636 AUSTRALIAN NEUROPTERA, i., 



into the hind margin. Tibiae with two spurs at the tip. Areolum 

 large and bifid. 



1, Media in both wings unforked Austronymphes. 



Media forked in the forewing, unforked in the hind wing 2. 



2. In the forewing, media forks as far out as the origin of 

 the radial sector, lietween first anal vein and the 



hind margin, two rows of celhiles Nympht-.s. 



In the forewing, the media forks much before origin of 

 first branch of radial sector. Between first anal 

 vein and the hind margin, one row of cellules Nesydrion. 



In Trans. Am. Ent. Soc, xxxix., p. 212 (1913), Mr. N. Banks 

 describes a genus, yymphydrion, including the species N. delicatum 

 Bks., from Queensland. I do not know whether this genus belongs 

 to the Nymphidfv or to the Myiodactylidcp.; probably it belongs 

 to the latter family. 



Austronymphes, gen. no v. 

 Labrum emarginate with rounded lateral margins and front mar- 

 gin. Maxillar}' palpi 5-jointed; 1st and 2nd joints short and of 

 equal length; 3rd as long as 1st and 2nd united; 4th two-thirds 

 as long as 3rd; 5th more slender, subcylindrical, as long as 3rd 

 and 4th united; the tip truncate. Labial palpi 3-jointed; 1st joint 

 short, 2nd joint twice as long as 1st; 3rd fusiform, as long as 1st 

 and 2nd united. No ocelli. Basal joint of antenna3 very stout; 

 2nd very short; 3rd twice as long as 2nd; 4th as long as 2nd and 

 3rd united; 4th and following joints longer than broad. Legs 

 rather slender; tibiae with two short and almost straight spurs; 

 tarsi shorter than tibiae. Jomts 1-4 diminish successi\ely by small 

 gradations ; 5th joint as long as 2nd, 3rd, and 4th united. 

 Puvilli large, subtriangular. Wings long and slender, rather 

 acute at tip; hindwings a little narrower and shorter than the 

 forewings. Costal area narrow; its cross veins simple, but forked 

 from the base of pterostigma. In the subcostal area one or two 

 basal crossveins, beyond thera a larger number are indicated by 

 short streaks arising from subcosta, but not reaching radius. 

 Siibcosta and radius united at the tip of the pterostigma. Radial 

 sector arises near base of radius; 8 branches from radial sector. 

 Media straight, unforked. Cubitus forks nearly opposite to
