until our mounting frightened them back into the forest. We 

 longed for weeks in this beautiful valley but it could not be. 



Even in the geyser region we found butterflies, and several 

 were captured near the Riverside Geyser while waiting for an 

 eruption. Several Chrysophanus mariposa were taken in the 

 Upper Geyser Basin. Argynnis helena was found flitting along 

 the road alighting in moist places in the neighborhood of the 

 lower falls of the Yellowstone. A single Euptoeeta claudia was 

 taken beside the road. Two Chionobas jutta and a single Melit&a 

 editha were also captured. Thecla scephtm was common near 

 Mammoth Hot Springs. 



Although we ascended no high mountains, Chionobas chryxus 

 was seen several times. Satyrus charon was abundant. Several 

 . Argynnis monticola and a pair of what seems to be the var. pur- 

 purascens, Hy. Edw. fell to our lot. A few Argynnis eurynome 

 were taken. 



In conclusion, the author wishes to record an opinion : — My 

 observations lead me to believe that eurynome, artonis and arge* 

 form a single species, and absolutely intergrade. I have captured 

 about 800 eurynome and have studied specimens from Utah and 

 British America, also some of the intermediate points (Yellow- 

 stone Park and Idaho). Of the unsilvered form called artonis, 

 I have captured over 150 examples. These two forms I have 

 taken in coitu % arionis and 9 eurynome ; and ? artonis and % 

 eurynome. I have seen specimens only partially silvered and 

 resembling both artonis and eurynome. In my collection are 

 specimens of arge % from Oregon which seem to correspond 

 exactly with Mr. Strecker's description of this variety, and I 

 have males from Utah which are certainly arge, and others which 

 intergrade into the typical eurynome. I have never seen a $ 

 which positively belonged to the var. arge, but have noted a de- 

 cided variation in the females of the so-called eurynome. If 

 these so-called species naturally interbreed, and if all the inter- 

 grades have been found as I have proved, it only remains to de- 

 termine positively the result of this interbreeding and the ques- 

 tion is absolutely solved.

 Bridgeport, Conn.
