The groujis of Lamelliconi beetles comiirised in tlic ibiii- 

 volumes published between 1910 and the present time, and in 

 the present volume, which is the last, have not followed am- 

 natural sequence, but have been dealt with only as the 

 materials necessary for the purpose have been foinid adequate. 

 The largest subfamily, the Melolonthin^, the very great 

 majority of the types of which are in Germany, has been 

 omitted for reasons which it is perhaps imnecessary to 

 exi)lain. The preparation of the present volume has been 

 made possible by willing help from many kind friends, who 

 have allowed me to study at leisure the specimens in their 

 charge and, in too many cases, to retain them for a veiy Ic^ng 

 time. Through their co-operation I have been able to cxamme 

 ty])e-specimens of nearly every sjjecies, known to inJiabit 

 India or Burma, of the two families dealt with here. Fortius 

 I must ackiaowledge my indebtedness in the first place to two 

 old and lamented friends, ardent entomologists and earnest 

 workers for international goodwill in two once-friendly nations 

 \\Iii(li, it is to be hoped, may in time to come prove worthy 

 of sucii citizens, the late Dr. Walther Horn, of the Deutsches 

 Entomologisclies Institut, Berlin, for the loan of the tyi)es 

 of Kraatz, Zang and others preserved in that institution, and 

 the late Dr. K. Gestro, of the Museo Civico di Storia Naturale 

 in Genoa, for the loan of Boileau's Burmese types. Dr. Gestro's 

 assistant. Dr. Capra, and his successor, Dr. Oscar de Beaux, 

 have also given all possible helj), for which I desire to exjjress 

 my gratitude.
