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

 with supernumerary cell. Legs typicall>' Tetigonian. 



14. aiirca, sp. nov. (.Fl. XXII, hgs. (^-y.) 



Pale golden yellow, tegminal aj^pendix and underside paler 

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



Length 9 mill. 



Hab: Otieensland, Kuranda (viii), arboreal. 



Two females only. T would have included this remarkable 

 genus in the Tetigoniini but it would have made too many ex- 

 ceptions in otherwise fairly sharply detined group-characters. 



Subfam. 2. lassinae. 



Tribe i. lassiiii. 



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 divided by 

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

 bupernumerary cell. There are apparently 6 genera in this tribe 

 viz: lassits Fabricius {■=^CocUdia Germar and Daridna Walker). 

 TeruUa Stal, Petalopoda Spangberg, Tiiiobrcg)iiiis Van Duzee, 

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

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



Tharra, gen. nov. 



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

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

 ii differs by the subapicai cells and by the straight anterior tibiae 



Vertex flat, longer than wide, slightly declivious with regard 

 tc the pronotum, abruptly elevated at the lateral margins, the 

 sides being at right angles to the disk,* w'hic'h 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 cliaracters.
