634 RHYNCHOPHORA. 
and whitish scales, those on the prothorax large and reddish-brown in colour, the elytra slightly mottled 
with black, the tibiz also set with very short setiform scales ; the vestiture of the under surface sparser 
and very coarse. Head coarsely, closely punctate, the eyes widely separated; rostrum stout, feebly 
curved, very little longer than the prothorax, rugulosely punctate and subcarinate at the base, becoming 
rather sparsely punctate towards the tip, the antenne inserted beyond the middle, joint 2 of the funiculus 
slightly longer than 1, the club stout, ovate. Prothorax a little broader than long, gradually narrowing 
from near the base, the latter strongly bisinuate; very coarsely, confluently punctate and also finely 
carinate. Scutellum oblong. Elytra convex, much wider than the prothorax, elongate-subtriangular, the 
humeri rounded ; very coarsely seriate-punctate, the interstices (2 and 4 excepted) raised or subcarinate, 
the suture also raised throughout. Beneath coarsely punctate. Mesosternum horseshoe-shaped. Legs 
stout, the femora unidentate. 
Length 12, breadth 53 millim. (3?) 
Hab. Mexico, Cerro de Plumas (Hége). 
One specimen. This insect approaches the Brazilian Cryptorhynchus gauspatus, 
Boh.*, but the latter has all the elytral interstices costate, the eyes separated by less 
than the width of the rostrum, the prothorax more strongly carinate, &c. The scales 
on the prothorax are large, and uniform in size and colour. 
2. Cryptorrhynchus cordubensis, sp.n. (Tab. XXXI. figg. 9, 9a, .) 
Oblong-ovate, robust, black, the antenne obscure ferruginous ; somewhat thickly clothed with coarse, 
intermixed, ochreous and whitish scales, those on the prothorax mostly large, with narrow ones 
intermixed, the elytra slightly mottled with black. Head coarsely, rugosely punctate, the eyes widely 
separated ; rostrum rather short, stout, curved, rngosely punctate at the base, the punctures becoming 
more scattered towards the tip, the antenne inserted a little beyond the middle, joints 1 and 2 of the 
funiculus subequal in length, the club ovate. Prothorax gradually narrowing from a little before the 
base, the base itself strongly bisinuate; coarsely, confluently punctate, without definite median carina. 
Scutellum oblong. Elytra convex, elongate-subtriangular, the humeri rounded ; very coarsely seriate- 
punctate, the punctures oblong-subquadrate in shape, the interstices 3 and 5 carinate and slightly sinuate, 
the suture also raised throughout. eneath coarsely, closely punctate. Legs stout, the femora 
unidentate. 
Length 84, breadth 4 millim. (<.) 
Hab. Mexico, Cordova (Hége). 
A single example. Smaller than C. mistus, the rostrum shorter, the prothorax not 
carinate, with broad and narrow scales intermixed, the third elytral interstice more 
sharply raised, the vestiture paler and mottled on both the prothorax and the elytra. 
3. Cryptorrhynchus latisquamis, sp. n. (Tab. XXXI. fige. 10, 10a, 2.) 
Oblong-ovate, convex, shining, black, the antenne obscure ferruginous ; thickly clothed with coarse, intermixed, 
brownish and white scales, the elytra also slightly mottled with brownish-black, the scales on the 
prothorax large, the white ones on the latter clustered into six spots (three at the base and three at the 
apex) and those on the elytra condensed into a common, irregular, interrupted, X-shaped mark on the 
disc, which extends inwards at the base, the elytra also set with scattered, short, decumbent sete. Head 
rugosely punctate, the eyes separated by the width of the rostrum ; rostrum moderately stout, curved, a 
little longer than the prothorax, rugosely punctured at the sides towards the base, and for the rest almost 
smooth, the antenne inserted at the middle, joints 1 and 2 of the funiculus subequal in length, the club 
* C. gauspatus belongs to Jekel’s section Polypleurus, a name preoccupied by Eschscholtz in Tenebrionide.
