The Grape-Berry Moth. 123 



Descriptive Notes on Some New Species of American Moths that have 

 BEEN Confused with the Grape-Berry Moth. 



BY W. D. KEARFOTT 



The following notes are from breeding records extending over the past four 

 years, which have convinced me that each of the species described, as well as a 

 nmnber of others waiting for better material, completes its entire yearly cycle 

 of two or three broods on a single food-plant, and also with little doubt each 

 food-plant supports a separate and distinct species. This does not seem unrea- 

 sonable, for in Europe there are twenty described species in the genus Poly- 

 chrosis. 

 Synopsis of species. — 



1 . With large outer marginal patch of front wing indented above anal angle 

 by a spur of ground color 2 



With this patch evenly roimded on outer edge, not indented below 



botrana 



2. With inner half of front wing imiformly Ulaceous or leaden-blue, crossed 

 by well-defined narrow brown lines 3 



With inner half much mottled with reddish brown or gray 4 



3. With ground color of outer half of front wing rich ochreous-brown 



liriodendrana 



With ground color of outer half of front wing pale yellowish-brown . wfeano 



4. With dark color of central fascia of front wing extending to dorsal 



or inner margin rhoifructana 



With this dark color concentrated about and above middle of wing, and not 

 reaching dorsal or inner margin slingerlandana 



It is not imlikely that the European botrana is or may become established in 

 America, although of all the specimens examined I have not seen a single one 

 that could be referred to it, hence it is included in the synopsis and a brief de- 

 scription added. On the other hand it would not be surprising if the American 

 viteana should at some time be introduced into Europe. 



Polychrosis botrana Schiffermiiller.— Front wing: ground color ashy-gray, with 

 a pale ohve-green lunate spot or patch on outer end of wing; the inside edge of 

 this spot nearly straight, and outer edge evenly rounded and its lower half de- 

 fined by ciha. Just beyond middle of wing is an irregular fascia, shaped much 

 Uke outhne map of South America, pale olive-green on inner and lower area, 

 and replaced by velvety black on outer and upper area. A narrow fascia of 

 olive-green crosses wing half way between central fascia and base, and between 

 the narrow fascia and base are two abbreviated narrow fascia arising from dorsal 

 margin and terminating at middle of \\ang; these bands are more or less overlaid 

 with black scales. Five large, well-rounded, costal spots on outer half of wing, 

 the outer one in the apex, and inner in central fascia; and there are several smaller, 

 black, costal dots on inner half of the costa. The costa is very narrowly edged 

 with white. Hind wing: very pale gray, a shade darker at apex. Expanse 12 

 to 13 mm. 



Polychrosis viteana Clemens. Front wing: ground color, Ulaceous 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 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 turn- 

 ing upwards towards costa, and almost joining submarginal patch. The inner 

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