 brown and dark scales, those on head cupreous; thorax with a bifurcated 

 lateral stripe and a median dorsal line paler. Thorax with sides almost 

 parallel for two-thirds their length, thence more rounded to apex; discal 

 punctures equal, dense, deep. Elytra one-fourth wider than thorax, strong- 

 ly emarginate at base, humeri short, oblique, or feebly rounded; striae 

 strongly punctured; intervals wide, flat, each with a row of minute yellow- 

 ish inclined setae. Length 7.8 9.5 mm.

205 (8451). LISTROXOTUS FRONTALIS Lee., 1876, 133. 



Oblong-oval. Blackish; elytra thickly clothed with small, rounded, 

 dirty brown scales, those of head and thorax more or less cupreous; an- 

 tennas and tarsi reddish-brown. Beak slender, subcylindrical, scarcely 

 longer than thorax, with three fine carinse, the grooves on sides almost 

 obsolete. Thorax as long, female, or slightly longer, male, than wide, 

 sides broadly rounded, disc finely and densely puncate. Elytra one-third 

 wider than thorax, feebly emarginate at base, humeri rounded, sides slightly 

 converging for three-fourths their length, then gradually narrowing to 

 the conjointly rounded tips; striae coarsely punctured, intervals flat, rather 

 wide, each with a row of short setae. Last ventral of female with three shal-

Lake, Steuben and Vigo counties, Ind. ; June 10 July 27. Fre- 

 quent along the beach of Lake Michigan and the borders of ponds 

 and ditches. Sarasota, Fla., Feb. 25. Ranges from New England 

 to Michigan and Iowa, south to Texas. The thorax is usually 

 impressed near apex and in fresh specimens has a narrow 

 median line and wider sinuous lateral stripes of silvery gray- 

 scales, the latter extending back on the humeri. The narrower 

 body, subtruncate base of elytra and more prominent setae, espe- 

 cially on the declivity, make it readily known.
