516 STAPHYLINIDA. 
22. Cryptobium venustum. 
Subdepressum, rufescens, nitidum; capite nigro, subquadrato, crebrius fortiter punctato, subopaco; elytris 
crebre fortiter, basin versus subseriatim, punctatis, nitidioribus; abdomine piceo, apice rufo; pedibus 
testaceis. 
Long. 10 millim. 
Hab. Mxxico, Oaxaca, Jalapa (Hége). 
The head is densely, coarsely and subobsoletely punctured behind, on the middle 
sparingly and definitely ; the middle is a little shining, the impunctate portion between 
the antennal tubercles being dull. The thorax is red, shining, coarsely and closely 
punctured, at the base more sparingly and with a broad impunctate space along the 
middle. The elytra are about one third longer than the thorax, red, shining, rather 
coarsely, deeply, and closely but not densely punctate, the punctuation towards the 
apex much finer but quite definite. The male has a moderately broad setigerous space 
on the third ventral segment, and on the fourth a large circular setigerous fovea; this 
segment also is produced to form a broad short lobe. The female has no positive 
sexual marks. 
The individuals of this species are similar in size and form to C. similipenne, but the 
two are readily distinguished by the coloration and differences in the details of the 
punctuation. 
23. Cryptobium coloratum. 
Subdepressum, sat latum, nitidum, piceo-rufum, antennis rufis, pedibus testaceis; capite subquadrato, opaco, 
crebrius fortiter punctato; prothorace crebre fortiter punctato, medio sat late longitudinaliter levigato ; 
elytris nitidioribus, rufis, sat fortiter haud dense punctatis; abdomine apice dilutiore. 
Long. 11 millim. 
Hab. Guatemata (Sallé). 
The unique example of this species is very closely allied to C. venustum, but is a 
rather larger and broader insect, with rather coarser punctuation on the elytra, and 
different characters in the male; the third segment in this sex has a somewhat narrow 
transverse setigerous space, and the next a small circular pubescent spot; this segment, 
moreover, is produced so as to form a rather long lobe, broad at the base but much 
attenuate behind. 
24. Cryptobium politulum. 
Subdepressum, nitidum, piceum ; antennis rufis, pedibus testaceis ; capite subquadrato, crebre fortiter punctato ; 
prothorace crebre fortiter punctato, medio sat late longitudinaliter levigato; elytris crebre fortiter pro- 
fundeque subseriatim punctatis. 
Long. 94 millim. 
Hab. Mexico, Uruapan (Lohr, coll. Sharp). 
This species is very closely allied to C. venustum, but is, I have no doubt, distinct, as, in 
addition to its more dilute and uniform colour, it is rather smaller, has a more shining,
