128 [June, 



„ a — Radius and cubitus confluent at a distance from the anterior basal cell equal 

 to or greater than the cell's apical width. Antennae in S 15-jointed, or 

 apparently so ; the 16th joint, when present, in close contact with the 

 15th 3. 



2 — (1) Radius forked considerably before the pobraohial fork, which fork is oppo- 

 site the end of the axillar uervure. First two joints in the $ antennae 

 short, with slightly spreading hair and scales, the 1st obovoid, the 2nd 

 globular ; the other fourteen moniliform, with globular, shortly pubescent 

 nodules at moderate intervals, and rather wide cupilifoi'm verticils of 

 hair. Wing dark grey or brownish-grey, with an irregular, narrow, 

 blackish, transverse fascia, extending from the end of the axillar nervure 

 to the anterior branch of the radius, containing two black hair-spots 

 (one on the branches of the radius, and the other on the posterior branch 

 of the pobrachial and the postical nervure), and preceded by a third 

 hair-spot just beyond the middle of the axillar nervure ; at the fork of 

 the radius, opposite this last spot, is one less distinct ; at the ends of the 

 nervures by the posterior miirgin are declinate black hairs. Wing, 2.25 

 to 3 mm. long 26. P.fratercula, sp. nov. 



„ a — Radius forked very little before or subopposite the pobrachial fork, and 

 very little beyond or subopposite the end of the axillar nervure ; po- 

 brachial fork just out of line with them. Antennae in <J as in P. 

 fratercula. Wing dark brownish-grey, with seventeen small black hair- 

 spots arranged in five transverse rows ; fringes chequered with fawn 

 colour (cervinous) and greyish-black in nine places. Length, 2 to 3 mm. 

 27. P. ustulata (Haliday MS.), Walker. 



3 — (la) Radius forked very little beyond the pobrachial fork, subopposite the end 

 of the axillar nervure, and confluent with the cubitus about as far from 

 the anterior basal cell as the cell's maximum width Antennae in $ 

 actually 16-jointed, reaching to the base of the wing ; first two joints 

 densely clothed with scales that spread inwards and upwards, the 1st 

 oblong, somewhat compressed, thrice as long as broad ; 2nd joint oval ; 

 the other joints moniliform with globular nodules and cupuliform verticils 

 of hair. Wing blackish, with fringes to match (these glossed with 

 brownish), and two obliquely transverse darker interrupted fasciae or 

 series of hair-spots- -one across the forks from the end of the axillar 

 nervure, the otlier, at the end of the region of bristling hair, extending 

 from the end of the postical nervure to the anterior branch of the radius ; 

 in the apical region are blackish decumbent hairs towards the ends of 

 the nervures. Wing, ? , 2'25 to 2'5 mm. ; J , less .. 



28. P. caliginosa, sp. nov. 



„ a — Radius forked shortly beyond the pobrachial opposite the interval between 

 the ends of the axillar and anal nervures, and confluent with the cubitus 

 rather farther from the anterior basal cell than the cell's apical width ; 

 pobrachial fork nearly in line with the radial fork and the end of the 

 axillar nervure. Antennae in $ 15-jointed, reaching to the base of the 

 wing : first two joints clothed with appressed scales, short, the Ist
