This species was described from a specimen collected at Port 

 Stephens, N.S.W. It is not so common as the former species, 

 but specimens of it are to be found about Sydney in midsummer. 

 It differs from G. jndchellus in having the parallel markings on 

 the forewings much more defined and dai^ker, and only one black 

 irregularly rounded blotch near the tip of the hind wings. The 

 general colour is also much darker without any yellow markings. 

 In structure, size and form of wings there is very little difference, 

 except that the wings are a little more slender and pointed at the 

 tips. 



Glenurus erythrocephalus, Leach.

 1814. 



This distinctive lace-wing was also figured and briefly described 

 in Griffith's ' Animal Kingdom ' (Insects, ii. 1832, pi. 105, p. 327). 

 I have a specimen collected at Grafton, Richmond River, that 

 agrees with the wing-markings of this last figure; but Dr. David 

 Sharp, Curator of the Cambridge Museum, to whom a duplicate 

 specimen was forwarded, thinks it is a distinct species. I have 

 examined several in the Macleay Museum, and find that the 

 black spots and markings are very variable; in the hindwings of 

 one specimen the wing on one side bears five spots and its fellow 

 only three.
