AUSTRALIAN HYMENOPTERA CHALCIDOIDEJ. I.—GIBAULT. 153 



along meson of abdomen in a line from base, dusky black. Thus much like the species nu 



but more robust, the antennal club lacks the prominent terminal spine and the mesothorax has 



a complete median sulcus. The legs are dusky. 



From one male taken by sweeping secondary forest growth, May 23, 1914. 



Habitat: Gordonvale (Cairns), Queensland. 



Type : No. Ey 8444, Queensland Museum, Brisbane, the male specimen on a slide. 



Tribe TRICHOGRAMMATIXI. 

 Genus TRICHOGRAMMA Westwood. 



1. TRICHOGRAMMA AUSTRALICUM Girault. 



In Java (Pasoeroen) this species parasitizes the eggs of Cliilo infuscatellus, au unknown 

 'tortricid associated with cane, Grapholeta schistaceana and Diatrea striatal).*. In specimens 

 of this species reared from Chilo my attention was called by P. van der Goot to the presence on 

 the male and female antenna of the minute bladder-like appendages resembling conidial spores 

 (and thought characteristic of Trichogrammatoidea) . In the specimens sent me I observed 

 these on the female funicle. Sometimes the female abdomen bears two broad black bands one 

 at base, one at tip; it may be wholly blackish to jet black. 



I have a female from moth eggs, Chindera, Tweed River, New South "Wales, May 13, 

 1914 (A. P. Dodd) and many specimens from a mass of noetuid eggs on Melaleuca, forest, 

 Gordonvale, June 1, 1911. 



This paper taken witli Part I and the first supplement completes our present knowledge 

 •of the Australian Trichogrammatidas. Students of the group should consult my rather full 

 treatment of the world's genera now in course of publication in the Bulletin of the Wisconsin 

 (U.S.A.) Natural History Society. 



Students of this group must always be thorough and careful since the minute forms 

 contained therein have proved betes noires to many of the most acute Hvmenopterologists and 

 in studying them Ave must be certain to forsake our usual confidence and be content to feel the 

 way with Caution and Diffidence as constant companions. 2 



The following members of the family are common in their several habitats: Neobrachista 

 fasciata; TJfens fiavipes; Oligosita pulelira, Oligosita minima, Oligosita sacra; Tumidiclava 

 ciliata; Trichogramma australicum and Abbclta subfiava. 



- Methods of collecting and describing members of this family are given in the second supplement of Part II.
