same region. The two agreed in having the upper surface of a very 

 peculiar hue, all pale ochre, with an orange tint on disks of secondaries. 

 Under side yellow, densely dusted black over whole surface of second- 

 aries; the discal spot, as in Alexandra^ white without ring. Till this 

 season I have seen no other example, so far as I remember, but in July 

 received several males from Mt. Judith, Monta., agreeing with the type, 

 except that being fresh the color was light ochraceous. By the immac- 

 ulate under side and peculiar dorsal spot, the species is n&2iX Alexandra. 



And here, behold, a wonder comes to light! Our Doctor says, p. 

 158: "I have submitted to Mr. H. Edwards a $, Edwai-dsii, from W.T., 

 with similar color (to Astrcea, and he decided that // was much like 

 AstrcEa. Mow this color was prepared pii-rposely. When the specimen 

 was taken // was put in a freshlyprepared cyanide bottle, &c., &c., by 

 which the yellow color was altered to color of Astrcea & ." 



On another occasion " I had sent Mr. W. H. Edwards a few Colias 

 from the same expedition." These my ingenious friend had treated with 

 benzine, and he naively proceeds: '■'■that benzine changes yellow I have 

 learned only later through experijnents made for that purpose.'''' " J made 

 excuses for sending the specimens in bad condition, and was answered 

 that these Colias 7vere especially interesting to himP 



What an escape! Surely some good angel saved me from the snai-es 

 of this chemical fowler! When beguiled with cyanide I said it was 

 very near; when tempted with benzine the other said it was very in- 

 teresting! An enterprising laboratory that of the Cambridge Mu- 

 seum ! 



C. Scudderii is compared with Occidentalis before it is dropped into 

 the capacious maw of the Interior, along with so many other good 

 species. Scudderii really stands next to Felidne, and is entirely dis- 

 tinct from Occidentalis, and it is not worth while to spend more words 

 on it. 



Colias Emilia is put down as identical with Ediciardsii ^.n6. Alexandra. 

 I might say, which? I have never seen but the pair belonging to Dr. 

 Behr, which I described in 1870, and since that date have not seen 

 these. Dr. Behr was satisfied that they were a distinct species, and he 

 is a good judge. Dr. Hagen quotes Mr. Henry Edwards as saying 

 that the <^ (which appears all that is left of the pair), " may be a form 

 of Inte?'ior.'" It can't be Edwardsii, Alexandra and Interior all to- 

 gether, for they are three species, belonging to two sub-groups. 



C. Harfordii. While my perplexed friend has been losing himself in 

 the dust of his own raising, I have spent my summer in trying to learn 

 something of several species of Colias by breeding them from the ^'gg. 

 In other words, while the Doctor has been working at the wrong end, 

 I have done my work at the right end. Three species have I bred in 

 part, and two from &g% to imago, and ohe of these two is Harfordii, 

 W. G. Wright of San Bernardino sent me abundance of eggs and 

 young larvae; the former obtained by tying females in bags over their 

 foodplant. Astragalus, The female of this species is Barbara, 

 H.E., but there are ^ $ of Sho.. Harfordii ty^^, ?,vA $ $ of the .^^^zr- 

 bara type. I have examples which agree precisely with the descriptions, 

 and there are variations from that. Barbara is described as bright can-
