Casey — Observations on the Staphylinidae, 129 



Body less stout, the head and prothorax nearly as in Xenoch0.ra but with the 

 basal angles of the latter more rounded; elytra evenly arcuato-truncate 

 at tip, not at all sinuate externally; abdomen more coarsely and only 

 moderately closely sculptured, with the first tergite alone distinctly 

 impressed. South Africa *Notiochara 



7 — Anterior and middle tibiae finely spinulose or setose, the former elong- 



ate and not dilated 8 



Anterior and middle tibiae very coarsely spinulose externally, the former 

 much shorter than usual, dilated and somewhat arcuate 10 



8 — Fourth joint of the maxillary palpi conical, the third elonizate and mod- 



erately slender as usual. Body stout^ parallel; mesoslernal process 

 slightly abbreviated, narrow, gi-adually tapering to the narrow ernarg- 

 inate apex, which attains the acutely angular apex of the pronounced 

 metasternal projection; carina very fine, confined to the anterior half of 

 themesosternum; head rather large, but little narrowed behind the mod- 

 erate and somewhat prominent eyes to the broad neck, the front be- 

 tween the eyes very broadly angular; antennae relatively short and very 

 stout; prothorax with unusually distinct basal angles; elytra truncate 

 or very feebly and broadly subsinuate externally at tip; abdomen finely, 

 very closely punctured, the first three tergites broadly, deeply and 

 subequally concave at base, the others not impressed; hind tarsi very 

 long, fully equaling the tibiae in length, gradually tapering from base 

 to apex, the basal joint longer than the next two combined; femora and 



tibiae densely fulvo-setulose. Western America Oreocliara 



Fourth joint of the maxillary palpi aciculate 9 



9 — Third palpal joint unusually short, broad at apex, obcouical, not twice 



as long as wide, the fourth rapidly enlarged toward base; mesosternal 

 process acutely pointed. Form narrower, more depressed and parallel; 

 mesosternal process very narrow, gradually narrowed nearly to the apex, 

 then more strongly and arcuately so to the actual tip, which nearly 

 extends to the end of the coxae and fully attains the broadly but sharply 

 angulate apex of the metasternum, the carina fine, confined to anterior 

 two- fifths of the mesosternum; head large, the sides rapidly and arcu- 

 ately converging behind the well developed eyes, the front between 

 the latter very broadly parabolic; antennae well developed; prothorax 

 with the basal angles broadly obtuse but distinct, the disk uniformly 

 punctured: elytra with the apex narrowly and feebly sinuate at the 

 sides; abdomen with the first four tergites broadly and roundly impressed 

 at base, gradually less strongly so, the irrpressious deep on the basal 

 plates, feeble but distinct on the fourth and all much more finely 

 though more closely punctate than the remainder of the surface ; hind 

 tarsi rather shorter than the tibiae, with the first joint only as long as 

 the next two combined and scarcly as long as the fifth, the tibiae more 

 sparsely setulose than in Oreochara. Pacific Coast of America. 



Calochara 

 Third palpal joint elongate, moderately slender, the four^.h slender and 

 never more than feebly tapering throughout. Form generally simi- 

 lar to that of Calochara, less stout than in Aleochara and Oreochara, 

 rather convex; mesosternal process variable in width bnt long, always 

 truncate or sinuate at tip, generally nearly attaining the tip of the
