of the second variet}' with a typical female fiilz'iis. It is exceed- 

 ing common, and is one of the few leafhoppers that can be con- 

 sidered as a pest of Eucalyptus. It is parasitized extensively in 

 the ova-stage b_\' Ptcrygograiiiina acuiuinata and as an nymjih by 

 Chalcogonatopus gigos. Xymphs of this or an alHed form are 

 parasitized by Prosaiiteoii cliclogynoidcs and Pipiuiciilus picrodvs 

 and cntciatov. 



2. idyia, sp. nov. 



LSlack ; base of vertex and liasal iiali of posterolatJial margin 

 of scntellnm, pale yellow ; a narrow line on the genae contiguous 

 with the lateral margin c,f the frons, a similar one on the pronotum 

 contiguous with the posterior margin of the eyes, a tiny wedge at 

 anterolateral angles cf scutellum, pale ferruginous; labium, 

 fore and middle legs (except ba^al two-thirds or more of fe- 

 mora) testaceous. Tegmina subhyaline. tinged witii ferrugi- 

 nous, veins (somewhat sulYusedly in most of them), med.an third 

 or more qf subcostal cell, blackisli ; basal two thirds of aiitesub- 

 costal cell, whitish subhyaline. N'ertex roundetl apically. strong- 

 ly striate transversely, formed as in 7'. fiiinis, but a little more 

 prominent anteriorly. Eyes as in T. fiilz'us. Frons basally 

 strongl}- striate transversely, apically aciculate punctate. Genae 

 with the apical margin less oblique than in T. fitlz'iis, and clypeu.s 

 shorter than in that species. Tegminal venation much as in 

 7'. fla-i'ipcs but the crc^s-vein on the brachial near the base, and 

 that towards the apex of the subcostal cl!, are straight, not ob- 

 lique; there are no cross veins in the clavus. .Second suba|)ical 

 cell extending apically beyond the others. 



Male: genital segments apparently nmch as in T. pii'c/iclh.'S 

 but in all the specimens they are rather shrivelled.

3. itonias, sji. nov. 



Appariiitly allied to 7". pn'clicUns, but differing by the form of 

 the genitalia and by the vertex being obtuse-anguhir. Face 

 immaculate, borders of the pieces rather more obscure, lateral 

 margin of frons fairly straight. .Sterna and st.rnites testaceous. 

 \'enation similar to pulcliclliis, but the median (inner discoidaP 

 cell is longer, the cr(,ssvein in the subcostal straight ; the first
