206 Mr. E. Meyrick's descriptions of 



6 and 7 separate or stalked, 8 anastomosing with 7 very shortly 

 near base. 



A cosmoi^olitan genus, but in New Zealand only repre- 

 sented by the wide-ranging A. ruhraria, which cannot 

 be regarded as indigenous. The separation or stalking 

 of veins 6 and 7 of the hind wings is an unreliable 

 character specifically, both forms occurring sometimes 

 in the same species (as in A. homodoxa). 



23. Acidalia ruhraria, Dbld. 



Ptychopoda ruhraria, Dbld., Dieff., N. Z., ii., 286, 

 Meyr., Trans. N. Z. Inst., 1883, 57; Acidalia 

 fifllinaria, Gn., ix., 454, pi. xii., 8 ; A. repUtaria, 

 Walk., 778; A. attrihuta, ib., 779; Fidonia 

 acidaliaria, ib., 1037. 



Norfolk Island (M(7f/«ezi') ; abundant throughout Eastern 

 Australia and New Zealand. 



24. Acidalia crossophragma, n. s. 



(^ , $ , 19 — 20 mm. Head and palpi ochreous-brown, band 

 between antennse white. Antennas whitish, ciliations in male 2^. 

 Thorax and abdomen whitish ochreoiis. Posterior tibite in male 

 with a dense tuft of long white hairs from middle above, tarsi one- 

 fourth of tibifE. Fore wings moderate, triangular, hind margin 

 slightly bowed ; whitish ochreous, sometimes thinly irrorated with 

 fuscous ; five obscure pale greyish ochi-eous waved shghtly curved 

 parallel lines, first before middle, nearly obsolete, rest between 

 middle and hind margin ; a black discal spot between first and 

 second ; a hind-marginal row of black dots, connected by a very 

 fine blackish line ; cilia ochreous-whitish, with two sharply marked 

 dark fuscous lines, second strongest. Hind wings moderate, hind 

 margin rounded ; colour and markings as in fore wings, but first 

 line absent, discal dot larger and placed on posterior edge of second 

 line, which is somewhat before middle. 



Easily recognisable by the two sharply marked dark 

 fuscous lines in cilia.
