approaching the cage, always from the lea side, however, and usually 

 flutter madly about the cage. A particularly fine and desirable varia- 

 tion, however, appears to be aware of his value to the entomologist 

 and gives the place a wide berth. Over fifty perfect and a large 

 number of imperfect males were captured by means of imprisoned fe- 

 males. Among them were several very black specimens and a few 

 beautiful denudata. The males cease flying at about 3.30 P. M., when 

 they alight in the brush, and a trip up the mountain slope in the late 

 afternoon often repays one for his efforts. The females are sluggish, 

 easily captured, but more rarely seen. In Shasta the insects hibernate 

 as pupae, but in the vicinity of San Francisco as ova.

 mature larva (July 17, 1907) is 1.05 inch long, head light brown, body 

 pale yellow, clothed with paler, clay-yellow hairs, longest at the caudal

 1908.
