STAPHYLINID^E. 37 



In the following ten species the general facies is nearly as in the 

 wickhami-congesta series, but the coloration is more frequently 

 dark, and they differ radically besides in having the abdominal 

 punctures much more minute, denser and never in the form of 

 elongate asperities; the previously described glenorce belongs to 

 this series: 



Oxypoda hiemalis n. sp. Rather small, slender and convex, pale 

 ochreo-testaceous, the elytra scarcely darker, the head pale piceous, 

 the abdomen brown, feebly infumate except basally and at apex; punc- 

 tures throughout very minute and close, the lustre dull, more shining on 

 the anterior parts, the pale vestiture close, only moderately short; head 

 but little more than half as wide as the prothorax, wider than long, the 

 eyes coarsely faceted, not prominent, at nearly their own length from the 

 base; antennae pale piceo-testaceous, short, gradually moderately in- 

 crassate, the second joint as long as the next two combined, fourth as 

 long as wide, tenth more than one-half wider than long, the last not in- 

 flated, rather longer than the two preceding, obtusely ogival at tip, the 

 constriction vestigial and on the inner side only; prothorax large, convex, 

 one-half wider than long, much narrowed at apex, with evenly arcuate 

 sides, somewhat wider behind the middle than at base, the latter only 

 feebly arcuate; elytra short and transverse, evidently narrower than the 

 prothorax. the suture not more than three-fourths as long as the latter, 

 the apical sinuses distinct; abdomen almost as wide as the elytra, parallel, 

 narrowing slightly toward tip, the margins rather thin, the fifth tergite 

 one-half longer than the fourth; basal joint of the hind tarsi longer than 

 the next two combined. Length 1.8 mm.; width 0.45 mm. Canada 

 (Ottawa), Harrington. 



Distinct in general form and coloration, in its short elytra, large 

 prothorax and other features. 



Oxypoda elusa n. sp. General form as in hiemalis, the pale parts 

 darker brown, the abdomen brown-black, paler apically; punctures fine, 

 only moderately close, asperate, especially on the elytra, extremely fine 

 and dense throughout the abdomen, the vestiture pale, short, close; 

 head slightly more than half as wide as the prothorax, the obliquely 

 oval eyes feebly convex, at less than their own length from the base, 

 the facets rather small and not in mutual contact; antennae not so short 

 and rather heavier than in the preceding, blackish, pale basally, the second 

 joint longer than the third but not as long as the next two, tenth less 

 transverse, the last larger, almost as long as the preceding three, con- 

 stricted beyond the middle, the basal part inflated and thicker than the 

 preceding joints; prothorax nearly as in the preceding though relatively 

 not so large and a little shorter; elytra not so short, slightly narrower than 

 the prothorax, parallel, the suture four-fifths as long as the pronotum, 

 the apical sinuses distinct; abdomen at base as wide as the elytra, thence 

 very feebly tapering and with nearly straight sides to the fifth tergite,
