302 RHYNCHOPHORA. 
strongly transverse, the club short, ovate. Prothorax transverse, arcuately narrowing from the base, 
constricted in front; coarsely, densely punctate. Elytra gradually narrowing from the base, broadly 
rounded at the apex, somewhat flattened on the disc; narrowly striate, the interstices rugulosely 
punctate. Beneath densely punctate. Prosternum with a smooth, bare, flattened, triangular depression, 
limited on each side by an oblique ridge, the depression widening forwards and confluent with the sub- 
apical fove. Anterior coxe separated by half their own width. Legs rugosely punctate ; intermediate 
and posterior femora suleate beneath from near the base to the apex. 
Length 22-24, breadth 14-13 millim, (¢ 2.) 
Hab. Guatemaa, Capetillo and Guatemala city (Champion); Nicaragua, Managua 
(coll. Solari). 
Eight specimens from Guatemala and three from Nicaragua. The fine dark 
vestiture of the elytra is arranged in one or two rows down each interstice, the 
longer white scales being mostly placed along the alternate ones. Less convex than 
Zygobaris tristicula, the rostrum short, stout, and abruptly arcuate, the prosternal 
sulcus widening forwards to the transverse subapical groove, which is impressed with 
two fovee. 
2. Catapastinus cales, sp. n. 
Khomboid-ovate, moderately shining, black, the antenne ferruginous; sparsely clothed above with minute 
cinereous scales, those on the elytra closely placed in a single line along each interstice; the vestiture 
of the under surface and legs a little coarser and white. Head finely punctate, transversely grooved 
between the eyes; rostrum not longer than the head and prothorax, abruptly curved, rather stout, 
thickened and rugosely punctate at the base and for the rest sparsely, finely punctate, the antennz 
inserted behind the middle, the antennal club ovate, small. Prothorax transverse, narrowing from the 
base, constricted in front; coarsely, densely punctate, except along a narrow smooth median space. 
Elytra narrowly striate, the interstices each with a single row of closely-packed coarse shallow 
punctures which becomes double at the base. Beneath densely, the abdomen more sparsely, punctate. 
Prosternum almost unimpressed behind the transverse groove, which is distant from the apical margin. 
Anterior coxe separated by half their own width. Legs rugosely punctate; intermediate and posterior 
femora sulcate beneath. 
Length 24, breadth 12 millim. (@.) 
Hab. Costa Rica, Higuito, Pacific slope (Biolley). 
One female, labelled as having been found on Calea avillaris, a Composite plant. 
Very like Zygobaris tristicula, but less convex, the rostrum (2) much shorter, more 
abruptly curved, and smoother, the head distinctly punctate, the antenne ferruginous 
and with a smaller club; the elytra more finely striate, the prosternum almost 
unimpressed and with the transverse groove placed much nearer the coxe, &c. The 
upper surface is less densely punctate than in C. casey. 
3. Catapastinus alternans, sp. n. 
thomboid-ovate, broad, flattened above, shining, black; the sides of the prothorax, the under surface, and 
legs somewhat thickly clothed with narrow, hair-like, white scales, the elytral interstices 1, 3, 5,7, and 9 
each set with a scattered series of adpressed, white, setiform scales (which are clustered into small spots 
at the base) intermixed with a few minute pallid scales, the punctures on the other interstices also 
bearing minute scales. Head finely punctate, with a deep transverse groove between the eyes ; rostrum 
not longer than the head and prothorax, abruptly bowed downwards from the base, rather stout,
