the leaf. Saunders gives a brief account of Polychrosis viteana in his Ontario 

 report in 1882. Felt (1904) reports the first beneficial work from spraying 

 with arsenicals. In some experiments for the control of the Grape Fidia 

 (Fidia viticida) beneficial effects were obtained and the berry worm was 

 partially controlled. Polychrosis viteana was reported as injurious in the 

 vineyards of Ohio in 1868, and again in 1881 it did considerable injury to 

 grapes on the islands of Lake Erie. At various times, its occurrence has 

 been reported from New York, Pennsylvania, Illinois, Ohio, Missouri, Dela- 

 ware, Virginia, North Carolina, Texas, Nebraska and Ontario. 



The adult is a small moth, lilaceous and brown in color, and measures 

 from nine to twelve millimeters across its expanded wings. When at rest 

 the moth is triangular in appearance and is scarcely six millimeters long 

 and not more than two and one-half to three millimeters broad. They take 

 flight at the slightest disturbance and are rapid flyers and crawl rapidly about 

 the breeding jar when disturbed. Keerfoot describes the moth as follows: 

 "Front wing, ground color, lilaceous or leaden blue. The outer marginal patch 

 is sharply indented above the anal angle by a spur of the ground color, the 

 inner edge is less straight than botrana and bulges inward at the middle of 

 wing; the color is dark brown. The central fascia is more slender than 

 botrana, its outer spur is sharply produced, in some specimens turning 

 upward toward costa and almost joining submarginal patch. The inner fascia 

 is narrower than botrana and the two short inner dorsal fascia are only 

 indicated by a few brown scales. Apical spot is larger than botrana and 

 there are three smaller rectangular oblique spots or costa beyond the central 

 fascia. The inner spot, which in botrana is as distinctly defined as the other 

 four, is in viteana not separable from central fascia. A few short streaks 

 on costa before the middle. A shade of pale yellowish-brown involves the 

 outer half of costa between the central fascia and outer patch, giving the
