Acting Assistant, Botanical Department, British Museum.

“ Miss Lorrain Smith’s admirable treatise is as learned as it is 
comprehensive and exact. . . . The work could not have been done 
better ; in comprehensiveness and lucidity it is far in advance of any 
previous treatise on the group . The references to literature appear to be 
exhaustive, and the index is full.” — The Times Literary Supplement. 
TYPICAL FLIES 
A Photographic Atlas. Second Series. By E. K. PEARCE. 
With 125 photographs. Royal 8vo. 15s. net. 
” The -photographs are as good as any we have seen of this class of 
insect — a peculiarly difficult class to represent pictorially in any natural 
manner. . . . There are excellent short notes as to habitat, larval habits, 
and so on under the pictures. . . . We hope this volume may stimulate 
a wider interest in this fascinating group.”- — Nature on the First Series.
