variety indicated at fig. 4*, with a large whitish costal spot in 

 the fore wings ; but at present I see nothing to indicate that 

 these form a distinct species. 



23. Drepanopteryx humilis, M'Lachlan.

Found also at Moreton Bay. . The smaller size seems to in- 

 dicate that this is not a form of D. instabilis. 



Genus Micromus, Rambur. 



24. Micromus tasmanice, Walker. 



Hemerobius tasmanice, Walk. Trans. Ent. Soc. Lond. ser. 2, vol. v.

I have two examples which scarcely appear to differ speci- 

 fically 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. 



Tkichoptera. 

 Sericostomatidae. 



Genus (Econesus, M'Lachlan. 



25. (Econesus maori : M'Lachlan.

 id. Journ. Linn. Soc, Zool. vol. x. p. 211, pi. ii. fig. 1 (neuration), J . 



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.
