new Australian Hesperiidce. 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. 



Telesto arsenia. 



Telesto arsenia, PliJtz, Stettiner entomologisclie Zeitunir, Ixv. 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. 



Antenna 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 Plotz's 

 species ; but the specimen described above appears to agree 

 with the characters of liis T. arsenia. The locality which 

 he gives is simply " New Holland." 



Ilesperilla 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 antennaj ; 

 tips of palpi ferruginous ; antenme black, with a whitish 

 longitudinal streak towards tlic base of the club beneath : 

 under surface of thorax densely clothed with yellowish hair,
