310 THE ENTOMOLOGIST. 



preparations, I found a perfectly formed larva in the female 

 body. I at once announced the fact to him that P. apollo 

 brought forth its young alive ; but after discussing the matter, 

 we both came to the conclusion that the fertilized ovum had just 

 missed being laid before the mother had been killed, and the 

 egg had subsequently hatched. This larva was exhibited at a 

 meeting of the City of London Entomological Society, without 

 any doubt being expressed against its being the larva of the 

 species under examination. 



The other day I mounted a pair of Colias edusa, when I again 

 observed a fully developed larva in the oviductus communis 

 curled round, the head and tail touching, thus forming a ring. 

 I communicated this to Mr. Burrows, and on my arrival at his 

 house a few days ago, we examined the remaining three speci- 

 mens of female P. apollo, one of which contained a fully deve- 

 loped larva, the other two, only eggs. Mr. Burrows then turned 

 to a pamphlet sent him by Mr. L. B. Prout, a reprint of Mr. 

 N. J. Kusnezou's article in Russian on " The probable Viviparity 

 in some Danaid, i. e. Pierid, Butterflies," in which he tabulates 

 his similar experiences, and mentions several species of the 

 genus Colias and others having the gift of viviparity. As he 

 does not mention Paniassius apollo, I think it is as well to put 

 on record the fact that this species also belongs to this viviparous 

 group.
