that only those having portions of their anatomy of the S ^hape 

 should be called gynandromorphic. 



Mr. C. P. Pickett exhibited a drawer of representative specimens 

 of Ani/erona prunaria showing results after interbreeding for 19 

 years, the last five years being devoted to colour. Those fed under 

 yellow surroundings are all of a decided orange-yellow, many females 

 approaching the males in coloration ; those fed under green, the 

 ground coloration being much paler, approaching more to whitish- 

 yellow, quite a contrast to the orange-yellow forms. Those reared 

 under red conditions are of a deep rich orange in the males and 

 deep banded chocolate in the females, the chocolate predominating, 

 the yellow in some cases being almost absent. Those reared under 

 pink are certainly lighter in colour, the chocolate markings being 

 broken up, and the yellow extending through to the edge of the 

 wedge. The ex'hibit included a long series of ab. pickettaria. This 

 form shows the chocolate bands very narrow and running across 

 nearer the centre of the wings, the borders being quite yellow in the 

 females and orange in the males. 



Mr, Pickett also exhibited several drawers of A;iriades corUlon 

 aberrations taken in the Herts district in 1916. 



Males. — Uppersides : — Long series varying in colour from 

 whitish-blue to almost cuUmu blue, containing ab. fouieri ; many 

 without the black borders ; several ab. mart/inata with the black 

 margin extending along the lower wings, giving them a striking 

 appearance ; one with lower wings of a lilac shade ; several ab. 

 siiJf'Ksa and ab. iniiior : one with left side wings typical, right side 

 upper wing ab. nitff'Ksa, and lower wing powdered black over the 

 whole area ; another with left side lower w^ing of a bleached whitish 

 shade, the other wnigs being normal ; one with right upper wing 

 rounded same as lower wing with cilia extending around ; one with 

 only three normal wings, the left upper wing missing entirely (was 

 captured flying). 



Undersides: — Two perfect ab. ohsuleta; three with -extra large 

 spotting ; one with left side lower wing true ab. absoleta, and the 

 other wings typical ; one of a white ground colour with hardly any 

 trace of markings on border, the black dottings showing very con- 

 spicuously ; three with very dark ground coloration approaching the 

 female. 



Females. — Uppersides : — Long series containing ab. se>iii-.v/n- 

 grapha : five almost ab. si/)iiiiapha\: four with the whole of the wings 

 black, showing no border markings; five with the upper wings
