the spots as conspicuous on l)oth \vin_i4s as in many P/ii/odiir. '["here 

 is always a little pink at base of hind wini^ in l)oth sexes. The discal 

 spot of under hind wing is usually white, but occasionally is diluted 

 rose. Now it is the fact that the males bear a certain resemblance to 

 the males of C. Ju f trior. Dr. Hay en, in his Colias paper, Proc. Host. 

 Soc. N. H. xxii, p. 165, claims that in Wash. Terr., he took ^ $ $ 

 5 9 9 of Harfordii and Barbara, and that Mr. H. Edwards "recog- 

 nized instantly" that they were of that species. It is true, ei.u:ht of 

 these nine examples had wing's of a peculiar shape, "only one has the 

 wings of the common shape," and no males have submarginal spots 

 below. Nevertheless, "they cannot be separated from Edwardsii, ex- 

 cept as a somewhat extravagant variety connected to the type by inter- 

 mediate forms." On p. 167, we read, Harfoi^dii And "' Laurcntina seem 

 by the shape and color of the upper side to be nearly related to Philo- 

 dice, but otherwise to belong to Edwardsii = C. Interior. Till the 

 contrary is proved they should be so placed." The probabilities are 

 that not one of the 83 ^ (? 46 9 9 captured by Dr. Hagen in Wash. 

 Terr, and treated of in the paper quoted, was Ed-ccardsii. Such 

 wild comparisons as the above are so frequently made in this j^aper 

 that I must infer that true Edicardsii is yet unknown to Dr. Hagen. 

 ' ' Till the contrary is proved they should be placed with Edzvardsii 

 = Inferior.''' I do not undertake to pronounce on these nine S 9 sup- 

 posed Harfordii, except to say that they could not possibly be Har- 

 fordii if they were Edzvardsii, and they could not possibly be Edzvardsii 

 if thev were Inferior. Nothing is more certain than that, but what 

 they were I have no idea. They had "a peculiar shape," unlike that 

 of Har-fordii, and while they are not described, it is let out that there 

 was no trace of submarginal spots, which is a feature of Harfordii. 

 Edzvardsii is a large species, has a black discal spot without yellow 

 centre, yellow fringes, and the under side is dusted over the margins 

 of primaries and all of secondaries with gray scales like Alexandra; 

 the discal spot of hind wings is small, white, with a delicate edging of 

 rosy scales. There is no trace in either sex of submarginal spots. 

 That is a very different thing from Harfordii, of either type, and no 

 lepidopterist would have thought of comparing the two. 



As to Inferior, the differences are decisive, and indicate a different 

 sub-group. The description of Barbara ( 9 ) given by Mr. Edwards 

 settles the matter in a few words: "border broadest at the apex, thence 

 narrows slightly, and continues of equal width to the inner angles." 

 There never was seen an Edzvardsii or an Interior with a border like 

 that. Mr. Edwards, as if he had a prevision of the memorable raid 

 into Wash. Terr, to be made one summer day by our great Neurop- 

 terist, adds: "in this respect it differs greatly from Eaure^itina, in 

 wiiich the band is apical only, and obsolete before reaching the inner 

 margin.'' Lanrerifina is Inferior, neither more nor less, and that is
