The following six species are of moderately large size, pale color- 

 ation and have the abdominal punctures less dense, larger and in 

 the form of elongate flat asperities; the previously described obliqua, 

 mimetica, virginica, truncatella, saxatilis and nubifer belong to the 

 same group: 



Oxypoda wickhami n. sp. Rather stout and convex, pale ochreo- 

 testaceous, the head piceous and the abdomen blackish, except at the 

 apices of all the segments; surface alutaceous, the abdomen more shining, 

 the punctures very fine, dense and asperulate, the abdominal asperities 

 becoming of uneven size posteriorly and gradually coarser and sparser 

 as usual, the pale vestiture dense and decumbent, less dense and longer 

 on the abdomen, the legs pale; head transverse, more than half as wide 

 as the prothorax, parallel, the eyes large but only slightly convex, with 

 rather fine and dense convex facets, at only a short distance from the 

 base; antennae extending to the base of the prothorax, feebly incrassate, 

 piceous, paler basally, the second joint slightly longer than first or third, 

 which are subequal in length, the fourth about as long as wide, fifth 

 slightly transverse, the tenth nearly one-half wider than long, the last 

 as long as the two preceding, inflated in basal three-fifths but abruptly 

 narrowed and pointed beyond the strong ambient constriction; pro- 

 thorax large, one-half wider than long, widest behind the middle, the 

 sides arcuate, more converging and less so anteriorly, the base evenly 

 rounded, the angles obtuse, distinct, the surface unimpressed; elytra 

 transverse, equal in length to the prothorax, a little narrower than the 

 latter at base but as wide apically, the sides feebly arcuate, the apical 

 sinuses deep; abdomen at base notably narrower than the elytra, very 

 feebly tapering thence to the fifth tergite, which is more than three- 

 fourths as wide as the base and a third longer than the fourth, the margins 

 moderately thick. Length 3.0 mm.; width 0.75 mm. Utah (Provo),

This is one of our largest and most prominent species, recognizable 

 at once by its size, coloration, large eyes, sculpture and other 

 characters. 



Oxypoda recensa n. sp. Nearly as in the preceding in form, coloration 

 and sculpture but smaller, the similarly transverse head inflated slightly 

 basally and with the eyes less developed and at fully one-half of their own 

 length from the base, the antennae blackish, paler and thin basally, 

 more rapidly incrassate distally than in the preceding, fully as long (cf) 

 but short and thinner (9 ), the second and third joints long and slender, 

 each longer than the first and but slightly unequal, fourth quadrate, 

 tenth slightly transverse, shorter in the female, the last a little longer than 

 the two preceding, not inflated basally, more evenly oval and gradually 

 pointed, the ante-median stricture very feeble; prothorax similar but 

 less transverse, less narrowed anteriorly, the sides more evenly arcuate 

 and less so basally than in u'ickhami, the surface sometimes having a very
