410 RHYNCHOPHORA. 
humeri; finely punctate-striate, the second and third strie sinuous, the interstices alutaceous, closely 
punctate, flat, 5 raised into an oblong hump at its point of termination. Pygidium densely punctate. 
Beneath closely and coarsely, the ventral segments very sparsely and finely, punctate, 1 and 2 with a 
depressed fulvo-pilose space down the middle, and 5 with a truncated prominence in the centre at the 
apex, inthe ¢. Prosternum as in ZL. acnisti. Anterior coxe narrowly separated. 
Var. The velvety-black patch on the middle of each elytron reduced to a streak on the third interstice, the 
larger pallid scales wanting. 
Length 23-34, breadth 13-18 millim. .(d 2.) 
Hab. Guatemata, El Tumbador, Zapote, Capetillo, Duefias (Champion); Panama, 
Volcan de Chiriqui (Champion). 
Numerous examples. The form selected as typical (fig. 18) is from the Pacific slope 
of Guatemala, the other from Chiriqui. Smaller and less elongate than L. acnisti ; 
the prothorax abruptly constricted in front, and with two large triangular patches of 
black scales on the basal half of the disc; the elytra much shorter, with the dorsal 
strie sinuous and the black patches reduced in size. The male-characters are similar 
in the two species. 
3. Lepidobaris bifasciculata, sp.n. (Tab. XX. figg. 19, 19a, 3.) 
d. Elongate, rather narrow, depressed, opaque, the abdomen shining, black, the antenne, tip of the rostrum, 
and tarsi ferruginous; the head avd rostrum, the prothorax above (especially along the median line) and 
beneath, the scutellum, the apex of the elytra, pygidium, the third and fourth ventral segments at the 
sides and the fifth at the apex, and the legs, sparsely clothed with long, coarse, narrow, ochreous scales, 
some of those near the apex of each elytron erect and clustered into a dense prominent fascicle, the rest 
of the surface almost bare. Head closely punctate, squamose above ; rostrum not longer than the head 
and prothorax, moderately stout, gibbous at the base, rugulosely punctate and squamose to the tip. 
Prothorax narrow, transverse, subcylindrical, constricted in front; closely punctate, except along an 
oblong space near the margin. Elytra long, somewhat widened posteriorly, flattened, transversely 
depressed on the disc below the base and near the middle, the humeri not prominent; very finely and 
shallowly punctate-striate, the interstices densely alutaceous, faintly uniseriate-punctate, flat, the fifth 
swollen into an oblong hump at its point of termination, the third with a compressed tuberculiform 
prominence near the apex. Pygidium densely punctate. Beneath closely and coarsely, the ventral 
segments very sparsely and finely, punctate, 1 and 2 with a densely punctate, ochreo-pilose excavation 
extending down the middle, 5 truncate in the centre at the apex. Prosternum slightly hollowed behind 
the transverse subapical groove. Anterior coxe narrowly separated. 
Length 42, breadth 12 millim. 
Hab. Panama, Volcan de Chiriqui (Champion). 
One male. In this insect the long, narrow ochreous scales on the elytra are almost 
entirely placed on the apical fourth, and there mainly clustered into a prominent, 
spiniform fascicle, while those on the prothorax are condensed into a median line. 
4, Lepidobaris latisquamis, sp. n. (Tab. XX. figg. 20, 20 a, b, 2.) 
Oblong, shining, the prothorax beneath and the sternal side-pieces opaque, black, the antenne and tarsi more 
or less ferruginous; the rostrum albo-squamose at the base; the prothorax clothed with coarse, inter- 
mixed, adpressed ochreous or whitish and semierect black scales, the pallid scales mainly condensed into 
a dense, sharply-defined, sinuous vitta on each side and an interrupted median line : the elytra with 
- intermixed subseriately arranged, oblong blackish (or brown) and irregularly distributed, very large, fan-
