Apocellus. A. analis and A. gracilicornis are both 

 rather common near water, especially about reservoirs^ 

 irrigating ditches., etc., in cultivated regions: sphceri- 

 collis, one example, Pomona, April. 



Ancyrophorus. A small colony of A. planus was once 

 taken in drift in a mountain canon near Pomona.

 Conte); sonomce, Sonoma County; gracilicornis, Santa 

 Clara to Sonoma counties: validus, Marin County and 

 north.

 water, more especially in the foot-hill and mountain 

 canons: spinicollis, middle and northern parts of the 

 State; found in situations similar to the last.

 optera of Baja California," Supp. I.)-*

Geodromicus.- G. temporalis, quite rare along moun- 

 tain streams, near Pomona, September: kumboldtianus, 

 northern.

 in the middle and northern Sierras.
