Antennas and legs fuscous, club of antennae white beneath. Ab- 

 domen greyish-fuscous, two anterior segments yellow. Fore- 

 wings elongate', moderate, costa nearly straight, apex pointed ; 

 dark fuscous, suffusedly iiTorated with white; markings dark 

 fuscous ; a fine streak along lower edge of cell, from near base 

 to posterior extremity, somewhat interrupted before middle ; a 

 short ochreoiis dash beneath anterior extremity ; a streak of 

 ochreo'us before termen from near apex to anal angle, contaiji- 

 ing 2 black spots near apex, and edged anteriorly throughout by 

 an obscure line of fine blackish scales ; veins more or less out- 

 lined with fuscous; cilia light fuscous, with median and ter- 

 minal white lines, more pronounced towards and ai'ound apex. 

 Hindwings with termen emarginate, apex pointed ; lights 

 fuscous ; cilia greyish-fuscous, becoming ochreous at base. 



Allied to tricliomhrous, Lower, but differs by fuscous lines of 

 forewings, and especially by the ochreous streak before the ter- 

 men, a character not shared by any of its allies, and which dis- 

 tinguishes it at once. 



Broken Hill, New South Wales ; eight specimens in August 

 and September. 



Ypsolophus argonota, n. sp. 



Male and female, 10-12 mm. Head, thorax, palpi, legs and 

 antennae white, antennae mixed with fuscous on terminal half. 

 Abdomen whitish, two anterior segments pale ochreous. Fore- 

 wings elongate, moderate, costa nearly straight, apex pointed ; 

 7 and 8 out of 6 ; white, very minutely irrorated with blackisJi 

 throughout, leaving costal edge obscurely white ; cilia ochreous- 

 whitish, with a few blackish scales at base. Hindwings with 

 termen emarginate, apex pointed, produced ; light fuscous ; 

 cilia greyish-ochreous. 



Known from its allies by the absence of any definito markings 

 and whitish coloring. It is nearest cycnoptera, Lower, but 

 differs in its smaller size and absence of longitudinal white 

 median streak. 



Broken Hill, New South Wales ; three specimens in October 



I formerly regarded this species, and its allies as species cf 

 Paltodora, Meyr., but Mr. Meyrick referred them tO' the pre- 

 sent genus, and altliough the characters do not agree with 

 those given in his ''Handbook of British Lepidoptera," I place 

 them here until the group is revised. All those I have re- 

 cently examined from this region have veins 7 and 8 out of 6, 

 and 2 and 3 widely remote at base ; the hindwings (which are 

 emarginate) having 3 and 4 connate, 5 somewhat approximated 

 to 4, and 6 and 7 stalked. This latter character would sepa- 

 rate them from Paltodora. The following species is very 

 -different in appearance, and the neuration is quite different, 

 i.e., 2 and 3 and 7 and 8 of forewinirs are stalked, and hind-
