150 RHYNCHOPHORA. 
3, 5, and 7 interruptedly costate, and each of these angularly raised at the -base, the prominence on 7 
forming a conspicuous humeral callus, the suture also a little raised before the middle. 
Length 33-43, breadth 2-23 millim. (@.) 
Hab. Mexico (Sallé), Teapa (H. H. Smith). 
‘Five specimens. 
2. Achia adusta, sp. n. (Tab. IX. fig. 8, 3.) 
Ovate, convex, closely rugulose, opaque, piceous or rufo-piceous, the tip of the rostrum, the antenne, the base 
of the intermediate and hind femora, the tibie, and tarsi more or less testaceous ; densely clothed with 
greyish-ochreous pubescence, the prothorax with a darker patch on each side of the disc, leaving a pale 
median vitta, the elytra with a large, common, rhomboidal, fulyous or obscure ferruginous patch at the 
base, this being streaked with brown in one specimen, the pubescence of the under surface pale. Rostrum 
cylindrical, a little longer than the head and prothorax, rugulose, carinate down the middle in the ¢; 
antenne in the ¢ inserted near the tip of the rostrum, in the 9 at about two-fifths from the apex, 
joint 1 of the funiculus elongate, nearly twice as long as 2. Prothorax transverse, strongly constricted 
anteriorly, the sides rounded at the middle and almost parallel behind. Elytra convex, much wider than 
the prothorax, subparallel in their basal half, the humeri rounded and rather swollen; finely punctate- 
striate, the interstices feebly convex, 1, 3, and 5 interruptedly costate at the base. 
Length 3-34, breadth 14-13 millim. (¢ @.) , 
Hab. Mexico (Sallé). 
One pair. Smaller, narrower, and less robust than A. rhombifera, the elytra sub- 
parallel in their basal half, the rhomboidal patch not extending on to the prothorax. 
3. Achia discifera, sp.n. (Tab. IX. fig. 9, ¢.) 
Ovate, densely rugulose, opaque, rufo-piceous, the antenne, the tibive and tarsi in part, and the base of the 
intermediate and hind femora ferruginous or testaceous, the rostrum black at the tip; thickly clothed 
with greyish-ochreous pubescence, that on the head, rostrum, prothorax, and under surface coarser and 
squamiform ; the elytra with a large, common, transverse, oval, brownish-ferruginous patch at the base, 
this being streaked with ochreous on the third interstice, the other portion thence to the apex slightly 
mottled with fuscous. Rostrum scarcely as long as the head and prothorax, cylindrical, bare and shining 
at the tip, the antenne inserted at about one-third from the apex, joint 1 of the funiculus twice as long as 2, 
4" transverse. Prothorax broader than long, moderately constricted anteriorly. Elytra convex, much 
wider than the prothorax, rounded at the shoulders; finely punctate-striate, the interstices feebly convex, 
3 raised at the base. 
Length 24, breadth 13 millim. (3.) 
Hab. Panama, Bugaba (Champion). 
One specimen. Smaller than A. adusta, the rostrum shorter, the prothorax less 
constricted before the middle, the elytra with the humeri less prominent, the common 
transverse patch oval in shape, the third interstice feebly raised at the base. Allied 
forms occur in South America. 
CIONOPSIS, gen. nov. 
Head exserted, subconical, the eyes rounded, moderately prominent, distant from the anterior margin of the 
prothorax ; antenne (<) inserted near the apex of the rostrum, the funiculus 7-jointed, the club ovate ; 
rostrum moderately long, cylindrical, the scrobes lateral, shallow ; prothorax transverse, constricted and
