NOTES ON THE LIFE=HISTORY OF ALUCITA GRAPHODACTYLA. 
Read 20th October, 1908, by ALFRED J. WILLSDON. 
At our last meeting, on October 6th, I exhibited some living 
specimens of this interesting insect — interesting inasmuch as it is 
comparatively new to our List of British Lepidoptera, and that, as yet, 
not much is generally known of its life-history. 
The ova of graphodactyla are laid for the most part on the petals of 
the flower of a species of Gentian, known as Gentiana pnemnonanthe, 
a somewhat rare and local plant, and occurring in parts of Dorsetshire 
and Hampshire. They are laid in an irregular manner and are but 
slightly attached to the flower. The egg is a flattened oval in shape, 
length ^ S s ths of an inch, width ^^ths, diameter ^f ¥ ths. They lack 
the symmetry and beautiful decoration of the ova of the more highly 
developed Noctuae. The colour is bright translucent apple green. The 
envelope is shiny, having the appearance of being oiled, and the reflec¬ 
tions are opalescent. The surface is very irregularly reticulated in 
crude hexagons arranged in parallel rows, which coalesce at the 
extremity. The lower end of the egg is oval and the upper end 
truncated. 
The larva appears to feed exclusively on the ovaries of the flower.
