6 — The Schedule in which it is suggested that the returns should be made is 

 enclosed herewith (Schedule A). It is desired that the return for each species be 

 made on a separate Schedule, and the Secretary will be glad to furnish a supply of 

 these Schedules to any one who may be willing to assist. 



7. — Since confirmatory evidence is of special value, the Committee are desirous 

 of receiving returns made independently by different persons for the same district. 

 It is of course hoped that returns may be obtained for districts in which the dark 

 forms are still anknown. 



8. — The Secretary will be glad to examine and prepare descriptions of any 

 illustrative specimens lent to him for that purpose, and in suitable cases arrange- 

 ments will be made for photographing such specimens. 



9. — Historical Evidence. As the changes in question have largely taken 

 place within living memory, it is hoped that those who have personal knowledge of 

 the facts may be induced to put them on record in such detail as is still possible. 

 Much information of a historical character is of course already printed in the 

 scientific journals, but a more detailed account of the facts would be of great value. 

 With this object a special Schedule (B), marked '' Historical," will be issued to 

 those who will fill it up. 



10. — On publication full acknowledgment will be made of all help received, 

 All communications should be addressed to the Secretary of the Evolution Com- 

 mittee, W. Bateson, Esq., F.R.S., Merton House, Grantchester, Cambridge.

[Ill the following notes the original observations, extracted from 

 letters received from my sister, are within inverted commas. My own 

 remarks thereon are within square brackets. — C. G. B.] 



Choerocampa ^son, Cr. — "These were reared from caterpillars found by a 

 neighbour on his arum-lilies, in a little flower house, and sent down here. Fortu- 

 nately, food being scarce, they soon spun up, or rather half buried themselves. The 

 caterpillars wore of a juicy green, and had a horn on their tails." 



Deilephila Schencki, Mosch. — "I have secured another beauty, at sunset, flying 

 round the peach blossoms. It looked like a living flame as its wings quivered 

 among the pink bloom. I only wish that you could have seen it alive. Some more 

 have been caught around the flowers of the Plumbago ; this pretty tender bush has 

 no thorns, but generally supports itself on a friend that has them ! " 



[This is indeed a beautiful species — of the size of D. galii — its fore-wings 

 longitudinally striped with ruddy-brown, olive-brown, and pale ochreous, with a row 

 of white lines down the middle ; hind-wings rose-pink, with a black hind border
