entirely illusory; the former group is merely obtained by confounding 

 together a number of unrelated genera which happen to agree in having 

 vein 10 out of 8 (though even this is not constant), and is therefore 

 unnatural and artificial, whilst the latter is nominally based on the posses- 

 sion of raised types of scales in the cell of forewings, whereas in my opinion 

 these tufts are not merely sometimes, but usually, non-existent. 



14. Nymphula Schranck, 



Nymphula Schranck, Faun. Boic, 2, 162 (1802) ; type, stagnata Don. 

 Paraponyx Hiib., Verz., 362 (1826) ; type, stratiotata Linn. 



Antennae §. Labial palpi ascending, second joint with .projecting scales 

 beneath, terminal joint slender, somewhat pointed. Maxillary palpi with 

 apex loosely scaled. Forewings with 10 rising out of 8. Tibial outer spurs 

 half inner. 



An Indo-Malayan genus, spreading more or less into surrounding 

 regions. Larva aquatic, sometimes breathing by branchiae. The single 

 New Zealand species is an immigrant from Australia. 



76. N. nitens Butl., Cist. Ent., 2, 556 ; Meyr., Trans. N.Z. Inst., 1885, 130. 



Hamilton, Napier, Masterton, Christchurch, Lake Wakatipu. 

 Also common in south-east Australia. 



15. Musotima Meyr. 



Musotima Meyr., Trans. Ent. Soc. Lond., 1884, 288 ; type, aduncalis 

 Feld. 



Antennae f. Labial palpi more or less ascending, second joint with 

 evenly projecting scales beneath, terminal joint slender, rough-scaled 

 beneath towards apex. Maxillary palpi dilated with rough scales, trun- 

 cate. Tibial spurs long, almost equal. Forewings with 10 rising out of 8. 

 Hindwings with 7 out of cell before angle, separate from 6. 



Besides the New Zealand species there are a few others from Australia 

 and the Indo-Malayan region, and one from Brazil. 



77. M. aduncalis Feld., Eeis. Novar., pi. 135, 11. 



Whangarei, Auckland, Taranaki, Wellington, Nelson. 



78. M. nitidalis Walk., Cat., 34, 1317 : timaralis Feld., Reis. Novar., 



pi. 135, 23. 



North and South Islands, common in forest. Also widely dis- 

 tributed in Australia. Larva on Adiantum, and perhaps other ferns. 

 As it is sometimes very destructive to ferns in greenhouses, it might 

 easily be spread artificially. 



16. Diasemia Hiib. 

 Diasemia Hiib., Verz., 348 (1826) ; type, litterata Scop. 



Antennae f, in ^ fasciculate-ciliated. Labial palpi porrected, second 

 joint triangularly expanded with dense projecting scales, terminal short, 

 concealed. Maxillary palpi with apex expanded with loose scales. Tibial 

 outer spurs f of inner. 



A small widely ranging genus ; the New Zealand species is one of a 

 group of representative geographical forms indicating a former single species. 



79. D. grammalis Doubl., Dieff. N.Z., 2, 287. 



Whangarei, Hamilton, Napier, Masterton, Castle Hill.
