Life Histurjj of Pseudacraea euryhis hohleyi. 707 



of a leaf of a sapling, remain motionless, hanging from it 

 with wings closed, and then fly away quickly. On looking 

 at the leaf, to my intense pleasure, 1 found an egg on the 

 middle of the under surface, still glistening with the 

 secretion affixing it to the leaf, and of a dull yellow colour. 

 Let me here briefly state the main facts of the life- 

 history. The ixirent was one of the intermediate forms 

 so plentiful in the locality, being an " ohscura " with large 

 pale areas, and a reddish suffusion strongly marked on the 

 under surface of the base of the hindwing, indicating an 

 admixture of the " hohleyi " form. 



The egg was laid on June 16. 



The egg hatched. June 25. 



1st larval ecdysis. July 1. 



2iid do. July 7. 



3rd do. July 14. 



4th do. July 21. 



Larva pupated. August 1. 



Imago emerged. August 16. 



The imago was a male, of the form " terra." 



This in itself was sufficient to prove the identity of the 

 forms " ohscura" " hohleyi " and " terras Further, the 

 larva and pupa corresponded exactly with the coloured 

 drawings of those of Ps. imitator, Trim., as drawn by 

 Miss Margaret E. Fountaine, and published in the Trans- 

 actions of the Ent. Soc, Part I, 1911 (pp. 57-59, and 

 PI. X), thus bringing this form into the same category. 

 Miss Fountaine, however, makes no mention of the great 

 difference in the appearance and habits of the young 

 larva before and after the first ecdysis. 



I will now proceed with the detailed description of the 

 various stages. 



The Ovum. — When freshly deposited on the 16th June, 

 at noon, was of a uniform dull yellow colour. In shape 

 it was spherical, but slightly flattened at point of attach- 

 ment to the leaf: the surface being of a shagreen texture 

 and deeply sculptured into hexagonal cells. On June 18th 

 the periphery became clearer and less yellow, the centre 

 opaque and dull pinkish. On the 24th the centre became 

 black, and the outer parts white and semi-transparent. 



The Larva. — Finally, without further change in the 

 appearance of the ovum, at 9.15 a.m. on June 25th the 

 young larva ate its way through the shell, and at once set
