IV PREFACE. 



structure of the eggs, and also to the groups as indicated in 

 the key to the Genera of Lycaenidae in Mr. de Niceville's 

 vol. iii of the ' Butterflies of India/ 



As in the previous volume I have to acknowledge with 

 thanks the help I have received from correspondents aud 

 friends. Mr. F. Moller, Darjiling, Major E. Stokes- 

 Roberts, R.E., Capt. W. H. Evans, R.E., Mr. P. Mackinnon, 

 Mussoorie, Mr. E. E. Green and Honorable F. M. Mackwood, 

 Ceylon, Col. C. Swinhoe, late Indian Army, Col. Waller- 

 Barrow, R.A.M.C., Lieut. C. C. Cunningham, 12th Kelat-i- 

 Ghilzai Regt., and others, have been most kind in collecting 

 or lending me specimens. 



I have also to express my thanks to the authorities of the 

 British Museum for the free access granted me to the 

 collections and library contained in the Natural History 

 Museum. Without this, I need scarcely say, the present 

 work could not have been accomplished. 



With regard to other works in this series, a volume on 

 Phytophagous Beetles, a concluding volume on the Rhyn- 

 chota, and short volumes on Land-shells and on Beetles 

 belonging to the family Cicindelidae are in active preparation. 

 Sanction also has been granted by the Secretary of State for 

 India for a volume on the Orthoptera, and for a third and 

 concluding volume of the Butterflies.
