402 LÉPIDOPTÉROLOGIE COMPARÉE 



left one is female for one fifth of its length, and is then, except 

 for the irregularity of the pectinations, almost maie. The right 

 one is almost the same, save that the " femaleness " extends 

 a little fnrther but there are isolated pectinations. Up to two 

 thirds of its length it is then just as in the maie of pilzïi, but the 

 remaining one third, except for one or two pectinations, is almost 

 female. 



Beneath, were it not for the size of the body and the detached 

 portions of maie genitalia, the insect is just like an ordinary 

 pïlzïi Q. 



This spécimen is figured PI. A, No. i and its genitalia on 

 PI. L, No. i<o. 



2. This is a smaller spécimen. 



In gênerai appearance, this spécimen is much like the first on 

 the left side, except that the subterminal pale band is broader, 

 whiter and less distinctly toothed. The scaling also, is stronger. 

 There is a perceptible greyness, suggestive of the pale ground 

 of pomonaria, in both wings. The wings are fully fringed, and 

 bear, especially on the hmdwings, the spotting of poinonaria. 

 The right forewing is much the same, but the corresponding 

 hindwing is total ly différent, being, except for the fringing, the 

 same as in pilzïi Q . This is brought about by a change in the 

 vems, which weaken after the cell. 



The body of this spécimen is gynandromorphic and in a very 

 curious fashion. The right side of the thorax is female, resem- 

 bling that of pilzii Q, but the left is of the ordinary maie type 

 of pilsii. The abdomen is nearly female and has however, a 

 degenerate ovipositor protruding; the right side; shows distinct 

 maie tendencies The fur on the abdomen is of the nature of 

 that of a female, but the colour is nearer that of langei Q. 



The right antenna is maie and is just as in pUziiçS^ but the 

 left antenna, except for a few pectinations one third from the 

 tip and a few elsewhere, is Q . 



This is figured on PL A, No. 2.
