124 [May, 1893. 



radius forked distinctly before the end of the axillar nerrure ; pobrachial 

 forked almost opposite the said end, a little before the middle of the 

 wing. Antennae short, hardly reaching to the base of the wing ; in df , 

 15-jointed, thickened considerably with scales on the first three joints, 

 and beset with spreading verticillate hairs on the other twelve joints ; 

 1st joint elongate, subclaviforra, slightly compressed ; 2nd joint stout, 

 subglobular ; 3rd joint less stout, oval, furnished anteriorly near the tip 

 with a peculiar looped appendage (which is clad with scales) lying along- 

 side of the next two joints with its end outwards ; when denuded and 

 highly magnified this appendage is resolvable into a ribbon-like fascicle 

 of long and seemingly agglutinated testaceous hairs ; the succeeding 

 joints for the most part moniliform, with fusiform-ovoid nodules at short 

 intervals. Antennae in 5 16-jointed ; the first three joints somewhat as 

 in the $ , but shorter, and without an appendage to the 3rd joint, which 

 is narrower in this sex ; the other thirteen joints, mostly ovoid and near 



together, beset with spreading verticillate hairs 2. 



a — Wing either pointed at, or very near, the end of the prsebrachial nervure, 

 or else subobtuse between this and the end of the cubitus ; fringe dark, 

 sometimes with a whitish gloss in the neighbourhood of the wing's apex ; 

 anterior basal cell short, or of unexceptional proportions. Antennae in 

 both sexes 16-jointed ; 1st and 2nd joints clad with dispersed scales and 



hairs; the other fourteen joints with verticillate hairs 3. 



2 — (1) Anterior basal cell almost one-third the extreme length of the wing, met by 

 the radius at a distance equal to three times the cell's apical width from 

 its end ; stem of the pobrachial fork shorter than the difference in length 

 of the two basal cells, and not quite two-thirds the length of the stem of 

 the radius. Legs black and white ; some white scales at the tips of the 

 tibiae and of the first three tarsal joints ; a whitish gloss on the tarsus 

 dorsally from near the tip of the 1st joint to the tip of the 3rd or (from 

 certain standpoints only) 4th joint. Wings black-brown, with whitish 

 markings ; a dark basal patch or fascia, saliently angulated at the anterior 

 basal cell; a moderately broad, transverse, angulated, whitish fascia 

 before the forks, which does not enter the posterior fringe ; dark markings 

 corresponding with the median fascia and apical space in P. trifasciata, 

 confluent extensively along the cubitus, praebi'achial and the pobrachial 

 fork ; whitish markings representing a broken and somewhat zig-zag 

 further fascia expanded moderately at the ends, tending to produce an 

 ocellated spot at the posterior margin and fringe that is pupillated at and 

 near the end of the postical nervure, and another less distinctly marked 

 out on the costa, not entering the fringe, opposite the former and im- 

 perfectly pupilated towards the end of the anterior branch of the radius. 

 Wing-margin dark, varied with white tufts of declinate hair at the ends 

 of the subcosta, radial and pobrachial branches, postical and anal ner- 

 vures, fringe dark, glossed with a light colour from about the end of the 

 cubitus to the posterior branch of the pobrachial, and again from about 

 the end of the postical to just beyond the end of the anal. Basal joint 

 in the superior $ appendages stout, oblong ; 2nd joint about one and a
