obsolescent. The third segriient of each of the tarsi is blackish, 

 while the apical marg-in and apical third of the costal and com- 

 missural margins are smoky, the tibiae apically more or less so. 



Length: 15I mill. 



Ha'b: Queensland, Cairns (viii); Melichar records it from 

 Papua. 



2. ? atouiaria (Walker). 

 This form, from Tasmania, is unknown to me. 

 Siphanta Stal. 



Siphanta Stal, 1866, Hem. Afr. IV, 238; Melichar, 36. 



Melichar has noted two species from Australia, Schmidt add- 

 ed one last year, and I have now added eigiht, but it is probable 

 t'hat there are more, even in the material I have examined, as 

 the species appear to run very close. They are diiihcult to char- 

 acterize, as the only differences seem to be small, but constant, 

 points. Mr. Perkins tells me, however, that thev arc quite dis- 

 tinct in the field. 



I. galcata, sp. nov. (PI. XXXH, fig. 11). 



Distin'gtiished from the other Siphaiifas by the narrow, elon- 

 g"ate vertex, etc. 



Brig^ht green (fading to yellowish green partly or wholly), 

 greenish testaceous beneath; apical margin of teg-mina and an- 

 terior margin of vertex narrowly sanguineous. Vertex longer 

 than pronotum, lateral margins roundly converging in a round- 

 ed acute angle. The eyes are much more prominent and the 

 pronotum more prominent anterolaterally than in 6^. acuta. 

 Teg-mina very thickly set with small reddish brown g'ranules, 

 leavin'g" one small, naked spot of varying- extent in the middle 

 of each reticulation. Reticulations very large; apical margin 

 subtruncate obliquely, sutural angle acutely produced. 



Length: 9- 11 mill. 



Hab: Queensland. Cairns (vii-viii). Nelson (vii). 



2. acuta (Walker). (PI. XXL f. 2). 



Pocciloptcra acuta Walker, 1851, List. Hom., 448.
