590 Mr. F. P. Dodd on Ant-friend Lepidoptera. 
Townsville, Gus Mian (Dodd) ; from October to January, 
five specimens. 
Cyclotorna egena, n.sp. 
¢ 9. 10-15 mm. Head and thorax fuscous mixed with whitish, 
Abdomen fuscous. Forewings elongate, costa moderately arched, 
apex obtuse, termen very obliquely rounded; purplish-fuscous, 
sprinkled with dark fuscous and whitish ; a very obscure darker 
transverse discal spot at 3: cilia fuscous. Hindwings narrower and 
more pointed than in the other species, 3 absent; dark fuscous ; 
cilia fuscous. 
Townsville, Queensland (Dodd); two specimens. 
I note that the pupa is protruded from the cocoon on 
emergence; the antennal cases are separate, and remain 
entire after dehiscence. The secondary larval form has 
much resemblance to a woodlouse (Oniscus), probably 
partially due to adaptation to similar circumstances. The 
term “ant-friend” seems scarcely accurate, the moth 
appearing to have by far the best of the bargain; one is 
reminded of the crocodile styled “ protector of the poor” ; 
the unfortunate ant, blinded by his partiality for liquor, 
overlooks the fact that it is produced entirely at the 
expense of his own larvae devoured; the moth, on the 
other hand, is merely getting rid of a by-product of his 
digestive system, whilst obtaining free quarters, shelter 
and protection from enemies, and a permanent food-supply 
in all seasons. The whole life-history is most curious, and 
as an instance of double parasitism unique, so far as I know. 
On careful consideration of these insects I am of opinion 
that the genus is an isolated one, representing an early 
form of the Zineina. In the forewings vein 1b has a spur 
rising from the lower basal fork, analogous to a similar 
structure in the Psychidae ; vein 12 is exceptionally thick- 
ened and strong. In the hindwings vein 1b forms a long 
apical furcation (la and Ie being both also well developed), 
a structure apparently unique; it has a strong basal fork 
as well; vein 8 is also unusually thickened. I consider 
these characters sufficient to constitute Cyclotorna the 
type of a new family, Cyclotornidae.
