Structure of some Australian Lepidoptera Homoneura. 605 
With regard to Palaeoses the case is clearer. The much 
reduced neuration and the absence of mandibles, maxillary 
palpi, and tibial spurs entitle it to family rank. These 
differences may indeed have been evolved from a form 
resembling Anomoses by a simple process of reduction, and 
I consequently regard the Palaeosetidae as derived from 
the Anomosetidae. It only remains to describe the new 
family, genus, and species. 
Fam. PALAEOSETIDAE, nov. 
Mandibles and maxillary palpi absent. Labial palpi well- 
developed. Antennae with whorls of bristles. Tibiae without 
spurs. Fore-wings with a single anal vein, 1 absent, 2 and 3 long- 
stalked, cell open between 3 and 4, internal vein of cell single, 
4, 5, 6 separate and parallel, 7 and 8 stalked and running to termen, 
9 and 10 long-stalked, 11 unbranched, 12 giving off a branch, and 
also with a humeral cross-bar near base. Hind-wings similar but 
without anal vein, subcostal not branched, and without humeral 
cross-bar. Wing-coupling effected by a non-deflexed jugum from 
base of dorsum of fore-wing. 
Gen. PALAEOSES, nov. (zadaidc, ancient, o7j¢, a moth). 
Palpi moderate (about 1), porrect, expanded with long rough 
hairs towards apex, terminal joint concealed. Antennae very short 
(about 7), similar in both sexes. Fore-wings with vein 9 to termen. 
Palaeoses scholastica, n. sp. (oyvodaotixdc, sluggish). 
36 2. 14-18 mm. ‘Head, palpi and thorax fuscous with some 
pale-ochreous irroration. Antennae fuscous, basal joints partly 
pale-ochreous. Abdomen fuscous; tuft large. Legs fuscous, 
irrorated, and tarsi annulated with pale ochreous. Fore-wings 
elongate-triangular, costa gently arched, apex round-pointed, 
termen long, bowed, oblique; fuscous, sparsely irrorated with pale- 
ochreous scales, more densely on dorsal and terminal margins; 
cilia fuscous, with indistinct pale-ochreous bars containing dark- 
fuscous points. Hind-wings subovate, rather narrow towards base, 
broadly expanded distally, apex round-pointed, termen rounded; 
cilia $; fuscous; cilia fuscous.

January; three specimens.
