Third and 4th antennal segments more slender, about 

 1/6 as thick as long. Corium with a pale spot near 

 outer apex; Marin and Mendocino counties 



franc is c anus (Drake) 19496 



Micracanthia quadrimaculata (Champion) 1900 



This very small, oval species (fig. 7:41) is widely 

 distributed in the western United States and Mexico. 

 M. pusilla Van D. (1941) described from San Diego, is 

 a synonym (see Drake and Hottes, 1950). 



Pentacora signoreti (Guerin) 1856 



Our largest saldid, this species is easily recognized 

 by the five-celled membrane (fig. 7'AOd). It occurs 

 along the southern California coast and Salton Sea. 



Salda buenoi (McDunnough) 1925 

 This is a dull black species with broad but abbre- 



viated hemelytra (fig. 7:40c). It has been taken in 

 Lassen County and Inyo County, California, and 

 occurs northward into Oregon and Canada (see Drake 

 and Hottes, 1950).
