of the second variety with a typical female fitli'its. It is exceed- 

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

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

 the ova-stage hy Ptcrygograniiua acuinniata and as an nymph by 

 Chalcogouafopus gigas. Nymphs of this or an allied form are 

 ])arasitized by Frosaiifcoii chclogynoidcs and Pipiiuculus picroclvs 

 and cruciator. 



2. idyia, sp. nov. 



.P)lack ; base of vertex and basal half of posterolateral margin 

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

 with the lateral margin qf the frons, a similar one on the pronotum 

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

 anterolateral angles of scutellum, pale ferruginous ; labium, 

 fore and middle legs (excejjt basal two-thirds or more of fe- 

 mora) testaceous. Tegmina subhyaline, tinged wita ferrugi- 

 nous, veins (somewhat suffusedly in most of them), median third 

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

 costal cell, whitish subhyaline. X'ertex rounded apically, strong- 

 ly striate transversely, formed as in T. fnlvus, but a little more 

 prominent anteriorly. Eyes as in T. fulvus. Frons basally 

 strongly striate transversely, apically aciculate punctate. Genae 

 with the apical margin less oblique than in T. fulvus, and clypeu.s 

 shorter than in that species. Tegminal venation much as in 

 T. flavipes but the crciss-vein on the brachial near the base, and 

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

 lique ; there are no cross veins in the clavus. Second subapical 

 cell extending apically beyond the others. 



Male: genital segments apparently much as in T. pu'.chellns 

 but in all the specimens they are rather shrivelled. 



Length 5^ mill.

3. itouias, sp. nov. 



Apparently allied to T. pulchellus, but difTering by the form of 

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

 immaculate, borders of the pieces rather more obscure, lateral 

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

 \'enation similar to pulchcllus, but the median (inner discoidaH 

 cell is longer, the crossvein in the subcostal straight; the first
