COLEOPTEIIA. 193 



37. A. leviceps n. sp. — Form rather slender ; abdomen large. Pubes- 

 cence short, erect, fine, extremely sparse ; surface polished. Head very 

 small, twice as wide as long ; interbcular surface very feebly convex, nearly 

 twice as wide as the eye ; longitudinal elevation feeble, crest broadly im- 

 punctate, slightly wider than the lateral portions ; sulcations very feeble ; 

 punctures coarse, sparse, deep, closer in the depressed portions ; ocular lines 

 very convergent, meeting at about one length in advance ; antennae rather 

 short and robust, piceous-brown, slightly darker toward the club, the latter 

 not abrupt ; third joint scarcely one-third longer than the fourth, eighth 

 more robust tban the seventh, slightly elongated ; maxillary palpi long, 

 slender, third joint strongly clubbed ; piceous throughout, basal joint very 

 sligbtly paler. Prothorax small, robust, widest slightly behind the middle, 

 where it is as wide as long ; sides thence very feebly convergent posteriorly 

 and very slightly sinuate ; anterior and posterior margins very long, sub- 

 equal, strongly arcuate ; surface coarsely, rather loosely, and very irregularly 

 punctate ; interspaces convex. Elytra at base distinctly wider than the 

 bead ; sides feebly divergent posteriorly, distinctly longer than the width at 

 base, strongly arcuate near the apices ; together broadly and very strongly 

 emarginate behind ; suture one-third longer than the pronotum ; surface 

 very narrowly and feebly impressed along the suture ; each elytron is also 

 impressed just in advance of the middle point, and also very irregularly so 

 just behind the middle and near the exterior margins ; coarsely, very deeply 

 punctate ; punctures round, nearly evenly distributed, distant by slightly 

 more than their own widths ; interspaces convex. Abdominal segments 

 decreasing uniformly and somewhat rapidly in width, first very slightly 

 narrower than the contiguous elytra ; surface cylindrical ; border obsolete 

 except on the first segment, where it is very narrow ; punctures round, 

 deeply impressed, rather sparse, evenly distributed ; transverse carinae 

 strongly and finely undulated throughout. Legs very slender, black above, 

 tarsi and under surface of the femora and tibiae dark fuscous or piceous- 

 brown ; first joint of the posterior tarsi about as long as the next two 

 together ; fourth joints bilobed, lobes rather inconspicuous ; claws very 

 slender, strongly curvate, bulbous at the base. 



Male. — Unknown. 



Female. — Sixth ventral segment very obtusely and evenly rounded behind. 



Length 2.8 mm. 



Vancouver Island, British Columbia, 1. 



Very readily distinguished from Icetulus, which it somewhat resem- 

 bles by its very small head, and somewhat finer and closer elytral 

 punctuation. 



38. A. politullis n. sp. — Form rather slender. Pubescence very sparse 

 and inconspicuous ; surface very highly polished throughout. Head small, 

 about twice as wide as long ; interocular surface scarcely twice as wide as the 

 eye, nearly flat ; sulcations obsolete ; longitudinal elevation very narrow, 

 impunctate and rather distinct ; punctures very coarse, deeply impressed, 

 nearly evenly distributed, close ; interspaces convex ; ocular lines meeting 

 at one length in advance, nearly straight ; antennae as long as the width of
