PSEUDOCYPHUS. 285 
from the somewhat prominent humeri, the base strongly bisinuate; finely punctate-striate, the interstices 
moderately convex and rugulose. First ventral segment slightly depressed down the middle. 
9. Var. a. The scales with a slight greenish tinge; the elytra with a small spot on the shoulder, two others 
on the fourth interstice below the base, an angulate, rather broad fascia beyond the middle, and a spot 
near the apex, black, the interstices each with a row of minute scattered hairs. 
©. Var. 6. The scales whitish; the elytra with two transverse fasciz on the outer half of the dise—one, 
narrow, just below the base, the other, angulate, beyond the middle,—a patch near the apex, and 
a common, narrow, transverse mark just behind the scutellum, black, the interstices with a row of 
minute hairs. [Fig. 10.] 
Length 7-84, breadth 24-34 millim. (¢ 9.) 
Hab. Mexico, Playa Vicente in Vera Cruz [type], Tapachula in Chiapas [var. a] 
(Hoge), Oaxaca [var. 8] (Hegewisch, in coll. Sommer). 
Two males and two females, the three forms evidently belonging to one variable 
insect (the var. 8 kindly lent us by Mr. Janson), the females having a slightly shorter 
antennal scape than the males and a line of very minute hairs down each elytral 
interstice. Compared with P. macroscapus the present species may be known by the 
more strongly sinuate base of the elytra, the outwardly-dilated shorter scape of the 
male antenna, and the different markings *. 
8. Pseudocyphus macroscapus, sp.n. (Tab. XIII. fig. 11, 3.) 
Oblong, narrow (¢), broader (2), black; variegate with a dense clothing of whitish (or cinereous) and 
blackish (or brown) scales, the latter sometimes predominating and leaving two vittee on the disc of the 
prothorax, a long streak at the base of the third elytral interstice, two angulated oblique fasciz 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 fascize 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 ure 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 3, broader in 9, feebly bisinuate at the base; rather finely punctate- 
striate, the interstices rngulose and somewhat convex. First ventral segment feebly hollowed down the 
middle. 
Length 5-74, breadth 2-3 millim. (¢ 2.) 
Hab. Guatemata (Sallé), Zapote, Capetillo, Duefias, San Gerdnimo (Champion), 
Chimaltenango (Conradt). 
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 fasciz and the prothoracic vitte are always distinctly 
visible. The scape of the antenne is widened from near the base, and it is considerably 
elongated in the male. ‘The sete are sometimes extremely short, and the light scales 
* An undescribed insect (Q) in the British Museum labelled “ Platyomus gratiosus, Jekel, Brazil,” is 
extremely like P. nigroguttatus, but it has the antennal scape more slender and the scattered black spots on 
the elytra differently arranged.
