AUSTRALIAN HTMENOPTESA CHALCIDOIDEA, II.—GIBAULT. 169 



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

 with success with the Trichogranmiatidas. 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 Myinarida? as well. 



Trichogrammatida3 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 Trichogrammatida?, 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?. 



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

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

 ■perforator, Stetliynium lavmrsieri, S. cuvieri, S. vesalii, Campioptera gregi and Polynema 

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