SPOLIA ZBYLANICA. 
2. —List of Species found in Ceylon. 
I have recognized the following species of the Anophelinae in 
Ceylon, and Mr. Green of Peradeniya has found one species, 
Nyssorhynchus maculatus , which I have not found, but which is 
included to make the list complete. The names are those given 
in Theobald’s Monograph on the Culicidae of the World, vol. III. 
(1) Genus Myzomyia (Blanchard) :— 
Species 1 : Myzomyia Rossii (Giles). 
Species 2 : Myzomyia culicifacies (Giles). 
Species 3 : Myzomyia Listoni (Liston). 
(2) Genus Myzorhynchus (Blanchard) :— 
Species 4 : Myzorhynchus barbirostris (Van der Wulp). 
(3) Genus Nyssorhynchus (Blanchard):— 
Species 5 : Nyssorhynchus maculipalpis (Giles). 
Species 6 : Nyssorhynchus fuliginosus (Giles). 
Species 7 : Nyssorhynchus Theobaldi (Giles), found 
by Mr. E. E. Green. 
(4) Genus Pyretophorus (Blanchard) :— 
Species 9 : Pyretophorus jeyporensis (Theobald). 
(5) Genus Cellia (Theobald) :— 
Species 10 : Cellia argyrotarsis (Robineau-Desveidy). 
The most common are the Myzomyia Rossii, Myzomyia culici¬ 
facies, Myzorhynchus barbirostris. The Anophelinae found in 
Ceylon are the same species as those found by Stevens, Christo¬ 
phers, James, and others in India, and are different from those of 
Africa and America. 
A doubtful species is. noted, Nyssorhynchus Jamesii, by Dr. 
Philip, from Mutwal, Colombo, named from a damaged specimen. 
3.—Conditions of Life. 
Ceylon, with its damp warm climate and its abundant collection 
of water in rivers, wewas, pokunas, kulams, paddy fields, &c., is 
very suitable for the life of Anophelinae. But the conditions 
under which they exist at the end of the dry season can hardly 
be said to be the most favourable. The tanks are shrunk and 
dried up, the rivers are very low, and small pools, except as the 
remnants of much larger collections, are not in existence ; but 
Ceylon is peculiarly well supplied with water from the two wet 
seasons of the south-west and north-east monsoons, and by the 
system of irrigation tanks or wewas, by its numerous rivers, by 
its smaller collections of water in pokunas, kerLeys, wells, and 
paddy fields, and therefore even at the end of the dry season there 
is some water at places scattered all over the Island. I have
