DIAGNOSES OF NEW AND ILL-DEFINED SPECIES. 
Sciophila plurisetosa, sp. n.—Wing-length, 3 mm. Head black ; 
palpi and first five or six antennal joints yellow; mesonotum 
ochreous brown, with traces of two darker lines; pleurze darker ; 
postnotum and abdomen blackish; pubescence of body all 
yellowish ; legs yellow, except for the tarsi; tibial spurs yellow, 
the short spines black; wings as in S. Airta, Mg.; hypopygium 
much as in S. #irfa, Mg., but ninth tergite with an apical row of 
six distinctly differentiated bristles; claspers with about six strong 
short bristles round the tip, in addition to the four long ones 
which point inwards (thus resembling S. tzferrupta, Winn., to 
some extent). Type, male, in the British Museum, from Catacol, 
Arran, ( Waterston). 
Trichonta albescens, Dziedzickii—The hypopygium has been 
figured by Dziedzicki (Pub. Soc. Sci. Varsovie, III. Classe Sci. 
Math. et Nat., 1915: ‘“‘Atlas des organes génitaux (hypopygium) 
des types de Winnertz, et des genres de sa collection de Mycéto- 
philes,” Figs. 144-145), but the species is otherwise undescribed. 
In the Brodick male the antennee are nearly twice the length of 
the thorax, the first three joints yellowish; thorax dark grey, with 
pale yellowish vestiture, shoulders indistinctly yellow; abdomen 
blackish, the hind margins of the tergites indistinctly yellowish ; 
coxe and femora yellowish; hind coxz with two small bristles 
near the base; wings clear. As in many of his figures, Dziedzicki 
seems to have slightly exaggerated the thickness of the stronger
