lengthwise, are probably a generical feature ; on each margin the two nearest to the base 

 are slightly larger than the others. Legs brownish black with white markings : — a white 

 gloss at the knee ; a whitish gleam down the upper half of the tibia, and a white scale- 

 spot on the exposed side of its tip ; also a narrow oblique annulation, broadened on one 

 side in the hind foot, at the apex of the 1st joint in the tarsus. The tibial bristles take 

 a white gloss. Indumentum of the head and thorax in $ generally concolorous with the 

 predominant tint of the wings ; in $, parts take a white gloss, e.g. the sepia-black-brown 

 palpi, the frontal scales and scales on the inner side of the basal joints of the antennse ; 

 indumentum of the pronotum and in front of the wing-roots is also liable to a light gloss. 

 Abdomen (in contrast with the scutellum and metanotum) smooth haired ; the hairs long 

 and silky, of the prevailing dark hue. Superior genital appendages in $ similar (viewed 

 broad-side) to the upper part of a bird's head : protopodite longer than broad, rounded 

 externally ; exopodite produced obliquely along the articulation, falcate or subulate with 

 decurved tip garnished with two minute, erect, preapical setulse ; endopodite wanting, 

 unless present in the guise of an upper penis-cover composed of two strong oblique- 

 pointed, acviminate spines, grooved longitudinally within, and extended laterally at the 

 base, flanking a pair of short compressed subulate blades produced from the termination 

 of the ductus ejaculatorius, subtended by a short, subacute, triangular lobe, (?) lower 

 penis cover, that is not to be confounded with the obtusely sub-triangular terminal lobe 

 projecting to the rear beyond the insertions of the inferior genital appendages. 



Wings of ? ovate lanceolate : R^ branching from R'^ midway between the axil of the 

 sectorial fork and the fold of deflection ; marginal area (subtended by /?') narrower than 

 the maximum breadth of the space between Cu" and the inner margin. 



Loc. Seychelles. Mahe : Cascade Estate, about 800 feet, many examples, from 

 windows of house, &c.; near Morne Blanc, about 800 feet. Silhouette: plateau of Mare 

 aux Cochons, over 1000 feet, IX. 1908, 1 specimen. Also known from India; Matheran, 

 W. Ghauts, Bombay, 800 m. (Biro, 8. VII. 1902: ex Mus. Nat. Hung., Budapest, by 

 favour of Dr Kertesz). Prep., Eaton, no. 44, a — -f. 



Panimerus, gen. nov. (PI. 26, fig. 4). 



Wings obovate — lanceolate, acute at R'', the costa arcuate in a less degree than the 

 opposite margin, and the endings of veins posterior to the apex rather wider apart than 

 those of the radius and its branches in most cases : anterior basal cell extended beyond 

 the fold of deflection ; pedicel of the sectorial fork weakly attached to this cell, usually 

 at some point interior to the ci'oss-vein R to M, seldom subopposite thereto in individual 

 flies (c/. P. hirtus ; Prep. Eaton, no. 47, d and k) : sectorial fork longer than the median, 

 and extending inwards deeper than the middle of the wing, except in the Algerian 

 species P. nadorensis, sp. nov. (Prep. Eaton, no. 51 a) which has these forks of almost 

 equal length, reaching to about the wing's middle ; cubital fork sessile ; cross-veins some- 

 what vague ; R sometimes shortly prolonged into the basal cell. Wing-membrane nude ; 

 the nervures beneath, to a distance from the roots diflering with the species, clad in 

 $ flies with narrow-linear or linear-lanceolate distichous scales narrowed basally to a short
