LEPIDOPTERA IN JERSEY. 127 



specimens figured and described by Barrett were taken. The 

 one or two records which I have seen of the captures of yellow 

 and white specimens seem to indicate that these varieties also 

 are found only in the vicinity of the coast. The yellow speci- 

 mens seem to be similar to the form described by Seebold under 

 the name var. mincki (Berliner Entom. Zeitschrift, xxxvi. 1891, 

 p. 467). The yellowish white form, suhalhida, Verity {ante, p. 56), 

 appears to be intermediate between var. mincki and my white 

 specimens. I therefore propose the name alhida for the white 

 form (figs., 1, ?; 3, 3^). 



On looking at this series one can hardly help speculating as 

 to the possible cause of the albinism. The question is essentially 

 one for experiment, and the observations which appear to give a 

 clue to the answer are those of Standfuss, who showed that the 

 majority of aberrations were caused by the effect of abnormal 

 temperature conditions on the pupa. He showed, moreover, 

 that the general effect of treating the pupa as in his "heat " ex- 

 periments was to produce aberrations in which the colours were 

 paler than the normal. Numbers of aberrations similar to those 

 actually occurring in nature were produced in this way, but I 

 am not aware that tithonus was one of the species treated.
