14 PROCEEDINGS OF THE NATIONAL MUSEUM Vol 77 



ered with short vestiture, rather closely and irregularly punctate 

 forming rows at sides, finer toward apex. Scrobes extending fully 

 four-fifths from the base. First funicular joint a little shorter and 

 wider than second, second subequal to third and fourth combined, 

 third and following joints not very distinctly separated, club long. 

 Prothorax nearly as long as wide, tubulate anteriorly, sides poste- 

 riorly subparallel; disk with shallow median impression; surface 

 rather finely and densely, not variolately punctate, interspaces dis- 

 tinctly punctulate. Elytra distinctly wider at base than prothorax, 

 anterior angles acute ; base of outer two striae flat at sides forming 

 a slight depression, which borders a slight tumidity at the sixth 

 and seventh intervals ; surface feebly rugose, strial punctures rather 

 coarse, in regular rows; vestiture not mottled. First and second 

 ventral segments nearly flat at the middle. Legs slender; anterior 

 tibiae finely serrulate on the inner edge. 



Length, 7-8 mm. ; width, 1.9-2.2 mm. 



Type locality. — Iowa City, Iowa, October 7, 1916 (R. Whittle). 



Other locality. — New Orleans, La. (H. Soltau). 



r^/^e.— Male, Cat. No. 29028, U.S.N.M. Two males, type and a 

 paratype. 



Moderately distinctive, differing from Pncristatus., new species, by 

 the much shorter and slenderer rostrum, which with the head is more 

 coarsel}^ and densely punctate. The ante-scutellar impression is 

 negligible. The female is unknown. 



LIXUS PERVESTITUS. new species 



Moderately elongate subcylindrical, three times as long as wide; 

 opaque black, surface except rostrum, and antennae with fine, short, 

 cinereous pubescence, over which is a longer yellow pollen-like coat- 

 ing, much obscuring the punctation. Rostrum shining black, ap- 

 proximately as long as the prothorax, slender, somewhat feebly sub- 

 equally arcuate, slightly bent downward in front of scrobes, with or 

 without a fine carina from head to interantennal fovea; interocular 

 fovea wanting; head with comparatively very large subvariolate 

 punctures, similiarly punctulate on intervals between as on prothorax, 

 punctures continuing on rostrum in the basal half much finer, dis- 

 tantly irregularly placed ; on the apical two-fifths, finely punctulate. 

 Antennal scape dark red, remainder covered with gray pubescence, 

 first and second funicular joints subequal in length, latter shorter 

 than third and fourth together. Prothorax a little longer than wide, 

 subcorneal, widely and moderately deeply impressed in the basal half, 

 or more or less throughout its length, feebly arcuate at sides ; surface 

 of disk very coarsely variolately and sparsely punctate, intervals be- 

 tween punctures minutely punctulate, the yellow vestiture at sides 

 diverging from the apex toward the base, becoming felted at the sides.
