696 RHYNCHOPHORA. 
Species small, subovate, densely squamose and setose, with the rostrum arcuate, widened at the 
base, the eyes distant, the antennal club elongate, the prothorax bisinuate at the base, the 
scutellum small, the elytra much wider than the prothorax, with the alternate interstices 
costate, the mesosternum deeply, angularly emarginate, the metathoracic episterna mode- 
rately broad, the ventral segments 2—4 subequal in length, the legs short and stout, the 
femora unidentate. (No. 122.) 
122. Cryptorrhynchus sexnotatus, sp.n. (Tab. XXXIV. figg. 15, 15 a.) 
Subovate, black, the apex of the rostrum, the antenne, and the tips of the tarsi ferruginous; thickly clothed 
with rather coarse pale brown scales, the prothorax with two short, interrupted, bare, blackish vitte on 
the disc, the flanks ochreous, the elytra each with three velvety-black patches (the first subtriangular, 
on the disc before the middle, the second oblong, subquadrate, beyond the middle, and close to the suture, 
the third small, towards the apex) ; the upper surface also set with rather coarse, erect seta, the legs 
setulose ; the vestiture of the under surface sparse and somewhat piliform. Head densely punctate, 
transversely depressed above the widely separated, coarsely facetted eyes; rostrum curved, not longer 
than the prothorax, widened, squamose, and rugulosely punctate at the base, the apical half bare and 
rather sparsely punctate, the antenne inserted at about the middle, joint 2 of the funiculus shorter than 1, 
the club elongate-ovate, compact. Prothorax broad, transverse, somewhat dilated at the sides, abruptly 
narrowed and strongly constricted in front; densely punctate, and carinate from the base to the apex. 
Scutellum small. Elytra rather short, considerably wider than the prothorax, narrowing from near the 
base, the humeri obliquely truncated and somewhat prominent ; seriate-punctate, the interstices 3, d, 7, 
and 9 costate. Beneath alutaceous, rather sparsely punctate. Mesosternum v-shaped. Legs short and 
stout; femora unidentate ; tibie rounded at the base externally, the anterior pair sinuate within. 
Length 4-4,54,, breadth 2-254, millim. (9?) 
Hab. Panama, David in Chiriqui (Champion). 
Two specimens. This insect, which is of about the same size and shape as Hubulus 
lineatulus (but with less convex elytra), is recognizable by the sharply-defined velvety- 
black patches on the elytra, the abruptly constricted, interruptedly bivittate, carinate 
prothorax, the short, stout legs, and the setose upper surface. It could perhaps be 
included under Section A of Ludulus. 
Species small, ovate, densely squamose and finely setose, with the eyes very large and narrowly 
separated, the rostrum feebly curved, the antennal club ovate, the prothorax deeply bisinuate 
at the base, the scutellum rounded and filling the cavity, the elytra much wider than the 
prothorax, with the alternate interstices slightly raised, the mesosternum U-shaped, the 
metathoracic episterna broad, the ventral segments 2—4 equal in length, the femora uni- 
dentate, the tibiz subangulate at the base externally. (No. 123.) 
123. Cryptorrhynchus quadrisignatus, sp. n. (Tab. XXXIV. figg. 16, 
16a, 3.) 
Ovate, nigro-piceous, the apical half of the rostrum, the antenne, and the tarsi in part, ferruginous: thickly 
clothed with blackish or dark brown scales, the scutellum whitish, the base of the rostrum, a line round 
the eyes, and the under surface brownish-cinereous, the legs with intermixed cinereous scales ; the upper 
surface ‘also sparsely set with erect, brownish and black sete, the elytra each with two oblique or oblong 
clusters of coarser, raised, black scales on the disc (one before, the other slightly beyond, the middle), 
the posterior two sometimes united into a common curved fascia. Head densely punctate, the eyes very
