THE ATTID.-E

spots. There is nothing distinctive in the markings of the 

 under side or of the legs except the ornaments of the male. 



The front legs of the male 

 (fig. 125) in this species are 

 much ornamented. The femur 

 has long black hairs on the 

 under side. The patella has 

 long black hairs beneath, a 

 spot of short black hairs on the inner 

 side, and a crest of long white hairs mixed 

 with shorter black on the upper side. 

 The tibia is covered with long black 

 hairs except at the tip, where they are 

 white. There is nothing peculiar about 

 the third leg (fig. 124). The form and 

 general appearance can best be understood 

 from the figures. 



At the mating time the males, as they 

 approach the females, hold the front legs 

 extended sidewise and lifted a little from 

 the ground, with the tibia nearly horizontal 

 and the tarsus turned downward. In this 

 position they advance slowly, at the same 

 time running rapidly sidewise from one 

 side to the other and at short intervals 

 jerking the abdomen and the front legs 

 slightly upward. They go almost close 

 enough to touch the female and then 

 quickly retreat. 



Habrocestum peregrinum. — This is about 

 the same size as aiiratn^n and looks very 

 much like it. The female, at any rate in alcohol, has a more 

 distinct light mark in the middle of the cephalothorax, curving
