ing undivided up to the apical cells. Appendix present. Wings 

 with supernumerary cell. Legs typically Tetigonian. 



14. aitrca, sp. nov. {.PI. XXIl, hgs. 6-7.) 



Pale golden yellow, tegminal appendix and underside paler 

 Eyes dark, and a small dark spot at base of appendix. 



Length 9 mill. 



Hah: Queensland, Kuranda (viii), arboreal. 



Two females only. I would have included this remarkable 

 genus in the Tetigoniini but it wo.uld have made too many ex- 

 ceptions in otherv^'ise fairly sharply defined group-characters. 



Subfam. 2. lassinae. 



Tribe i. lassuii. 



Vertex subquadrate, its sides and posterior margin elevated; 

 frons elongate, narrow; clypeus wider posteriorly than at its 

 base ; ocelli on the curve of the head ; usually only one subapicai 

 cell (but in Tharra Kirkaldy, the exterior discoidal is dividea by 

 a transverse vein thus forming another subapicai) ; wings with a 

 Bupernumerary cell. There are apparently 6 genera in this tribe 

 viz: lassus Fabricius (—Coclidia Germar and Daridiia Walker), 

 Terulia Stal, Pctalopoda Spangberg, Tinobregnms Van Duzee, 

 Tharra Kirkaldy and Palicus Stal ; the latter, which is an African 

 genus, I do not know ; Tltarra is Australian, the rest American. 



Tharra, gen. nov. 



Differs from lassus Fabr. by the possession of 2 subapicai cells 

 and the absence of transverse veins in the clavus. From TeruHa 

 ii dififers by the subapicai cells and by the straight anterior tibiae. 



Vertex flat, longer than wide, slightly declivious with regard 

 t':- the pronotum, abruptly elevated at the lateral margins, the 

 sides being at right angles to the disk,* which is very narrowly 

 sulcate longitudinally up to the apical margin of the eyes and is 

 produced a little, widened just apical to the eyes and rounded 

 obtusely. 



Eyes large, a little oblique ; ocelli a little nearer to the lateral 

 margins than the middle of the vertex. Frons elongate, nar- 



* This is probably a tribal character, as stated above, but as Spangberg's figures do 

 not show this clearly, I have mentioned it again in the generic characters.
