Hah. — Hornsby and Ourimbah, N.S.W. ; Mount Tambourine, 

 S. Queensland; rare. February to April. Probably it would be 

 found all up the Eastern Coast, if searched for. Its late appear- 

 ance in the season is in marked contrast with the habit of >S'. 

 icei/ersi, which can be found at the end of October, and seldom 

 lasts until the end of January. Thus, even if the two species 

 were to be found in the same locality, there would be practically 

 no chance of their intercrossing. 



8. Sv'NLESTEs TROPICUS, n.sp. (Text-figs.8(^, 9). 



This species differs from S. selysi in its excessively slender 

 build, its very narrow wings, very short 

 black pterostigma (Text-fig. 8c/), and in the 

 different form of the superior appendages, 

 which are slenderer, and lack the large inner 

 tooth on the apical half (Text-fig. 9). Abdo- 

 men 51 mm. long, width at segs. o-6 only 

 0'4 mm. FovPiriny 29 mm. long, greatest 

 width only 4 mm. Pfprostiyma of forewing 

 1 mm. long, covering only a little more than 

 one cellule: jet black. 9. Not known. Text-fig. 9.*

 9. Argiolestes chrysoides Tillyard. (Text-fig. 10, a, c). 

 This species was originally de.scribed by me from a single male 

 taken by Dr. A. J. Turner, at Montville, Blackall Ranges, Queens- 

 land. In October, 1915, I visited the Blackall Ranges, staying 

 at Malen}^, some twelve miles south of Montville. The district
