be fully oxidized. Sanguineous markings are present in many 

 of the specimens, a pale median vitta on the scutellum is present 

 or absent and the membrane is immaculate or may be distinctly 

 dotted with fuscous. Sometimes the connexivum is completely 

 concealed by the hemelytra and at others left broadly exposed, 

 and it may be uniform in color or may be distinctly maculated. 

 The size of the insect is variable to some extent also. Two 

 extremes in color and size may appear quite different.
