THE ATTID/E 



55 



variety (fig. 143) is generally smaller and covered with longer 

 hairs and scales. The legs and palpi are more distinctly ringed 

 with brown. The dark spots on the abdomen are larger and 

 more closely connected, so that 

 the markings appear as light 

 spots on a dark ground. 



In alcohol they become bright 

 red and afterward fade to a dull 

 red color that remains for a long 

 time, both varieties in this con- 

 dition looking much alike. 



The males (fig. 142) differ, at 

 first sight, extremely from the 

 females. The legs are ringed as 

 in the female and the brown parts 

 are wider and less obscured by white hairs, 

 while the white parts are whiter. The 

 cephalothorax is dark brown, with a white 

 stripe on each side under the eyes bend- 

 ing toward each other but not connected. 

 The front of the head is also white and 

 covered with long white hairs. The palpi 

 have the femur dark brown at the base 

 and white at the end. The patella and 

 tibia are brown, and the tarsus is brown, 

 with white hairs on the upper side. The 

 abdomen is white in front and 

 around the sides. The middle 

 is dark brown, with a few yellow 

 and greenish scales. The brown 

 area is often notched at the sides in four points and sometimes 

 indistinctly divided into four pairs of spots, as in the female. 

 The male palpi are large for the size of the spicier, and the 

 palpal organ extends back beyond the tibia.
