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. 
4. Pseudocyphus zebra, sp.n. (Tab. XIII. fig. 12, 2.) 
Platyomus zebra, Pilate, in litt.’ 
Oblong, rather narrow (3 ), broader (2), black; variegate with a dense clothing of cinereous and blackish 
(or brown) scales ; the latter condensed into three vitta on the prothorax and various markings on the 
elytra—a large subquadrate patch on the outer part of the disc just below the base, another patch lower 
down near the suture, an angulate, curved, oblique post-median fascia, and a narrower interrupted fascia 
or transverse spot near the apex; the upper surface also set with minute, widely scattered, decumbent 
hairs. Head and rostrum rugulosely punctate and narrowly sulcate ; antennal scape about reaching the 
posterior margin of the eye in both sexes, rapidiy widening outwards in g, narrower in 9 ; eyes very 
large, moderately convex. Prothorax transverse, subcylindrical, bisinuate at the base, closely punctate 
and obsoletely canaliculate. Elytra subtriangular (¢), subparallel to about the middle (¢ ), strongly 
bisinuate at the base, with rows of coarse scattered punctures, the interstices more or less convex and 
rugulosely punctate. 
Length 53-74, breadth 2-34 millim. (¢ 9.) 
Hab. Mexico, Yucatan (Pilate+, in Mus. Brit.), Campeche (Sallé), Temax (Gaumer). 
Nine specimens, one with the dark markings faint, but clearly traceable. Differs 
from P. macroscapus in having larger eyes, a shorter and more strongly clavate 
antennal scape, more prominent humeri (the elytra being subtriangular in the male), 
and widely separated, coarser, seriate punctures on the elytra, these being more distant 
one from another than in P. chrysopus. 
5. Pseudocyphus chrysopus, sp. n. (Tab. XIII. figg. 13, ¢; 14, 2, var.) 
Platyomus chrysopus, Chevr. in litt.’. 
Platyomus auripes, Jekel, in litt.’. 
Oblong, narrow (¢ ), broad (@), black ; densely clothed with green scales, the scales on the head, antennal 
scape, anterior half of prothorax, and legs usually more or less cupreous, the prothorax often with a 
median vitta, and the elytra with a spot on the third interstice beyond the middle (and sometimes one 
or two others on the fifth and seventh in a line with it), black ; the surface also set with short decumbent 
hairs, which are seriately arranged down each elytral interstice. Head and rostrum narrowly sulcate 
and rugulosely punctate; antennal scape rapidly widening outwards, reaching to a little beyond the eyes, 
slightly narrower in 9, setose; eyes very large, moderately convex. Prothorax transverse, bisinuate at 
the base, rugulosely punctate. Elytra subtriangular ( ¢), parallel-sided to about the middle (@ ), strongly 
bisinuate at the base, the humeri prominent; with rows of rather coarse somewhat widely separated 
punctures, the interstices convex and rugulosely punctate. 
Var. a. The elytra with the base and a transverse post-median fascia (the latter including several blackish 
spots) cupreous. 
Var. 6. The prothorax with one or three vitte on the disc, and the elytra with the suture, a large oblique or 
subquadrate patch on the outer part of the disc below the base, a common transverse patch before the 
middle, a transverse angulate post-median fascia, and another fascia near the apex, carneous, cupreous, 
fuscous, or black, the rest of the scales varying in colour from green to cinereous, those on the legs and 
antennal scape sometimes cupreous. 
Length 62-10, breadth 23-4 millim. (d 9.)
