H2 MEMOIRS ON THE COLEOPTERA 



form of the head ; the evenly thickened antennae to the apex is a 

 distinctive character. 



The following five species belong to the true northern coastal fauna, 

 to the westward of the Cascade range or the prolongation of the 

 Sierras of California. The brumalis group should properly form 

 a part of them, but this group, consisting of brumalis, carlottcz, 

 wrangelica and sumpta, has been alluded to above under wr angelica. 



Atheta relicta n. sp. Stout, subparallel, moderately convex, rather 

 shining, the punctures moderately close, asperate, denser on the elytra, 

 sparse on the head and broadly parted along the middle, fine and numer- 

 ous on the basal tergites, except in the smooth basal impressions, sparser 

 and asperate posteriorly, the abdominal micro-reticulation rather large, 

 transversely polygonal; vestiture rather long and coarse, palish; color 

 deep black, the elytra dark brownish-testaceous, black about the scutel- 

 lum and postero-externally, the legs pale; head large, transverse, fully 

 three-fourths as wide as the prothorax, the eyes prominent, at two-thirds 

 their length from the base, the tempora much less prominent, straight 

 and parallel, then abruptly rounding at base, the carinae fine and far 

 from entire; antennae black, piceous basally, rather long and notably 

 heavy, the third joint longer than the second, fourth as long as wide, 

 fifth nearly so, the outer joints only slightly transverse, the tenth longer 

 than the ninth, the last large, conoidal with the tip obtuse, fully as long 

 as the two preceding; prothorax large, fully one-half wider than long, 

 parallel, distinctly and evenly rounded at the sides, the median line (cf ) 

 feebly but rather broadly and distinctly impressed from somewhat before 

 the middle to the base; elytra large, moderately transverse, with diverg- 

 ing sides, at base only very slightly wider, the suture impressed basally 

 and fully two-fifths longer, than the prothorax; abdomen only slightly 

 narrower than the elytra, parallel, with well developed margins, the fourth 

 and fifth tergites equal, the sixth (cf) rectilinearly truncate and but 

 slightly irregular at tip, the lateral processes short, tumid and only 

 slightly projecting posteriorly; middle coxae distinctly separated, the 

 mesosternal process gradually prolonged but rather thick, not finely 

 aciculate, acute at tip, the concave interval between it and the short 

 and broad though evenly angulate metasternum nearly half the femoral 

 thickness. Length 2.7-2.9 mm.; width 0.76-0.83 mm. British Columbia 

 (Metlakatla), Keen. 



In the female the impression in more than basal half of the 

 pronotal median line is feebler than in the male, or subobsolete, 

 but it is of the same nature. This species or the next may prove 

 to be the metlakatlana, of Bernhauer, who compares it with vasta 

 Makl. The elytra here are very much longer than in vasta, judg- 

 ing by Mannerheim's description, but the basal impression of the 

 pronotum seems to recall it. If Dr. Bernhauer can find opportunity
