AUSTRALIAN EYMENOPTEBA CHALCIDOIDEJ . II.—GIEAULT. 169 



all that I have found necessary or desirable in studying the MymaridsB. They have been used 

 with success with the Trichogrammatidas. Forms of the latter should never be allowed to dry 

 and color descriptions preferably should be made before mounting in balsam. This applies 

 to the delicate phragma-bearing Mymaridse as well. 



Trichogrammatidaj are collected in the same manner as described for the Mymaridse. 

 When clearing with heat, it is best in all cases to make the application as gentle as suffices; 

 with the Triehograinmatidro, it is necessary to remove the head and mount it under a cover 

 of its own so that pressure can be applied to the antenna 1 . 



The following Mymaridae are common in their habitats: Alaptus globosicornis, austra- 

 liensis, Dicopus psyche, Gonatocerus comptei, G. cingulatus, Anagrus armatus, Paranagrns 

 perforator, Stethynium lawirsieri, S. cuvieri, S. vesalii, Camploplcra gregi and Polynema 

 .poincarei. " Common" means " frequently met with."
