488 RHYNCHOPHORA. 
seriate-punctate elytra, and short, stout legs, the vestiture coarse and brown, the elytra 
transversely gibbous and with a faint blackish fascia at the commencement of the apical 
declivity. ‘The more prominent humeri separate P. laticollis from the genus Perieres. 
4. Pseudomopsis nigrosignatus, sp. n. 
Subovate, shining, black, the elytra rufo-piceous, the antenne ferruginous ; thickly clothed with intermixed 
ochreous, brownish, and whitish scales, the light-coloured scales condensed on the elytra into a faint, 
broad, oblique, humeral streak and a common, subapical, angulate fascia ; the elytra also with a small, 
transverse, rhomboidal, black patch on the suture at about one-third from the apex, and a minute black 
spot between this and the tip, the alternate interstices with a scattered series of small slightly raised 
scales. Head densely punctate, the eyes well-separated ; rostrum rugulose and squamose at the base, and 
sparsely, very minutely punctate thence to the tip. Prothorax much broader than long, narrowing from 
the base, constricted in front, densely punctate. Scutellum visible. Elytra moderately convex, a little 
wider than the prothorax, subparallel at the base, the humeri rounded ; coarsely seriate-punctate, the 
punctures closely placed, the interstices slightly raised and densely punctulate. Beneath closely, the sides 
of the metasternum more coarsely and sparsely, punctate. Legs short, moderately stout; anterior femora 
sharply, the others obsoletely, dentate. 
Length 33, breadth 2 millim. ( 9.) 
Hab. Mexico, Tapachula in Chiapas (Hoge). 
One specimen. Narrower and less convex than P. laticollis, the prothorax narrowed 
from the base, the elytra with two black spots on the suture towards the apex, the 
interstices densely punctulate, the legs not so stout, the anterior femora sharply dentate. 
5. Pseudomopsis distigma, sp. n. (Tab. XXIII. fig. 30.) 
Rhomboidal, shining, nigro-piceons: the prothorax clothed with intermixed, ochreous, blackish, and whitish 
scales; the elytra with a very large, sharply-defined, internally rounded space at the sides sparsely clothed 
with intermixed blackish and ochreous scales, the rest of their surface densely clothed with ochreous 
scales, the interstices each with a scattered series of semierect, larger scales; the head, under surface, 
and legs clothed with ochreous or whitish scales. Head densely punctate, the eyes well-separated ; 
rostrum sparsely, finely punctate, widened, rugulose, and subcarinate at the base. Prothorax conical, 
transverse, bisinuate at the base, densely punctate. Scutellum minute. Elytra convex, much wider than 
the prothorax, subtriangular, strongly sinuate at the base, the humeri rounded and not prominent ; 
punctate-striate, the interstices almost flat. Femora unarmed. 
Length 33, breadth 13 millim. 
Hab. Panama, Bugaba (Champion). 
One specimen. This species resembles Microxypterus binotatus in having a large, 
internally arcuate, dark space at the sides of the elytra. The strize appear to be quite 
narrow till the scales are removed. 
6. Pseudomopsis latisquamis, sp.n. (Tab. XXIV. figg. 1, 1a.) 
fon 
Subovate, shining, black, more or less variegated with rufo-piceous or ferruginous, the antenne ferruginous ; 
thickly clothed with intermixed ochreous, blackish, and white scales, the white scales condensed on the 
elytra into an oblique streak or some small spots on the anterior part of the disc and a transverse 
subapical fascia, the elytra also set with scattered, semierect, coarse, broad scales, these latter becoming 
numerous and closely clustered along the interstices 2 and 4, forming fascicles at the commencement of the
