CRYPTORRHYNCHUS. 651 
Species moderately large, oblong-ovate, convex, with the elytra, scutellum, and legs densely 
squamose, the eyes very large and contiguous, the rostrum arcuate, the prothorax short, 
deeply bisinuate at the base, the scutellum rather large, the elytra oblong, with the alternate 
interstices raised, the mesosternum arcuate-emarginate, the ventral segment 2 much longer 
than 3, the femora unidentate, the vestiture of the upper surface as in Metoposoma. 
(No. 31.) 
31. Cryptorrhynchus oculeus, sp.n. (Tab. XXXII. figg. 5, 5a.) 
Oblong-ovate, convex, shining, black, the antennew obscure ferruginous ; the pronotum sparsely clothed with 
blackish scales, with a white streak in the centre at the base, the rest of the vestiture closer and entirely 
whitish, with the exception of the following markings on the elytra, which are black—a transverse 
humeral patch, some irregular spots along the suture below this, a broad, common, post-median fascia, 
and a transverse apical spot. Head densely punctate, the eyes very large and contiguous; rostrum 
strongly curved, stout, rather longer than the prothorax, slightly widened, rugulosely punctate, and 
carinate at the base, and sparsely, minutely punctate thence to the tip, the antenne inserted at the 
middle, joint 2 of the funiculus a little shorter than 1, 5-7 moniliform, the club ovate. Prothorax 
transverse, arcuately narrowed from the middle, and feebly constricted in front; rather coarsely, 
confluently punctate, and sharply carinate. Scutellum moderately large, rounded. LElytra oblong, 
considerably wider than the prothorax; coarsely seriate-punctate, the interstices rugulose, 3, 5, 7, and 9 
more or less raised. Beneath sparsely punctate. Mesosternum prominent, arcuate-emarginate. Legs 
short and stout ; femora unidentate ; tibize carinate. 
Length 5-6}, breadth 24-3 millim. 
Hah. Panama, Bugaba, Volcan de Chiriqui (Champion). 
Five specimens. Very like the Guatemalan Staseas pullatus, but with larger, 
contiguous eyes, a rather large, rounded scutellum, raised alternate elytral interstices, 
simple tarsal claws, &c. The elytra are more densely squamose than the prothorax, 
and the black markings are sharply defined; the third interstice is much raised, the 
sutural region appearing depressed. The contiguous eyes, the broader prothorax, &c., 
separate C. oculeus from Metoposoma nigrofasciatum. 
Species small, oblong-ovate, squamose and setulose, with the eyes large, coarsely facetted, and 
narrowly separated, the antennal club elongate, the rostrum arcuate, widened towards the 
base, the prothorax bisinuate at the base, the scutellum small, the cavity rather large, the 
alternate elytral interstices narrowly costate, the mesosternum v-shaped, the metathoracic 
episterna broad, the ventral segments 2-4 rather long, equal in length, the legs short, the 
femora unidentate, the tibiz carinate, rounded externally. (Nos. 82, 33.) 
32. Cryptorrhynchus ruralis, sp. n. 
Oblong-ovate, robust, shining, nigro-piceous, the antenne and the tips of the tarsi obscure ferruginous ; 
thickly clothed (a broad patch on the dise of the prothorax excepted) with rather coarse brown scales, 
the elytra slightly mottled with black and with a few intermixed whitish scales ; the upper surface also 
set with semierect, short, scattered sete. Head rugulosely punctate, the eyes transverse, large, coarsely 
facetted, somewhat angular above, narrowly separated; rostrum arcuate, short, widened and rugosely 
punctate at the base, and sparsely, minutely punctate thence to the tip, the antenne inserted behind the 
middle, joints 3-7 of the funiculus transverse, together not longer than the elongate club. Prothorax
