NORTH AMERICAN COLEOPTERA. 218 



number uf specimens before me, one having but throe dorsal punctures 

 on one side while another has five. 



All the specimens observed are from the north shore of Lake Superior. 



P. Sieg^waldi Mann.— Black, lege piceous; elytra sliglitly bronzed ; antennae 

 piceous, neiirly as long as the head and thorax, joints 7-10 as wide as long: head 

 orbicular, a little larger in the male, hind angles not punctulate ; thorax not wider 

 than the head of the male and scarcely larger, sub-qiuidrate, not narrowed in front, 

 dorsal punctures five, moderately deep, rather closely placed ; elytra a little wider 

 than the thorax, longer than wide conjointly, coarsely and rather closely punc- 

 tured, sparsely pubescent; abdomen very sparsely punctured and shining, the 

 punctures very much finer than on the elytra; beneath nearly smooth, the punc- 

 tures sj)arse and very distant. Length .26 — .30 inch ; 6.5 — 7.6 mm. 



Male. — Tarsi filiform ; last ventral with a feeble oval emargination surrounded 

 by a narrow depression. 



Female. — Tarsi tiliform ; last ventral entire. 



This species resembles in form and general appearance sordidiis and 

 ccp/uflotes, the elytra are, however, more densely and the abdomen more 

 sparsely punctured than either. 



Occurs from Alaska southward as fur as northern California. 



P. crassiillis n. sp. — Facies rather robust, general color brownish, shining; 

 head Mack : antenuse brown, rather stout, not as long as the head and thorax, 

 joints 4-10 not wider than long aud gradually broader; head quadrate oval, black, 

 shining, a few coarse punctures behind the eyes; thorax oval, not narrowed in 

 front, nearly as wide as long; surface shining, dorsal punctures five, moderately 

 impressed; elytra a little wider than the thorax; sides slightlv arcuate a little 

 broader conjointly at apex than long, convex, shining, punctures relatively coarse 

 but irregular in size, sparsely placed, apparently without pubescence; abdomen 

 darker than the elytra, the apices of the segments paler; surface shining, very 

 sparsely pubescent, punctuation finer than the elytra and sparse ; beneath as 

 above; legs pale brown. Length .16 inch; 4 mm. 



Jkfa/e. —Anterior tarsi slender; last ventral segment with an oval emargination, 

 the border of which is membranous. 



Female. — Unknown. 



A small species of peculiar facies from the rather robust form, very 

 shining surface and convex elytra. 



I have seen but one specimen kindly loaned me by Mr. Fauvel, col- 

 lected in Nevada. 



P. clnnalis n. sp.— I'iceous, nearly black; legs pale testaceous: antennaj 

 nearly as long as the head and thorax, piceous, joints 6-10 as wide as long; head 

 oval; sides parallel, hind angles not punctulate; thorax a little wider than the 

 head and longer than wide; sides straight, slightly narrowed in front, dorsal 

 I)unctures five, not large, equidistant ; elytra a little wider but not longer than the 

 thorax, conjointly less wide than long, moderately coarsely punctate, very sparsely
