PSEUDOCYPHUS. 
Pseudocyphus, Schaeffer, Bull. Brooklyn Instit. i. p. 179 (1905). 
Rostrum very stout, not longer than the head, not dilated anteriorly ; the upper portion sulcate, narrowing 
forwards, sharply produced on each side between the points of insertion of the antenne, and excavate 
and foveate in the middle; the nasal plate depressed, long, triangular, squamose, and emarginate in 
front; the gene triangularly excised ; the scrobes in great part visible from above, curved, sublateral, 
converging forwards, and not extending below the eyes. Eyes large, oval (as seen in profile), not 
strictly lateral. Antennal scape curved, flattened, more or less dilated or clavate. Prothorax short, 
bisinuate at the base, truncate in front. Scutellum well developed. LElytra subtriangular (3) or 
oblong (2), 10-striate, the outer strie entire, the humeri prominent. Tibie unarmed at the inner 
apical angle in both sexes; posterior pair laminate and squamose at the apex, the articular surface 
glabrous and ascending. Body winged, densely squamose. 
Under this genus are placed various moderate-sized Mexican and Guatemalan forms 
nearly related to the S.-American Platyomus mutabilis, diane, &c., all of which differ 
from the type of Platyomus (Cyphus cultricollis, Germ.) in having large, oval, moderately 
prominent eyes, an apically dilated scape, a subcylindrical or subconical prothorax, 
non-tuberculate elytra, &c. ‘The type of Pseudocyphus, P. fleaicaulis, Schaeff., from 
Brownsville, Texas, for specimens of which we are indebted to Mr. Wickham and the 
author (Tab. XIII. fige. 7, 7a, 3), has the head relatively broader, the antenne 
stouter, and the outer joints of the funiculus more transverse than in the Central- 
American species, but these differences are insufficient for generic separation *. 
* The allied genus Chamelops (type C. munita, Kirsch, from Colombia) has the scape strongly curved, 
slender at the base, and greatly dilated outwards, the funiculus slender, the elytra strongly lobed at the base, 
the legs very hairy, &c. Temnoscapus fissirostris, Chevr., from Bogota (the type of which I have seen), is 
another allied form; it superficially resembles the female of Stetrarrhinus conicollis, differing from that insect 
in the short antenne, with apically dilated curved scape, the not strictly lateral eyes, the non-descending 
scrobes, &c.
