56. Contribution to our knowledge of Indian Earwigs. 
By Matcotm Burr, D.Sc., M.A., F.ES., &c. 
Since the publication of the half volume on Dermaptera in 
the Fauna of British India series, substantial additions have 
been made to our knowledge; the classification has been re- 
vised, and in the following pages, sixteen species are added to 
the list, of which eleven are new to science: several of the 
others have been described since the appearance of the half 
volume in question, and two or three genera are added to the 
Indian list, and several imperfectly known species are here dealt 
with more fully. 
The Pygidicranidae are enriched by the inclusion among 
them of the Hchinosomatinae, and also some Ethiopian and 
Neotropical subfamilies. 
The Labiduridae are not much affected, except by the 
removal of the Echinosomatinae. 
The Labiidae have been profoundly altered by an outline 
revision published by me in the Deutsche Entomologische 
National-Bibliothek, No. 8, pp. 58-61 (1911) : the new arrange- 
ment is referred to below. 
The Chelisochinae are given the rank of a family, but other- 
wise are not much altered. 
The Forficulidae are altogether recast: the subfamilies 
- represented in India are as follows :— — 
Anechurinae, in which the doubtful genus Lipodes is pro- 
visionally ranged: Homotages is removed to the Forficulinae 
which is enriched by several other non-Indian genera, several

sels, to which the reader is referred for further particulars. My
