CRYPTORRHYNCHUS. 657 
as the head and prothorax, a little widened towards the base and apex, rugosely punctate and 
subcarinate, with the apical half coarsely punctate, smoother in the 2, the antennz inserted at or 
behind the middle, joints 1 and 2 of the funiculus subequal in length, 4-7 moniliform, the club ovate. 
Prothorax nearly as long as broad, narrowed and constricted in front, the sides parallel behind; densely, 
finely punctate, the disc broadly depressed from a little before the base to the apex, swollen in the middle, 
and sharply carinate. Scutellum rather small. Elytra much wider than the prothorax, parallel in their 
basal half, and rapidly narrowing thence to the apex; alutaceous, seriate-punctate, the interstices 
(1 excepted) uneven or nodulose, 3-5 raised near the base and 2 and 38 also raised at the middle, 
1-3 seriato-granulate. Beneath alutaceous, closely, shallowly punctate. Mesosternum much raised, 
prominent in front. Legs rugosely punctate, the femora unidentate, the tarsi rather long and com- 
paratively slender. 
Length 94-113, breadth 43-54 millim. (¢ 2.) 
Hab. Nicaraeva (Sallé), Chontales (Belt, Janson, Richardson); Panama, Volcan de 
Chiriqui (Champ7on). 
Five specimens, the one from Chiriqui (fig. 14) being in better condition than 
the others, the black scales on the dorsal prominences of the elytra forming irregular 
markings in this insect. In general facies C. fulvicollis resembles Tylodinus planicollis, 
the latter having the prothorax similarly depressed on the disc. ‘The sculpture of the 
elytra is variable. 
42. Cryptorrhynchus bipupillatus, sp.n. (lab. XXXII. figg. 15, 15a, ¢.) 
Oblong-ovate, opaque, black, the antenne and the tips of the tarsi ferruginous; thickly clothed with inter- 
mixed reddish-brown and black scales, the latter condensed into two narrow, sinuous, interrupted lines 
on the dise of the prothorax and another on each side, and forming an irregular reticulation on the elytra, 
the elytra each with a whitish spot on the disc before the middle; the upper surface also somewhat 
closely set with short, coarse, black and fulvous seta ; the vestiture of the under surface paler, that of the 
femora and tibis dense, coarse, and setiform, fuscous and whitish intermixed, the whitish scales sometimes 
condensed into one or two rings. Head rugulosely punctate, the eyes widely separated ; rostrum very 
stout, widened towards the base and apex, rugosely punctate and carinate to about the middle, and 
closely, rather coarsely punctate thence to the apex, smoother in the 2. Prothorax a little broader than 
long, much narrowed and feebly constricted in front; densely punctate, the dise obliquely swollen on each 
side of the broad median depression behind, and also sharply carinate to near the base. Scutellum small. 
Elytra wider than the prothorax, parallel in their basal half ; seriate-punctate, the interstices uneven, 
very sparsely seriato-granulate, 2, 3, 5, and 7 interruptedly raised. Beneath densely punctate. Legs 
rugosely punctate, the femora unidentate. 
Length 64-94, breadth 3-43 millim. (d @.) 
Hab. Nicaraaua, Chontales (Belt) ; Panama, Volcan de Chiriqui (Champion). 
Seven specimens, the five from Chiriqui being in fresh condition and_ blacker 
than the others. Very near C. alboscutellatus, but with the scutellum small and not 
clothed with whitish scales, the elytra each with a white spot on the disc before the 
middle, their surface more uneven, the setosity closer and blacker. 
43. Cryptorrhynchus rugipes, sp.n. (Tab. XXXII. figy. 16, 16a, ¢.) 
Oblong-ovate, rather broad, dull, black, the antenne and the tips of the tarsi ferruginous ; thickly clothed 
with brown or reddish-brown scales, the elytra variegated with black or brownish-black (the dark scales 
chiefly clustered on or between the dorsal elevations) and each with a transverse white spot on the disc 
at about one-third from the apex, their surface also set with coarse, scattered, suberect sete ; the vestiture
