32 MEMOIRS ON THE COLEOPTERA. 



Atheta brumalis n. sp. Stout, not parallel, moderately convex, somewhat 

 shining, the abdomen polished, the punctures fine, asperate and close-set; color 

 black or blackish, the elytra dark piceo-luteous, the legs pale, the antenna 

 black, piceous basally; head moderately small, the eyes at nearly their own 

 length from the base, the carinse very fine, not quite entire; antennae long, 

 rather stout but subparallel, the outer joints moderately transverse, the second 

 a little shorter than the third: prothorax rather small, transverse, parallel 

 but only very moderately rounded at the sides, much wider than the head and 

 correspondingly markedly narrower than the elytra, the latter larger, only 

 moderately transverse, very much longer as well as wider than the prothorax; 

 abdomen parallel, slightly narrowing apically, much narrower than the elytra, 

 the fifth tergite barely as long as the fourth, the sixth (cf) with a small and 

 narrow, internally concave auricula at each side, projecting behind very 

 slightly, the apex between them broadly, evenly and very feebly sinuate 

 throughout the width and scarcely at all modified; mesosternal process pro- 

 jecting rather unusually far between the coxae and drawn out but not very 

 finely aciculate at tip, approaching the triangular metasternal projection 

 rather closely. Length 2.8 mm.; width 0.77 mm. British Columbia (Met- 

 lakatla), J. H. Keen. 



The sexual characters seem to distinguish this species from the 

 very inadequately described metlakatlana, of Bernhauer. 



Atheta carlottae n. sp. Resembles the last very closely but with a larger 

 prothorax and tapering abdomen, stout, subfusoid, similar in coloration, the 

 fine asperulate sculpture denser, the lustre duller; head moderate, the eyes 

 at evidently less than their own length from the base, the carinae fine but 

 virtually entire; antennae a little longer, moderately stout, the second joint 

 distinctly shorter than the third, which is notably longer than in brumalis, 

 the outer joints but slightly transverse; prothorax moderately transverse, 

 parallel, more rounded at the sides, much wider than the head but only a 

 little narrower than the base of the elytra, the latter large, moderately trans- 

 verse, much longer than the prothorax; abdomen gradually feebly tapering 

 and with nearly straight sides from base to apex, at base much narrower 

 than the elytra, the fourth and fifth tergites equal in length, the sixth (d 71 ) 

 with a small narrow auricle at each side of the apex, scarcely at all projecting 

 posteriorly, the apex broadly and feebly emarginate from side to side in 

 an even and very obtuse angle, the edge nearly even but the adjoining sur- 

 face feebly and briefly fluted, giving a slight appearance of crenulation; 

 sterna nearly as in 'brumalis but with the metasternum rather shorter and 

 more obtusely angulate; basal joint of the hind tarsi a little shorter than the 

 second. Length 2.7 mm.; width 0.8 mm. Queen Charlotte Islands (Mas- 

 sett), Keen. 



Distinguishable from brumalis, to which it is rather closely allied, 

 by the more elongate antennae, larger and more laterally rounded 

 prothorax, tapering abdomen and sexual, and, to some extent, the 

 sternal characters. 



Atheta blandita n. sp. Moderately stout and convex, not parallel, shining,
