0. nigra n. sp. (with a figure), is described by Froggatt in Proc. Linn. Soc. N.S.W., 
xxiii, 376 (1898). 
0. serrata Froggatt, Proc. Linn. Soc., N.S.W., xviii, 346, with figs. 24-26, Plate 
XVII. Galls very similar to those of 0. subrotunda. Found at Eendigo on an undeter- 
mined species of Eucalyptus. 
0. spinosa Froggatt, Proc. Linn. Soc. N.S.W., xviii, 341, with figs. 10-12, Plate 
XVI. Plentiful in several localities about Sydney, and common at Flemington on 
E. siderophloia . 
0. vsrriunila Froggatt, Proc. Linn. Soc. N.S.W., xviii, 338, with figs. 3-5, Plate 
XVII. Found on the young foliage of a Eucalyptus near a mine at Napoleon Reef, 
at 15 miles from Bathurst, N.S.W. Verricula in Agric. Gaz. N.S.W., ix, 498. 
0. pisiformis Froggatt, Proc. Linn. Soc. N.S.W., xviii, 343, with figs. 13 and 14 
of Plate XVII. This species is remarkable from the fact that it has been recorded 
from no less than four species of Eucalyptus, viz., E. mdliodora at Bathurst, E. robusta 
at Manly, E. piperita at Thornleigh, and E. resinifera at Sutherland. I have also seen 
it on E. corymbosa from Kendall (Dr. J. B. Cleland). 
Ascelis pramollis Schrader. In this genus the female larvae alone form galls. 
Figs, q and r, Plate III, show the gall and section. " The opening of the gall is not, as 
with Brachyscelis, in the top of the gall, but on the other side of the leaf (see fig. r). 
(Schrader.) Described more fully by Froggatt (Proc. Linn. Soc. N.S.W., xviii, 211, 
1893, with fig. 1, Plate VIII), who found them common in the neighbourhood of Sydney 
on E. corymbosa, and, in his experience, only on this species; the galls vary much in size. 
He also found them in abundance at Sutherland, near to Opisthoscelis subrotunda. 
On E. corymbosa, Ourimbah State Forest, Gosford (W. A. W. de Beuzeville). On 
E. hemiphloia var. albens at Coolamon (Dr. J. B. Cleland). 
A. attenuata Froggatt, Proc. Linn. Soc. N.S.W., xviii, 214, with figs. 4 and 4o 
of Plate VIII. The galls are very small, and found on the leaves of E. piperita at 
Thornleigh, near Sydney. 
A. Schraderi Froggatt, Proc. Linn. Soc. N.S.W., xviii, 213, with fig. 2, Plate 
VIII. 
" Gall an irregular rounded blister half inch in diameter." ..." This 
Ascelis gall was known to Schrader, who mentions them as ' large flat swellings on 
both sides of the leaves'; but he evidently considered it to be another form of A. 
proymollis. Though both grow on E. corymbosa in the same localities, yet I have never 
found both growing on the same tree." 
Ascelis ( ?) multitudinea Tepper, op. cit., p. 278, with Plate V, fig. 4, is a Psyllid- 
Collected at Marino, south-eastern district of South Australia, on a leaf " of one of the 
Stringybark Gums" (presumably E. capitettata). 
Carteria melaleuccB W. M. Maskell, in Trans. N.Z. Inst., xxiv, 55 (1891), with 
Plate XII, figs. 1-10. On an undetermined species of Eucalyptus, probably from 
Victoria.
