CELASTRINA ARGIOLUS. 407 



centre. $ , delicate violet-white (violet at base), with broad marginal band to 

 forewings extending along costa ; strongly spotted margin to hindwings = neglecta, 

 Edw., pi. ii., figs. 11-12. 



10. c? and $ . Exactly parallel pair only larger. Underside white, with 

 contrasting black spots, many, however, obsolete ^pseudargiolus, Edw., pi. ii., 

 figs. 8-9 = neglecta, large form, Scudder. (No doubt a summer form, which may be 

 called neglecta-major, though Edwards insists that it comes from overwintering 

 pupa). 



11. t? . Mauve, with hardly any marginal edge. 2 , ill-scaled and badly 

 pigmented, ground colour and bands washed-out. Underside wbite, varying from 

 well-marked to obsolete in the spotting — neglecta, Edw., pi. ii., figs. 10, 13, 15 <? s, 

 14 ? . (The rapidly-fed-up summer form, pauper, not characteristic neglecta.) 



The above is a summary from our standpoint of Edwards' beautiful 

 plates and his remarks thereon. With some of his conclusions we 

 cannot agree ; his facts, in many cases, too, are wofully insufficient or 

 altogether wanting. He calls pseudargiolus a spring form and 

 neglecta a summer one, but of pseudargiolus, he figures two quite 

 different, but one undoubtedly, and two probably, summer, forms ; 

 indeed, there is no difference whatever in his pseudargiolus, figs. 

 8-9, and neglecta, figs. 11 and 12, except in size, and his data 

 show that he bases his opinion concerning pseudargiolus, figs. 8-9, 

 absolutely on specimens captured on the wing, which he states to be late 

 spring, and which their appearance almost conclusively proves to be early 

 summer, examples of large size. Besides the typical (?) neglecta (as defined 

 by figs. 11 and 12) just noted, Edwards pictures three mauve males 

 (practically without marginal borders), and an illscaled, and illpig- 

 mented female, with very weakly marked marginal band, under the 

 same name. Under the name piasus, Edwards figures (pi. iii) two 

 females of a lilac form, more like a warm-tinted icarus, and very 

 different from the bright, metallic (?), blue female of the preceding 

 plate (pi. ii., fig. 21), which is figured under the same name, bub 

 which, in the letterpress, he refers to as var. echo. Edwards notes 

 (Can. Ent., ix., p. 203) that, in May, 1877, at Coalburgh, he 

 reared a large number of larvae from eggs laid by pseudargiolus, 

 the pupae from which were later exposed in an ice-box, for 

 varying times ; only one, however, emerged in the summer of the 

 same year, a female, which differed from the normal form in having 

 the usual series of extra-discal spots on the underside entirely wanting, 

 w T hilst the marginal crescents, very large and black, form a complete 

 and conspicuous series along the edge of both wings. The other pupae 

 ■went over the winter.
