come in direct descent from Lucia and appear later. Mr. Lintner's 

 observations lead to the same conclusion, though confined almost 

 wholly to Ncglccta. He has found this form between May 12 

 and middle of June, in successive years. On June 9 observed 

 four pairs in copulation. Hij only Violacea recorded appeared 

 May 12 and 19, and same year Neglecta was flying from May 16 

 on, so that the two forms were contemporary in part of their 

 periods. As above stated, Mr. Saunders shows two broods of 

 Neglecta, the later one flying in July and August. I have taken 

 Neglecta, at Hunter in the Catskills, September 8. There was 

 no general flight, but here and there a butterfly. It is much to be 

 hoped that further observations may be made by some of our 

 northern lepidopterists on these forms. 



As stated, I have received from Montana males of J^iolacea 

 and Marginata, and both sexes of Neglecta ; from northern 

 Colorado, Lucia and Neglecta ; from southern Colorado, \Holacea 

 and its black male, and both sexes oi Neglecta ; from Nevada 

 Psendargioliis, from Arizona a form slightly differing from Violacea, 

 which I have called Cinerea ; from southern CaHfornia, Neglecta 

 $) $ ;from Mt. Hood, Oregon, a female very near Neglecta. 



[But nearly all the Pacific examples, and many from Arizona, 

 are what Dr. Boisduval names Piasus. They expand from i inch 

 to 1.3; in color, the males are violet-blue, the under side not 

 quite white, but color oi Neglecta of the Atlantic slope, and the 

 markings are as in that form, pale but distinct. But the females 

 are not often like those oi Neglecta. The blue of the disk is duller 

 than in the males, and there is no white as in the two forms 

 named ; the black border is confined to the hind margin, as in 

 many Lucia and Violacea. The costal margin is blue in many 

 examples ; others have a fuscous wash over costal margin, and 

 both these winter variations are found in the eastern winter forms, 

 but not in Neglecta. The under side is usually more like Neglecta 

 than Violacea. But with 1299 sent me by Mr. W. G. Wright, 

 came i ? closely approaching Neglecta, in the black borders to 

 both margins, and to Violacea in the indistinct markings of under 

 side. The upper side is deep blue, with no trace of white on 

 disk, and therein also it differs from Neglecta. The female before 

 spoken of, from Mt. Hood, is much the same as this from south 

 California. Piasus evidently stands between Violacea and 

 Neglecta. Some males in the shade of blue cannot be separated 

 from Neglecta, nor can they in the appearance of the under surface, 

 and therefore I have tabulated this form as found in California^ 

 Piasus first appears at San Francisco, according to Mr. Henry 

 Edwards, " about the end of March or the beginning of April, as 

 soon as the peach and cherry trees are in blossom." It is his 

 opinion that in that locality there is but one annual brood of the 

 larva. He says that there is absolutely no green vegetation in 

 the lowlands of California after July, and there would be nothing
