are all very small. and exceedingly fragile, and frequently can- 
not be identified without the life-history being known ; in fact a 
number of species have been set up on the lower stages only, 
the imagos not yet being known, and this practice should be, 
I think, rigidly condemned. The species of the world are listed 
by Kieffer in the Genera Insectorum, Fasc. 152. Some notes 
are given by Mr. Y. Ramachandra Rao on gall flies on Indian 
grasses! and Mr. E. P. Felt has described a few new Indian 
M ycetophilidae—Fungus gnats. Van der Wulp gave 23 
species and but few have been described apart from the 110 set 
up by me in the first ‘‘ Fauna” volume. These include 38 species 
of Sciara, which group I decline to regard as a separate family.

Hammatorhina bella, Loew, from Ceylon was known till com- 
paratively recently, but three others have lately been described,
