GEACILAEIADyE. 



Head smooth, or rough on crown (not in New Zealand 

 genera). Antennae nearly as long as fore wings or longer, 

 simple. Maxillary palpi developed. Labial palpi slender, 

 ascending. Fore wings with vein 1 simple, 11 from before 

 middle of cell. Hindwings lanceolate or linear, cell open. 

 Larva 14-legged. 



The New Zealand species of this family have aj^parently 

 no near specific relationship to the Australian ; possibly they 

 have more affinity with the South American, which are in- 

 sufficiently known.

Geacilaria, Z, 



Head smooth ; ocelli absent or rarely present ; tongue de- 

 veloped. Antennae 1 or over 1, in male filiform, slender, basal 

 joint moderate, without pecten. Labial palpi long, curved, 

 ascending, smooth-scaled, second joint sometimes loosely 

 scaled beneath towards apex, terminal joint almost as long as. 

 second, acute. Maxillary palpi moderately long, filiform, por- 

 rected. Middle tibite sometimes dilated with scales, posterior 

 tibiae smooth-scaled. Forewings with vein 1 simple, 2 from |-, 

 3 sometimes absent, 4 and 5 often approximated, 7 to costa, 

 11 from before middle or near base, secondary cell sometimes- 

 well defined. Hindwings about ^, lanceolate or linear-lanceo- 

 late, cilia 4-5 ; 3 sometimes absent, cell open between 4 and 

 5, 5 and 6 stalked, their stalk sometimes continued to base of 

 wing, 7 from angle of cell, or rarely out of 6. 



The larvae are usually leaf-miners, or less commonly roll 

 leaves into a peculiar conical chamber ; but the only known 

 New Zealand larva is exceptional in the genus, 

 spun-up shoots like an ordinary Tortrix or Gelechia.
