Additional Miscellaneous Aleocharinae. 



While the present paper was waiting for the press I took 

 occasion to draw up descriptions of some more especially 

 interesting species, which may be advantageously published 

 at the present time as follows : — 



Aleocharini. 

 Ocalea Er. 



Form rather stoat, convex, strongly shining, dark testaceous, the elytra 

 shaded somewhat darker externally toward apex and narrowly along the 

 suture, the head and abdomen piceous-black; legs pale, the antennae 

 blackish, gradually paler toward base; surface only very obsoletely 

 micro-reticulate, the elytra more distinctly, the abdomen excessively 

 minutely strigilate in transverse wavy lines; head parallel at the sides , 

 obliquely constricted at base, feebly and rather sparsely punctate, the 

 antennae long, gradually and moderately incrassate distally, the tenth 

 joint not quite as long as wide, the eleventh scarcely as long as the two 

 preceding combined; prothorax large, fully one-half wider than the 

 head and a third wider than long, the sides broadly subangulate at 

 about the middle, thence strongly converging to the apex, which is 

 much narrower than the base; surface evenly convex, finely, sparsely 

 punctate, with a small transverse discal impression before the scutellum ; 

 elytra large, only just visibly wider and nearly one-half longer than the 

 prothorax, finely, closely and asperulately punctured; abdomen at base 

 somewhat narrower than the elytra, gradually tapering thence to 

 the apex, finely, sparsely punctate throughout, the vestiture rather long 

 but sparse, elsewhere short; mesosternal process extending to apical 

 fourth of the coxae, extremely acute at tip and free, the metasternum 

 scarcely at all entering between the coxae, obtusely angulate, the long 

 intermediate isthmus narrowly convex transversely. Length 3.4 mm.; 

 width 0.88 mm. California (Siskiyou Co.) grandicollis n. sp. 



Form and coloration nearly as in the preceding, the elytra scarcely percep- 

 tibly shaded darker externally but more distinctly in the region of the 

 scutellum, quite as convex and polished, the micro-reticulation almost 

 wholly obsolete, even on the elytra, the strigilation of the abdomen 

 coarser but very nearly obsolete ; vestiture sparse and inconspicuous ; 

 head larger but similar in form, finely, sparsely punctate, the antennae 

 rath«r shorter, extending barely to the middle of the elytra but other- 

 wise nearly similar, the eleventh joint more pointed and as long as the 

 two preceding combined; prothorax relatively smaller, not subangu- 

 late at the sides, the latter subparallel and broadly, evenly arcuate, the 

 basal angles more obtusely rounded and less distinct, only about a
