246 RHYNCHOPHORA. 
Hab. Costa Rica (Biolley, in coll. Solart). 
One specimen, doubtless somewhat immature. An isolated form, with the rostrum 
sharply separated from the head above and beneath, gibbous, and broadly excavate at 
the sides; the prothorax with coarse scattered punctures; the anterlor coxe narrowly 
separated; the upper surface very sparsely setose. 
LAMPROBARIS, gen. nov. 
Rostrum strongly arcuate from the base, cylindrical, at least one-half the length of the body, the antenne 
inserted at (2) or beyond (3) the middle, the antennal club oblong-ovate and acuminate; mandibles 
short, slightly notched on their inner edge, feebly decussate; prothorax conical, tubulate in front, the 
upper anterior portion subcucullate ; scutellum small, free; elytra triangular, much wider than the 
prothorax, flattened on the disc, abruptly suleate on the apical declivity; pygidium not visible; 
prosternum bispinose and often excavate in the 6, flattened or shallowly excavate in the 9 ; ventral 
segments 1 and 2 connate at the middle; anterior coxe separated by about half their own widths 
femora feebly clavate, unarmed; tibie and tarsi rather slender, the lobes of the third tarsal joint narrow, 
the tarsal claws long and divergent; body rhomboidal, polished, glabrous above and beneath. 
Type, LZ. cucullatus. 
Two closely allied forms are referred to this genus. Both have the elytra abruptly 
sulcate at the apex (as in Lvssobaris nigropiceus); the legs long and rather slender, 
smooth or sparsely punctate; and the short tubulate portion of the prothorax 
somewhat produced over the head above. 
1. Lamprobaris cucullatus, sp.n. (Tab. XIV. figg. 2, 2a, 3.) 
Rhomboidal, ferruginous, shining. Head minutely punctate ; rostrum reaching nearly or quite to the apex 
of the metasternum, finely punctate, smoother along the middle. Prothorax transverse, narrowed from 
the base, smooth. Scutellum somewhat rounded, flat. Elytra rapidly narrowed from the base, conjointly 
rounded at the apex, with smooth, somewhat swollen humeri; sharply striate, the strie obsoletely or 
feebly punctate, the interstices smooth, flat on the disc and strongly convex on the apical declivity. 
Prosternum and propleura smooth, the rest of the under surface sparsely punctate. Legs almost 
smooth. 
¢. Prosternum armed with two spines of variable length, and in fully-developed examples with a very deep 
excavation between them ; first ventral segment slightly depressed down the middle, 
Length 3-31, breadth 13-2 millim. (¢ 2.) 
Hab. GuatTEemaALa, Sinanja and Purula in Vera Paz, Cerro Zunil (Champion: 3 2); 
Panama, Bugaba (Champion: 2). 
Kight specimens, the single specimen (¢ ) from Panama having the rostrum black 
at the apex, and also longer and more closely punctate than in those of the same sex 
from Guatemala. 
2. Lamprobaris rufonotatus, sp. n. (Tab. XIV. figg. 3, 3a, .) 
Rather elongate, rhomboidal, shining, black, the anterior lobe of the prothorax, a humeral spot and a large 
apical patch on the elytra, the antenne, prosternum, prosternal spines, tibie, tarsi, and base of the 
femora, rufous or ferruginous, the head and rostrum rufo-piceous. Head very minutely punctate ; 
rostrum reaching the apex of the metasternum, punctured at the sides, smooth along the midile,
