Pseudocyphus macroscapus Champion 1911

Oblong, narrow (♂), broader (♀), black; variegate with a dense clothing of whitish (or cinereous) and blackish (or brown) scales, the latter sometimes predominating and leaving two vittæ on the disc of the prothorax, a long streak at the base of the third elytral interstice, two angulated oblique fasciæ on the disc, and a patch at the apex, pale—in lighter individuals the dark markings are reduced to three faint stripes on the prothorax, two or three interrupted oblique fasciæ on the elytra, an interrupted sutural stripe, and an oblong spot on the third interstice below the base; the upper surface also set with short, semierect, bristly hairs, which are seriately arranged down each interstice, the lower surface uniformly cinereo-squamose. Head and rostrum rugulosely punctate and narrowly sulcate; eyes large, moderately convex; antennal scape widened from near the base, becoming a little broader at the apex, reaching to beyond the front of the prothorax in ♂, and to the posterior margin of the eyes in ♀. Prothorax transverse, somewhat rounded at the sides, closely punctate and feebly canaliculate. Elytra subparallel to about the middle in ♂, broader in ♀, feebly bisinuate at the base; rather finely punctate-striate, the interstices rugulose and somewhat convex. First ventral segment feebly hollowed down the middle.
 
Length 5—7½, breadth 2—3 millim. (♂ ♀.)

Found in numbers on the Pacific slope of Guatemala and singly in Baja Vera Paz. The specimens vary in colour, according to the predominance of the light or dark scales, but the oblique elytral fasciæ and the prothoracic vittæ are always distinctly visible. The scape of the antennæ is widened from near the base, and it is considerably elongated in the male. The setæ are sometimes extremely short, and the light scales occasionally have a faint greenish or cupreous tinge. The Texan P. flexicaulis is somewhat like P. macroscapus, but it has a broader head and prothorax, differently marked elytra, &c.
