scales ; the other fourteen joints nearly as in P. ambigua. The ending 

 of the radius is extremely close to the cross vein closing the basal cell. 

 Wing of a light colour, clouded with grey, and with four blackish hair- 

 spots — one at the radial fork a little beyond one on the posterior branch 

 of the pobrachial and the postical nervures, another at the end of the 

 axillar, and another (less distinct) at the end of the mediastinal nervure. 

 Wing, 1-75 to 2 mm. long 22. P. cowiors, sp. nov. 



7 — (36) Fork of the pobrachial nervure distinctly beyond both the radial fork and 



the end of the axillar nervure. Antennae in $ reach nearly to the middle 



of the wing ; the first two joints short, moderately stout, clothed with 



appressed scales, but with a few hairs spreading in front of the 1st joint ; 



1st oblong ; 2nd globular, contiguous with the next ; the other fourteen 



joints moniliform,with oblate-spheroidal nodules, mostly at rather wider 



intervals, and many with shallow, some with deeper, cupiliform verticils 



of hair. Wing grey, with blackish hairs towards the ends of the nervures 



and nine small black hair-spots in the disc ; wing's apex very near the 



end of the prsebrachial nervure. Wing, 2 mm. long 



23. P. labeculosa, sp. nov. 



„ a — Fork of the pobrachial nervure almost in line with the radial fork and the 

 end of tlie axillar nervure 8. 



8 — (7a) Wing pointed exactly at the end of the prsbrachial nervure. Antenna; in 



(? reach nearly to the middle of the wing ; the first two joints very 

 short, moderately stout, both of them globular and densely clothed with 

 slightly spreading scales, the other fourteen joints moniliform, with 

 nodules at moderate distances, and verticils, all but the last (which is 

 ovoid and closed) cupiliform, of very closely serried hair, containing each 

 a pair of spiral hair-like bristles, homologous with those of P. soleata. 

 Wing gi-ey, with a whitish patch of bristling hair at the base, followed 

 by a dark transverse band ; also with a whitish hair-spot at the end of 

 the axillar nervure, and an irregular whitish transverse fascia extending 

 from just beyond the end of the subcosta to the end of the anal nervure. 

 Wing, 28 nun. long 24. P. advena, s^. noy. 



a — Wing subobtuse between the praebrachial and cubital nervures. Antennse 

 in (J nearly as in P. amhigua, but with the basal joint about three times 

 longer than broad and the last two or three nodules rather nearer 

 together. Wing dark gi-ey, with a patch of whitish bristling hair at 

 the base, followed directly by three black hair-spots standing in line 

 transversely, viz., one at the radial fork, one on the posterior branch of 

 the pobrachial and on the postical nervures, and another at tlie end of 

 the axillar nervure. Wing, 2 to 27 mm. long . 25. P. morula, sp. nov.

1 Eadius meets the cubitus or is linked by a cross-vein to it at a distance 



from the anterior basal cell, less than the cell's apical width. Antenna; 

 16-jointed in both sexes, reaching in $ to the base of tlie wing ; the las( 



two uodulos distant from each other 2.
