striae; elytra also with a narrower median vitta. Head finely, 

 densely punctate on occiput, fovea shallow, very coarsely and densely 

 punctate between the eyes. Rostrum in the male much shorter than 

 pronotum, very feebly arcuate, distinctly carinate in more than half 

 its length ; surface very coarsely punctate in basal two-thirds, apical 

 third punctulate, an interantennal fovea indicated at end of carina. 

 First funicular joint wide and short, second longer and slenderer, not 

 so long as third and fourth together. Pronotum scarcely longer 

 than wide, basal two-thirds subparallel, apex faintly tubular ; surface 

 irregularly and deeply variolately punctate, punctures small at apex, 

 concealed by vestiture at sides; interspaces punctulate; widely but 

 not deeply impressed in antescutellar region. Elytra narrow, espe- 

 cially at extreme base; humeral umbonal process prominent, shin- 

 ing; basal three-fourths of sides subparallel; apices closed; post- 

 scutellar impression moderate in width and depth; a small rather 

 deep impression above each umbone. Punctation of discal striae very 

 coarse and moderately irregular in closely set rows; punctures very 

 irregular in shape and size, mostly rounded, but some in basal por- 

 tion of disk oval and elongate oval ; the first row most densely punc- 

 tate and the second and third striae containing elongate oval punc- 

 tures. Ventral surface sparselj^ punctate, punctures quite visible 

 because of sparse vestiture, first segment nearly flat, second convex, 

 third, fourth, and fifth widely separated, fifth transversely moder- 

 ately depressed at middle. Legs of moderate length, not very 

 strongly clavate. 



Length, 9 mm. ; width, 2.3 mm. ; rostrum, 1.5 mm. 



Type locality. — Santa Rita Mountains, Ariz., 5,000-8,000 feet, July 

 (F. H. Snow). 



Type. — Male, in University of Kansas Museum, Lawrence, Kans. 

 Unique. 



This species resembles the male of scrohicollis Boheman, from 

 which it may be distinguished readily by the much coarser puncta- 

 tion of the rostrum and elytra. The pronotal punctation is finer and 

 more sparse. The humeral umbone is more prominent, the vittae are 

 broader and different, and the rostrum is distinctly carinate. 



LIXUS IVAE, new species 



Elongate oval, cylindrical, about four times as long as wide, entire- 

 ly black ; vestiture gray, long, fine and hair-like on sides of prothorax 

 and on legs; lateral elytral vittae covering, but not concealing, the 

 punctation of the last five elytral intervals. Head punctulate just 

 in front of occiput, then coarsely densely punctate, punctation 

 extending far between and under the eyes on the rostrum, largely 

 concealed by vestiture. Male rostrum nearly one-fourth shorter 

 than pronotum, less than three times as long as wide, distinctly
