CRYPTORRHYNCHUS. 705 
Species small, subovate, squamose and setulose, with the eyes very large, the rostrum feebly 
curved, the antennal club oblong-ovate, the elytra with a large, common, rounded, sharply- 
defined, black patch at the base, the mesosternum arcuate-emarginate and very prominent, 
the ventral segments 2—4 subequal in length, the femora unidentate. (Nos. 134, 135.) 
134. Cryptorrhynchus disciger, sp.n. (Tab. XXXIV. fig. 26, ¢.) 
Subovate, black, shining, the antennw, the tip of the rostrum, and the apices of the tarsi ferruginous ; densely 
clothed with small brown scales, the legs and under surface with intermixed cinereous scales, the elytra 
with a large, rounded, common, anteriorly narrowed, velvety-black patch immediately below the base, the 
upper surface also somewhat thickly set with short, semierect sete. Head densely punctate, the eyes 
large, finely facetted, and rather narrowly separated ; rostrum curved, about as long as the prothorax, 
widened towards the base, rugosely punctate to the tip, the antenne inserted at about the middle, joint 2 
of the funiculus a little shorter than 1, 3-7 transverse, closely articulated, and widening outwards, the 
club oblong-ovate. Prothorax transverse, rounded at the sides anteriorly, much narrowed and feebly 
constricted in front; densely, finely punctate. Scutellum minute, smooth. Elytra much wider than 
the prothorax, narrowing almost from the base; scriate-punctate, the interstices punctulate, feebly 
convex. Beneath dull, densely punctate. Mesosternum raised and very prominent, feebly emarginate. 
Legs rather slender, the femora unidentate. 
Length 33, breadth 14 millim. (<¢.) 
Hab. Panama, Volcan de Chiriqui (Champion). 
One specimen. The large, common, subcordate, velvety-black patch on the elytra 
immediately below the base separates this species from all its allies, the following 
excepted. 
135. Cryptorrhynchus scutiger, sp.n. (Tab. XXXIV. fig. 27, 2.) 
Extremely like C. disciger, but with the black patch on the elytra heart-shaped and reaching the base, the 
prothorax with two setigerous prominences at the apex; the setiform scales shorter; the rostrum less 
rugose. 
Length 4, breadth 2 millim. (2?) 
Hab. Mexico, Jalapa (/ége). 
One immature example, which I do not hesitate to separate from the southern 
C. disciger. ‘The black patch on the elytra in the Mexican insect is broadest in front. 
(instead of behind) and reaches the base. In C. disciger, too, there is no trace of 
setigerous prominences at the apex of the prothorax. 
Species small, oblong-ovate, squamose and strongly setose, with the rostrum arcuate, the eyes 
large and partly exposed, the antennal club oblong-ovate, the elytra a little wider than the 
prothorax and each with a large, black, eye-like spot on the disc, the mesonotum horseshoe- 
shaped, the ventral segments 2-4 subequal in length, the legs short, the femora unidentate, 
the metathoracic episterna narrow. (No. 136.) 
136. Cryptorrhynchus melanophthalmus, sp.n. (Tab. XXXIV. figg. 28, 
28 a.) | 
Oblong-ovate, opaque, black, the antenne and the tips of the tarsi (and in one specimen the rostrum also) 
ferruginous ; densely clothed with dark brown scales, with a few greyish scales intermixed (especially on
