binotatus Lee. 



Elytra without well-defined dark maculation 5 



3 — Ground scales of the elytra more or less pale brown or ochreous in color. 

 Scales of the pronotum more elongate and more distinctly subradial in ar- 

 rangement from a point on the median line behind the middle ; white pat- 

 tern of the elytra very obscure cockerelli n. sp. 



Scales of the pronotum shorter and more broadly rounded. 



White scales of the elytra chiefly conspicuous in a broad sutural vitta ex- 

 tending from the apex nearly to the base suturali§ n. sp. 



"White scales of the elytra forming a more distinct pattern, consisting of 

 two uneven posteriorly arcuate transverse series, the sutural vitta always 



very short adspersus Lee. 



Ground scales of the elytra dark brown in color, with an obscure pattern of 

 pale dots forming the usual two transversely arcuate series. California. 



koelielei n. sp. 

 6 — Inner marginal lines of the eyes very feebly diverging toward their su- 

 perior limit ; size large, the darker scales of the elytra smaller in size. 



missourianus n. sp. 

 Inner marginal lines strongly diverging upward ; scales of the elytra virtually 

 uniform in size. 



Size large, 3 mm. or more in length operculatus Say 



Size moderate or small, much under 3 mm. in length. 



Scales of the elytra almost uniformly white, the condensed spots rather 

 obscurely defined. 



Pronotum coarsely punctate ; form noticeably stout sparsilS n. sp. 



Pronotum much less coarsely and more densely punctured ; form less 



stout than in nanidus ; size very small floridanilS n. sp. 



Scales of the ground of the elytra dark brown, the pale condensed spots 

 much more distinct ; the usual short sutural vitta joining the two trans- 

 verse series especially developed nauultis Lee. 



'?' — Posterior offset of the sutural white spot transverse ; pronotal scales rather 



small toward the middle ; striae coarse quercus Say 



Posterior offset posteriorly and outwardly oblique. 

 Median scales of the pronotum large and rounded ; strise coarse. 



frontalis n. sp. 

 Median scales of the pronotum very small, narrow and linear ; strise quite 

 fine, the subapical umbones much more pronounced.... cavifroiis n. sp. 

 8 — Elytral scales pale, with an oblique lunule on each from the humeri to be- 

 hind the middle, there curving forward and meeting on the suture at the 



middle, of dark brown. California lunatus Lee. 



Elytral scales dark, with obscure and ill-defined pale markings. 

 Eyes most approximate at the middle of the interocular surface. California. 

 Larger species, more than 3 mm. in length. 



Upper internal margins of the eyes more strongly divergent, the front 

 at their superior limit about twice the minimum width wide.
