continued between them along the frontal margin : face with a mem- 

 branous, semi-transparent, whitish triangular lobe standing out in front 

 between the antennae : antennae with two inflated basal joints, and a 

 long blackish inarticulate terminal seta ; the basal joint is concealed on 

 the inner side by a broad thin lobe-like production of the frontal sur- 

 face. Thorax stout, polished above, with raised lines and depressed 

 spaces. Legs whitish. Abdomen broad and depressed, the lateral 

 margins produced into teeth ; the colour in my example is dull greenish, 

 which proceeds from the eggs showing through the integuments, and a 

 mass of green eggs is protruded from the antepenultimate ventral seg- 

 ment ; in the cavity of the last segment beneath is seen a longitudinal 

 membranous lobe, produced into a rather long tooth. The three caiidal 

 setae nearly equal, white, not so long as the abdomen, stout and glabrous 

 at the base, all pubescent at the tips. Wings whitish, semi-opaque, 

 with a slight smoky-grey tinge : the anterior pair long, triangular, with 

 three strong longitudinal greyish veins (without counting the costa), 

 the second and third of which are furcate from about the middle, all 

 starting from the base ; seven or eight transverse wavy veinlets between 

 the first and second veins : posterior pair ovate, more transparent, veins 

 white. 



One female imago (?) of this fine species was taken by Mr. Trimen at 

 light, at the Mapumulo Mission Station, Umroti District, Natal, on the 

 evening of the 3rd March, 1867.

Alar expanse 7 to 8 lines ; head, face, thorax, body and legs 

 light, creamy, ashy-grey, — lightest towards the cleft ; very slightly 

 irrorated with darker atoms ; the discoidal and cleft-spots scarcely 

 perceptible. Under- wings rather darker than the upper- wings. 



Ft. Eodgkinsonii differs from JPt. Lowei, to which it is nearly 

 allied, in the general colour being lighter, the less irrorated or suffused 

 appearance, its lesser size, and in its want of the light canary-coloured 

 terminal costal edging to the tip ; and also in its time of appearance ; — 

 from Pf. plagiodactylus in its smaller size, much lighter colour, the 

 entire want of the bright buff and light ashy- white upon the thorax and 

 body, the absence of the dark blotches so conspicuous upon good speci-
