438 LÉPIDOPTÉROLOGIE COMPARÉE 



The larvse, which he possessed, took readily to hawthorn and 

 birch for food plants, and were much more easily reared than 

 those of either parent which usually die off in captivity when 

 full grown. 



Description of full grown larva, etc. 



The larva, although bearing no very close resemblance to those 

 of either lapponaria or zonaria, and not likely therefore to be 

 mistaken for either, was more of the lapponaria type. The 

 ground colour was purplish like that of the female parent, sho- 

 wing but little traces of the grey ground of zonaria. The longi- 

 tudinal stripes, which m lapponaria are very narrow and 

 degraded and rarely become at ail conspicuous, except when the 

 filling in is clearer as at the transverse yellow bars, are much 

 broader, regular and clearer in zonaria, although the edging is 

 weak or rather dotted. The larva of rnerana foUowed zonaria 

 closely in the stripes. Although they are not so conspicuous on 

 account of the darkened ground colour, lapponaria bears the 

 black suffusions before the yellow spots, and before the yellow 

 bars just as in pomonaria. Thèse suffusions, and also the yellow 

 bars, are produced in the larva cf nierana. The yellow spira- 

 cular strijDe was présent, but it was much less conspicuous than 

 in zonaria, although it was of the usual zonaria type. 



Although the above larvae were so very healthy it must not 

 be supposed that the cross yielded a high percentage of larvae. 

 Two pairings were obtained and both batches of ova were safely 

 deposited; one of thèse failed to yield a single larva and only 

 a portion of the othex hatched. 



Pupae. 



The pupœ, at first sight, are very close indeed to those of 

 lapponaria, and are of the same red brown colour. The wing 

 cases, too, hâve the same red colour and show but little trace of 

 the waxen green of zonaria. The surface is polished a little
