48 MEMOIRS ON THE COLEOPTERA. 



Oxypoda scaeva n. sp. Moderately stout and rather dull, dark piceous- 

 brown throughout, the legs pale piceo-rlavate; punctures very fine and 

 scarcely at all asperate, well separated, similar but closer on the abdomen, 

 the vestiture not very abundant or conspicuous, palish; head smaller 

 than in the preceding, less transverse and more parallel, scarcely three- 

 fifths as wide as the prothorax, the eyes smaller; antennae shorter, slightly 

 stouter and more evidently incrassate distally, blackish, the second joint 

 distinctly longer than the first or third, the latter two equal, fourth not 

 quite as long as wide, outer joints evidently wider than long, the ninth 

 shorter than the tenth, the eleventh long, slender, cylindric, obtusely 

 pointed at tip, longer than the two preceding, constricted feebly at apical 

 third; prothorax nearly as in the preceding, except that the feebly 

 converging sides are very much less arcuate and the feeble, transverse 

 and somewhat binary ante-scutellar impression more evident; elytra 

 large and similar but evidently a little shorter than wide, at base fully 

 as wide as the prothorax, at apex wider, the suture less impressed basally 

 and about two-fifths longer than the pronotum, the apical sinuses deep, 

 somewhat narrow; abdomen much smaller than in sejuncta, narrower, at 

 base not quite as wide as the prothorax, thence feebly and evenly tapering, 

 with straight sides and thin margins, to the fifth tergite, which is four- 

 fifths as wide as the first. Length 2.0 mm.; width 0.62 mm. Oregon 

 (The Dalles), Wickham. 



To be separated with ease from the preceding by its smaller head, 

 heavier antennae, less rounded sides of the prothorax and by the 

 smaller abdomen with straighter sides. 



Oxypoda saturata n. sp. .Stout, somewhat fusoid and convex, rather 

 shining, piceous-black, the elytra distinctly paler, infumate postero- 

 laterally and on the suture basally, the legs piceous, paler distally; 

 punctures fine, nearly as in the preceding throughout but stronger, closer 

 and more asperate, except on the abdomen, the vestiture rather coarse 

 and palish but not dense; head almost two-thirds as wide as the pro- 

 thorax, transverse, the eyes large, rather convex, at about half their 

 length from the base, the antennse blackish throughout, somewhat slender, 

 feebly incrassate distally, the first joint as long as the second and thicker, 

 third shorter and more obconic, the fourth nearly as long as wide, obtrap- 

 ezoidal, the outer joints of the same form, moderately transverse, the 

 ninth shorter than the tenth, the last not longer than the two preceding, 

 gradually pointed distally; prothorax larger than in the two preceding 

 though nearly similar in form, except that the sides are more converging 

 from base to apex, subevenly and distinctly arcuate, the surface with a 

 rather large and rounded ante-scutellar pit; elytra large though still 

 shorter and more transverse than in the preceding, at base fully as wide 

 as the prothorax, the sides rather strongly diverging from the base, the 

 suture a third longer than the prothorax, the sinuses deep; abdomen not 

 quite as wide as the prothorax, much narrower than the elytra, parallel, 

 scarcely at all narrowed apically, with nearly straight and moderately 

 thin margins, the fifth tergite barely a third longer than the fourth;
