242 BOTTDID^.— PTEROPHOEIDiE. 



THYSANOIDMA, g. ii. 



Allied to Homophyca. Male with outer margin of fore wing more evenly rounded, of 

 hind wing more excised below the apes. Hind legs very long. The cilia on outer and inner 

 margins of hind wing swollen into knobs at the extremities, and irregular in length. 



Thysanoidma octalis. (Plate CLVI. fig. 19.) 



Expanse /^ incli' 



Male. Fore wing smoky black ; an ochreous patch on centre of costa, from the basal end 

 of which a pale black-margined narrow curved band runs to middle of inner margin of hind 

 wing ; a similar postmedial band from costa before apex curving round and joining the ante- 

 medial band at end of cell, then outwards and again inwards to lower extremity of cell of 

 hind wing, thus forming with the antemedial band a nearly complete figure of eight ; apical 

 area ochreous, becoming white at apex. Hind wing orange-yellow, smoky black within ante- 

 medial band ; a conspicuous black spot at end of cell. Cilia ochreous white. Underside 

 paler. 



PTEROPHOEID^. 



KOREMAGUIA, g. n. 



Antennae rather stout, tlic basal joints scaled ; palpi porrcct, of moderate length, the 

 basal joint scaled, terminal joint a denuded spike; fore leg with long hairs along the hinder 

 side of the tibia, and with two spines at the distal end ; hind pair of legs with two spines at 

 the distal end of tibia ; liind legs rather thick and of moderate length ; two large tufts of hairs 

 on the upper and lateral surfaces of tibia — one at middle, the other at distal end, each with a 

 pair of long stout spines just beyond them. Primaries shaped as in Platyptilus ; secondaries 

 with the feathers not expanding towards their extremities, and with no spatulate cilia on the 

 inner margin. 



Koremaguia aurantidactyliis. (Plate CLVI. fig. 20.) 



Expanse | inch. 



Male. Bright golden fulvous. Primaries black at extremities, with a white submarginal 

 line and traces of a pale cilial line. Antennae black, the basal joints clothed with golden 

 fulvous scales. Hind legs with the spines and terminal joints of tarsus white. 



Captured hovering at a flower, 10 feet from the ground, in bright sunlight.
