726 STAPHYLINIDA. 
Hab. Mexico, Cordova (Sallé); GUATEMALA, El Tumbador, Cerro Zunil, Capetillo, 
Tamahu, Balheu, Cubilguitz (Champion). 
Head rather strongly produced in the middle, the hind angles slightly obtuse; the 
vertex with two rather strong carine, and a longer but less elevated carina between these 
and the outside. Thorax broader than long, greatly constricted behind the middle ; 
with two basal carinee near the middle extending only half of the length towards the 
front, and between these and the sides an elongate carina furcate in front. FElytra 
much longer than the thorax, each with three strongly elevated carine. Hind body 
with a series of seven sharply elevated carine; the latter appearing continuous when 
the segments are contracted, but when they are extended it is seen that the carine 
do not extend to the base of each segment, but that this part is occupied by a series 
of fine crenulations. 
This species was labelled Glyptoma saliwi, Fauv., in Sallé’s collection, and I have 
preserved this specific name; it is very distinct on account of its costate hind body. 
We have received twelve examples; the one from Cubilguitz is a variety of small size, 
with the sculpture of the thorax less coarse.

Hab. Nortu America !, Arizona ?,—Mexico, Teapa ?. 
I have not seen any example of this species. 
8. Thoracophorus truquil. 
Ferrugineus, opacus, minus sculpturatus; prothorace quadrato, medio costis duabus distantibus munito ; elytris 
tenuiter sexcostatis; abdomine fere esculpturato. 
Long. 23 millim. 
Hab. Mexico (Truqui, Sallé, and coll. Sharp). 
Head very short and broad, only slightly rounded in front, the disc with two short 
longitudinal elevations, the antennal tubercles strongly elevated. ‘Thorax transversely 
quadrate, quite straight in front; the sides erenulate and quite straight nearly to the 
base, then a little narrowed; hind angles rectangular; on the middle are two coste, 
and near each side a finer one, the coste widely separated and the space between them 
uneven though not sculptured. Elytra slightly longer than the thorax; finely and 
regularly costate, otherwise not sculptured, dull. Hind body very feebly sculptured at 
the base only, the apex slightly shining. 
Of this species I have seen only the two examples collected by Truqui; I have 
retained the name proposed for it in Sallé’s collection.
