The proportion of the female forms in this very interesting 

 family most nearly approaches thai of Family 4, bred in 1906 

 from a hippocoon parenl (Trans. Ent. Soc, L908, p. 129). The 

 present family contains, however, nearly three times as many

forms. In the numbers of trophonius, l as against 3, and 



of hippocoon, 2 as against 3, there is a close resemblance 



I wo families. 



The 25 male offspring exhibit tin- transition usually

 parent upon the cenea offspring was observed in 1906 (Trans. 

 Ent. Soc. Plate XVII. fig. 8, and Description, p. 313) and 

 of hippocoon upon cenea in 1908 (Trans. Ent. Soc, p. 436).
