476 ' RHYNCHOPHORA. 
anterior coxw separated by less than their own width; legs short ; femora sulcate, the anterior pair 
with a broad, deep, subapical excavation limited inwards by a short tooth (fig. 31); tibiee more or less 
curved, strongly unguiculate; tarsi short, the claws minute, connate at the base ; body oblong-ovate, 
polished and glabrous above. 
Type, 7’. cavimanus. — 
The minute species placed under this genus is related to Pseudobaris, but cannot 
possibly be included in it. The bifoveate, sulcate prosternum, the minute, basally 
connate tarsal claws, the somewhat bowed tibiz, the deeply excavate, feebly dentate 
anterior femora, and the small, oblong-ovate antennal club are its chief characters. 
Tytthobaris approaches Nanobaris, but differs from it in the form of the claws, tibie, 
and femora, the narrower antennal club, the bifoveate prosternum, &c. Jicrobaris, 
Casey, including a single species from Texas, seems to be an allied genus. 
1. Tytthobaris cavimanus, sp.n. (Tab. XXII. figg. 31, 81a, 6, 2.) 
Black, shining, glabrous above, the punctures on the under surface and legs each having a minute scale. Head 
minutely punctate; rostrum closely punctate, smoother at the tip. Prothorax rather convex, a little 
broader than long, gradually narrowing from near the base, feebly constricted in front; closely, coarsely 
punctate, smoother along the anterior margin. Elytra subparallel in their basal fourth, about twice as 
long as the prothorax, transversely depressed on the outer part of the disc below the base, the suture 
depressed anteriorly; very finely punctate-striate, the stria becoming broader and strongly punctured at 
the base, the interstices broad, flat, each with a row of very minute scattered punctures. Beneath closely 
and coarsely, the abdomen very sparsely and finely, punctate. Intermediate tibie strongly, the others 
more feebly, arcuate. 
Length 2;4,, breadth 1 millim. ( 9.) 
Hab. GuaTEMALA, San Juan in Vera Paz (Champion). 
One specimen, easily recognizable by the coarsely-punctured prothorax, the polished, 
finely striate elytra, the bowed intermediate tibiz, and the toothed, broadly excavate, 
anterior femora, the tooth arising nearer the base than usual amongst the Barids. 
CYRTOBARIS, gen. nov. 
Rostrum very stout, abruptly bowed from the base, as long as the prothorax, separated from the head by a 
deep transverse groove; antenne with a densely pubescent, elongate-ovate club, which is nearly as long 
as the funiculus, the joints 2-7 of the latter closely articulated, widening outwards, and strongly trans- 
verse; prothorax deeply sinuate at the base, the median lobe subtruncate; scutellum small, oblong, free ; 
elytra very broad, short, rounded-triangular, conjointly rounded at the apex; pygidium short, strongly 
transverse, vertical ; prosternum shallowly sulcate, deeply bifoveate anteriorly ; anterior coxe separated 
by a little less than their own width, flattened within; intermediate coxw widely separated ; legs short, 
stout; femora compressed, unarmed, sulcate ; tibie almost straight ; tarsi with the third joint broad and 
bilobed, the fourth slender, the claws minute, subconnate at the base; body short, rhomboid-ovate, 
subglabrous. 
Type, C. bigibba. 
This genus is perhaps nearest related to Nancbaris. It includes a single species, of 
small size, from Panama.
