2. perkinsi sp. nov. 



Close to E. dilatata, but cannot be that species, as it is much 

 larger, the vertex longer and not tapering during the api.al 

 two-thirds, about as long as the thorax and abdomen together. 

 The specks on the tegmina are smaller and not ocelliform, are 

 at least twice as numerous, the apical part of the tegmina being 

 well sprinkled. The coloring is t'hat of E. dilatata, but the teg- 

 minal markings are, as a whole, paler. In profile the serrations 

 of the 'head are flatter and s'hallower. 



Length: 27 mill. 



Hab: Queensland, Bundaberg (xij, bred; arboreal. 



Etiriiw psyche, gen. nov. 



The type of this was one of the original species of Eiirysthcits, 

 but can scarcely be included therein. It differs more particu- 

 larly by the different form of the head, the vertex at base bemg 

 narrower than an eye. Tegmina decumbent (in Eiirystheus they 

 are subtectiform), costa scarcely arched. Pronoturn with sub- 

 lateral subtransverse arched keels. 



I. obscurata (Fabr.) 



Fidgora obscurata Fabricius 1781 Spec. Ins. II, 315; West- 

 wood 145, PI. 12, f. 7. 



Length: 20^-21 mill. 



Hab: Queensland, Bundaberg (xi), Brisbane (vi), ar'boreal. 



There is a nymp'h of an allied form, in which the cephalic pro- 

 longation is sensibly widened anteriorly. This nymph, like all 

 those of this sub-family, is liberally endowed with sensory or- 

 gans. The vertex has them literally everywhere it is possible to 

 crowd them; on the ventral part of the prolongation there are 

 none and only a few on the frons proper; none on the clypeus. 

 They are sparser, but still numerous, all over the nota, tergites 

 and even on tihe tegminal pads. 



Length: 11 mill, width 4^ mill. 



Hab: Brisbane (xi). 



From Sydney (i), there are two specimens, in which the head 

 is much longer tlian in any of the other forms and is spatulate 

 anteriorly. The spatulate part is crowded with sensory organs, 

 but there are comparatively few others on the head. Those on 

 the nota and abdomen much as in the Brisbane forms.
