more forms await discovery. The family being one of exceptional interest, 
Our 
present knowledge points to the Hepaticae (liverworts) as being the food- 
plants of the larvae, and the imagines should be looked for near these 
plants; sweeping the low herbage in the vicinity is the most likely 
method of making captures. 
At present the New Zealand Micropterygidae are placed in two genera— 
j ruela Walk.; and Micr rdalis 
Meyrick, 1912, type doroxena Meyr.* The former genus contains thirteen 
of the species, the latter being monotypic. On the venation alone, how- 
ever, Micropardalis can hardly be sustained, Meyrick, who had but a single 
specimen, having fallen into error regarding the most important character, 
the condition of В, in the hindwing. Possibly, when the other structural 
characters are taken into consideration, the genus may prove a valid one, 
in which case systematic value may be placed on the point of origin of 
R,-; in the forewing, which in doroxena alone is sessile on the cell. ; 
i the whole of the species 
be divided into three 
the condition of R, in the 
Captured by Sc, . In two of the species, S. lucilia Clar 
Meyr., the free basal portion of Ri is present unaltered (fig. 1); in two 
d S. zonodoza Meyr., all trace of the free part 
*ld i Mnesarchaea Meyr., as I think that Tillyard (Proc. 
E MAS molde M ЖАЫ, 1910) has shown sufficient reason to justify its 
removal from thé family.
