1927] Notes on the Mite Pediculoides ventricosus Newport 163 
It is noxious in causing dermatitis in man. The writer has lost 
several hundred hymenopterous parasites of the white pine 
weevil — as have others in rearing various parasites. The sug- 
suggestion is made that the mite is more harmful than realized, 
as the parasites it destroys probably would kill more injurious 
insects than does the mite.
