Specimens of typical pusilla were collected on rushes (Hatch), on 
Carex stricta (Knab) and on flowers of spiked maple (Frost). 
var. PYRITOSA Leconte. 
This western form differs from typical pusilla in having the antennal 
joints more elongate, especially the outer, the form generally more slender 
and the coloration very variable, being bronze, cupreous, metallic green, 
blue, purple or black. The antennae are occasionally almost entirely 
black. The coloration of the legs, size and form of prothorax are the 
same as in typical pusilla.

The antennal joints of the females of this form are generally of the 
same size as those of the males of the typical eastern form. However, 
the antennae are variable, eastern specimens occur occasionally with 
more elongate antennal joints and western specimens with rather short 
joints. 
It is of interest to note that the western specimens are much more 
variable in color than the eastern specimens. I have seen at least 70 
or more of eastern specimens nearly all of different shades of bronze or 
copper, a few had a slight bluish tint on disk of elytra and only two 
specimens were obscure-green, 
var. ROBUSTA Schaeffer. 
This form is generally more robust and larger, the prothorax is 
relatively wider below the lateral tubercles and more feebly converging 
behind than in typical pusilla, the serial punctures of elytra are usually 
coarser and the legs are always unicolorous reddish. The color is bronze
