CALIFORNIA BtLS OF THL GLNUS NOMADA. 



By Carroll Fowler, Berkeley, €)al^ 



Among the most charaeteristic of our early spring bees are 

 those of the geniLS Xomada, which are to be found i-ather 

 of the University of California. The species exhibit a great 

 deal of variation in color and also in the wing venation. The 

 latter character cannot be used at all in classifying because in 

 abundantly upon our yellow wild flowei"S. This article is based 

 upon a study of the species Xomada in my collection and that 

 the single species bisignuta, of which we have a large series' 

 all th,e extremes of variation in the venation are to be found. 

 The color pattern, although variable, seems to be the most 

 reliable chai^acter. The following synopsis is an attempt at 

 the natural classification of the species known to me, with the 

 probable position of the other California species indicated in 

 foot notes. 



Bright yellow markings on black ground, with very little 

 brown.
