the three shields forming a triangle. Median dorsal scales very

circle of scales bordering the anal, none of which are much enlarged. 
Young greyish-brown above, with longitudinal series of white, 
black-edged ocelli ; no light vertebral streak ; lower surfaces whitish, 
immaculate. Adult female brown or greyish above, the vertebral 
zone darker than the sides of the back, with large dark brown 
spots with a central white shaft or round spot; usually the larger
