Catey — Observations on the Staphylinidae. 311 



species is given in the catalogue of Heyden, Reitter and 

 Weise as European, with several European synomyms ap- 

 pended, and, as it is apparently a smaller species than that 

 indicated by Erichson in his description, I have concluded to 

 regard it as distinct. 



Ifaslrema Csy. 



This genua is allied rather closely to Phloeopora but 

 differs in its much larger and thicker antennae, with more 

 obtuse terminal joint, among other characters. The follow- 

 ing species is very distinct in general appearance : — 



Slender, parallel, strongly convex, polished, dark rnfo-castaneons, the elytra 

 slightly paler rafoas, the legs brownish- flavate, the antennae fascoas, 

 paler toward base; integuments very faintly micro-reticulate throagh- 

 out; pubescence flue, rather sparse, decumbent; head fully as long as 

 wide, finely, sparsely punctulate, the eyes rather small ; antennae longer 

 than the head and prothorax, very thick distally, the outer joints closely 

 joined and strongly transverse, the last but little longer than wide, very 

 obtusely rounded at tip; prothorax distinctly wider than the head, only 

 slightly wider than long, parallel, the sides evenly arcuate almost 

 throughout, the surface even, not impressed at any point, finely, sparse- 

 ly punctulate; elytra about a fifth wider and a fourth longer than the 

 prothorax, finely and closely but more distinctly punctate, the humeri 

 scarcely at all exposed at base, parallel, the sides evenly arcuate; ab- 

 domen distinctly narrower than the elytra, parallel and straight at the 

 sides, very minutely, rather sparsely punctulate, the first three tergites 

 strongly and equally impressed and somewhat more coarsely punctate 

 at base, the fourth wholly without trace of basal impression. Length 

 2.25 mm.; width 0.48 mm. Iowa (Iowa City), — H. F, Wickham. 



inqaillna n. sp. 



Differs greatly from humilis and paiinceps in its polished 

 and sparsely punctulate integuments, but apparently con- 

 generic; it occurs in the nests of a rather large brown ant. 



Oxypoda Mann. 



The following species are additional to those previously 

 published by the writer (Ann. N. Y. Acad. Sci., VII, pp. 

 290-300). 



Last antennal joint moderate in size, not longer than the two preceding 

 combined 2
