way between the first and the end of the cell ; here the subcostal 

 divides and forms an oval additional cell, devoid of scales, from the 

 upper end of which the third and fourth subcostal branches start, 

 and the fifth from the lower end ; discocellular regularly curved ; 

 the radial from the centre ; upper median from a little above the 

 lower end of the cell ; middle median from its end ; lower at four 

 fifths ; submedian straight to a little above the anal angle ; iuterno- 

 median fold parallel to it ; internal vein curved liasewards. Hind 

 wings triangular, but with both angles rounded ; the subcostal much 

 thickened at the base, having apjjarently absorbed the costal ; the 

 cell broad, reaching to four fifths of the wing ; discocellular strongly 

 angulated basewards in the centre, its upper lialf obsolete ; two sub- 

 costal branches from the upper end, from the upper one of which a 

 shord third branch is emitted, representing the end of the costal ; a 

 recurrent vein through the angle of the discocellular ; radial and two 

 upper medians all close together from the lower end of the cell ; 

 lower median at four fifths ; three internal veins. Head, thorax, 

 and abdomen stout, as are the legs and palpi ; the latter thickly 

 scaled, as long as the head, ascending, the third joint curved down- 

 wards ; antennae laminated, very thick in the male ; eyes large. 



79. Thyridiphora. fenestrata, sp. n 



Fore wing greyish ochreous with two faintly darker lines, which 

 show slight traces of serration ; one leaving the inner margin in the 

 middle and curving into the costa, the other starting a little way 

 beyond the first and running obliquely towards the apex, but deflexed 

 before reaching it on to the costa, which it reaches above the oval, 

 scaleless eyelet-hole, which stands beyond the apex of the cell ; 

 fringes slightly darker. Hind wing paler, but with darker hind 

 margin. Underside dull ochreous, with patches of darker scales 

 along the course of the lines. Head, thorax, aud abdomen all pale 

 ochreous. Expanse of wings 14 millim. 



One female, Campbellpore, July 3, 1886. 



This peculiar little species is like a Bombyx mori in miniature. 

 It appears much subject to grease. Two examples from Col. 

 Swinhoe, unnamed, in the Brit. Mus. collection, are almost trans- 

 parent from this cause. Although so much smaller in expanse, the 

 neuration of the wings and the structure of the antennae indicate an 

 affinity with the Thyrididae.

One male and one female from Campbellpore, taken early in June, 

 1886. 



The only difference discernible in P. extrahens, Wlk., = P. signi- 

 ficans, WlL, is that the males have the underside of the anal tuft 

 blackish.
