cj ? . lircast oil ciu'li siilc witli a rccldisli tawny liori/diitai stripes, not (uiiiid in 

 any other species ; abdomen ludow (•innainon-rutbus, witli creamy mesial sjiots, 

 largest on proximal segments ; legs the same colour as ahdomen. A small vitreons 

 space in apex of cell of forewing, not divided. Vitreous area of liiiidwing below 

 followed behind by a creamy patch. 



c?. Tenth t(!rgite sliaped as m fuci for nils, but sinuate beneath before apex, not 

 at tip ; sternite of the same tyjjc as in .stand nujeri, but narrower. Left clas)K'r 

 (PI. IjI. f. \H, I) deeply sinuate ventrally, the proximal ])art not so much 

 jirojecting as in fiiciformiK, also broader than in tln/ahc, the apical lobe less slender 

 than in t/ii/shi^, harpe not projecting, gradually narrowed, with a few hairs ; right 

 dasper (/•) broader than in tlii/abe, feebly emarginate ventrally beyond middle, harjie 

 (//) without free process, gradually narrowed to a point. Penis-funnel (p-f) 

 carinate beneath, ending in a slender and smooth point ; peuis-sheath differing from 

 that of all the other species in the apical process being truncate and, at the apical 

 edge, dentate (PI. LI. f. 18, P). 



Early stages not known. 



llab. Atlantic district : Canada ; New England ; rare, and therefore probably 

 overlooked in the more southern States.

cj ? . Vitreous area of cell of forewing not divided by a scaled fold. Body 

 more shaggy than in gracilin and fhi/.^he, but less than in titi/u.'t. Legs more or less 

 extended black ; long spurs comparatively shorter than in tifi/n.^. Very variable 

 individually, seasonably, and geographically. 



S. Tenth segment essentially as in tlu/sbe, sternite always asymmetrical, often 

 emarginate at the right sight, the vestige of the right lobe of veitata then being a 

 little more distinct than usually. Claspers (PI. LI. f 21) not very unlike, often 

 nearly the same, the right one generally slenderer ; left harpe ending in a short 

 ])rocess, bearing some hairs ; proximally of the process there is a curved, somewhat 

 halfmoon-shaped hump densely beset with minute spines ; right harpe similar, but 

 tlie process longer, often clubbed, with long hairs at the end. Penis-funnel (i'-f) 

 truncate, smooth ; process of penis-sheath >imple, pointed. 



Larva similar to that of tJujshi' ; dorsally shaded with brown, mesial line 

 accompanied at each side by a darker (not paler) line. — Food-plants : Symphori- 

 carpus, Lonicera, Apoctpium, etc. 



Hab. Nearctic Region from the Atlantic to the Pacific. 



The various forms of this insect have been described as 1 3 distinct species. Since 

 Hulst proved by breeding that the forms of thi/sbe with dentate and non-dentate 

 wing-borders were the same species, the belief in the distinctness of the allies of . 

 dijfiniii has become shaky. Smyth, in 1900, succeeded in rearing several broods 

 of diffinis, and found that the diflerences assumed to be specific by the older writers 

 are in fact only seasonal or individual. On comparison of the individuals of our 

 long series from various parts of the Nearctic Kegion we find that there is no 

 structural difference between all these "species" in question, but that there are 

 well-marked geographical races each variable in itself. These races are : (1) the
