LÉPIDOPTÉROLOGIE COMPAREE 437 



Gynandromorphic spécimen. 



This spécimen is figured on PI. A, Fig. 7. 



The wings and antennge are of the normal maie form, but the 

 abdomen is female. However, in drying, the left side has col- 

 lapsed very greatly, whiist the right remains as it was originally. 

 Possibly this indicates a slight mix-up of the génital organs. 

 The thorax, too, shows a mixture of the sexes, for the right side 

 has the patagia black, outlined in white, as in the maie, whiist 

 the left side, which is smaller, is marked like that of the female. 

 It will be noted that this reverses the tendency of the abdomen. 



Variation of the imagines, etc. 



There is but little to add to what has been said in discussing 

 the imago. The gênerai trend is in the same direction as in 

 helenœ, but there is greater variation in the direction of the lines, 

 which tend in some cases to follow the curves of those of pomo- 

 naria. There is a marked inclination of the su ff usions on the 

 hindwings to disapjjear; however this is never accompanied by 

 any weakness of those on the forewings. 



Nor is it necessary to say anythmg further about the habits 

 of the two insects, for they are absolutely alike in the two forms. 

 The ova also are quite the same. 



Hybrids between " Ithysia zonaria " and " Pœcilopsis lapponaria. " 



(A) Ithysia zonaria cf x Pœcilopsis lapponaria Q = hybr. merana. 

 Ithysia hybr. merana (Burrows, Ent., Ital. XVIII, p. 132). 



As I hâve, unfortunately, never had the two hybrids between 

 zonaria and lapponaria together in their early stages, I hâve 

 delayed making detailed descriptions of the form I reared, until 

 I do breed the two. For what few particulars I can give of the 

 larvae of merana I am indebted to Mr. Mera.
