Itinctly nearer to the eyes than to one another, yellow brown, 

 i Tibiae and tarsi reddish pitchy. Tegmina vitreous, scarcely 

 I tinted, base and subcostal cell opaque, ferruginous; third apical 

 I cell elongate, narrow, interior side curving a little towards the 

 {exterior; first discoidal hemisphaerical, two-thirds the length of 

 the first. Horns a little farther apart basally than in A. iasis, 

 and a little shorter and lilunter. The venation in some exam- 

 l)les is irregular. 

 Length 5 mill. 

 Hab. New South Wales, Sydney (Feb.). 



3. curyiiomiis sp. nov. 



Fairly clase to the last, but the horns are shorter and more 

 depressed. Interior margin of third apical cell straight; first 

 discoidal cell smaller, about half as long as the second. Legs 

 less yellozinsh-iervuginons. 



Length 5 mill. 



Hab. Queensland, liundaberg (Sept. -Dec.) 



4. ? bispimis Stal. 



Jn the absence of species for comparison, several forms are 

 temporarily determined as above. It seems as much a Cen- 

 trotypus as an Acantlmchus. 



Hab. Queensland, Cairns (July-Aug.), Brisbane (Nov.) 



CLASSIFICATION OF THE FULGOROIDEA. 



Stal's classification of 1866, followed almost entirely by 

 authors since that date, although separating the various groups 

 fairiy well, places the last scz'cn in a parallel series, with more 

 or less overlapping characters, an obviously unnatural arrange- 

 ment. So many of the Indgoroid genera are unknown to me 

 in nature, however, that I am prevented from any thorough- 

 going revision and can only offer some hints. 



Hansen has laid great stress on the structure of the antennal 

 sensory organs. My own researches confirm this, but at pres- 

 ent I do not think it is practicable. Selected forms display the 

 characters very sharply, but in a large number, it is impossible 

 to see anything definite at a magnification of i'88 diameters, and 

 it is impracticable to focus a compound microscope nearer, with- 

 out dissection, in the case of such minute antennae as those of
