Ant-friend Lepidoptera of Queensland. 589 
several cocoons upon the tree I am perfectly satistied that 
they were formed by these Jarvae. It will be seen that 
this little caterpillar, with its flattened-out segments with 
their fine tissue edges, can adhere to a surface as closely 
as any scale. The head is visible when the insect is pro- 
gressing, but is withdrawn at the least alarm, and the 
edges of the segments are closed tightly down all round, so 
that the creature resembles a flat scale or a mere circular 
discoloured patch on the bark of the branch. Included with 
exhibits are some small Ichneumonidae which emerged 
from several of my pupae. 
SUPPLEMENT. 
By E. Meyrick, B.A., F.R.S. 
The three species mentioned above all belong to the 
genus Cyclotorna, Meyr., of which at present I know no 
other representatives. ‘To the generic characters as given 
by myself I may add that there is a tuft of scales from 
beneath eye, covering lower half of eye; and that in C. 
egena vein 3 of hindwings is absent, a modification probably 
connected with its reduced size.

Wales, 1907, 72. 
The darker suffusion towards costa, before middle of 
forewings, is sometimes extended to form an inwardly 
oblique fascia reaching more or less nearly to dorsum. 
The transverse-linear form of the discal mark distinguishes 
this species immediately from both the others, in addition 
to the larger size. 
Cyclotorna experta, v.sp. 
Q. 19-23 mm. Head and thorax fuscous mixed with whitish. 
Abdomen fuscous. Forewings elongate, moderate, costa rather 
strongly arched, apex rounded, termen obliquely rounded, dorsum 
strongly arched before middle ; fuscous, more or less sprinkled with 
grey-whitish, in one specimen mostly suffused with whitish, with 
scattered dark fuscous scales; an undefined patch of dark fuscous 
suffusion in disc before middle; a dark fuscous dot or dash on fold 
beneath middle, representing plical stigma; second discal stigma 
large, roundish, dark fuscous, anterior edge sometimes excavated so 
that it becomes crescentic: cilia fuscous, sometimes sprinkled with 
grey-whitish. Hindwings with vein 3 present ; rather dark fuscous ; 
cilia fuscous.
