 INTRODUCTION^". 



As is 〜、- eil known, Darwin (り payed a special attention to the vari- 

 ability of the eye-like spots upon the surface of the wings of birds and 

 butterflies. In " Descent of Man", he entered into this subject very 

 attentively, devoting two complete paragraphs. Thence the- same 

 problem has often become the subject of investigation of several students 

 of variation, whose attention was specially directed to the markings of 

 insects, a mono- whom Bateso n/^^ Mayer,(io) Bachmetjew," Giard,**) 

 and Kellogg and Beul/?) are to be mentioned. As to the ethological 

 significance of such spots, an ingeneous hypothesis has been proposed 

 by PouLTON. ひ ト"） However, to get clearer insight of this problem, ma【）y 

 laborious works will still be needed. Some of them might be expt'ri- 

 niental, but such statistical method as that employed in the present 

 report is by no means unnecessary, still more so in getting some precise 

 datH from the state of nature.
