366 LÉPIDOPTÉROLOGIE COMPARÉE 



ditary influence of hirtaria is felt, and the whole larva is purplish 

 or smoke-coloured. The stripes are well developed. The two 

 members of the double medio- dorsal stripe are separated by a 

 wider space than in hirtaria. The edging is black and wavy and, 

 owing to its weakness at certain points, the stripes tend to be 

 confused at the anterior members of the trapezoidal tubercles and 

 to disappear after them. The filling in of the stripes is yellow 

 and hère we hâve a contrast to the sonarïa grey, and hirtaria 

 reddish-orange. 



Ths subdorsal lines are much more parallel edged than in 

 hirtaria, but, nevertheless, as m that species, they are broader at 

 the beginning of a segment. Whilst the edging is less regular 

 than hirtaria edging, it is very much more clearly shown than in 

 zonaria. 



The space in the ground between the subdorsal and subspiracular 

 stripes is more or less closely black-freckled although the rest of 

 the ground contains but few black dots. 



The hirtaria influence, in most cases, where the stripe is not 

 overwhelmed in the black zonaria shading, is dominant in the 

 supraspiracular stripe for it resembles that of that species and the 

 original yellow spot on that line is clearly shown. In spite of the 

 fact that the edging on this stripe is for the most part decidedly 

 better marked than on the others, it is still not so clear and even 

 as on hirtaria. As if to emphasise the influence of hirtaria, the 

 filling in is not so yellow as in the other stripes. 



Taking the stripes as a whole, compared with those of hirtaria, 

 they are more parallel edged and the edging is less continuons 

 whilst they are not so irregular as in zonaria. The space between 

 the stripes averages two and a half times the breadth of a stripe 

 instead of one and a half times as in hirtaria or one and three 

 quarters as in zonaria. As a matter of fact, probably owing to 

 the compromise in shape of the larva, the stripes are narrower than 

 those of either parent. 



Although very veak, the yellow bars are generally indicated in 

 some way and serve to connect the medio-dorsal stripes with the
