MEMBRA CIDJE. 
PTEROSTICTA RUBRILINEA. 
(Plate LI. figs. 4, 4a.) 
Very like Sextius virescens, but the suprahumeral processes are much more 
obtuse. They are porrect as in Oxyrliachis, and dark at their tips. 
The posterior process has a bright red streak continued over the dorsum. The 
tegmina have the nervures subdivided at their apices, and the bases are transparently 
stippled. Probably the live insects are green in colour, instead of bright ochreous, 
as found in cabinets. 
Size, 7x3 mm. 
Habitat .—Adelaide.

PTEROSTICTA SPRETA. 
(Plate LI. figs. 5, 5a.) 
Colour variable from bright yellow to sordid greenish. Pronotum with two 
short blunt suprahumerals, each having a rich brown stripe from its summit. 
Dorsal ridge nearly straight, pointed, and continued to the tips of the tegmina. 
Frons oval and rich brown, with conspicuous ocelli. Metopidium seen from the 
front square, with a broad brown band connecting the tips of the short horns. 
Legs short, flattened, and reddish-brown. Eyes placed in circular depressions. 
Tegmina elliptical and pointed. Neuration rather indistinct, but complex and 
reticulated. 
Size, 7x3 mm. 
Habitat. —Adelaide, Australia.

PTEROSTICTA RUBRIDORSATA. 
(Plate LI. figs. 6, 6a.) 
Suprahumeral processes obtusely pointed and dark fuscous in colour; the 
posterior apex sordid ochreous-red and stouter than the last species described. The 
tegmina pointed at the apices, hyaline, and marked by reddish nervures, the 
radials at their tips being subdivided by short transverse nervures; the base much 
stippled with transparent pores. Legs dilated and ferruginous. The front aspect 
shows the horns slightly recurved. The example figured is a female, and has a 
red line down the dorsum. 
Size, 8x5 mm. 
Habitat. —S. Australia, Adelaide.
