1. Anthonomus furcatus, sp. n. (Tab. IX. figg. 17, 17a, 3; 176, pygi- 
dium, 3.) 
Oblong-ovate, rather broad, robust, nigro-piceous, the antenne, knees, and tarsi partly ferruginous ; somewhat 
thickly and uniformly clothed with a fine fulvous-brown pubescence, the elytral interstices each with a 
row of scattered, fine, short, decumbent white sete. Head rugulose, foveate above the eyes, the latter 
prominent; rostrum curved, a little longer than the head and prothorax, rugulose and 5-carinate, 
sparsely punctate and shining at the tip, the antenne inserted at about one-third from the apex, joint 1 
of the funiculus twice as long as 2. Prothorax broad, strongly transverse, rounded at the sides, abruptly 
narrowed aud constricted in front, bisinuate at the base, densely, very finely punctate. Elytra oblong, 
gibbous, nearly one-half wider than the prothorax, the humeri rounded and not prominent; rather 
coarsely punctate-striate, the interstices convex and rugulose, 1—7 each with a row of scattered rounded 
ot oblong prominences. Pygidium exposed, vertical, strongly transverse, and produced on each side into 
a long, flattened, somewhat curved, truncated process. Fifth ventral segment broadly and very deeply 
emarginate. Legs very stout; anterior femora strongly bidentate, the intermediate and hind femora each 
with a single stout tooth and a minute additional one exterior to it, the anterior pair strongly clavate ; 
tibiee deeply sinuate on their inner edge (appearing triangularly dilated), the anterior pair bowed; tarsal 
claws with a long tooth. 
Length 34-34, breadth 17-2 millim. (<¢.)

Two males. This extraordinary insect will probably have to be removed from 
Anthonomus when the female is discovered. Dietz, however, includes in that genus 
one N.-American species, A. (Coccotorus) scutellaris, Lec., with an exposed pygidium 
and a somewhat similarly shaped fifth ventral segment in the male. The furcate 
process on each side of the pygidium is a very remarkable character.
