No. 396. ] THE COLORADO POTATO BEETLE. 929 
crop of potatoes of this vicinity is annually saved from the 
D. 10-lineata by the predaceous habits of the C. bipunctatus, 
the presence of which, doubtless, is worth many hundreds of 
dollars to the potato growers of San Juan County, New Mexico, 
and maybe to those of elsewhere as well.
