776 STUDIES IN AUSTRALIAN NEUROPTERA, VI., 



where a number have been taken at electric lights. I know of 

 no record furtlier north than this. 



PsYCHOPSis GRACILIS, n.sp. (Plate Ixxviii., fig. 10). 



(J Total length, 11 mm.; abdomen, 5-5mm.; /oi'ewhig, 20 5mni : 

 hiadwing, 17*5 mm.: expanse, 42-5 mm. 



Head pale brownish in colour, 1*8 nnn. wide, eyes black, 

 antenme pale ochreous, 4 mm. long. 



T h o r a X : prothorax pale ochreous, 06 mm. long by 1*2 unn. 

 wide. Pterothorax pale ochreous anteriorly, shading to dark 

 greyish-brown behind, irregularly marked with brown blotches: 

 greatest width 2 mm. Legs very short, very pale ochreous in 

 colour, slightly darker on tibiae and tarsi. 



Wings with a general resemblance to those of Ps miinica, 

 but much more transparent, more delicately built, and less hairy. 

 If placed upon a dark background, the wings of Ps. mhnica 

 appear white, with their pattern of dark fasciae and other mark- 

 ings showing up very distinctly; those of Ps. gracilis, on the 

 other hand, are very transparent, so that neither tlie venation 

 nor the colour-pattern shows up well under these conditions. 

 Forewings more triangular in shape than those of Ps. miinica, 

 more narrowed towards the base, and slightly wider at the level 

 of the tornus. Only four distinct transverse fasciae, of which the 

 first two are only lightly indicated in the costal area (those of 

 Ps. mimica are most strongly marked in this area); the most 

 basal fascia runs as a slight arc from Sc to the dorsum, at about 

 one-fourth of the wing-length from the base; the second is incom- 

 plete, and passes from Sc transversely only half-way across the 

 disc, a little basad of the middle of the wing; the third is well 

 marked on the costal area, slightly broken as it approaches Sc, 

 then well marked as it passes downwards, somewhat obliquely, 

 to meet the fourth above the tornus; the fourth fascia is also 

 well marked in the costal area, and passes just outside the 

 anastomosis, transversely downwards, to meet the third at an 

 angle of about 50°. On this fourth fascia, just before it meets 

 the third, are two distinct blackish spots; below the union of the 

 fascia, and extending to the tornus, is a broad pinkish band,
