Mzvnick.—On New Zealand Micro-Lepidoptera. 11 
with 19 veins, 8 and 9 stalked, 11 coalescing with 12 before costa. Hind- 
wings with 8 veins, 5 from above angle of cell, 6 moderately approximated 
to 7, 7 and 8 stalked, cell closed. 
A very distinctly characterized genus, of the general type of Thinasotia, 
but with vein 11 of the forewings running into 12 before reaching costa, 
vein 5 of the hindwings rising from the transverse vein above the angle of 
cell, and the hindmargin of forewings twice indented above middle. The 
venation of all the New Zealand species is perfectly constant. Three 
species have been described from South America, and one from Australia ; 
nine are here given, so that the genus apparently reaches its maximum of 
development in New Zealand. The species are all rather small insects, 
with broadly triangular forewings, generally rather elegantly marked, the 
markings consisting typically of two slender transverse lines, a white or 
metallic discal spot, and generally three black spots on lower part of hind 
margin. The larva feeds in moss. The imagos are often overlooked, and 
probably many more will be discovered.
