Argynnis alcestis n. aberr. suffusa (Plate IV, fig. 5). 



The whole surface of the fore wings is suffused with black, except for 

 a narrow strip along each margin. Two fulvous spots remain in the 

 discal cell and faint indications of the fulvous spots just within the 

 submarginal line, which is very broad. On the hind wings the submar- 

 ginal line is also very broad and a black suffusion covers the greater 

 part of the discal cell. In the usual form there is an area beyond 

 each of the median row of black lunules which is of a slightly paler 

 tint than the rest of the wing but in this specimen these areas are 

 largely suffused by black, causing this row of narrow lunules to be re- 

 placed by a band of conspicu6us black spots. Beneath, the black 

 suffusion on the fore wings ceases abruptly along a line extending from 

 a point two-thirds of the way out from the body on the inner margin 

 to one three-fourths of the way out on the costal margin and parallel 

 to the outer margin. The apical silvered spots are almost obliterated. 

 On the under side of the hind wings the silvered spots of the sub- 

 marginal row are to a considerable extent suffused with black ; the 

 silvered spots of the median row are largely black ; and much black 

 appears about and between the silvered spots on the basal portion of 

 the wing, these spots themselves being slightly larger than in the ordi- 

 nary form. The black, silver, and cinnamon brown of this surface of 

 the hind wings produces a lively contrast which is quite pleasing. 



This form is described from one male specimen collected in 

 a bog south of Grand Rapids, Michigan, in August, 1897. It 

 has the appearance of showing the effect of cold, but if that 

 factor was the only one involved in its production it seems 

 strange that such an aberration is so rarely met with among 

 the species of this genus. 



The second form is one of Chlorippe celtis Bd.-Lec. 



Chlorippe celtis n. aberr. inornata (Plate IV, fig. 6). 



In this form the ground color of all the wings above is of a browner 

 tone than the average specimen. The median band of white spots on 

 the fore wing is gone and the olive-brown ground color extends out 

 over the discal portion of the wing, leaving only an apical black patch 

 with four white spots, and a black border along the outer margin. No 

 trace of submarginal pale lunules is present and the eye spot between 

 the first and second median ncrvules is represented by <mly a small 

 dot. On the upper surface of the hind wing all markings are obliter- 

 ated except a faint trace cf the two eye spots next the anal angle and 

 the faint markings in the discal cell. An irregular submarginal black- 

 ish band extends across the wing and is broadest toward the costal 

 margin. On the under surface, the wings show the same tendency to
