CRYPTORRHYNCHUS. 677 
convex. Beneath alutaceous, sparsely, rather finely punctate. Mesosternum prominent, arcuate- 
emarginate. Legs short; femora unidentate, the tooth on the posterior pair long and sharp, that on 
the anterior pair often obsolete; tibie subangulate at the base externally. 
Length 32-44, breadth 13-2 millim. (¢ 2.) 
Hab. Panama, Bugaba, Volcan de Chiriqui, Tolé (Champion). 
Sixteen specimens. Recognizable by the large, sharply-defined, ochreous or whitish 
spot on the disc of each elytron, and the similarly-coloured cruciform patch on the 
prothorax. The elytra sometimes have a broad space down the suture fulvous, this, 
with the discoidal spots, forming a second cruciform patch. The sculpture is partly 
hidden by the dense vestiture. 
83. Cryptorrhynchus stigmatophorus, sp. n. (Tab. XXXII. fig. 19, ¢ .) 
Oblong-ovate, rather narrow, piceous, the antenne and the tips of the tarsi ferruginous ; densely clothed with 
moderately coarse scales, with numerous erect coarse sete intermixed; the prothorax with an interrupted 
cruciform mark on the disc, the scutellum, and the elytra with a common, elongate patch—extending from 
about the basal fourth to the apex, transversely or obliquely dilated anteriorly, and often constricted or 
divided at the middle,—ochreous or whitish, the rest of the upper surface blackish or brown ; the vestiture 
of the flanks of the prothorax, under surface, and legs paler, the legs setose and fusco-annulate. Head 
rugulosely punctate, the eyes distant; rostrum rather sparsely punctate beyond the middle in both sexes. 
Prothorax and elytra as in C. biocwlatus. Femora unidentate. 
Length 3-41, breadth 17-1? millim. (¢ 9.) 
Hab. British Honpuras, Rio Hondo (Blancaneaux) ; GuateMALA, Chacoj in Vera 
Paz, Zapote (Champion); Panama, Bugaba, Caldera, Volcan de Chiriqui, Tolé 
(Champion). 
Many specimens, mostly rather worn. A close ally of C. bioculatus, and occurring at 
the same localities in Chiriqui, but easily distinguishable when examples in good con- 
dition are compared, the elytral markings being very different. ‘The common, elongate, 
bidilatate, pallid apica] patch varies in extent, and is sometimes divided across the 
middle, the outer anterior portions representing the discoidal spots of C. dioculatus. 
84. Cryptorrhynchus distigma, sp. n. 
Oblong-ovate, nigro-piceous, the antennz and the tips of the tarsi ferruginous ; variegated above with a some- 
what dense clothing of fulvous and black scales, the scutellum and a small transverse patch at about the 
middle of the dise of each elytron white or yellowish-white, the prothorax and elytra also set with very 
short, decumbent, setiform scales ; the legs and under surface with intermixed brown and whitish scales, 
the legs fusco-annulate. Head rugulosely punctate, the eyes distant; rostrum about as long as the 
prothorax, rugulosely punctate at the base, and thickly punctate thence to the tip, the antenne inserted 
behind the middle. Prothorax transverse, rounded at the sides, abruptly narrowed and constricted in 
front; densely, rather finely punctate. Elytra slightly wider than the prothorax ; seriate-punctate, the 
interstices 3 and 5 more or less raised, the others feebly convex. Beneath alutaceous, finely punctate. 
Mesosternum prominent, arcuate-emarginate. Femora unidentate, the anterior pair compressed at the 
base. Tibie subangulate at the base externally. 
Length 3,1,-32, breadth 13-13 millim. (@.) 
Hab. Mexico, Jalapa, Cerro de Plumas (//oge) ; Guatemata, Cerro Zunil (Champion).
