Probably nearest niphaula, Meyr., but differs by shorter 

 costal streak, narrower white streaks, and the oblique fuscous 

 bar. 



Hab. — 'Pinnaroo, South Australia; one specimen, in 

 July. 



Family TINEIDAE. 



ChRYSORYCTIS ( 1) IDIOCHROA, 11. Sp. 



d , 20 mm. Head pale ochreous-yellow. Thorax white. 

 Antennae ochreous. Palpi ochreous. Abdomen ochreous- 

 orange. Legs ochreous. Forewings elongate, costa gently 

 arched, termen very obliquely rounded; white; a fine ochreous 

 line along costa from base to three-quarters ; cilia pale 

 ochreous. Hindwings dull ochreous-orange; cilia as in fore- 

 wings. Underside of all wings dull ochreous-orange. 



Probably nearest ochracea, Meyr. ; the white forewings 

 should make it easily recognizable. 



Hab. — Broken Hill, New South Wales; one specimen, 

 in January. 



Trisyntopa, n. gen. 



Head with appressed hairs. Antennae moderate, in 

 male filiform, ciliations two, with strong basal pecten. Palpi 

 moderate, curved, ascending, second joint tolerably smooth, 

 terminal joint half of second, just reaching base of antennae. 

 Abdomen moderate. Posterior tibiae rough-haired above and 

 beneath. Forewings with veins 7 and 8 stalked, 7 to apex, 

 9 out of 7 above middle; 3 and 4 short-stalked. Hindwings 

 over 1, subovate ; 3 and 4 from a point, 5 approximated 

 to 4, 6 and 7 parallel. 



A curious genus not near any other known to me. The 

 neural characters are somewhat abnormal for this group, but 

 until further material is forthcoming it can remain here. 



Type euryspoda, Low, 



Trisyntopa euryspoda, n. sp. 



<3 , 25 mm. Head, palpi, and thorax ashy-grey-fuscous, 

 palpi paler beneath. Antennae fuscous, annulated with 

 darker, ciliations 2. Abdomen ochreous-grey, silvery-grey 

 beneath. Legs silvery-grey, anterior and middle tibiae and 

 tarsi infuscated. Forewings elongate, moderate, costa moder- 

 ately arched, apex rounded, termen rounded; ashy-grey- 

 whitish; veins, especially towards termen, more or less out- 

 lined with fuscous; an obscure elongate dot in cell; a second, 

 more distinct at posterior end of cell ; base of wing some- 

 what darker than rest; a somewhat obscure curved row of 

 more or less disconnected spots just before and parallel to 

 termen ; cilia grey-whitish, basal half fuscous. Hindwings
