primaries. Beneath : Basal two-thirds of primaries darker than outer 

 third, black lines in cell very faint ; inner edge of hoary margin cleaner 

 and in sharper contrast with the brown. Secondaries very much as in 

 type o 3 white margin of basal area wanting, except for a dash near the 

 costa ; hoariness between arcuate series of spots and basal area extending 

 from inner margin to the free nervule ; basal area somewhat lighter near 

 costa, and with a vague sprinkling of whitish scales. The browns of both 

 wings brighter than in $ . Expanse, 31 mm. 



Type ;5 taken at Lakewood, N. J., on April 27, igo6; type ? 

 taken at Lakewood, N. J., April 21, 1907. 



These types were selected from a series of 84 (all from the same 



locality) with a view to avoiding extremes of coloration. Of the lot, 45 



have been selected as paratypes, 32 males and 13 females. The following 



variations are found among them : The two fine, brown marginal lines 

 are (rarely) merged into a single broad one (both sexes) ; the white line 

 within these is (frequently) reduced, though never wholly absent ; some 

 specimens have a bronze or olivaceous reflection in certain lights; the 

 rufous suffusion is often quite absent, and, on the other hand, is sometimes 

 conspicuous, in one exceptionally brilliant 9 (paratype No. 25) it extends 

 to the i^rimaries ; basal area of secondaries sprinkled with yellow scales 

 (paratype No. 15); variegation of this area (always slight) sometimes a 

 little less, sometimes a little more, obscure than in types ; extramesial 

 stripe of primaries beneath variable in intensity, and in extension from 

 costa (in paratype Nd. 25 it extends to the submedian vein) ; relative 

 values of the browns beneath somewhat variable ; submarginal spots on 

 primaries occasionally rather faint, especially among the males, but always 

 present ; spots of the arcuate series on secondaries sometimes obscured 

 or absent between the subcostal nervules. 



During the winter of 1904-5 Mr. Wm. T. Davis presented the junior 

 author with two males (April 30) and one female (April 26) of this species, 

 taken at Lakehurst, N. J. The value of the form was not recognized by 

 us until after two seasons of collecting, the constancy of the characteristic 

 markings, coupled with the fact that each year these butter/lies appeared 

 with atigustus, and from a week to ten days earlier than either irus or 

 Henrici (both of which are found, though not commonly, at Lakewood), 

 convinced us that it was entitled to specific distinction.
