0)1 the iienus Colias. 9 



If Meadii is a good species, it is probably more limited 

 in its range than any other Colias known to me, except 

 perhaps C. imperialis, being confined, as far as we know, 

 to the mountains of Colorado, at and above 10,000 feet 

 elevation, where it appears to be common. In this 

 species the black discal spot of fore wing is reduced to 

 a minimum, and in some cases appears only as a faint 

 streak ; this was considered by Zeller the only specific 

 character in which it differed from Myrmidone.

 I need have added nothing to what I said of this 

 species in my first paper had not the subject been con- 

 fused by the addition of fresh synonyms by Mr. Butler, 

 who seems quite unable to pass by any specimen difier- 

 ing in the slightest from those in the British Museum 

 collection without describing it as new. 



I can say with tolerable certainty that his C. minuscida 

 is nothing whatever but a smaller form, probably the 

 spring brood or first generation of Vautieri. There is 

 nothing whatever in the figure, description, type-speci- 

 mens, or in the one wiiich I possess labelled C. minuscida 

 by Mr. Edmonds himself, which would give the least 

 reason to doubt this ; and Mr. Edmonds' statement 

 that minuscida occurs in August and September, and 

 the larger form, Vautieri, in October, would have been, 

 I imagine, enough to convince any other lepidopterist of 

 the necessity of at least advancing some evidence that 

 it was a distinct species. Mr. Butler, however, settles 

 the matter to his own satisfaction by a most concise 

 footnote, " Undoubtedly another species."
