The simple claws, covered pygidiiim and short third and fourth ven- 
tral segments, may be considered valid reasons for placing it near 
Erirrhinns. The formation of the antenme and the general habitus 
are distinctly Anthonomid. It forms a transition from the present 
tribe to the Erirrhinini. 
A. diibiH!^ n. sp. Plate vii, figs. 34 — 34«. — Elongate-oval, pitcliy-black and 
almost imperceptibly pubescent : the beak is striate and punctured, the striae 
extending from the base to about the middle. Head finely punctured. Protho- 
rax finely punctured, more densely on the .sides with an ill-defined, smooth, 
dorsal line; the elytral striae are fine, punctures moderately large and rather 
close set; interspaces nearly flat, irregularly puuctulate ; underside punctured, 
distal end of tibiae and the tarsi, rufo-piceous. Long. 3.2 mm.; .13 inch.

Beak rather short and robust, cylindrical, and nearly straight ; 
subcarinate. Scrobes oblique, wide and deep, impinging against the 
lower segment of the eyes. Antenme moderate, scape short, incras- 
sate at apex; funicle 7-jointed, first joint stout, outer joints wider; 
club oval, pubescent, first joint longer than usual. Eyes large, 
transversely oval, moderately convex. Head punctured, densely 
jiubescent between the eyes. Prothorax wider than long, narrowed 
in front, rounded on the sides; base nearly straight; surface punc- 
tured. Elytra elongate, wider at base than the prothorax, slightly 
dehiscent at the apex and concealing the pygidium ; striie and punc- 
tures moderate ; middle coxie narrowly separated by the mesoster- 
num ; metasternum as long as the fir.st ventral segment ; v^entral 
segments unequal, third and fourth short, united about as long as the 
second segment, fifth long, rounded; sutures, except the first, bent 
slightly backward at the sides. Legs moderately long and somewhat 
stout ; thighs clavate; tibiae not slender, middle and posterior widened 
towards the apex, all unguiculate ; tarsi rather stout, third joint 
broadly bilobed ; claws appendiculate. The fifth ventral segment 
of male is carinate near the ti]). 
Lacordaire ])laced this genus among his Tychiides, on the ground 
that the 2-4 ventral sutures are slightly bent backward at the sides. 
Its nearest ally in the present tribe is Alycodes.
