176 DESCRIPTIONS OF ATJSTRAILIAN MICBO-LEPIDOPTERA, 



Op. gephyrsea, n. sp. 



$ ? . 3"-3". Head, palpi, thorax, and legs snow-white, tarsi 

 slightly infuscated. Antennae ochreous-fuscous, very slenderly 

 annulated with white, basal j oint white . Abdomen fuscous-grey . 

 Fore-wings snow-white, extreme edge very slenderly blackish ; 

 a rather broad oblique blackish-fuscous spot on middle of costa, 

 and a strong oblique fascia-form blackish-fuscous spot from before 

 middle of inner-margin, uniting to form an angulated fascia, 

 rarely not quite meeting ; a very oblique black streak from f- of 

 costa to apex, anteriorly broadly edged with fuscous ; a second 

 similar one immediately following it, partly in costal cilia, rather 

 less oblique ; a small black apical spot ; cilia whitish round apex, 

 tips suffused with fuscous, sometimes with a faint perpendicular 

 streak above apical spot, hind-marginal cilia fuscous-grey. Hind- 

 wings and cilia fuscous-grey. 



Eeadily distinguished from the preceding by the dark hind- 

 wings and usually perfect fascia. Apparently rather scarce; 

 taken on fences in Sydney in October. 



ATALOPSYCHA, n. g. 



Head smooth, with appressed scales ; no ocelli ; tongue very 

 short. Antennae shorter than fore-wings, filiform, with a small 

 eyecap. No maxillary palpi. Labial palpi short, drooping, 

 filiform. Fore-wings elongate, narrow, pointed. Hind-wings 

 narrowly lanceolate, less than % of fore-wings, cilia thrice as 

 broad. Abdomen moderate. Legs slender, posterior tibisa long- 

 haired. Neuration (?). 



The single species has an extraordinary superficial resemblance 

 to ucculatrix, and might easily be confused with some of the 

 paler species, yet structurally it is very distinct, since the labial 

 palpi are plainly visible, and the head is not rough. Generally 

 it is more difficult to distinguished from Phyllocnistis, especially 

 as I have not been able to examine the venation, although it 

 certainly does not belong to the immediate neighbourhood of
