localities. The species is especially characteristic of the dense thickets 

 of tall ragweeds. Ambrosia trifida, which ahound in all moist areas and 

 are especially frequent about the boggy spots at the foot of the bluffs along 

 the outer edge of the stream bottoms. The earliest nymph stages appear to
