AET. 18 NEW NORTH AMERICAN WEEVILS — CHITTENDEN 9 



Type locality, — Colorado Springs, Colo., 6,000-7,000 feet, June 15- 

 30, 1896 (H. F. Wickham). 



Type. — Cat. No. 29024, U.S.N.M. Sex indeterminate. Unique. 



The species is moderately distinctive by reason of the peculiar 

 coarse punctation of the rostrum, the irregularly variolate-punctate 

 pronotum, and the dull gray or plumbeous color. It belongs in the 

 Sylvius group. 



LIXUS SYLVIUS PROFUNDUS, new variety 



Elongate cylindrical, nearly four times as long as wide, polished 

 black, mostly glabrous with very sparse vestiture. Head with round 

 interocular fovea, 'surface at base distinctly, very irregularly punc- 

 tate and finely densely punctulate. Kostrum in the female longer 

 than pronotum (as viewed from the side), more slender than in nor- 

 mal Sylvius Boheman but not .so slender as in acirostris, new species, 

 very feebly arcuate. Pronotal impression distinct, extending from 

 base nearly to apex, punctures very irregular. Elytra with promi- 

 nent umbone, striae strongly deeply punctate. Vestiture sparse on 

 ventral surface. 



Male. — Rostrum a little shorter than pronotum, much more robust 

 than in female, a little less than three times as long as wide, coarsely 

 punctate in basal portion to interantennal fovea, from that point 

 punctulate to apex. Entire surface still more coarsely punctate than 

 in female. First ventural segment faintly and narrowly impressed 

 at middle. 



Length, 6,75-10 mm. ; width, 2-3 mm. 



Type locality. — St. Louife, Mo. 



Other localities. — ^Washington, D, C, (F. H. Chittenden) ; Arling- 

 ton, Va. (F. H. Chittenden); Georgia; Mobile, Ala, (H. P, Lod- 

 ing) ; Nashville, Tenn. ; Texas; Lexington, Tex, (Birkman) ; San

Type. — Female, in the Canadian National Collection, Ottawa, 

 Canada. Allotype and nine paratypes, Cat. No, 29029, U.S.N.M, 

 Paratypes in collections of Illinois Natural History Survey and of 

 C, A, Frost, 



It is evident that the specimens studied, 12 in number, are abraded 

 and there is evidence that the lateral vittae of the elytra may be dis- 

 tinct in some specimens and wanting in others, as in normal sylvius 

 Boheman. 



LIXUS CKASSIPUNCTATUS, new species 



Elongate cylindrical, about four times as long as wide, moderately 

 depressed, black, feebly shining, vestiture consisting of long gray 

 hair-like scales forming a very broad lateral vitta from eyes to apex 

 of elytra, somewhat concealing punctation of nearly half the elytral
