Of tliis species the eollection contains a great number of 

 females. They vary a little in eolour. All of them have 

 the ground-eolour black, but the markings are more or less 

 effaced. Some of the largest specimens have on the dorsal 

 part of abdomen a white ring and before this two Avhite 

 lines nearly foruiing a figare of this appearance ] [. Some 

 young specimens have three ordinary spöts. — I have dra^n

 ]mblished by count Keyserling.

 Orlando.

 a female. It was captured in Orange co. — My figure of
