CRYPTORRHYNCHUS. 655 
Species moderately large or small, oblong-ovate or subovate, squamose and often setose, with the 
antennal club ovate, the eyes distant, the rostrum curved, the prothorax bisinuate at the 
base, the scutellum filling the cavity, the elytra much wider than the prothorax, often 
granulate and with the alternate interstices raised, the mesosternum prominent, arcuate- 
emarginate, the metathoracic episterna moderately broad (except in C. fulvicollis), the 
ventral segment 2 longer than 8, the legs rugosely punctate and more or less setose, the 
femora unidentate, the anterior tarsi sometimes ciliate in the males (C. alboscutellatus, 
C. scutatus, and C. hirtimanus). The less deeply emarginate mesosternum separates the 
species with hairy tarsi from the genus Cophes. (Nos. 88-56.) 
Anterior tarsi with projecting hairs in the ¢. (Nos. 38-40.) 
Anterior tarsi without projecting hairs in the g. (Nos. 41-56.) 
38. Cryptorrhynchus alboscutellatus, sp.n. (Tab. XXXII. figg. 11, 11a, 3.) 
Oblong-ovate, opaque, black, the antenne and the tips of the tarsi ferruginous ; thickly clothed with reddish- 
brown scales, the prothorax and elytra variegated with black, the scutellum and a transverse or sub- 
quadrate spot on the disc of each elytron towards the apex white or ochreous, the elytra also set with 
short, scattered, coarse sete; the vestiture of the under surface pale, that of the femora and tibie dense, 
coarse, and setiform, fuscous and whitish intermixed, the whitish scales on the tibise: condensed into an 
annulus at the base and apex. Head densely punctate, the eyes widely separated; rostrum rugosely 
punctate and subcarinate to about the middle, and thickly punctate thence to the apex, smoother in the 9. 
Prothorax transverse, much narrowed in front; densely, finely punctate, the disc broadly depressed down 
the middle from the base to the apex (the depression limited on each side posteriorly by an oblique 
swelling), and also sharply arcuato-carinate from the apex to near the base. Scutellum large, rounded. 
Elytra considerably wider than the prothorax, parallel in their basal half, flattened along the suture; 
alutaceous, seriate-punctate, the interstices seriato-granulate, 2,3, and 5 more or less raised, the outer ones 
convex. Beneath alutaceous, densely punctate. Legs rugosely punctate, the femora unidentate ; anterior 
tarsi of the ¢ with a few fine projecting hairs. 
Length 7-83, breadth 34-4 millim. (¢ 2.) 
Hab. Mexico (e# coll. Flohr); Guatemata, El Reposo, Las Mercedes, Mirandilla 
(Champion), Escuintla (Conradt). 
Five specimens. In this insect the depression on the disc of the prothorax is 
continued, as it were, down the elytra, the sutural region of the latter being flat and 
the second and third interstices raised. The scutellum is large and clothed with white 
scales. The blackish scales'on the upper surface are clustered into four small patches 
on the prothorax (two at the apex and two at the base) and various irregular markings 
on the elytra. 
39. Cryptorrhynchus scutatus, sp.n. (Tab. XXXII. figg. 12, 12a, 3.) 
Oblong-ovate, opaque, black, the antenne ferruginous; somewhat sparsely clothed with intermixed reddish- 
brown and black scales, the black scales on the prothorax mostly clustered along the sides and apex and 
on the median elevation, and those on the elytra condensed into various irregular patches, the vestiture 
of the scutellum ochreous, and that of the under surface sparse and pale ; the upper surface also set with 
short, coarse, scattered sete ; the femora and tibie coarsely, densely setose, subannulate. Head densely 
punctate, the eyes widely separated ; rostrum stout, rugosely punctate to the apex in the ¢, the apical 
half more sparsely punctate in the 9, the antennew inserted at the middle. Prothorax transverse, 
arcuately dilated at the sides before the middle and abruptly narrowed in front ; the sides and base
