These two are easily known l)y the large size and red elytra, 

 sulcate in gigas, not in cmarginata.

Varies in the extent of the black markings, and LeConte's name 

 vitiosa is applied by some to the specimens with elytral tip black, 

 reserving obliterata for the lighter specimens withont black tip.

Very close to the preceding, but the elytra lack the ante-medial 

 spot and the antennce are stouter, the fourth joint more distinctly 

 shorter than the fifth than in obliterata.

These seem to be rare in collections, and I have been unable to 

 procure specimens of deleta and plebeja. The descriptions in table 

 will serve to identify them. The general form is similar to the 

 neighboring species.

An abundant and variable species, S and 9 differing in color, 

 the 9 being much the blacker. The normal marking of thorax is 

 black with yellow sides 9 . yellow preponderating S , or reducing 

 the black color to a discal line in the form elegans Lee. The elytra 

 are normally black with a yellew vitta interrupted at middle and not 

 reaching tip 9 , or yellow color exceeding black S , or reducing the 

 black to a short, transverse, medial spot, form elegans Lee. The 

 black color also disappears almost entirely from the legs in this 

 extreme form.
