THE CANADIAN ENTOMOLOGIST. 71 



imposed, pure white spots, united, except where cut by median 

 vein, and linear, longer then with near ally. Reniform is of ground 

 colour, inwardly marked at top and bottom by a white dot, never 

 wholly white. Secondaries pale, luteous yellow with rows or 

 purplish reflection that deepens in a marginal band. Beneath 

 powdery, shaded with purplish. Size is very constant with no 

 disparity in the sexes. Expanse, 27.5 to 31 mm. The male 

 genitalia conform to the usual type pattern of the yellow species, 

 the irregular, spinulated cucullus, the long curved harpe, dorsally 

 edged in part with fine teeth, indicate the common generic features 

 here. Habitat: Southern Canada and eastern United States 

 generally through range of foodplant. Montreal and north shore 

 of Lake Erie, Can.; Webster, N.H.; Buffalo, Albany, Staten Island, 

 Rye, West Chester Co., N.Y.; Fairfield Co., Conn.; Newfoundland, 

 N.J.; New Brighton, Pa.; Wilmington, Del. Type locality: To 

 meet the desired exactitude, the locality of the particular male 

 type example thus labelled is Polly Park Wood, N. 42 deg. W. 

 530 meters intersection of Purchase St. and Polly Park Road, 

 Town of Harrison, West Chester Co., N.Y., U.S.A. 



Twenty specimens showing equally the sexes are at hand. 

 Paratypes will be placed in the U. S. National and British Museums; 

 the male type with the author. 



The larval period extends from the first week of June to Aug. 

 15, the larva hatching from the hibernated egg. As an instance 

 of disparity, early pur pun 'fascia moths begin to emerge by this 

 last date. By the second larval stage the continuous dorsal stripe 

 is conspicuous, that alone being unbroken. The colour is a warm 

 shade of brown seemingly deeper on the middle by reason of the 

 absence of side lines. In these early features it is similar to a 

 dozen other species. 



Stage IV. — Characteristics normal; head golden yellow, side 

 marking not always present; body cylindrical, colour sienna brown, 

 lines cream white, dorsal alone entire, a wide well-defined stripe; 

 tubercles brown, IV the largest, about three times the size of 

 spiracle, on joint ten III and Ilia tend to coalesce, IV large and 

 low down, IVa above the line of spiracle and smaller. 



Stage V. — Similar, the proportions cylindrical and attenuated. 

 Penultimate stage. — Little change, the ground colour lighter
