tudinally medianly carinate; pale rather stouter than in 
female. yes sordid pinkish. 
Striyil exceedingly minute, bluish black, subquadrate, with 
four broad rows of “ teeth.” 
?. Head very convex, facial impression and labium 
forming an ovoid, the base of which is continued slightly 
beyond the apical margins of the eyes; the impression is 
covered with short, dense, pale golden hairs. 
Head medianly longitudinally carinate. yes greenish. 
Long. 8°5-9 millim. 
Adelaide River, South Australia: British Museum. 
I am indebted to Mr. W. F. Kirby, F.L.S., for permission 
to describe the two preceding species. 
3. Corixa australis, Fieber. 
Corixa australis, Fieber, Abh. k. béhm. Ges. Wiss. (5) vil. p. 232, 
pl. i. fig. 15 (1851). 
Head punctate. Width of base less than that of either 
eye (as seen from above). 
Pronotum obtuse-angled, very rastrate. 
Pedes: intermediate tibiw rather longer than the unguiculi, 
which are much longer than the tarsi. 
6. Strigil comparatively large, suboval, truncated at both 
ends, bluish black, furnished with five or six rows of “ teeth,” 
the fourth or fifth being broken up into two or three dextro- 
laterally. 
Facial impression obovate, very large and deep, extending 
almost to the vertex; base of the interior impression curved, 
its lowest point in a line with the apical margins of the eyes. 
The female has not yet been described. 
I have not seen the type of this species, but two males 
from Tasmania in the British Museum accord with Fieber’s 
description and his figure of the male pale. 
] am acquainted with only three Australian Cortre, all 
very different:—C. australis, Fieber, apparently belonging 
to the “ limitata, Fieber,” group; C. eurynome, described 
above; anda species allied to sérvata, Linn., of which I have 
seen a single specimen. ‘Iwo species are also recorded from 
New Zealand :—C. arguta, Buch. White (nt. Month. Mag. 
xv. p. 161, 1878), and C. zealandica (figure, but no descrip- 
tion), Hudson (Klement. Man. Insects N. Z., 1892). 
There are doubtless very many species yet to be recorded 
from those countries.
