CATAPASTINUS.—CATAPASTUS. 333 
compressed, rugulosely punctate, and subcarinate, the apical half flattened and striato-punctate. 
Prothorax transverse, arcuately narrowing from the base, constricted in front; sparscly, finely punctate, 
except along a narrow space down the middle, the punctuation becoming coarser and confluent at the 
sides. Scutellum transverse. Elytra considerably wider than the prothorax, narrowing from the 
rounded humeri; narrowly punctate-striate, the interstices broad and flat, 2 bi-, and the others uni-, 
seriately asperato-punctate. Beneath densely, the abdomen more sparsely, punctate. Prosternum 
shallowly sulcate, the groove terminating in a transverse bifoveate depression in front. Anterior 
coxee separated by about their own width. Legs rugosely punctate ; femora sulcate at the apex only 
beneath; tibicee feebly unguiculate. 
Length 3, breadth 14 millim. (2.) 
Hab. Mexico, Acapulco (/ége). 
One specimen, somewhat worn. A broad, shining black form, with a row of 
setiform white scales on each of the alternate elytral interstices, the sides of the 
prothorax and the under surface also sparsely clothed with narrow white scales. The 
broadly produced portion of the prosternum almost covers the mesosternum.

Two N.-American species were included under Catapastus by Casey and two others 
were subsequently added by Linell. The one now described possesses all the structural 
characters of the genus*. These insects are nearly related to Zygobaris, but have 
a short stout rostrum. The tarsal claws are small and connate. 
1. Catapastus ruficlava, sp.n. (Tab. XVII. figg. 16, 164, 6, ¢ .) 
Rhomboidal, narrow, black, the antennal club ferruginous; somewhat thickly clothed with rather coarse, 
narrow, whitish scales, the scales on the prothorax long and closely adpressed (fig. 16 6), those on the 
elytra arranged in a single line down each interstice, 2 and 3 with two lines on the basal half; the 
under surface set with larger white scales, the prosternum densely squamose in the ¢. Head squamose 
and densely punctate; rostrum strongly arcuate, very stout, short, in the ¢ scarcely so long as the 
head and prothorax and densely punctate and squamose to the tip, in the 2 with the apical halt 
bare and somewhat flattened, the antenne inserted at (@) or beyond (¢) the middle, the club ovate. 
Prothorax transverse, conical, densely, confluently punctate. Scutellum sparsely squamose. Llytra 
subtriangular, finely punctate-striate, the interstices closely punctulate. Beneath densely punctate. 
Prosternum excavate down the middle from the transverse subapical groove, the excavation limited on 
each side by an oblique ridge to as far as the anterior coxe. Legs short; femora more or less sulcate 
beneath. 
Length 2-23, breadth 1-145 millim. (d @-) 
Hab. Mexico, Ventanas in Durango (Hége); GuaremaLa, Capetiilo (Champion) ; 
Nicaragua, Managua (Solari). 
Five specimens, three of which are from Guatemala. The vestiture of this insect 
is coarser, whiter, and more uniform than in C. conspersus (Lec.), examples of which 
have been communicated by Capt. Casey and Mr. Wickham. 
* Mr. Wickham has sent me a very similar unnamed form from Brownsville, Texas, and we are indebted 
to the Director of the U.S. Nat. Museum for an example of C. signatipennis, Linell, from Florida.
