I have two examples which scarcely appear to differ specifically from 
others from Australia; but it is desirable that long series of both Australian 
and New Zealand specimens should be compared. The insect has the costal 
area of the fore wings narrowed at the base, and without a recurrent nervule, 
and hence is a Micromus and not a Hemerobius as restricted.

I now possess the female of this insect; it differs from the male in its 
larger size ; the neuration of the anterior wings is regular ; and in the posterior 
wings there are two additional apical forks. The maxillary palpi are 5-jointed, 
the basal joint very short, the second slightly longer, the third to fifth still 
longer and nearly equal inter se.

HELICOPSYCHE. 
This term was applied to certain cases of the larvæ of Trichoptera found in 
Europe, which depart from the usual forms and assume a spiral condition, thus 
resembling small Helices, formed of sand grains neatly cemented together ; 
and this resemblance has often deceived conchologists, who have described 
them as shells. They have since been found in streams almost all over the 
world, and their real nature has long been known. Recently in North 
. America the perfect insect of one species has been bred. Three forms occur in 
New Zealand (çZ M‘Lachlan, Journ. Linn. Soc., Zool. vol. x. p. 200) There 
is yet much mystery about the species that form them ; and it is possible that
