LÉPIDOPTÉROLOGIE COMPARÉE 41I 



Habits of larvae. 



In most of their habits pihii larvae and those of hunii are like- 

 wise the same, but, generally, those of pilzii feed up at a more 

 rapid rate, in this respect following the other Lycia hybrid — 

 denhami — which also has Jnrtaria as the maie parent. 



Pupae. 



I. Mâle. The pupae of the two are almost identical but the 

 following différences are to be seen. 



The free segments are nearer to hirtaria and the pupas show 

 signs of the influence of that species in being more closely pitted. 



The antennal pectinations are more marked than in filzii and 

 the bulges on the cases of the first pair of legs are not so pro- 

 nounced. 



The mesothorax, too, is not so broad. 



II. Female. The only différence I can see is that the prothorax 

 of pilzii is more prominent, and, as in the maie, the pitting is 

 coarser and tends to be like that in hirtaria. 



Lying over of pupae. 



As in pilzii^ a small percentage, much the same as in English 

 hirtaria, lie over for two winters. In neither hybrid, hâve I ever 

 had any of the vagaries, which observers on the continent hâve 

 experienced, of the Q Q appearing the same year and the maies 

 the following year, or of the pupœ lying over whoIesale, for two, 

 three and even four winters. This, apparently, dépends upon the 

 fact that English hirtaria are less prone to act thus than conti- 

 nental ones are, as I hâve noted myself this year. Certainly, 

 pomonaria cannot affect the matter, for I used German pupae of 

 that species and I perceived no différence in regard to their ten- 

 dency to lie over and that of my Epping hirtaria. 



The imago forms at the same time as, and émerges from the 

 pupa in a similar manner to pilzii.
