460 LÉPIDOPTÉROLOGIE COMPARÉE 



abdominal and on the thoracic segments. The contrast between 

 the ground colour and the filling in of the stripes is very great. 

 The subdorsal stripe, which is fuUy twice as broad as m hunii, 

 generally lacks the lower edging, and may even be connected with 

 the supraspiracLilar stripe, which is very feebly indicated, except 

 on the first fi.ve abdominal segments. The " yellow " bars are 

 greatly influenced by pomonarïa and are nearly cream coloured, 

 with a yellow ring around the primary tubercle within. Thèse 

 bars, as in pomonarïa, may appear on the sixth and seventh abdo- 

 minal segments. 



The collar is exactly the same in the two hybrids and so are 

 the two warts on segment eight, the two yellow spots before the 

 anal plate, and the plate itself. 



The spiracular stripe is much reduced compared with hiiniï, 

 but is just as strong on the thorax. In fact, on the abdominal 

 segments it is only bright and clear before the bright yellow 

 spots and under the spiracles. Thèse spots, too, are reduced in 

 size and are like those on pomonarïa. The spiracles are black. 

 Beneath, the larva is light grey and the stripes are as in pomo- 

 narïa, but the fiUing in is slightly pinkish. The legs and prolegs 

 présent no différences. 



The larva on the whole, is much more variegated than hunii, 

 owing to the greater contrasts in the colours. There is no doubt, 

 however, but that the larva, in spite of the fact that it is three 

 quarters pomonarïa in blood, if found wild, would be called 

 kïrtarïa. 



As one would expect, ail the tendency in variation is toward 

 pomonarïa, and to the development of its strong suffusions, 

 although one larva had a distinct purplr ground colour as dark 

 as that of hirtaria. 



Pupas. 



The pupae, in appearance, much resemble those of Juinïï but 

 they vary enormously in size. Three were as small as those of
