MB. W. C. HEWITSON ON DIURNAL LEPIDOPTERA. 143 



Ascaris, the eggs of this parasite perished in less than four months 

 after their immersion in water. During the interval the jar had 

 been upset and most of its contents lost. 



12. ProstJiecosacter injiexus. — The ova of this viviparous species 

 continued to develope their contents after deposition in water, the 

 embryos displaying signs of growth during a period of several 

 weeks subsequent to their escape from the chorional envelope. 



A List of Diurnal Lepidoptera collected by Mr. Wallace in the 

 Eastern Archipelago. By W. C. Hewitson, Esq., F.L.S. 



[Eead Dec. 15, 1864.] 



The very valuable collections of Satyridae, Erycinidse, Lycsenidse, 

 and Hesperidse amassed by the indefatigable industry of Mr. 

 Wallace having been transferred to my keeping, I am happy to 

 comply with his wishes by compiling a list of the species, with 

 notice of all their varieties and localities.
