also deal with now), and a very few of the smaller genera, this fauna having 

 been of a very limited character, and further restricted by the nature of the 

 Antarctic lands through which the transmission was effected : (2) a mingled 

 Australian and Indo-Malayan element derived from Queensland and the 

 South Pacific by way of New Caledonia at a later period, conjectural] v the 

 Miocene, and including most of the smaller genera ; at the same time a 

 slight cross-immigration of the earlier element into Queensland took place 

 (Trachypepla, Sabatinca) : (3) a small Tasmanian element, which has made 

 its way (wind-borne) into New Zealand in quite recent times, the species 

 being identical and unmodified (e.g., Cateristis). A fourth element of arti- 

 ficially introduced species is now being superadded. 



The generic and family characters given only hold good for the New 

 Zealand species, and synonymy and references are restricted to those of 

 local use. 



1. Gelechiadae. 



Head with appressed scales. Labial palpi long, recurved, pointed, 

 usually acute. Maxillary palpi very short, appressed. Forewings with 2 

 usually from near angle, 7 and 8 stalked, 7 to costa. Hindwings more or 

 less trapezoidal, termen sinuate or emarginate ; 6 and 7 usually approxi- 

 mated or stalked. 



An immense family, abundant in all the main regions, but less prominent 

 in Australia, and only scantily represented in New Zealand. The species 

 are often inconspicuous and of retired habits, but are undoubtedly really 

 scarce here. 



1. Epiphthora Meyr. 



Epiphthora Meyr.. Trans. N.Z. Inst, xx, 77 (1888) ; type, mdanombra 

 Meyr. 



Basal joint of antennae with pecten. Labial palpi with scales of second 

 joint rough beneath towards apex, terminal joint much shorter, roughened 

 anteriorly. Hindwings under 1, termen abruptly emarginate beneath 

 acutely produced apex ; 3 and 4 rather approximated, 5 nearly parallel, 

 6 and 7 rather approximated towards base. 



A genus of some extent in Australia, and occurring also in the Indian 

 and African regions, but easily overlooked. The structural particulars 

 originally given by me are in part inaccurate.

Christchurch. Larva mining in leaves of Olearia avicenniaefolia. 



2. Megacraspedus Zell. 

 Megacraspedus Zell., Isis 1839, 189 (1839) ; type, dolosellus Zell. 



Basal joint of antennae without pecten. Labial palpi with second joint 

 tufted towards apex beneath, terminal joint as long as second. Hindwings 

 with termen emarginate beneath produced apex ; 3 and 4 remote, 5 nearer 

 6, 6 and 7 remote. 



A genus of wide distribution, more developed in Australia than else- 

 where.

Christchurch, Invercargill. Larva in seed - heads of Arundo
