part of the latter apically acute-angled. Last sternitc truncate, 

 transverse, pygophor flattened basally, reaching a little beyond 

 apex of tegniina, not so long as ovipositor. 



Male: (of this species?) Head slightly roundly-angulate an- 

 teriorly, a little wider at eyes than in the middle. Last segment 

 roundly emarginate, valves about twice as long, elongate tri- 

 angular. 



Length (male) 8- (female) ii| mill. 



Hab. Queensland, Brisbane (Nov.. type), Bundaberg (Sept.- 

 Dec, males, female). 



2. iphiaitassa, sp. nov. 



Male: allied to the last, but differs as follows: 



Extreme base of frons pale yellowish white, bordered apically 

 with blackish, narrowl}-. Tegmina not mottled, immaculate, 

 veins more sparingly annulate with whitish. Legs not annulate. 

 Vertex distinctly angulate, a little wider in the middle than at 

 the eyes. Labium reaching to apex of middle trochanter. Last 

 sternite dark fuscous, truncate, about one-fourth or one-fifth 

 of the length of the pvgophor, which widens out a little apically.

rittoiiiessa, gen. nov. O'-* 



A^ertex very short, rather longer at the eyes than medianly ; 

 margin between this and frons angulate. but the top is actually 

 thickened and a little flattened, an ob-cure transverse, ventral 

 keel at about the middle of the eyes, apparently forming the 

 limit. The ocelli are on this thickened and flattened part, about 

 as in Tliymbris, and although ventral in aspect, are I think, on 

 tlic "vertex." Frons narrow, elongate. Tempora wide, anten- 

 nal ridges rather strong. A>rtex and pronotum transversely 

 striate. Clypeiis and geiiae strongly aiigii'afe, the a'^ieal part 

 declivous. Venation as in Thymbris, but the apical part of the 

 subcostal cell is longer and reaches the apical margin of the 

 tegmen.
