142 RHYNCHOPHORA. 
One specimen. Very like the smaller examples of H. coronatus, but with the short 
sharp dorsal carine of the prothorax oblique (not parallel), the prothorax itself less 
constricted in front, the elytra more finely punctate-striate, the femora without trace 
of tooth, the intermediate tibiz not subangularly dilated near the base. 
5. Hypoceeliodes gibbicollis, sp.n. (Tab. VIII. figg. 30, 304, ¢ .) 
Short, broad, subrhomboidal, black, the antenne, anterior margin of the prothorax, apical margin of the elytra, 
knees, tibie, and tarsi rufo-testaceous; variegated above with small cinereous and pale brown scales, the 
latter mostly crowded into a broad irregular space along the suture, the cinerous scales on the elytra con- 
densed into interrupted undulate fascie, the mesothoracic epimera with an ochreous patch. Head rugulosely 
punctate, depressed between the eyes; rostrum arcuate, moderately stout, not longer than the prothorax, 
rugulosely punctate. Prothorax rapidly narrowing forwards, the anterior portion narrow and tubulate ; 
finely punctate, the dise gibbous, canaliculate, and with two short, very prominent, oblique caring, the 
lateral tubercles acute. Elytra broad, rounded-triangular ; finely punctate-striate, the interstices rugulose, 
the alternate ones raised. Metasternal excavation deep, reaching to a little beyond the middle coxe. 
Fifth ventral segment of the ¢ excavate at the sides and transversely depressed in the middle, appearing 
binodose when viewed from behind, Legs short; posterior femora moderately incrassate ; tibie rather 
slender, the intermediate pair unguiculate at the inner apical angle in the ¢. 
Length 13, breadth 14 millim. (d @.) 
Hab. Mexico, Teapa (H. H. Smith). 
One pair. Smaller than HZ. phytodioides, with still more prominent dorsal elevations 
on the prothorax and acute lateral tubercles, the brownish scales on the elytra mostly 
condensed along the suture, the legs more slender. The humeri are more prominent 
than in H. wickhamt, and the prothoracic elevations very conspicuous. 
6. Hypoceliodes pulvereus, sp.n. (Tab. VIII. figg. 31, 31a, ¢.) 
Short ovate, piceous or rufo-piceous, the antenne ferruginous; mottled with minute whitish and brown scales, 
which are in part hidden by a fulvous waxy secretion, the vestiture coarser beneath. Head rugulosely 
punctate, finely carinate on the vertex, flattened between the eyes, which are separated by the width of 
the rostrum; rostrum long, arcuate, reaching the apex of the metasternum, in the ¢ stout, rugosely 
punctate and sharply carinate to near the tip, with the apex only smooth, in the Q much more slender, 
and shining and almost smooth throughout. Prothorax finely punctate, the lateral tubercles well- 
developed, the disc with two similar tubercles, separated by the shallow median sulcus, Llytra short, 
rounded at the sides; rather coarsely punctate-striate, the interstices rugulose, the alternate ones 
strongly, the others feebly, convex. Meso- and metasternal excavations broad and shallow. Ventral 
segments 1 and 2 flattened, and 3-5 hollowed, down the middle, and 2 and 5 slightly binodose at the 
apex, in the ¢. Legs short and stout; posterior femora strongly incrassate, the anterior and inter- 
mediate pairs obsoletely dentate ; intermediate and posterior tibie unguiculate at the inner apical angle 
in the ¢. 
Length 2-23, breadth 13-12 millim. (¢ @.) 
Hab. Panama, Bugaba, Volcan de Chiriqui, Tolé (Champion). 
Nine specimens. The almost smooth and comparatively slender rostrum of the 
female, the sulcate ventral segments 3-5 of the male, and the rather sparse mottled 
vestiture of the upper surface distinguish JZ. pulvereus.
