hairs, which gives it a rusty appearance. The tergum is black where 

 denuded of hair. Beneath the abdomen is densely clothed with hair, 

 black in color with the hind margin of the segments dark red. The 

 notch in the last ventral segment is double. There are the same 

 patches of silvery hairs at .the base of the fore wings as in the type. 

 The three females received from Dr. Blaisdell are like the one just

1914. b. var. calif ornica Distant. Ann. Mag. Nat. Hist., ser. 8, xiv, p. 166. 



The type locality for vanduzeei and what are here considered as 

 two varieties of that species, is San Diego Co., California. 



Through the kindness of Prof. Wm. S. Wright I have received 86 

 males and 9 females of vanduzeei; 25 males and 12 females of var. 

 consobrina and 2 males of var. calif ornica collected at Dulzura, San 

 Diego Co., Calif., from June 12 to 25, 1917. Prof. Wright consid- 

 ered that he had collected in this long series but one species, and de- 

 scribes its song as follows: "It is low, long continued and sweet. 

 They will sing for nearly half an hour without a quaver ; they usually 

 are to be found setting high up in the brush, seldom in the trees." 



In addition to the specimens already mentioned the following have 

 been examined, and unless otherwise stated they are in the writer's 

 collection.
