662 RHYNCHOPHORA. 
near the base in the 9, the antenne inserted behind the middle, joint 2 of the funiculus slightly shorter 
than 1, the club ovate. Prothorax transverse, narrowed and feebly constricted in front ; densely, finely 
punctate, and also carinate. Elytra rather short, wider than the prothorax, subparallel in their basal 
half; seriate-punctate, the interstices alutaceous, sparsely granulate, 2-9 more or less raised, 2, 3, and 5 
rather prominent. Beneath very densely punctate. Mesosternum prominent, feebly emarginate. Legs 
rugose ; femora sharply unidentate. 
Length 42-5, breadth 27,-22 millim. (¢ 2.) 
Hab. Panama, Bugaba (Champion). 
One pair. This insect is very like C. ignodilis, but it has the prothorax less constricted 
in front, and the fascicles of black sete are wanting, and the elytra have a conspicuous 
oblique white streak on the disc before the middle. ‘The erect setiform scales on the 
prothorax are very short, while those on the elytra ‘are as long as in C. égnobilis. 
53. Cryptorrhynchus commixtus, sp.n. (Tab. XXXII. figg. 22, 22a, ¢ .) 
Very like C. fraterculus, but a little more elongate; the rostrum stouter and very rugose ; the prothorax more 
dilated at the sides, the short black setiform scales clustered into a curved streak on each side of the disc, 
a marginal stripe, and two fascicles at the apex; the elytra more closely variegated with black, with a 
basally dilated, curved, ochreous streak extending from the humeri inwards, the other scales brown, the 
erect sets very short and stout; the femora feebly unidentate. 
Length 53, breadth 23 millim. (d.) 
Hab. Honpvras (Sallé). 
One specimen, evidently distinct from C. fraterculus, the difference in the armature 
of the femora alone being sufficient to distinguish it. 
54, Cryptorrhynchus tenebrosus, sp. n. (Tab. XXXII. fig. 23, 2.) 
Oblong-ovate, opaque, black, the antennz and the tips of the tarsi more or less ferruginous ; somewhat thickly 
clothed with small blackish scales (the vestiture becoming sparser and finer towards the suture), the 
scutellum, a small patch in front of it, and an oblique streak on the disc of each elytron before the middle 
(the two streaks sometimes connected at the suture), whitish or cinereous, the elytra also set with short, 
semierect sete; the vestiture of the under surface cinereous, that of the legs blackish and cinereous 
intermixed, the femora and tibie subannulate. Head densely punctate, the eyes widely separated ; 
rostrum stout, feebly curved, about as long as the prothorax, slightly widened towards the base and apex, 
rugosely punctate, the apical half shining and rather sparsely punctate in the 2, the antenna inserted 
at (3) or a little behind ( 2) the middle, joints 1 and 2 of the funiculus subequal in length, the club 
ovate. Prothorax nearly as long as broad, narrowed and feebly constricted in front, somewhat flattened 
on the disc; densely, finely punctate, and arcuately carinate to near the base. Scutellum rounded. 
Elytra much wider than the prothorax, subparallel in their basal half; seriate-punctate, the interstices 
alutaceous, sparsely seriato-granulate, 3 interruptediy raised, becoming prominent at the base, 5 and 7 
also raised anteriorly. Beneath densely punctate. Mesosternum broad, arcuate-emarginate. Legs 
moderately long, rugose ; femora strongly unidentate; tibize sinuous within. 
Length 42-54, breadth 2-23 millim. (¢ 2.) 
Hab. Nicaracua, Chontales (Belt) ; Panama, Bugaba (Champion). 
Eight specimens, one only of which is from Nicaragua. ‘The vestiture of the 
upper surface in this insect is almost entirely blackish, with the exception of the 
oblique whitish streak on the disc of each elytron and the other markings noticed
