STAPHYLINIDZ. 791 
Kight specimens. The example from La Noria is in a very bad state of preservation, 
but apparently is a pallid variety of this species. 
DIOCHUS (p. 466). 
1 (a). Diochus longicornis. 
Diochus longicornis, Sharp, Trans. Ent. Soc. Lond. 1876, p. 184’. 
Hab. Mexico, 'Teapa in Tabasco (Hége).—Soura Amurica, Amazons valley !. 
The unique example we have received from Herr Hoge may, perhaps, prove not to 
belong to this species, with which, however, it agrees in the elongate antenne, and 
differs only in slight details. 
XANTHOLINUS (p. 475). 
Xantholinus resectus (p. 480). 
To the locality Mexico, add :—near the city (Hége). 
Xantholinus difficilis (p. 482). 
Before the locality given, insert :—Mexico, Salazar (/égqe). 
I am not quite sure that the solitary example now obtained is really conspecific with 
the unique Guatemalan type, as it is both smaller and more slender. 
SOMOLEPTUS (p. 494). 
Somoleptus bicolor (p. 495). 
Before the locality given, insert :—-Mexico, near the city, Zacualtipan (//6ge). 
SAUROHYPNUS (p. 501). 
2. Saurohypnus nigerrimus. 
_Elongatus, angustulus, nigerrimus, nitidus ; antennis extrorsum tarsisque rufo-obscuris ; capite elytrisque fortiter 
punctatis; prothorace tantum versus angulos anteriores et ad Jatera punctato. 
Gong. 16 millim. 
Hab. Mexico, Jalapa (//oge). 
Head slightly broader than the thorax, shining black, coarsely punctured, the 
punctures on the middle distant; antennal grooves elongate. Thorax elongate, 
narrowed towards the base, shining black, with coarse punctuation along the side 
margins and front, and with six or seven other punctures placed irregularly near the 
side in front. Scutellum bearing six large punctures. Elytra about as long as thorax, 
regularly, coarsely, and distantly punctured. Hind body finely and sparingly punctured, 
shining black. Four examples. 
This insect has the antenne rather more widely separated than they are in the
