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. 

 Drejjanoptenjx humilis, M'Laclil. Joiirn. of Entoni. vol. ii. p. 116, pi. vi. 



fig. 5.* 

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

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



Genus MiCROMUS, Kambur. 

 24. Micromus tasmanice^ Walker. 



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

 p. 186.* 



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 Ilemerohius as restricted.

Genus Q^x'ONESUS, M'Lachlan. 



25. (Econesus maori^ M'Lachlan. 

 (Econesits maori, M'Laclil. Trans. Ent. Soc. Lond. ser. 3, vol. i. p. 303 * ; 

 id. Jouru. Linn. Soc, Zool. vol. x. p. 211, pi. ii. fig. 1 (neuration), c? . 



I now possess the female of this insect ; it differs from the 

 male in its larger size ; the neuration of tlie 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.
