DESCRIPTIONS OF THE LARVA OF MELANITIS 

 LEDA, AND OF THE LARVA AND THE PUPA 

 OF PAMPHILA MOHOPAANL 



By Herbert A. Green, F.E.S. 



Melanitis led a. 



Larva. Ground colour yellow, a median dorsal green stripe and 

 some narrower ones on each side from head to tail. The surface of 

 the body is roughened. The head is the only variable feature in the 

 numerous specimens I have had. In some cases this is entirely 

 black except for two small white spots, one on either side of the 

 head at the lower angle close to the mandibles ; in others there 

 is only a narrow black line from the base of the horns, or pro- 

 jections, down the side of the head to lower angle. In all cases 

 there is a narrow white line immediately behind and touching black 

 on the head. Horns black in front, reddish-brown behind, and 

 covered with bristles. Caudal processes not as long as cephalic 

 horns, very slightly divergent. Several have been " ichneumoned " 

 by a common dipterous Hy. 



Pamphila mohopaa^ii. 



Larva. Pale green with two white lines, divided by an equal 

 width of ground colour, dorsally narrowing gradually at head and 

 tail until they disappear. Head black, with four whitish marks, 

 two small at lower angle of head, two larger extending from crown 

 to half way down head ; these two spots are divided by a thin pro- 

 jection of the black. Length about two inches. 



Pupa. The pupa is pale greenish white, the head prolonged to a 

 point about an eighth of an inch in length. On the under side is a fine 

 projection starting from the middle and extending nearly to tail. 

 One curious feature about this pupa is that the white efflorescence 

 is deposited on the leaf before pupation and not, as in heitliloa, 

 appearing after pupation on the pupa itself. Feeds on Bush Guinea 

 Grass. 



Durban (Natal). 



NOTES AND OBSERVATIONS. 



Ephemera producing Living Young. — It seems by the following 

 extracts from well-known books that information with regard to the 

 first stages of Ephemera is still wanting. 



Leland O. Howard in 'The Insect Book' says of May-flies, "In 

 one case a female has been seen to deposit living larvae." 



Dr. Sharp in the ' Cambridge Natural History,' vol. v., pages 

 432-3, speaking of the description given by Sir John Lubbock of the 

 metamorphosis of Cloeon, says: "His observations were made on
