usually silghtly tinged with cream, and has the 
dorsal surface rough and uneven, usually depressed 
around the dorsal nucleus, on the sides near the 
stigmal areas and at the two extremities. However 
there are individuals in which the surface about

is very visible and pure white in color. The wax 
is hard, homogeneous, not distinctly divided into

rigid in the older specimens, and is reddish brown 
in color, With the caudal horn black, short and thick, 
directed directly backwards, and is about 0.775
