400 LEPIDOPTEROLOGIE COMPARÉE 



the " lips " of the spiracles are much less parallel edged, for the 

 posterior margin is somewhat convex. 



The bristles on the head of the pupas appear strong, like those 

 in hirtaria^ but those on the body are weaker. 



In gênerai the leg cases, etc., of ail three, are^very similar, but 

 the following minor différences are quite obvious. The antennae 

 cases, while fuller than in hirtaria, bear pectinations slightly 

 weaker than in -pomonaria pupa. The cases of the anterior legs 

 are stouter than in hiriaria, but rarely seem so prominent as those 

 of the other parent. 



The glazed eye of pomonaria projects distirictly but that of 

 hirtaria is very inconspicuous; the hybrid pupa is nearer hirtarïa. 



In the anal area, the génital scars are fine and neat and not 

 rugged like those of hirtaria. In the weakness of the two side 

 spines, the pomonaria influence is dominant. The terminal spines 

 provide us with a very variable feature; we may hâve every tran- 

 sition betvveen the broadbased forked spine of hirtaria and the 

 narrow — stalked fork of pomonaria. The scars of the two warts 

 on the eighth abdominal segment are very distinct. 



II. Female. Whilst most of the détails of the différences are 

 the same as in the maie, there is a great différence in the shape, 

 and in this, pomonaria in followed. The outline of the portion 

 before the free segments, viewed from above, is more parallel 

 edged than in hirtaria. The free segments are not so stout and 

 the taper to the terminal spine is strongly suggestive of pomonaria. 



Naturally, as the female is not fully winged, the wingcases 

 more nearly resemble those of pom.onaria but are just a little 

 broader. 



Viewed laterally, the outline is almost exactly that of a section 

 of a flat dôme, instead of being, as in hirtaria, very full at the 

 meso-thorax. This is due to the fact that, in piLzii and pomo- 

 naria, the meso-thorax is much less broad than long, and the 

 piothorax is more prominent. In hirtaria., the meso-thorax is very 

 broad. The antennal pectinations are scarcely, if at ail, better 

 marked than in hirtaria.
