STAPHYLINIDA. 799 
has behind a broad depressed space, the anterior margin of which is curvate, the hind 
margin being very feebly emarginate. Two examples. 
This is not closely allied to any other of our species. In Casey’s arrangement of 
the North-American Steni it should apparently come near S. animatus. 
4(s). Stenus idoneus. 
Niger, pube erecta sat dense vestitus, dense fortiter punctatus, sat nitidus, pedibus piceis, antennarum articulo 
basali flavescente ; fronte obsolete bisulcata, haud excavata; prothorace canaliculato; abdominis segmentis 
ad baseos quadricuspidatis. 
Long. 4 millim. 
Hab. Mexico, near the city, Toluca (Hége). 
Head rather small, scarcely broader than the thorax, broadly and very indistinctly 
depressed on either side near the eye. Thorax longer than broad, densely rugose- 
punctate, distinctly canaliculate along the middle.  Elytra considerably broader, 
and a little longer, than the thorax; densely rugose-punctate, but shining, and the 
sculpture not at all tortuous. Hind body rather sparingly punctured. Male unknown. 
Two specimens. 
This species is not closely allied to any other known in our region, nor does it 
appear to be closely allied to any of the North-American Sten described and tabulated 
by Casey. The erect pubescence is one of its most striking peculiarities, and in the 
typical example from Toluca the pubescence is flavescent; the second example from 
the City of Mexico is much abraded, and the pubescence is paler; this latter example, 
moreover, has the legs black, so that it possibly may be a closely allied distinct species. 
Stenus eremitus (p. 655). 
To the Mexican locality given, add :—Tlacotalpam (Hége). 
Stenus laceratus (p. 658). 
To the Mexican localities given, add :—Mexico city, Huitzo in Oaxaca, Cordova, 
San Juan Bautista in Tabasco, Tehuantepec (Hége). 
The small series shows a good deal of variation in the punctuation of the thorax and 
elytra, the punctuation being much scantier in the slender examples from Tehuantepec. 
Stenus godmani (p. 662). 
Mr. Flohr informs me that this species (and probably others of this peculiar group) 
is arboreal in its habits; he has recently obtained it by beating small oaks at Jalapa
