CRYPTORRHYNCHUS. 647 
this, also black; the vestiture of the legs close, reddish-brown, the tibiwe fusco-annulate; the flanks 
of the prothorax and elytra almost bare. Head closely punctate, the eyes widely separated; rostrum 
moderately stout, curved, rugosely punctate and tricarinate in its basal half, and sparsely, finely punctate 
thence to the tip, smoother in the 2. Prothorax transverse, rounded at the sides anteriorly, constricted 
and narrowed in front; closely, rather finely punctate. Scutellum small. Elytra a little wider than the 
prothorax, narrowing from before the middle, the humeri obtuse; seriate-punctate, the interstices some- 
what convex and finely seriato-granulate. Beneath dull, somewhat closely punctate. Mesosternum 
horseshoe-shaped. Legs moderately stout; femora unidentate; anterior tarsi of the g¢ with a few 
projecting hairs. 
Length 53-63, breadth 23-3 millim. (¢ ?.) 
Hab. Panama, Bugaba (Champion). 
Four specimens. ‘This is the Panama representative of the Mexican C. scopulatus, 
differing from that species in its less elongate shape, the duller surface, the shorter 
prothorax, the more extended dark markings of the elytra (there being no trace of the 
apical patch in C. scopulatus), and the more sparsely ciliate anterior tarsi of the male. 
25. Cryptorrhynchus alutaceus, sp.n. (Tab. XXXI. figg. 30, 30a, 3.) 
Oblong-ovate, robust, opaque, alutaceous, black, the antennz ferruginous ; very sparsely clothed with fulvous 
or reddish scales, which are clustered into small scattered fascicles on the elytra and short irregular 
streaks on the prothorax, the upper surface also set with short, coarse, decumbent sete, the head some- 
times variegated with whitish, the legs with intermixed reddish, ochreous, and fuscous scales, the femora 
subannulate. Head coarsely, rugosely punctate, the eyes widely separated ; rostrum feebly curved, very 
stout, dilated and flattened towards the apex, about as long as the prothorax, alutaceous, coarsely seriate- 
punctate, the punctures becoming finer and shallower on the apical half in the ¢ and almost obsolete in 
the 2, the antennz inserted at ( ¢) or a little behind (9 ) the middle, joint 2 of the funiculus elongate, 
the club short-ovate, with transverse sutures. Prothorax transverse, constricted and much narrowed 
in front, the anterior portion tubulate; rugosely punctate and subgranulate, and with a short carina 
at the middle of the disc. Scutellum rounded, level with the elytra. Elytra slightly wider than the 
prothorax, narrowing from a little below the base, the humeri obtuse; with rows of rather coarse rounded 
punctures, the interstices somewhat convex, and with scattered shining granules. Beneath coarsely, 
sparsely punctate. Mesosternum broad and prominent, arcuate-emarginate. Legs moderately stout, 
- rather long, the femora sublinear, unidentate. 
Length 6-83, breadth 27-4 millim. (¢ 2.) 
Hab. Panama, Bugaba, Volcan de Chiriqui (Champion). 
Six specimens. In this insect the entire surface (the small granules on the elytra 
excepted) is opaque and alutaceous. The vestiture is very sparse and rust-red in 
colour, becoming fasciculate on the elytra. C. alutaceus is perhaps nearest related to 
C. plagiaticollis. 
Species small, densely squamose, with the eyes large and subcontiguous, the antennal club 
oblong, the prothorax short, the elytra triangular and coarsely fasciculate, the mesosternal 
cavity long, the ventral segments 2—4 subequal in length, the anterior femora bi-, and the 
others unidentate. (No. 26.) 
26. Cryptorrhynchus formosus, sp.n. (Tab. XXXI. figg. 31, 31a, 3.) 
Somewhat rhomboidal, black, the elytra mottled with rufo-piceous towards the tip, the rostrum similarly 
coloured, the antenne ferruginous; variegated above with a dense clothing of intermixed whitish,
