80. Cryptorrhynchus discicollis. 
Cryptorhynchus discicollis, Ros. in Schénh. Gen. Cure. iv. p. 103°; Boh. in Schénh. Gen. Cure. 
viii. 1, p. 328°. 
Hab. Mexico, Vera Cruz 2 (Chevrolat '). 
The type of this species cannot now be found in the Stockholm Museum, It is 
described as oblong-ovate in form, scarcely larger than the European rirrhinus 
acridulus, with the vestiture brown, the prothorax with a broad pallid space at the 
sides and six fascicles of erect scales on the disc; the elytra with a whitish patch at 
the middle near the suture and another near the apex, the alternate interstices raised ; 
the femora unidentate. C. discicollis is apparently a close ally of C. degressus. 
81. Cryptorrhynchus degressus, sp.n. (Tab. XXXIII. figg. 17, 17a, 2.) 
Very like C. cancellatus, but smaller; the vestiture brown or fulvous, the elytra often with indications of an 
ochreous or whitish interrupted median fascia, the prothorax with six fascicles of short, erect, black set 
(four across the middle and two at the apex), and two triangular black spots at the base, the sides marked 
with ochreous; the elytra less variegated with black, the black scales often clustered into an irregular, 
interrupted, transverse fascia below the base and another beyond the middle; anterior tibie@ sinuous, and 
the others almost straight, within ; anterior tarsi of the ¢ without longer projecting hairs. 
Var.? The prothorax with a space down the middle, which is abruptly narrowed anteriorly, and the elytra 
‘with a broad transverse space at the base, black. 
Length 3-43, breadth 13-2 millim. (d @.) 
Hab. Guatemata, Senahu, San Juan, Panima, and Purula in Vera Paz, Zapote 
(Champion); Panama, Bugaba, Volcan de Chiriqui (Champion). 
This is perhaps an extreme form of C. cancellatus, but as the male wants the long 
hairs on the anterior tarsi it seems best to treat it as distinct. C. degressus is a common 
insect in Chiriqui. The variety is represented by three specimens from Vera Paz, 
where the form selected as typical also occurred. Cryptorhynchus discicollis, Ros., 
from Mexico, is described as having similar fascicles of setee on the prothorax. 
82. Cryptorrhynchus bioculatus, sp.n. (Tab. XXXIII. fig. 18, 3.) 
Oblong-ovate, piceous, the antenne and the tips of the tarsi ferruginous; variegated above with a dense 
clothing of coarse brown, whitish or ochreous, and black scales, the whitish or ochreous scales condensed 
into an irregular cruciform patch on the prothorax and a large rounded or subtriangular spot at about 
the middle of the disc of each elytron, the black scales on the prothorax clustered into three subtriangular 
spots along each side of the ochreous median patch, and those on the elytra condensed into irregular 
markings, tle suture sometimes broadly fulvous posteriorly; the upper surface also somewhat thickly 
set with coarse, erect, blackish and pallid sete; the vestiture of the under surface and legs cinereous or 
ochreous, the legs coarsely setose and fusco-annulate. Head ruguloscly punctate, the eyes distant ; 
rostrum not longer than the prothorax, feebly curved, slightly widened towards the base, rugulosely 
punctate, a little smoother in the 9, the antenne inserted behind the middle, joint 2 of the funiculus 
nearly as long as 1, the club ovate. Prothorax transverse, constricted and much narrowed in front; 
closely, coarsely punctate. Scutellum rounded. Elytra very little wider than the prothorax, narrowing 
from about the basal third; coarsely seriate-punctate, the interstices 3 and 5 raised, the others feebly
