LÉPIDOPTÉROLOGIE COMPAREE 415 



small as in that species. The longitudinal stripes on the first 

 five abdominal segments arc very faint and, arising from this 

 weakness, the larva, as a whole, resembles pomonarïa. On the other 

 abdominal segments and on the thorax an approach is made 

 to zonaria in a slight development of the longitudinal lines. 



The white collar much resembles that m zonaria, although 

 it is a little more regular and distinct. The black anal plate is 

 outlined in yellow just as in zonaria, and, immediately in front 

 of it, can be seen the two pale spots of hirtaria and pomonaria. 

 The spiracular Ime is well marked but is much more like that of 

 hirtaria than those of either of the parents, owing to the com- 

 pounding of the lack of markings of pomonaria, with the complète 

 spotting of zonaria. The rounded yellow spot on this line is well 

 indicated only on the first hve abdominal segments, although the 

 zonaria spotting is shown. The thoracic part of this line is more 

 like that seen in pomonaria than is the remainder. Ventrally, 

 the larva is blackish throughout, except for the présence of the 

 two central stripes of zonaria. 



Both the legs and prolegs arc blackish and the base of the legs 

 bears a white line just like zonaria. 



2nd INSTAR. 



Length at end : 8 mm. 



Head. The head is black but is freckled, though weakly, 

 with whitish markings. In shape, as in colour, it is very close to 

 zonaria, for the tendency to lobing of the epicrania is but weakly 

 shown. 



Body. The colour is the smoky black of both parents, but 

 the texture of the skin is much coarser than the fine délicate 

 surface of zonaria, although it is not quite so rough in appea- 

 rance as in pomonaria. 



The Eve transverse bands, which are now yellow in colour, are 

 still distinctly marked on the first five abdominal segments, but 

 the yellow spot, which is on the supraspiracular stripe of zonaria,
