654 RHYNCHOPHORA. 
into a faint, interrupted median line on the prothorax, and condensed on the elytra into an oblique 
streak below the base and a common, interrupted, transverse, post-median fascia, the elytra also 
variegated with black on the disc, the femora and tibie annulated with fuscous or black; the upper 
surface set with very short, decumbent, light and dark sete. Head rugosely punctate, the eyes distant ; 
rostrum stout, feebly curved, about as long as the prothorax, closely, rather coarsely punctate, rugose at 
the base, and finely carinate, that of the Q sparsely, finely punctate in its outer two-thirds, the antenne 
inserted at (¢) or behind (2) the middle, joints 3-7 of the funiculus transverse and closely articulated, 
2 shorter tha 1, the club oblong-ovate, with oblique sutures. Prothorax transverse, narrowed and 
feebly constricted in front; coarsely, closely punctate and subgranulate, except along a narrow space 
down the middle. Scutellum rounded. Elytra oblong, slightly wider than the prothorax, flattened along 
the suture, the humeri obtuse; seriate-punctate, the interstices rugulose and somewhat closely granulate, 
3, 5,7, and 9 raised. Beneath coarsely punctate. Mesosternum prominent, arcuate-emarginate. Legs 
rather stout, moderately long ; femora feebly clavate and strongly unidentate. 
Length 64-8, breadth 23-33 millim. (3 9 .) 
Hab. Costa Rica, San José (Biolley) ; Panama, Bugaba (Champion). 
Two specimens from each locality. Very like Celosternus maculipes, Boh., from 
Brazil, but with the prothorax less abruptly narrowed anteriorly, and the whitish 
elytral markings more extended outwards, the elytra themselves more closely granulate. 
Smaller than C. albitarsus, the legs much shorter, the antennal club less elongate, the 
markings of the elytra different. 
Species rather small, subovate, densely squamose and setulose, with the eyes distant aud rather 
prominent, the rostrum curved, the antennal club ovate, the prothorax subtruncate at the 
base and binodose on the disc, the elytra broad, with prominent, obliquely truncated humeri 
and oblong setigerous prominences on the third interstice, the mesosternum raised and 
feebly emarginate, the ventral segment 2 much longer than 3, the legs slender, the femora 
unidentate. (No. 87.) 
37. Cryptorrhynchus bivittatus, sp.n. (Tab. XXXII. figg. 10, 10a, ¢.) 
Subovate, dull, black, the antenne and tarsi obscure ferruginous ; thickly clothed with brownish scales, those 
on the flanks of the prothorax and on the scutellum paler, the prothorax with two broad, sinuous, 
black vitte on the disc, which are continued on to the vertex, the elytra mottled with black and with a 
faint, transverse, common, ochreous fascia beyond the middle; the upper surface also set with short, 
scattered, semierect sete, which become fasciculate on the dorsal elevations. Head rugulosely punctate, 
flattened between the widely separated, rather prominent eyes; rostrum curved, stout, about as long as 
the prothorax, closely punctate, rugose and slightly widened at the base, the antenne inserted behind the 
middle, joints 1 and 2 of the funiculus subequal in length, the club ovate. Prothorax transverse, con- 
stricted and much narrowed in front, subtruncate at the base; densely, finely punctate, binodose on the 
disc, and somewhat flattened down the middle. Elytra much wider than the prothorax, subparallel in 
their anterior half, the humeri obliquely truncated ; punctate-striate, the punctures becoming much finer 
beyond the middle, the interstices ruguiose, 3-9 feebly convex, 3 swollen and fasciculate before the middle 
and also near the base. Beneath densely punctate. Mesosternum raised and very prominent, feebly 
emarginate. Legs rather slender, the femora unidentate. 
Length 6, breadth 3 millim. (9.) 
Hab. Mexico, ‘Toxpam in Vera Cruz (Salié). 
One specimen. Not unlike C. coriarius, but with the prothorax binodose and 
nigro-bivittate, the elytra with the third interstice raised towards the middle, the legs 
more slender, &c,
