Art. 18 NEW NORTH AMEEICAN WEEVILS CHITTENDEN 11 



flattened on the anterior face, punctulate at apex, punctation much 

 obscured by vestiture. First funicular joint wide, little longer than 

 wide, second distinctly longer but not longer than third and fourth 

 together. Pronotum as wide as long, moderately depressed, sides 

 for two-thirds their length parallel, anterior third narrowed to apex. 

 Antescutellar impression about one-fourth the length of the prono- 

 tum, narrow, of moderate depth; surface coarsely irregularly and 

 deepl}?-, variolately punctate, vestiture at middle fine and hair-like« 

 Elytra more than twice as long as wide, slightly wider at base than 

 pronotum ; humeral umbone not prominent ; postscutellar impression 

 shallow, nearly flat, wider than long; sides from humeri two-thirds 

 toward apex nearly parallel, apices nearly closed ; vestiture fine, dull 

 gray, third and fifth intervals each with a vitta of long gray squam- 

 ules with lateral transverse branches, the effect being strongly vit- 

 tate; strial punctures of moderate size, deep, comparatively sparsely 

 placed, the spaces between variable but averaging less than the 

 diameter of one puncture. Legs rather slender, except anterior 

 femora which are strongly clavate. 



Length, 5.5-8.4 mm. ; width, 1.4-2.2 mm. 



Type locality. — Baton Rouge, La., August IT, 1909. Reared from 

 stem of Iva ciliata (Hunter No. 219). 



Other locality. — Torras, La. 



r?/^e.— Male, Cat. No. 29033, U.S.N.M. Type and three para- 

 types. 



Female. — Rostrum a little shorter than the pronotum and about 

 one-fourth longer but scarcely more slender than male. 



The species is fairly distinctive by the unusual arrangement of 

 the elytral vestiture, causing a beautifully striped effect. It is 

 apparently most closely related to scrohicollis Boheman. The small- 

 est measurement applies to a specimen that is immature and obvi- 

 ously depauperated, from Torras, La. It has been reared also from 

 stem of A'lnbrosia species. 



LIXUS DISSIMILIS, new species 



Elongate oval, less than three times as long as wide; subcylin- 

 drical, black, joints of antennae dark rufous. Vestiture dense gray 

 with broad vitta on flanks of prothorax and with or without a 

 broad sublateral vitta on each elytron. Head with large irregu- 

 larly-shaped shallow fovea, punctures coarse in undulating rows. 

 Rostrum in the male short, about three times as loiij^: as wide, thick, 

 distinctly arcuate, slightly bent backward below middle, coarsely 

 punctate in undulating rows to apical third where punctation is 

 finer. Prothorax and elytra very similar to scrohicollis Boheman 

 but the strial punctures are larger and more closely set and the 

 basal ones are either quadrate or nearly so.
