508 DESCRIPTIONS OF AUSTRALIAN MICRO-LEPIDOPTERA, 



Hindwings broader than forewings, rounded-trapezoidal. Fore- 

 wings with veins 7 and 8 separate, vein 7 running to hindmargin. 

 ifindwings with veins 3 and 4 rising from a point, 5 approximated 

 to 4 at base, 6 and 7 separate. 



This is the typical genus of the largest and most simply- 

 organised group of the family, characterised by the separation 

 of veins 7 and 8 of f orewings, the origin of veins 3 and 4 of hind- 

 wings from a point, and the approximation of 5 to 4 at base. Of 

 the other Australian genera belonging to the group, Caccecia is 

 distinguished from Tortrix by the costal fold of male, Cryptoptih 

 by the tuft of scales on the costa of hindwings, Arotrophora by 

 the elongate palpi, and the deeply dentate antenna} of male, 

 having cilia arranged in tufts, Dipterina by the origin of veins 6 

 and 7 of hindwings from the same stalk, and by the antenna? of 

 male having long fine cilia arranged in two rows. Other genera 

 of the group (not Australian) are Teras, having vein 7 of fore- 

 wings running to costa, (Europe and America) ; Pandemis, having 

 an excavated notch in the antenna? of male above basal joint 

 (Europe and America) ; Auchotelcs, (South America) having very 

 short minute palpi ; and probably other genera not yet sufficiently 

 defined, whose distinctness it is not here necessary to examine. 



There is a considerable number of European and American 

 species, and the genus is probably of universal distribution. I 

 have twelve Australian species, and four from New Zealand, of 

 which the following is a tabulation : 



I. Eorewings white, with five black fascia? . . 1 . amcenana. 



II. Forewings dark fuscous, with three 



whitish fascia? . . . . . . . . 2. subfurcatana. 



III. Forewings pale greyish-ochreous or 



whitish, with dark longitudinal markings 4. aulacana. 



IV. Forewings with distinct transverse cen- 

 tral fascia?. 



A. Forewings light reddish-fuscous . . 3. ceramicana.
