In all my fxptTiincnts, I have used as parriits only normal rolort-d individuals, 

 and bred tlif dcsftiidants the second lime in a normal temperature, with the results 

 noted above. 



As I di-sired to make otiier expirirncnls. by lireidiii^r J uniiniti ehrysaliiN 

 in dry air, but eould not obtain any new ones from outside, I used thi-se just 

 described butterHies, and picked out again all normal colori'd males. However, 

 I had to use some females with appendices, as I had only one normal colori'd. 

 The chrysalides of this third generation. I put in the mirror case with much 

 light, yo degrees warm, but this time dry air, as I hail believed dry air would 

 produi-e small eye spots. Nevertheless, I got seven feniales, six of which had 

 appendices; and sixteen males, three with ap|)endices. In the fourth generation 

 lired in dry air, I got sixty femah'S, forty with appendices, five of these with 

 double eye spots; and (ifty-nine males, three with appendices. Most of these 

 butferriies were somewhat lighter in color than our lix-al form. I bred another 

 generation with the same result. Then I raised six caterpillars on a pot plant 

 in the mirror case, as dry as possible, got the chrysalis there, and bred them 

 there in <)" degrees. The result was striking, all the eye s])ots being reducicl in 

 size. I hope to repeat this experiment Jigain later on. 



I am also developing some most interesting results in breeding out continuous 

 generations in cool air, and these will be recounted later. 



It is now of exceeding importance that other species of the genus be bred 

 under similar widely varying conditions in order that we may possibly come to 

 understand the origin of some of the striking variations that may appear in these 

 bred specimens, and jierhaps work out the relationships and phylogeny of all the 

 species more fully. Dr. Dyar expresses the opinion to me that Junonia vellida 

 of Australia is the most primitive type in the genus. I am exceedingly anxious 

 to obtain eggs or chrysalids of that species, or any others of the geiuis and shall 

 be glad to correspond with lepidoptcrists in any part of the world relative to 

 the matter.
