Indian Museum Notes. 



[Yol.IIL 



With this object parasites from a number of different caterpillars 

 have been reared in the Indian Museumj and a representative series of 

 them has recently been examined by Herr F. M. Van der Wulp of La 

 Hague, who has made this interesting- group of iuseets his especial study. 

 The result of his examination, so far as the new species are concerned, 

 is given on pages 9 — 17 of this volume, and it here remains to record 

 the details of the caterpillars from which they were reared. The most 

 noticeable features are, firstly, that the Bengal silk worm fly [TricJiolyga 

 hombycisy Becher) also attacks the two destructive defoliating caterpillars 

 Dasychira thwaitesii, Moore, and Olene mendosa, Hiibn., and secondly, 

 that in no less than three instances the same species of caterpillar has 

 been simultaneously attacked by more than one species of Dipterous 

 parasite.
