 25-29 (days) = of 16 pupse : five ab. 

 mesoides, four were var. teloides, and seven intermediate forms. Two 

 specimens show traces of a " nota." The ground colour was almost 

 normal, slightly browner. The seven intermediate specimens would 

 be like the parent form if the ground colour were more brown. The 

 size of the specimens was normal, mostly somewhat larger than 

 that of the parent ? , seldom smaller. There were no large 

 forms, neither in pt. 1, nor in pt. 2, but in Brood I, of which 

 the ? was a larger one, many very large specimens made their 

 appearance from the -f° pupte, both from -\-° and — ° larvae. 

 The results from part 2 of brood IV, compared with those from part 1, 

 point out, I think, that the retardation of the oval development 

 strengthened hereditism, as shown by a somewhat less characteristic 

 reaction to low temperature (which was not below the shade or night 

 temperature of the season), while the browning, darkening effects of 

 heat, as compared with the results from other broods, were much 

 heightened — evidently by the influence of the parent ? , ab. brunnea. 

 This wild ? , ab. brunnea, need not, however — as shown by the ab. 

 mesoides-brunnea from — "pupae and larvse of brood II — itself have been 

 developed in the pupal stage by heat, the brown colour, especially of a 

 lighter shade, being producible by opposite (retarding) influences, acting 

 already in the larval stages. 



These records seem, so far, to show that the influence of the 

 parent female, as regards distinctive facial detail, makes itself felt in a 

 very decided way, when ova, larvae, and pup^e are bred m the mean 

 shade tetnperature. The parent males were unknown to me, but if 

 they were nearer ab. teloides (all those T saw flying about, and could 

 examine in the spring were so, and on the 3rd May, I captured a very worn 

 (? , ab. teloides-nif/rifasciata, trans.), then their influence would have 

 come out in the ^-"iarvfB and +°pup?e, very strikingly. 



As regards the influence of the oval and larval stages in broods I 

 and II, the records show that heat ova and beat larva?, produce ab. 

 teloides, and will still produce ab. teloides (as oval and larval form), but 

 of a lighter ground colour, even if the pupje are, after pupation, 

 immediately transferred to the mean shade temperature, in which
