description of egg, larval stages, etc., see appendix to this 

 article). 



The larvae developed very unevenly in both broods after the 

 second month. In October many had pupated, while others 

 were not half grown, and such as had not then reached the 

 final larval strge were placed in a bed of Cynoglossum in my 

 garden in the hope that they would hibernate there and be 

 found in the spring. A classification of the images of both 

 broods follows. 



PROGENY OF PAIR No. i. 17 259. 

 DIVISION A. 



6 $ 99 . These fifteen examples, a little more than one- 

 third the whole number bred, had deep yellow secondaries, 

 yellow abdomens and yellow suffusion of under surface of all 

 the wings. The proportion of yellow males to whole number 

 of males is about the same as the proportion of yellow females 

 to whole number of females. These yellow r -winged progeny 

 divide into two distinct groups by the difference in the brown 

 markings of primaries. 



Group i 3 $ , 5 9 . One male and one female of this group 

 are represented by Figs. 7 and 8 of plate. These vary but lit- 

 tle among themselves. The tendency toward definition of apical 

 and pre-apical spots is, as shown by the figures, slightly more 

 apparent in the females. 



Group 2 3 $ , 49. These are all alike, and one pair is 

 shown by Figs. 9 and 10 of plate. They are like all the 

 dyiuenc I have seen, though I have some specimens of clymene 

 of unknown parentage in which the secondaries are a little 

 deeper yellow. 



DIVISION B. 



ii $ 1 6 9 . All the moths in this division resemble parents 

 in having white secondaries with a suspicion of yellow tinge. 

 All have white abdomens and under side of all the wings white, 

 or as nearly so as in ordinary examples of confusa and Iccontci. 



These twenty-seven moths show so many variations in pat- 

 tern of primaries that subdivision is not as easy as in the case 

 of the yellow- winged group, but, utilizing the character most 

 widely varying, they may be divided into two groups, viz.:
