 black dots ; the segments below well accentuated by black.

This variety is also generally a darker and bolder looking 

 insect that the 2 of the type form. The anterior wings 

 are more rounded at the apical angle ; on the upper side 

 the light rays are shorter and broader, and more shaded 

 by brown atoms ; the posterior wings have more yellow, 

 and more white on them ; on the under surface the corres- 

 ponding white spaces of the type form are almost entirely 

 replaced by yellow ; and the abdomen is yellow instead of 

 being bluish-white as in the type form. A considerable 



difference may be remarked in the form of the anterior 

 wing cell of the $ . Altogether considered, Sulaensis con- 

 stitutes a very good subspecies. 



Habitat, Mangoli, Sula Islands. (Doherty). 



I here take this, my earliest opportunity of expressing 

 the great regret I felt when learning some time ago of the 

 untimely death of Mr. Doherty, in Africa. It is due to the 

 memory of the deceased gentlemen to say that we are all 

 deeply indebted to him for the knowledge and possession 

 of the many beautiful and interesting species of insects of 

 all orders, which his enterprising energy and love, as a 

 collector in oriental lands, brought to us. All science is 

 benefitted by the labours of such men as he. As in the 

 experience of many other explorers for Zoological purposes 

 his health suffered gradual deterioration, until an attack 

 of the terrible and mysterious disease Beri Beri necessitated 

 his return for a time to his home in America, in hope of 

 a restoration. After a considerable period of rest, he was 

 again in England, en route for Africa, for a new collecting 

 expedition ; but it seemed evident to some of those who 

 saw him that he was not in a fit state of health to venture 

 again in a tropical climate, with its hardships and dangers ; 

 apparently he was more hopeful of his condition than his 

 friends were, and so he started on his new enterprise, to 

 succumb soon after his arrival in Africa. O ! the pity of 

 it ! But his courage and perseverance, like that of other 

 martyrs in the cause of science, are worthy of our fullest 

 gratitude and admiration.
