 Aphides, allusion having been made to that subject in p. 347. 



PROSODES ATER. 



Dr. Reinhardt gives the following names of Chalcidiao that are 

 connected with Aphides, either immediately or by an inter- 

 vening link : — 



"(1) Coryna clavata, Walk.; (2) Cyrtogaster vulgaris, 

 Walk.; (3) Diplolepis aphidis, Bouche ; (4) Chrysolampus 

 suspensus, Nees ; (5) Eurytoma aenea, Nees ; (6) Pteromalus 

 aphidivorus, Foerst. ; (7) Mesosela elongata, Walk. ; (8) 

 Agonioneurus subHavescens, Wesiw. ; (9) Chrysolampus 

 aphidiphagns, Batz. ; (10) Chrysolampus seneus, Bafz.; 

 (11) Tridymns Aphidum, Batz. ; (12) Myina Chaonia, 

 Walk.; (13) Callimome auratus, Enc. M. ; (14) Spalangia 

 nigra, Lair.; (15) Hypsicamara Ratzeburgi, Foerst.; (16) 

 Agonioneurus flavicornis, Foerst.''^ 



The same author partly supplies what is wanting in this 

 list, — the priority of the names, the adjustment of the 

 number of species, and what part they take in the mutually 

 antagonistic agencies by which the balance of created life is 

 maintained, or what species destroy Aphides, and what are, 

 as he terms them, " after-parasites," or limit the number of 

 these destroyers.
