THE CANADIAN ENTOMOLOGIST. 137 



THE SYNHALOMA OF CALIFORNIA. 



BY CARROLL FOWLER, BERKELEY, CAL. 



The material for this study was collected by Mr. H. O. Woodworth 

 and myself during the spring and early summer of 1898. At Berkeley 

 the collecting was carried on in a systematic manner, so that the number 

 of each species taken gives a fair representation of their relative 

 abundance. S. albicans and S. Edwardsii are the only species here- 

 tofore recorded from California. The species may be readily recognized 

 by means of the following synopsis : 

 Abdomen with distinct, white bands. 



Small, not more than .25 in. in length albicans. 



At least .40 in. in length. 



Thorax with white pubescence, rather thin on 



disc californica, 9 • 



Thora.x with dense, reddish-brown pubescence .... speciosa, 9 • 

 Abdomen not distinctly banded.

Thorax with dense, brownish pubescence acerba 



Thorax with rather thin white pubescence .albopilosa, (^ 



Pale pubescence extending more or less upon second abdominal segment 



Third joint of the antennje shorter than the first Edwardsii, (t, 



Third joint as long as the first and second combined, .intrudens, ^
