Casey — Observations on the Staphylinidae. 135 



the latter slender and normal; antennae stout, somewhat longer than 

 the head and prothorax, gradually and strongly incrassate distally, the 

 outer joints less than twice as wide as Ions, the second and third 

 moderately elongite, equal, the fourth obtraptzoidal, as long as the 

 fifth but much narrower; prothorax three -fifths wider than long, 

 strongly narrowed from base to apex, with the sides strongly and evenly 

 arcuate, the base evenly arcuate; punctures like those of the head, very 

 minute and rather sparse, evenly distributed; elytra short, but little 

 wider than the prothorax, the sides much shorter than those of the lat- 

 ter, the suture barely three- fifths as long as the median lice; punc- 

 tures small but strong, close-set and very strongly asperate; abdomen 

 at base almost as wide as the elytra, gradually but only very feebly nar- 

 rowed thence to tip, finely but strongly, asperately and rather closely 

 punctured, sparsely so toward tip; hind tarsi very nearly as long as the 

 tibiae, with the bas^^al joint longer than the next two combined and 

 much longer than the fifth; mesosternal ridge feebly elevated, the finely 

 cariniform summit even thrcushout, setose toward tip. Length 3.6 



ram. ; width 1.2 mm. ■ South Africa (Wellington) snbaspera n. sp. 



Form less stout, parallel, equally convex, deep black throughout; antennae 

 black, faintly piceous at base, the legs paler, rufo-piceous; pubescence 

 very short, dark and inconspicuous; head and antennae nearly as in 

 subaspera, the latter somewhat shorter and more incrassate, not as long 

 as the head and prothorax, the penultimate joint very nearly twice as 

 wide as long; prothorax minutely, sparsely and evenly punctulat^ trans- 

 verse, nearly as in the preceding but rather less narrowed from base to 

 apex, with more arcuate sides; elytra not at all wider though shorter 

 than the prothorax, the suture nearly two-thirds as long as the median 

 line, the punctures fine, less close-set but almost as strongly asperate; 

 abdomen as wide as the elytra, arcuately narrowing in apical half, finely, 

 asperately and less closely punctate; hind tarsi as long as the tibiae; 

 mesosternal ridge low, the summit finely and strongly cariniform 

 anteriorly but broadening into a transversely rounded polished surface 

 posteriorly with setae toward tip as usual. Length 2.9 mm.; width 0.9

Ceranota Steph. — The characters of the description given 

 above are drawn from a specimen kindly given me by Mr. 

 A. Fauvel, under the name erytJiroptera Grav. It is a highly 

 specialized genus, remarkable not only in the broad turgitical 

 impressions, but in the very large shallow^ excavation occasion- 

 ally observable at the bases of the second and third ventrals, 

 which may be sexual, and the male tubercles of the first one 

 or two and the fifth dorsal plates. In the long and well 

 developed, externally sinuate elytra and other characters, 

 such as the feebly inflexed hypomera and conformation of the 

 intermesocoxal parts, it is an evident ally of Rheochara, and
