MEMOIRS ON THE COLEOPTERA
Aneflus Lee.
The antennae in this genus become much more flattened distally
than in the preceding three genera, with a convex ridge along the
median line of the outer joints, but without trace of the dorsal
carina of the subbasal joints observable in A neflomorpha. The size
of the body is also very much greater. Besides the type described
as Elaphidion protensum by LeConte, the genus will probably
include Elaphidion fuchsi Wick. (Can. Ent., 1905, p. 170), as well
as Aneflus prolixus Lee. (Sm. Misc. Coll., 263, 1873, p. 203). The
following species seems to be allied to prolixus:
Aneflus cochisensis n. sp. Very elongate, moderately slender, very
dark piceous-brown throughout, covered uniformly with rather coarse and
decumbent, close-set whitish hairs, without erect hairs, except toward the
sides, more notably of the head and prothorax; head densely rugose, with
a fine abrupt striiform canaliculation; antennae (cf) extending to apical
fourth or fifth of the elytra, rather stout, compressed, densely, finely
pubescent, with short decumbent pale hairs, the second joint anchylosed
with the third, as long as wide, third much longer than the fourth but
only just visibly longer than the fifth, swollen at tip and with a short and
very stiff diverging spine, the carina of the distal joints very obtuse,
convex, the apical process of the last joint abruptly narrowed, parallel;
prothorax cylindric, very slightly elongate, parallel and but slightly
uneven at the sides, very coarsely, densely and confluently punctate,
with a small irregular callus on the middle line at outer fifth, a small and
more anterior, less lateral tubercle and a minute callus in the same line
near the base, also with a narrow, very irregular callous median line for a
short distance behind the centre; scutellum finely, closely pubescent,
with a polished nude median line; elytra not quite four times as long as
the prothorax and almost one-half wider, three times as long as wide,
parallel and very straight at the sides to the conjointly semicircular
apex, each with a small shallow apical sinus, the sutural spine short but
slender, the outer obtusely dentiform ; surface irregularly but rather loosely
punctured, very coarsely so basally, finely and obscurely distally, each
having two broad feeble raised discal lines; legs moderate; femora not
spinose; fifth ventral (c? 1
) much shorter than the fourth, broadly sinuate
at tip, the lateral angles well defined; palpi stout, the last joint of the
maxillary nearly as long as the two preceding, twice as long as wide, obliquely
arcuate at tip. Length (cf ) 26.0 mm.; width 5.8 mm. Arizona

A single male sent to me under the name Aneflus protensus Lee.
It differs from protensus, 'which is a native of Sonora, Mexico, in its
cylindric, parallel and not anteriorly and posteriorly narrowed pro-
thorax, which is said to be subangularly rounded at the sides in that
species, in the absence of transverse pronotal plications, in the
