ClCINDELID^; AND CARABID/E 45 



Brevipenne must be very closely allied to robustum, the form and 

 sculpture being almost exactly the same, but the black suture, 

 expanded before the apex into an unusually large transversely 

 rhomboidal area, is a character wholly at variance with robustum, 

 as described by Horn, and this, in conjunction with the widely 

 separated habitats Nova Scotia and Ohio leads me to believe 

 that we have to deal with two distinct though allied species. 



Leistus Froh. 

 The following belongs near ferruginosus Mann : 



Leistus nigropiceus n. sp. Form rather slender, moderately convex, 

 polished, piceous-black to castaneous in color, the legs concolorous, the 

 antennae very slender, testaceous, with the basal joint a little darker; 

 head smooth, four-fifths as wide as the prothorax, the sides very rapidly 

 oblique behind the eyes; prothorax three-fifths wider than long, strongly 

 rounded and dilated at the sides, strongly narrowed basally, the sides 

 deeply sinuate for a short distance before the right and very sharp angles; 

 impressions rather deep and punctured, the median stria feeble; sides 

 abruptly but not broadly reflexed; elytra two-thirds longer than wide, 

 two-fifths wider than the prothorax, rather distinctly broadening pos- 

 teriorly, the sides broadly arcuate; humeri broadly rounded; striae fine, 

 distinctly but finely punctate, impressed, the intervals feebly convex, the 

 third with three distinct foveae near the third stria; legs rather long, 

 slender. Length 7.4-8.0 mm.; width 2.65-2.8 mm. British Columbia 

 (Metlakatla), Keen. 



This is probably the form appearing in our lists under the name 

 piceus Froh., but on reading the description of analis Dej., which 

 is said to be synonymous, it appears clear that nigropiceus has the 

 anterior thoracic impression much deeper, since it is as deep as the 

 basal, and the median line feebler. It is more slender and with 

 more cuneate elytra and larger head than ferruginostis and appears 

 to be very abundant. 



Pelophila Dej. 



The species of this genus are northern subarctic in range and, 

 though probably rather numerous in Alaska and various parts of 

 the Hudson Bay regions, are so far as described very few in number. 

 The following species was sent to me under the name ulkei, but is 

 evidently different : 



Pelophila shermani n. sp. Moderately stout, convex, shining, aene- 

 ous-black, the legs and antennae black throughout; head four-fifths as 

 wide as the prothorax, smooth, moderately biimpressed, the impressions
