epigynum and the peculiar palpus of the male are constant in essential 

 features and at once reveal the species beneath more superficial differ- 

 ences. The pattern of the markings on the legs, the cephalothorax 

 and of the dorsum of abdomen remain pretty nearly the same alwa3's 

 except as to depth and distinctness of the colors. The venter of the 

 abdomen becomes dark or even black with age, the entire animal also 

 then taking on a darker color.
