maculations of the tegmiua and posterior femora (these parts being 

 uniform in the green phase) being brownish -black. 



Between these two extremes are found many intermediates repre- 

 senting almost imperceptible gradations. Many individuals show 

 variations which are individual or restricted to a comparatively few 

 examples. The most important of these appear to be worthy 

 of note. 



The presence of four converging light lines on the pronotum 

 somewhat in the form of a cross These lines are present only in 

 the brown phase, or closely related intermediates, and in some 

 specimens are strongly marked, but as a rule are but faintly so. In 

 DeGeer's original figure of this species (PI. XLI, fig. 5) this 

 pattern of coloration is repi-esented, though in rather a crude 

 manner. The blending of the chocolate marbling on the lateral 

 portions of the tegmiua to form transverse bars is also a noticeable 

 character. This latter phase is mainly found in the green type.
