base, gradually tapering towards pterostigraa. All four wings 

 strongly curved towards tips, which end in a slight point; 

 the posterior margin being very slightly hollowed out towards 

 the tip, the wings have a slightly falcate appearance. 

 Colouration : forewing richly mottled with black and white, 

 the former colour due to pigment, the latter to a very close 

 arrangement of numerous, parallel, white veins. Costal 

 space irregularly blotched with black patches, separated by 

 hyaline spaces crossed by white veins. In the pterostigmatic 

 region, and extending nearly to tip of wing, is a large, subtri- 

 angular, white patch, the curved wing-border forming its base, 

 while its apex is directed pusteriad and forms an angle a little 

 greater than a right-angle. On this patch, two small black spots 

 interrupt the white wing-border. The rest of the wing is very 

 irregularly and heavily marked with black. Hindwing nearly 

 all hyaline in its basal half; then follows a large, irregular, black 

 blotch right across the wing before the level of the pterostigma, 

 but somewhat interrupted between M and Cu distally; beyond 

 this, covering the pterostigma and all the apical part of the wing 

 except the extreme tip, is a whitish patch, larger and more 

 irregular than the corresponding patch in the forewing. [In 

 the dead insect, the black wing-pigment fades gradually to a 

 dark, semi-transparent brownish, as in Poristmis strigatus\.

 rare. Mr. E. J. Dumigan captured, in January, 1914, four 

 specimens sitting on the large rocks of the river-bed.

 Of the remaining three, one has been placed in Mr. Esben 

 Petersen's collection, another in that of Mr Nathan Banks, and 

 the third remains in my collection.

This sul)fainily was formed by N. Banks to include all those 

 genera in which there is only a single cross-vein in the radial 

 space of die hindwing, before the origin of the radial sector. As
