scribed. Dr. E. C. Van Dyke very kindly turned over to 
me for study the specimens of this genus in his collection as 
did Dr. F. E. Blaisdell. Among Dr. Van Dyke’s material I 
found one each of the two species taken by myself at Mill 
Valley, and three examples of still another species which 
appears to be undescribed. 
Up to the present there have been described thirteen 
species of the genus Hetaerius in the United States and of 
these seven are from the state of California.* The three in- 
cluded in the present paper make a total of ten for this state 
and sixteen for the United States. Beside these there are 
but five described from the rest of the World.
