Habitat: Australia-Nelson (Cairns), Queensland, 



Type: In the Queensland Museum, Brisbane, 

 the above female on a tag plus the head on a slide. 



Selitrichodella new genus. 



Female: Like Selitrichodes Girault but with 

 the folloAving additional characters: The antenna© 

 are 7-jointed, the funicle joints as long as the pedicel, 

 the club solid, a single ring-joint. The scutum has a 

 deep median sulcus, the scutellum four, two on each 

 side of the meson, the lateral sulcus far laterad and 

 narrower. The abdomen is subpetiolate, depressed 

 ovate. Posterior "wings acutelj^ pointed. Metallic 

 purple and yellow. Eyes with obscure pubescence. 

 Propodeal spiracle minute, round. 



Male: The same but the antennae 8- join ted, 

 four funicle joints, the first subquestetrate. Also 

 smaller and wdth a different color pattern. 



Type: The folio-wing species. 



1. Selitriclwdella mira new species. 



Female. 



Brilliant metallic imperial purifie, the abdomen 

 light lemon yellow with a broad purplish blacic stripe 

 down each side (lateral aspect) from base to 

 distal third or fourth. Legs and antennae concolorous 

 with the abdomen. Wings hyaline, the venation pale. 

 Head and thorax very finely coriaceus, shining, 

 impunctate; propodeum with lateral and median 

 carinae. Venation pale yellow. Distal two funicle 

 joints subequal, longest. 



(From nine specimens, similarly enlarged.) 



Male: The same but a fourth smaller, the ab- 

 domen narrower, the longitudinal purplish stripe 

 down each side absent; instead, the distal third of 

 the abdomen (dorsad) is metallic purplish. 



(From two specimens.) 



This most beautiful species was reared from, a 



lot of galls occuring on the leaves of the Cockatoo 

 Apple. The gall is inhabited by a caterpillar, but 

 appears to be di"pterous. It is along the midrib.
