new Australian Hesperiide. 437 
two well-separated vitreous spots on the disk at two thirds of 
their length. 
Underside light grey, dusted with brown; base and lower 
part of fore wings blackish, the yellow costal fold well- 
marked, the spots below the discoidal spot and the outer one 
on the submedian nervure smaller than above ; fringes rufous 
brown, the black spotting rather indistinct. Posterior wings 
uniform light grey, dusted with brown, with two rows of 
obsolete blackish spots, in the outermost row of which the 
vitreous spots are placed; fringes grey, with large square 
black spots. 
May be distinguished from any described species by the 
two vitreous spots on the hind wings. The British Museum 
has undescribed species from Port Darwin and ‘Tasmania 
which exhibit this character, but not the comma-like form of 
the third subcostal vitreous spot. 5 
Telesto arsenia. 
Telesto arsenia, Plotz, Stettiner entomologische Zeitung, Ixy. p. 384 
(1884). 
Exp. 1 inch. 
Female.—Upperside brown, with greenish hairs towards 
the base. Fringes white, rather indistinctly spotted with 
brown. Anterior wings with seven vitreous spots—one trans- 
verse, at the end of the cell, three small, contiguous, sub- 
costal, slightly oblique, two between the median nervules, and 
a very small one below them on the submedian nervure. 
Underside grey, densely scaled, but with no distinct 
markings, except the vitreous spots of the upperside. 
Antenne black, narrowly ringed with white, and white 
below ; club rufous at the tip beneath. Body brown; thorax 
clothed with green hair above ; orbits and palpi beneath white, 
the latter densely clothed with white hair. 
It is often difficult to be sure of the identification of Plétz’s 
species; but the specimen described above appears to agree 
with the characters of his 7. arsenia. The locality which 
he gives is simply ‘‘ New Holland.” 
Hesperilla perornata. 
Exp. 1} inch. 
Female.—Black, the body and base of the wings covered 
with long yellowish-green hair; head mostly white, banded 
with black above, before, behind, and between the antenna ; 
tips of palpi ferruginous; antenna black, with a whitish 
longitudinal streak towards the base of the club beneath: 
under surface of thorax densely clothed with yellowish hair,
