triangles very small. Hindwing very broad at base, narrowing 

 rapidly to tip. Inner angle of triangle of hind wings at level of 

 arculus. One cross-nervule (and hence no subtriangle), in sub- 

 median space of hind wings. One discontinuous postnodal in 

 fore wings, two in hind wings. Discoidal area of fore wings 

 narrowed at tip of wing. 



Cordulephya Selys (C. iiygmcea Selys, type). 



Triangle of forewings with the upper side broken, forming a 

 quadrilateral, the proximal segment twice or thrice as long as the 

 distal. All triangles very small. Hindwing very narrow. 

 Inner angle of triangle of hindwings well beyond level of arculus. 

 Two cross-nervules (and hence a small simple subtriangle) in 

 submedian space of hindwings. Only one discontinuous postnodal 

 in all wings. Discoidal area of forewings same as in Neophya. 



Austrophya, n.g. (A. mystica, n.sp., type). 



Triangle of forewings with the upper side broken, forming a 

 quadrilateral, the proximal segment twice as long as the distal. 

 Triangles twice as large as in the other two genera, that of hind- 

 wing very wide. Hindwing very broad from base to near tip. 

 Inner angle of triangle of hindwings only just beyond (0 - 2 mm.) 

 level of arculus. Cross-nervules as in Cordidephya, but second 

 placed under the arculus and not beyond it. Two discontinuous 

 postnodals in all wings. Discoidal area of forewings widened at 

 tip of wing. 



1. Austrophya mystica, n.sp. (Plate xxi., tig.l). 



(J. Unknown. 



£. Unique. Total length 37 mm.; abdomen 29 mm,; forewing 

 26 mm., hindwing 25 mm. 



Wings: neuration thin, black; base of forewing saffroned 

 deeply for 6 mm. along subcostal space, and also throughout the 

 submedian space; base of hindwing less saffroned, deeply for 

 2 mm. only along subcostal space. Pterostiyma 1*4 mm., black, 

 only moderately broad. Membranule very small, greyish-brown.
