376 MEMOIRS ON THE COLEOPTERA 



low; inner fovea long, linear, attaining the base, the outer linear, three- 

 fourths as long as the inner, the carina long, confluent with the sides at 

 the basal angles; intervening surface nearly flat, punctate; elytra oblong- 

 oval, not quite one-half longer than wide, a third wider than the protho- 

 rax, rather obtuse behind, the sinus deep and rather narrow; strise fine, 

 subequal throughout, barely at all impressed and feebly punctulate sutur- 

 ally, the scutellar nearly obsolete; intervals almost flat; marginal stria 

 fine, distinct, much nearer to the side than to the eighth, the ocellate 

 punctures very large, widely spaced medially. Length (9?) 7-3 mm.; 

 width 3.0 mm. Alaska (St. Paul Island). 



The anterior tarsi are missing in the type of breviuscuhis, where 

 the abdominal apex has four punctures; the met-episterna are a 

 little longer than wide and the dorsal punctures of the elytra are 

 two in number, well behind the middle and near apical fifth. The 

 subapical sinus of the elytra is rather short and deep in beringi and 

 brevitisculus, but in delicatus it is longer and so feeble as to be barely 

 traceable; in the latter species there is one apical abdominal punc- 

 ture at each side in the male and two in the female. 



I am unable to place any one of these species in the table given 

 by LeConte, but for the present they can come in just after vindi- 

 catus Mann. By far the largest series received in the lot mentioned, 

 amounting to some thirty-six specimens, consists of a species of 

 bright bronze lustre, with the thoracic sides evenly arcuate from 

 apex to the faint and gradual basal sinus, the base narrowly and very 

 obsoletely margined at each side and with slightly convex unmodi- 

 fied surface between the linear fovea and the sides, the elytral 

 striae distinctly impressed internally, with the scutellar rather long, 

 and the dorsal punctures three or four in number; it is probably 

 also allied to vindicates, but is different from any of those here 

 described. 



Paraferonia n. gen. 



Nothing is known to me concerning Pterostichus lubricus Lee., 

 the type of this genus, except the meagre data so far published, 

 but I am disposed to think that is is placed above in a nearly cor- 

 rect position in the series; its resemblance to Piesmus is probably 

 purely superficial, however, and I assume that the met-episterna 

 are short. 



Poecilus Bon. 



The probabilities are that the species described by the writer 

 under the name snowi (Mem. Col., IV, 1913, p. 137) is the same as
