SUMMARY OF CONTENTS OF THIS BULLETIN. 



In Parts J and N of this Bulletin the Dryinidae are discussed, 

 their habits and structures being detailed. It is specially shown 

 that those forms which attack Jassids, while often superficially 

 lesembling- others parasitic on Delphacids, always differ essen- 

 tially in the structure of the chelae from the latter. Conse- 

 quently the same species or rather the same genus does not at- 

 tack both of these indiscriminately. The nature of the larval 

 sac is explained, and a similar sac is shown to exist outside the 

 g-rou]) in an anomalous insect (possibly allied to Eiiibolcinns) 

 ])arasitic on Orthoptera. It may be added that this is also the 

 case with some European Belytidae. which also form larval sacs 

 on small Jassids. The economic value of Dryinidae is discuss- 

 ed, and the effect of hyperparasites on their utility. Some spe- 

 cies reproduce parthenog-enetically, though males occur. Sixty- 

 two new species and fifteen new genera are described ; the ma- 

 jority being bred specimens. 



Part II deals with the parasitic Lepidoptera of the 1%-imily 

 Epipyropidae. Their habits are given and "the remarkable form 

 of the young larva is described. One species is parthenogenetic. 

 and no male of this is known. Six new species are described in 

 three new genera, all having been bred from larvae. 



In Part III the Stylopidae are discussed, their habits, the 

 efifect of their attack on their hosts, the frequent occurrence of 

 a parasitic fungus in connection with their attack, the structure
