144 MALACODERMATA. 
11. Colyphus limbatus. 
Colyphus limbatus, Gorham, Trans. Ent. Soc. Lond. 1878, p. 161°. 
Hab. Mexico, Juquila (Bowcard, coll. Sallé)—Vunuzunta ' (Thieme, coll. Oberthiir). 
Scarcely separable from the preceding species, perhaps. In the type and in the 
specimens (which, I think, are identical with it) from Mexico the elytra are very narrowly 
margined with yellow to the apes, and the legs are black. 
12. Colyphus criocerides. (Tab. VIII. fig. 2.) 
Ferrugineus, prothorace macula antica, elytris macula scutellari, alteraque in medio quadrata, tibiis, tarsis 
abdomineque nigris, antennis nigris; clava ferruginea, pectore infuscato. Long. 7 millim. 
Hab. Mexico, Cerro de Plumas (Hége). 
Agreeing closely in size and form with C. signaticollis, and possibly only a remar kable 
variety of that species, but so unlike any of the other varieties as to suggest its really 
being distinct. The head yellow, with only the mouth a little infuscate. The thorax 
and elytra of a bright rusty yellow, with the black marking more distinct than usual. 
The antenne are distinctly clubbed, the club yellow. The specimen figured is the only 
one I have seen. 
13. Colyphus orthopleuridus. 
Derestenus orthopleuridus, Thoms. Mus. Scient. p. 57 *. 
Hab. Mexico, Cordova, Juquila, Orizaba (Sal/é). 
I am at a loss to point out characters by which this can be separated from C. signati- 
collis. There are four specimens in the Sallé collection: the head varies; the thorax 
has the usual frontal spot; the elytra are rather long, immaculate; the legs pale, with 
dark tibie and tarsi. It might be confused with C. guadrilineatus, but that the antenne 
are not serrate and the elytra are subparallel. 
14. Colyphus bicolor. 
Sallea bicolor, Chevr. Rev. et Mag. Zool. 1874, p. 86°. 
Hab. Mexico, Vera Cruz! (Sallé); Oaxaca (H6ge). 
This insect cannot be retained in the genus Sallea, of which S. necrobioides is the 
type; for the labial palpi alone are hatchet-shaped. It comes in very well here. The 
antenne are scarcely clubbed, but are not serrate. 
15. Colyphus collaris. 
Derestenus collaris, Chevy. Mémoire, 1876, p. 12’. 
Hab. Muxtco! (Haag Rutenberg, coll. Chevr.). 
Unseen by me; and I cannot identify it by the description.
