664 RHYNCHOPHORA. 
Cryptorhynchus indecorus, Ros., from Brazil, seems to be an allied form; it is 
described as having the anterior femora almost unarmed, the base of the prothorax 
subtruncate, &c. 
Species rather small, oblong-ovate, thickly squamose and setulose, with the rostrum strongly 
arcuate, the antennal club oblong-ovate or ovate, the eyes large and not very widely 
separated, the prothorax deeply bisinuate at the base and with the truncated hind angles 
received into the excavate base of the elytra, the scutellum rounded, the elytra oblong, 
with a large black lateral patch, the mesosternum arcuate-emarginate, the metathoracic 
episterna moderately broad, uniseriate-punctate, the ventral segment 2 as Jong as or 
longer than 38, the femora unidentate. (Nos. 57, 58.) 
57. Cryptorrhynchus biguttatus, sp.n. (Tab. XXXII. figg. 26, 26a, 2.) 
Oblong-ovate, black, the antennx and the tips of the tarsi ferruginous; the prothorax sparsely, and the rest 
of the surface densely, clothed with small fulvo-cinereous scales, with intermixed longer and coarser 
scales, both above and beneath, those on the elytra semierect and setiform, and arranged in a scattered, 
irregular series along each interstice, the elytra each with a very large, inwardly rounded, black, lateral 
patch placed at about the middle, which is broadly bordered with cinereous scales. Head rugosely 
punctate, the eyes large and rather narrowly separated ; rostrum shining, strongly curved, about as long 
as the head and prothorax, rugosely punctate and carinate at the base, almost smooth in its apical half, 
the antenn inserted at the middle, joints 1 and 2 of the funiculus subequal in length, the club oblong- 
ovate. Prothorax transverse, rounded at the sides anteriorly, constricted and narrowed in front, deeply 
sinuate at the base; densely, confluently punctate, and also carinate. Scutellum rather large. LHlytra 
considerably wider than the prothorax, gradually narrowing from a little below the base; seriate- 
punctate, the interstices rugulose and obsoletely granulate, 3, 5, 7, and 9 slightly raised. Beneath 
closely punctate ; ventral segment 2 much longer than 3. Mesosternum prominent, arcuate-emarginate. 
Metathoracic episterna broad. Legs moderately stout, rather short; femora feebly clavate and sharply 
unidentate. 
Length 61-64, breadth 3 millim. (9.) 
Hab. Mexico, Amatan in Chiapas (ex coll. Flohr); Nicaragua, Chontales (Belt). 
Two specimens, agreeing perfectly inter se. This is one of several Central- 
American Cryptorrhynchids with a large black lateral patch on each elytron, the 
following being the only species nearly allied to it. 
58. Cryptorrhynchus bimaculatus, sp.n. (Tab. XXXII. figg. 27, 27a, ¢.) 
Oblong-ovate, black, the antenne and the tips of the tarsi ferruginous ; thickly clothed (except upon the head 
and the disc of the prothorax) with rather coarse brownish scales, the elytra with paler scales intermixed 
and each with a very large subtriangular lateral patch (nearly reaching the shoulder), and a small spot 
on the outer margin near the apex, black, the interstices each with a scattered series of coarse, semierect 
scales, the tibie nigro-annulate at the base; the abdomen sparsely clothed with coarse pallid scales. 
Head coarsely, rugosely punctate, the eyes moderately distant ; rostrum shining, stout, strongly curved, 
not longer than the prothorax, rugosely punctate at the base and finely punctate thence to the tip, the 
antenne inserted at about the middle, joint 2 of the funiculus shorter than 1, the club ovate. Prothorax 
transverse, rounded at the sides, narrowed in front, deeply sinuate at the base; rather coarsely, 
confiuently punctate, and obsoletely carinate. Scutellum rounded. Elytra shining, a little wider than 
the prothorax, subparallel in their basal half; seriate-punctate, the interstices punctulate and feebly
