J)IIDAMUS Dillon and Dillon, gen. nov.
The distinguishing characters of this genus are the more oblong
form of body; front broad, nearly as wide as long, very slightly
narrowed below eyes ; eyes with lower lobe ovate, small, subequaJ
in height to the gena j pronotum cylindrical, sides distinctly excavated,
disk with five tubercles; elytl'a with base rugosely punc·
tate, without granules j meso· and metatibiae expanded in male.
Moderate-sized, elongate·ovate, robust. Head with front nearly as broad as
long, sides parallel, very slightly narrowed below eyes; geM elongate; eyes with
lower lobe ovate, subequal in height to gena; antennal tubercles promillent, well
separated, only very feebly produced at apex in mnle, not at all in femalc. Pro­
notum transverse, cylindrical, sides excavated medially, vrith n small tubercle just
above angulation of procoxae, apex narrower than basc; disk with five small but
distinot tubercles. Scutellum transverse. Elytra feebly widened at middle, apices
separately rounded ; disk at base more or less rugosely punctate, without distinct
granules; basal gibbosities broad, feebly elevated; humeri prominent, angle with n
feeble, obtuse tubercle. Presternum simple, narrow, widened behind middle; meso­

PLATE IX, FIGURE 12.
Closely allied to Esonius panopus but differing in that the base
of elytra is simply punctate; pronotum with sides excavated, lateral
tubercle more ventral ; eye subequal to gena, only very feebly
elongate.
MALE. Elongate-ovate, robust, subconvex; dark reddish-brown to fuscous.
Head with pubescence which va.ries from a tawny-gray or brownish.gray to ocb·
raceous ; front slightly variegated with dnrk brownish-gray, the basic pubescence
