account of their preoccupation. 



Moreover, I do net think MeHchar has correctly referred 

 Ledropsis. I Iiave not seen the types, but I beheve that Rlwtidus 

 and Riibria are synonymous with this, or very closely allied. The 

 nymphs of Eogypona (=^ ? Caniptclasuius ) and Rlwtidus ( := ? Le- 

 dropsis) are very different. The former are very flat, laminatelv 

 foliaceous. and exceedingly thin, while the latter are not unlike 

 the adults. 



Rlwtidus (=? Ledropsis). 



The female ultimate sternite is very similar in all the species 

 described by me. The posterior margin is slightly sinuate, with a 

 small median notch which is almost obsolete in ledropsifoniiis. In 

 viridescens, and inforuiis it is obtuse-angled or somewhat round- 

 ed ; in horrendus it is similar but mere acute; in uwustntiii, 

 iiigeiis and flavouiaenlatus it is distinctly rounded. 



Distant has described (1907 A. S. E. Belg. LI) : 



13. aeqiialis op. cit. 193. Queensland, and has transferred here 

 Ledra tcJiforinis, navicula and cuspidata Walker. This preoccu- 

 pies the "Rhothidns navicula' of Stal, from Queensland, which 

 is obviously not that Oif Walker ; for the Stalian species, I propose 

 tile name of stali. 



Ledropsis 

 Distant has described : 

 I. froggatti op. cit., 192 New South Wales 



Distant has also described : 



Jiikarnka (g. n.) typica op. cit. 190 Queensland 



In the list of unknown Australian forms, I omitted Rubria 

 sidnica (XeropJiIoea) Stal 1859 Eugenie's Resa. Ins. 288 ( Syd- 

 ney.) 



Tribe Stenocotini. 



This tribe differs from the Ledrini only in the position of the 

 ocelli, which are situated in elongate pits on the margin connect- 

 ing the vertex and the frons, and by the great emargination of 

 the vertev hasally. T know only tlirpp gfenera. all Anstralian, 

 which have been analyzed on p. 368 of my former memoir.
