Callidryas euliile, Linn. The two forms are abundantly- 

 distinct, more especially in the male sex. 



Dry form. $ Under side. Hind-wing, and all exposed 

 part of fore-wing, irrorated with red-brown ; the markings 

 strong; stigmata clearly outlined. 



$ Under side. As in male but reddish irroration darker. 



Wet form. $ Under side. No irroration : brown mark- 

 ings very faint ; stigmata faintly outlined. 



$ Under side. Reddish irroration very faint. 



Intermediate specimens are frequent, approaching now 

 one, now the other form. 



It may be at once admitted that these two forms of C. 

 eubule are not restricted to the respective seasons to any- 

 thing like the extent that is observed in the case, e.g., of 

 the S. African Precis octavia, Cram., and its "dry" form 

 P. sesamus, Trim. Thus on 12 Jan., 1907, C. eubule was 

 seen in numbers flying about a weedy field at Temple 

 Hall, on the road between Constant Spring and Castleton, 

 Jamaica. Three examples were secured ; a female of well- 

 marked "dry" and one of equally well-marked "wet" 

 type, whereas the third, a male, may be described as 

 " intermediate, inclining to wet." I was informed that 

 there had been no rain for three weeks.
