STAPHYLINID.E 133 



with very feebly diverging and nearly straight sides, at base very slightly 

 wider, the suture nearly two-fifths longer, than the prothorax, the apices 

 not at all sinuate externally ; abdomen parallel, with straight sides, slightly 

 narrower than the elytra, the fifth tergite notably longer than the fourth, 

 the sixth ventral in the type with arcuately converging sides, the apex 

 arcuato-truncate; middle coxae contiguous, the metasternum behind 

 them very short and broadly angulate. Length 3.0 mm.; width 0.85 

 mm. Manitoba (Aweme), Norman Criddle. 



A fine species, recognizable by its long antennae, fine sculpture, 

 coloration and other features. 



Metaxya prognata n. sp. Large, narrower, subparallel, moderately 

 convex, shining, minutely and not densely punctured, the micro-reticu- 

 lation small and very feeble, close and transversely substrigilate toward 

 the turgitical apices; color piceous, the elytra a little paler, the abdomen 

 blackish, becoming largely very pale at apex, the pubescence rather 

 coarse and not very short, pale; head slightly transverse, nearly four- 

 fifths as wide as the prothorax, parallel and very feebly arcuate at the 

 sides, the eyes scarcely prominent and at evidently more than their own 

 length from the base: antennae blackish, long, very gradually rather heavy 

 outwardly, the second joint as long as the first but much more slender, 

 the third distinctly shorter than the second, one-half longer than the 

 fourth, which is moderately elongate and equal to the fifth, six to ten 

 more obtrapezoidal and passing from as long as wide to evidently wider 

 than long, the last not very acute at tip and not quite as long as the two 

 preceding; prothorax only about a fifth wider than long, subparallel and 

 feebly arcuate at the sides, the latter perhaps more nearly straight basally, 

 the basal angles very obtuse and blunt, the median line very feebly 

 impressed almost throughout and also with a very small ante-scutellar 

 impression; elytra moderate, not long, at base a fifth or sixth wider, the 

 suture not at all longer, than the prothorax but equal in length to the 

 latter; abdomen parallel, with straight sides, slightly narrower than the 

 elytra, long, the fifth tergite but little longer than the fourth, the punc- 

 tures minute and not very close; middle coxae contiguous or virtually so, 

 the metasternum very short and broadly angulate. Length 3.4 mm.; 

 width 0.8 mm. British Columbia (Metlakatla), Keen. 



Differs from the preceding in its more slender form, stouter an- 

 tennas, narrower prothorax, shorter elytra and much less close 

 though equally fine punctulation. The sixth ventral plate in the 

 type is large, with the sides rapidly converging and but slightly 

 arcuate, the apex evenly but relatively somewhat narrowly rounded. 



Metaxya badeola n. sp. Moderately slender and convex, shining, 

 dark piceo-rufous, the head and abdomen black, the latter barely at all 

 paler at tip, the legs piceous though in part paler; punctures fine, well 

 separated, rather sparse on the abdomen, the minute sculpture very 

 feeble; pubescence rather long and somewhat coarse; head fully as long
