8 PEOCEEDINGS OF THE NATIONAL MUSEUM Vol 77 



subparallel, narrowed but not tubulate anteriorly ; flattened on disk, 

 surface sparsely variolatelj'^ punctate, punctures of nearly same size 

 except at apex, where they are very small and rather widely sep- 

 arated ; interspaces very finely densely punctulate ; feebly impressed 

 in antescutellar region, where the vestiture is longer. Elytra less 

 than three times as wide as long, scarcely wider at base than pro- 

 notum, humeri not prominent, umbone not visible, sides parallel 

 from humeri nearly three-fourths to apex, apices nearly closed at the 

 ends ; postscutellar impression very short, wider than long, moderate 

 in depth, not extending at the sides beyond the second intervals; 

 humeral impression obsolete, strial punctures small, rounded, moder- 

 ately separated in very regular rows, both transversely as well as 

 longitudinally, the transverse rows imparting a subrugose aspect 

 to the exterior; disk vestiture mottled. Ventral segments finely 

 sparsely punctate, with fine gray hair-like vestiture. Legs slender. 



Length, 6 mm. ; width, 1.8 mm. 



Tyye locality. — Opelousas, La. (G. K. Pilate). 



Type. — Female, Cat. No. 29031, U.S.N.M. A single specimen. 



A distinctive species of the sylvius group, easily recognized by the 

 remarkable regularity of the strial rows of elytral punctures. It is, 

 moreover, the smallest and slenderest of this group. Other dis- 

 tinguishing characters are the short and narrow postscutellar 

 impression, obsolete humeral impression and unusual rostrum. 



LIXUS QUADRATIPUNCTATUS, new species 



Elongate subcylindrical, a little more than three times as long as 

 wide, sides parallel, convex, pronotum distinctly flat, plumbeous, 

 antennae red, vestiture gray, moderately coarse on the head, sides and 

 middle of prothorax and sides of elytra with long hairs coated with 

 yellow ; elytra with last four intervals covered with a gray vitta that 

 more or less conceals the punctation. Head finely punctate on ver- 

 tex, coarsely, somewhat sparsely punctate between the eyes; fovea 

 small. Rostrum not quite so long as the pronotum, very feebly 

 arcuate, coarsely sparsely punctate at base, feebly punctulate at apex. 

 First funicular joint subequal to second, second shorter than third 

 plus fourth. Pronotum subquadrate, tubulate at apex ; feebly irreg- 

 ularly depressed at middle, depression wider at base; surface irreg- 

 ularly subvariolately punctate. Elytra distinctly although only 

 slightly wider at base than pronotum, humeri not prominent, umbone 

 obsolete, sides parallel in basal three-fourths, widest a little posterior 

 to the middle, narrowing in apical fourth, apices nearly closed, post- 

 scutellar impression short, humeral impression wide and deep ; strial 

 punctures coarse, dense; vestiture short and fine. Ventral surface 

 with dense very long gray hair. Femora slender. 



Length, 5.8 mm. ; width, 1.8 mm.
