STAPHYLINIDA. 793 
Cryptobium equale (p. 513). 
Before the localities given, insert :—-Mrxico, Nuevo Laredo in Tamaulipas, La Noria 
in Sinaloa (Hoge). 
The specimens from La Noria seem quite similar to the typical examples from 
Guatemala, but the two individuals from Nuevo Laredo may possibly be distinct; the 
latter are, however, so very immature that not much value can be attached to the 
differences that are perceptible. 
Cryptobium venustum (p. 516). 
To the Mexican localities given, add :—vVilla Lerdo in Durango (Hége). 
Cryptobium politulum (p. 516). 
To the Mexican locality given, add :—Cuernavaca in Morelos (Hége). 
Cryptobium complectens (p. 517). 
To the Mexican localities given, add :—-Tehuantepec (Hodge). 
The male has a short setigerous line on the third ventral plate, and a circular fovea 
on the following segment; the hind margin of this segment is produced so as to form a 
long rather broad lobe narrowed towards the extremity and there subacuminate. 
Cryptobium crassulum (p. 520). 
To the Mexican locality given, add :—La Noria in Sinaloa, 'Tehuantepec (Hége). 
A good series has now been procured of this insect ; the examples are rather smaller 
and more slender than the two females originally described. The male has two minute 
pencils of hair placed in a small space on the third ventral plate, and a single pencil 
on the following segment; the hind margin of this latter segment is produced so as to 
form a very broad short lobe. 
Cryptobium rostratum (p. 532). 
Before the localities given, insert:—Mexico, Acapulco in Guerrero (Hége). 
The unique example from this subregion differs from the more southern examples in 
being narrower, and possessing a more densely punctured thorax. 
Cryptobium aberrans (p. 533). 
Before the locality given, insert: —Mexico, Acapulco in Guerrero (Hoge).
