A two-winged fly {Lydella doryphorce Riley, Fig. 102) is also parasitic in the grubs. There are also several species of the Ti- ger beetles and Ground-beetles, that occasional- ly attack the grubs, and de- vour more or less during the season. Anoth- er enemy which promises to be a very efficient aid in keeping this pest in check, is the Potato-beetle mite (Uropoda aniericana Riley, Fig. loi). It is a very minute and interesting species of mite belonging to the Acarina, and was first discovered in Ohio, and sent to Prof. Riley in 1873. The past season (1879) I found this para- site quite abundant in New Jersey, and it was apparently doing good work in de-.
