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, ob- 

 liquely 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
