Maevia vittata. (529 



Seen from tlie front, are a briglit oi'anp^e color; on tlie inner side, 

 next to tlie niandibles, tliere may be sniall patclies of pigment, as 

 shown in Fig. A8. 



As will be seen by tlie above description, tlie typical tufted 

 male diifers from tlie typical gray male in tlie following cliaraete- 

 ristics; body color, color and pigmentatiun of tlie legs, color of palps 

 and in tlie possession of three tufts of hairs on tlie ceplialothorax. 

 A glance at Fig. AI and A5 will make it clear tliat tlie pattenis 

 on the ceplialothorax and abdomen are essentially similar. In 

 studying the variations foiind in 54 specimens, the above order of 

 discussion will be followed. 



Body Color. 



Tufted Males. The males of this type show a good deal of 

 Variation in the intensity of the body color. The black always 

 predoniinates but in some of the specimens, which have been exa- 

 mined alive, the patteru on the abdomen was almost as conspicuous 

 as in the typical gray male. 



Gray Males. In the gray males there is a tremendous amount 

 of Variation in the general body color. It varies from a very light 

 gray, through a brown to a black, which is almost as inteiise as 

 that of the typical tufted male. In the case of the two ''Inter- 

 mediate males", the abdomens were quite black except for a few 

 lighter spots lying on the edge of the dorsal side. 



Color of Legs. 



Tufted Males. The typical appearance of the leg of the 

 tufted male, is shown in Fig. All. The general color is a light 

 lemon yellow and no pignient is seen except on the coxa and at 

 the tip end of the tarsus, as pointed out above. No variations from 

 this was found in any of the 34 tufted males examined. 



Gray Males. The typical leg of the gray male, in dorsal and 

 ventral view, is shown in Fig. A9 and AlO. The general color 

 is a pale white and on the ventral side, especially of the femur, 

 there are very definite and characteristic bands of pigment. The 

 degree of pigmentation is subject to some Variation in the individual 

 cases but in none of the 40 gray males. examined was the pigment 

 ever absent. The legs of the very dark gray males were heavily 

 pigmented.
