ART. 18 NEW ISrOETH AMEEIOA57 WEEVILS CHITTENDEN 15 



Elytra much wider at base than prothorax, humeri gradually ob- 

 tusely rounded, rather prominent; sides subparallel in basal three- 

 fourths, apical fourth narrowed, apices scarcely separated. Third 

 intervals strongly elevated for a short distance at base, the two some- 

 what convergent ridges thus formed enclosing the subdeltoid, nearly 

 flat post scutellar impression ; between the ridge on third interval and 

 the feeble humeral umbone is another smaller impression ; discal punc- 

 tures coarse, somewhat irregularly and rather closely placed, largely 

 obscured by coating; vestiture not forming stripes and not mottled. 

 Ventral surface nearly fiat, with much longer hairy pubescence; 

 sculpture of large, shallow, rounded punctures, distantly placed. 

 Legs large, with similar coating to body. 



Female. — Rostrum about the same length as the prothorax, sub- 

 equally arcuate. Antennae inserted slightly beyond the middle. 



Male. — Rostrum a little shorter than the prothorax, thicker, about 

 three times as long as wide. Antennae inserted nearly three-fifths 

 from the base. 



Length, 9.5-11 mm. ; width, 2.8-3.6 mm. 

 Type locality. — Phoenix, Ariz. (D. K. Duncan) . 

 Other localities. — Roosevelt Lake, Rice, Florence, and Bill Wil- 

 liams Fork, Ariz. ; Las Cruces, N. Mex. 



ry^<?.— Female, Cat. No. 29025, U.S.N.M. Type, allotype, and 

 eighth paratypes in National Museum. Paratj^pes in the collections 

 of the Canadian National Museum, Philadelphia Academy, Kansas 

 University, Colorado Agricultural College, Illinois State Natural 

 History Survey, and in the private collections of F. S. Carr, D. K. 

 Duncan, C. A. Frost, Warren Knaus, H. P. Loding, and J. B. Wallis. 

 Somewhat closely related to ferforatus LeConte but considera- 

 bly larger and more robust, and nearly completely covered with a thick 

 pollinose coating. The rostrum is proportionately longer and more 

 distinctly depressed. There is no visible lateral elytral stripe as in 

 fresh specimens of that species. The punctures on the head are 

 smaller, not so closely set, therefore do not generally tend to coalesce 

 and form grooves, and the punctures on the upper half of the ros- 

 trum are also smaller. The punctures on the pronotal disk and on 

 the elytra are smaller and shallower. On the pronotum of ferves- 

 titus the intervals might be described as alutaceous. In both species 

 the pronotum may be either moderately sulcate as in the type or 

 impressed by a narrow line. 



LIXUS FLEXIPENNIS, new species 



Elongate subcyiindrical, somewhat strongly depressed, a little less 

 than four times as long as wide. Black, strongly shining; vestiture 

 fine gray, not forming lateral stripes; rostrum, disk of prothorax, 

 and anterior half of elytra at middle highly polished glabrous or
