CYRTOBARIS.— LITOBARIS. ATT 
1. Cyrtobaris bigibba, sp. n. (Tab. XXII. figg. 32, 32.) 
Black, opaque and alataceous above, the rostrum and abdomen shining; the punctures on the under surface 
and legs each bearing a very minute scale. Head finely punctate; rostrum (as seen in profile) arcuate 
above and flattened beneath, strigoso-punctate, smoother at the tip, the antenne inserted at about the 
basal third. Prothorax much broader than long, conical, transversely gibbous at the middle of the disc ; 
densely punctate. Elytra compressed at the sides anteriorly and rapidly narrowing thence to the broadly- 
rounded apex, transversely gibbous below the base ; finely punctate-striate, the stria becoming broader 
and more coarsely punctured anteriorly, the interstices broad, flat, narrowed towards the base, transversely 
rugulose, and faintly uniseriate-punctate. Beneath finely punctate. 
Length 2, breadth 1$ millim. (¢?) 
Hab. Panama, Bugaba (Champion). 
One specimen. 
LITOBARIS, gen. nov. 
Mandibles short, decussate; rostrum abruptly bowed from the base, separated from the head by a transverse 
groove, moderately long ; antennal club acuminate-ovate, densely pubescent ; prothorax feebly bisinuate 
at the base, the median lobe short; scutellum very small, rounded, free; elytra somewhat oval, conjointly 
rounded at the apex; pygidium very short, inflexed, ventrally exposed ; prosternum slightly depressed 
down the middle, without definite sulcus; anterior cox separated by less than their own width; legs 
short; femora unarmed; tibiew almost straight, feebly unguiculate; tarsi with the third joint narrowly 
bilobed, the claws connate at the base; body oblong, narrow, convex, sparsely clothed with minute 
scales. 
Type, L. subpruinosa. 
This genus is based upon a Mexican insect nearly related to Pseudobaris, with a 
short, inflexed, ventrally exposed pygidium, basally connate claws, an indefinitely 
grooved prosternum, and a feebly-lobed prothorax. Litobaris has very much the 
facies of Limnobaris confusa and its allies, from which it is readily separated by the 
exposed pygidium. repobaris has a similarly shaped prothorax, but differs in the 
form of the scutellum, &c. 
1. Litobaris subpruinosa, sp.n. (Tab. XXII. figg. 33, 33 a, 6, ¢.) 
Shining, nigro-piceous, the legs rufescent ; the punctures on the prothorax, elytral interstices, under surface, 
and legs each bearing a minute scale. Head closely, finely punctate ; rostrum moderately stout, a little 
longer than the prothorax, closely punctate at the sides, smooth along the centre above, the antenne 
inserted at about the middle. Prothorax transverse, gradually narrowing from near the base, feebly 
constricted in frout; densely punctate, with indications of a smooth median line. Elytra a little wider 
than the prothorax, subparallel at the base, the humeri obtuse ; shallowly punctate-striate (the punctures 
closely placed towards the base), the interstices broad, flat, the second and third confusedly, and the 
others densely and uniseriately punctate, the interstitial punctures rounded and coarser than those of the 
strie. Beneath closely punctate; first ventral segment flattened down the middle, the fifth almost on 
the same plane as the short. ventrally-exposed pygidium. Femora and tibie rugulosely punctured. 
Length 28, breadth 13 millim. (¢.) 
Hab. Mexico, “Sierra de Durango” (Zége, ex coll. Solart). 
One specimen. The elytral striae in this insect are narrow and shallow, and the 
interstices are densely and rather coarsely seriate-punctate.
