beneath .■simi- 

 larly punctured. Length .20 inch ; 5 mm. 



A/d/e.— Anterior tarsi moderately dilated ; last ventral with a feeble broad emar- 

 gination and a narrow longitudinal impression. 



/'ewin/e.— Anterior tarsi feebly dilated; last ventral entire.
