CRYPTORRHYNCHUS. 665 
granulate, 3, 5, 7, and 9 slightly raised. Beneath densely, the ventral segments 2-4 sparsely, punctate. 
Legs short and stout ; femora unidentate. 
Length 5, breadth 24 millim. (<¢.) 
Hab. Panama, Bugaba (Champion). 
One specimen. Smaller and narrower than C. biguttatus, the vestiture coarser, the 
elytra each with a large, triangular, lateral black patch and a small black spot near 
the apex, the prothorax slightly narrowed behind, the ventral segments coarsely 
squamose, 2-4 subequal in length, the tibie nigro-annulate at the base, the antennal 
club ovate, the episterna narrower. 
Species rather small, oblong or elongate, squamose, with the eyes large and coarsely facetted, 
the rostrum arcuate, the antennal club oblong, the prothorax transverse, bisinuate at the 
base, the scutellum prominent, the elytra rather elongate, fasciculate, with the alternate 
interstices narrowly (and sometimes sinuously) costate, the mesosternum horseshoe-shaped, 
the ventral segments 2-4 subequal in length, the femora strongly unidentate, the anterior 
pair sometimes with a small additional tooth. (Nos. 59-61.) 
59. Cryptorrhynchus tortuosus, sp.n. (Tab. XXXII. figg. 28, 28a, ¢.) 
Oblong, shining, black, the antenne and the tips of the tarsi ferruginous; somewhat thickly clothed with 
small, intermixed brown, fulvous, and white scales, the elytra also variegated with black; the upper 
surface set with erect, rather coarse, fulvous and blackish, setiform scales, which are clustered into 
fascicles on the elevations—five in a transverse series across the disc of the prothorax (the one on each 
side of the middle composed of very long setie) and two at its apex, and three along the third elytral 
interstice; the femora subannulate with white, the vestiture of the abdomen sparse. Head closely 
punctate, transversely depressed at some distance above the eyes, the latter rather narrowly separated ; 
rostrum curved, very stout, about as long as the head and prothorax, widened, rugosely punctate, and 
tricarinate at the base, and sparsely punctate thence to the tip, a little smoother in the 9, the antenne 
inserted behind the middle, joints 1 and 2 of the funiculus subequal in length, the club oblong-ovate, 
acuminate. Prothorax strongly transverse, abruptly narrowed in front; densely punctate, the disc 
swollen on each side of the short, arcuate, median carina. Scutellum convex, prominent, surrounded by 
a deep cavity. Elytra considerably wider than the prothorax, gradually narrowing from a little below 
the base, the humeri somewhat swollen ; coarsely seriate-punctate, the rows 3-5 strongly sinuate, the 
interstices punctulate, 3, 5, 7, and 9 sharply costate, the ridge on 3 interrupted below the base and that 
on 5 abruptly sinuate before the middle. Beneath coarsely, rather sparsely punctate. Mesosternum 
prominent, horseshoe-shaped. Legs moderately stout; femora sharply unidentate, the anterior pair 
stout and sinuous; tibie more or less curved externally. 
Length 4;4-52; breadth 2-23 millim. (¢ 2.) 
Hab. Panama, Bugaba, Volcan de Chiriqui (Champion). 
Seven specimens. ‘The abruptly sinuate ridge on the fifth elytral interstice separates 
this species from all its allies. ‘There is a form from Cayenne somewhat like it in the 
British Museum labelled with the MS. name Celosternus leprieurt, Buq. 
60. Cryptorrhynchus singularis, sp.n. (Tab. XXXII. figg. 29, 29a, 2.) 
Moderately elongate, shining, black, the antenne and the apices of the tarsi obscure ferruginous; densely 
clothed with intermixed pale brown, whitish, and fulvous scales, the scales on the prothorax coarse and
