Though most of the specimens before us are immaculate in 
coloration, some show traces of dark markings. In these, a few 
of the proximal antennal joints are darkened, while the cephalic 
and median tibiae show faint annulation and the dorsal surface of 
the caudal femora weak dorsal tessellation proximad. In addition, a 
few specimens have the lateral lobes of the pronotum somewhat 
darkened. ~ 
Few of the specimens at hand have retained any traces of the 
pink tinge, said to be shown by living specimens. Strange to say, 
three or four specimens that have the head, pronotum, and limbs 
showing a distinct pink tinge appear to have been killed before 
they had become thoroughly hardened after reaching maturity, 
though as a rule such material discolors badly in drying.
