ZYGOBARIS.—CATAPASTINUS. 331 
legs and under surface also clothed with scattered white scales. Head almost smooth, with a deep 
transverse groove between the eyes; rostrum stout, curved, usually more or less constricted at the base 
beneath, in the @ as long as the elytra, in the ¢ a little shorter, in both sexes striate and rather 
coarsely punctate to near the tip, the antenne inserted at about the middle in the g and nearer the 
base in the 9, the antennal club ovate. Prothorax transverse, arcuately narrowing from the base, 
constricted in front; coarsely, densely punctate. Elytra rather short, rounded-triangular, depressed 
along the suture at the base; coarsely punctate-striate, the striae narrow, the interstices finely alutaceous 
and roughly uniseriate-punctate. Beneath coarsely, the abdomen sparsely and more finely, punctate ; 
ventral segment 1 depressed down the middle, and 5 shallowly foveate, in the g. Prosternum shallowly 
depressed anteriorly, the depression limited on each side by an oblique ridge and terminating in a fovea 
in the subapical groove. Tibiw in the ¢ strongly, in the ? feebly, unguiculate. 
Var. Duller, the vestiture more abundant, above and beneath, the elytral interstices each with a row of 
hair-like white scales, 
Length 21-24, breadth 1,,-12 millim. (3 9.)

Sent us in numbers from Mexico; the variety is represented by three specimens from 
Ventanas. The rostrum varies in length, but it is always elongate in the female, 
and in both sexes the puncturing extends to near the tip. A male from Capetillo, 
apparently belonging here, is narrower than the specimens described, and has the 
prothorax subconical and the ventral depressions deep. The scattered white scales on 
the elytra are smaller than in the North-American species of the genus. 
CATAPASTINUS, gen. nov. 
Rostrum stout, strongly arcuate, not longer than the head and prothorax, separated from the head by a 
transverse groove; mandibles curved, short, decussate; antennal club ovate; prothorax more or less 
tubulate in front, the apical portion very short ; scutellum free; elytra much wider than the prothorax, 
rounded-triangular, narrowly striate; pygidium not visible; prosternum considerably developed behind 
the coxe, unarmed, triangularly excavate, the excavation widening forwards and sometimes shallow, 
the transverse subapical groove placed midway between the cox and apex and impressed with two more 
or less distinct fovese ; legs short; femora stout, sulcate or not beneath; tarsal claws small, connate 
at the base ; body rhomboid-ovate, sparsely squamose. 
Type, C. casey?. 
The type of this genus is nearly related to both Catapastus and Zygobaris, but 
it has the prosternal depression sharply-defined and widening forwards (instead of 
backwards), this, however, being indistinct in C. calew and C. alternans, and wanting 
the oblique ridge on each side. The rostrum is short, as in Catapastus, and separated 
from the head by a transverse groove, as in Zygobaris. 
1. Catapastinus caseyi, sp.n. (Tab. XVII. figg. 15, 154, 4, 3.) 
Rhomboid-ovate, black; somewhat thickly clothed with small, narrow, blackish or fuscous scales intermixed 
with a few longer setiform white scales, the scales on the elytra seriately arranged and the white ones 
mostly confined to the alternate interstices; the vestiture of the legs and under surface rather sparse, 
fine, and white. Head finely punctate, transversely grooved between the eyes; rostrum very stout, 
- abruptly arched from the base, not longer than the head and prothorax, striate and thickly punctate, 
smoother at the tip in the 2, the antenne inserted at the middle, the outer joints of the funiculus
