distinct. In all of the latter species the beak is short and 

 equalled by the antennae, while in the new species the antennas 

 are somewhat shorter. The present species is less robust, has 

 smaller and finer punctuation, and less evident setae. The 

 anterior coxae are separated by one-half of their own width, 

 and the sternal groove is broad and shallow. 



The type and the paratypes were collected by the writer, 

 feeding on the terminal buds of Xanthium commune at Dallas, 

 Texas, August 15, 1906. Subsequently the same" species was 

 bred from the roots of this plant, larvae being found August 

 2Qth and pupae October 2nd. 



Type and paratypes deposited in U. S. National Museum, 

 No. 10038 ; remaining paratype in collection of Cotton Boll 

 Weevil Investigation. 



Baris nionardae n. sp. 



This species runs in Major Casey's table for the species of 

 Baris to dichotomy 23, and belongs next to inconspicua, from 

 which it differs by having the beak in the female as long as 

 the prothorax, and in the male four-fifths as long. Oblong- 

 oval, not robust, the upper surface rather feebly convex, black 

 and polished throughout. 



Head very minutely, obsoletely punctured, the beak deep and closely 

 so, strongly arcuate ; antennae as long as the beak in the male, and four- 

 fifths as long in the female, the club large, abrupt, with basal joint polished. 



Prothorax about two-fifths wider than long ; sides convergent, though 

 less so than in deformis to apical one-fifth, then strongly convergent and 

 feebly sinuate to the apex, which is slightly sinuate ; base about two and 

 one times as wide as the head, straight from the broad, rounded median 

 lobe ; disk coarsely deeply and densely punctate, without impunctate 

 line, the punctures not one-half as wide as the scutellum and separated 

 by very narrow margins. Scutellum subglabrate, impressed. 



Elytra one-half longer than wide, twice as long as the prothorax, and 

 at the small and moderately prominent humeri slightly wider than the 

 latter; sides convergent, nearly straight in basal one-half; apex broadly 

 rounded ; disk with moderately wide, deep, abrupt, finely punctured, 

 crenulate grooves, the intervals flat, narrow, not more than once and a 

 half as wide as the grooves, each with a single series of feeble punctures 

 which are over one-third as wide as the intervals, and not separated by 

 more than their diameters ; setae very small, silvery. 



Thorax beneath coarsely, very closely and deeply rugulosely punctate.
