BUSCKLA.—CHRYSOBARIS. 45D 
Beneath closely punctate, the first ventral segment broadly flattened in the middle in the d, the 
pygidium sloping ventrally and not visible from above. 
Length 53-53, breadth 3-33 millim. (¢ 2.) 
Hab. Panama, Boqueron, 60 miles south of Tabernilla (Busch, in U.S. Nat. Mus.). 
Numerous examples, kindly communicated by the Director of the Smithsonian 
Institution for description. 
CHRYSOBARIS, gen. nov. 
Mandibles short, decussate; rostrum separated from the head by a transverse groove, stout, strongly, abruptly 
arcuate, moderately long, the antenne inserted at or near the middle, the antennal club ovate, densely 
pubescent, and rather small; prothorax deeply sinuate at the base ; scutellum small, free, rounded; elytra 
angularly produced at the apex; pygidium exposed, subvertical, strongly transverse; prosternum with 
two fovee in the transverse subapical groove, and a fine longitudinal ridge extending down from them 
exteriorly to the cox, the median space slightly hollowed; anterior coxw separated by about their own 
width ; legs short; femora unarmed, sulcate; tarsi slender, with third joint narrowly bilobed, the claws 
long, subconnate or narrowly separated at the base; body oblong-ovate, metallic, setulose or glabrous above. 
Type, C. plurisetosa. 
The three small species placed under this genus have the elytra, &c., formed as in 
Pseudobaris acutipennis and its allies, but they cannot be satisfactorily treated as 
congeneric, on account of the bifoveate, feebly sulcate prosternum and the abruptly 
bowed rostrum. C. plurisetosa has a somewhat dense setiform vestiture; the other 
two species are glabrous and very rugose above, and have a longer dentiform prominence 
at the apex of each elytron. 
1. Chrysobaris plurisetosa, sp.n. (Lab. XXII. figg. 5, 5a, b, 2.) 
Somewhat convex, very finely alutaceous, moderately shining, eneous or cupreo-2eneous ; the upper surface 
clothed with rather long, adpressed, pallid or golden, setiform scales, which are condensed into one or two 
dense lines down each elyral interstice (fig. 55), the vestiture sparser and finer beneath. Head closely 
punctate, deeply, transversely grooved between the eyes; rostrum about as long as the head and pro- 
thorax, abruptly bowed from the base, densely punctate, smoother at the tip, the antenne inserted at a 
little behind the middle. Prothorax transverse, gradually narrowing from the base, feebly constricted 
in front; densely punctate, with indications of a smooth median line. Scutellum rugose. Elytra wider 
than the prothorax, gradually narrowing from the rounded humeri, angularly produced at the apex ; 
finely punctate-striate, the interstices broad, flat, transversely rugulose, and closely, finely uniseriate- 
punctate, the third somewhat confusedly produced. Beneath very coarsely, the ventral segments sparsely 
and finely, punctate. Prosternum with a transverse, posteriorly widened, sharply-defined excavation in 
front, enclosing the two deep fovew. Femora coarsely punctate. 
Length 22-23, breadth 14-11 millim. (9 .) 
Hab. Guatemata, Guatemala city, Capetillo (Champion). 
Two specimens. 
2. Chrysobaris corrosa, sp.n. (Tab. XXII. figg. 6, 64, 3.) 
AEneo-cupreous, the tip of the rostrum greenish, moderately shining, subglabrous. Head densely, rugulosely 
punctate, shallowly, transversely grooved between the eyes; rostrum about as long as the head and 
prothorax, densely, rugulosely punctate, much smoother at the tip, the antenne inserted at the middle.
