Antenne dark blackish-fuscous. Head blackish, clothed with 
golden-yellow hairs. Palpi yellow. Mesothorax black. An- 
terior wings blackish, with numerous golden-yellow spots, some of 
which are larger than the others; apical cilia blackish, inter- 
rupted with yellow. Posterior wings grey; fringes dark grey, 
those of the apical portion of the costa darker than the rest. Legs 
greyish or brownish-ochreous. Abdomen greyish-black. 
Expanse of fore-wings 35 —44 lines. 
Occurs in summer and autumn about both standing and running 
waters, but preferring the latter. Found in various parts of the 
country, probably nowhere abundant and frequently overlooked. 
TI examined Curtis’ types, and could detect no differences in 
his two species that I could consider specific. It is liable to con- 
siderable variation in the number and size of the golden spots on 
the anterior wings; I possess an example, in perfect condition, in 
which these spots are altogether wanting, the wings being uni- 
formly black ; this was taken in company with the ordinary form. 
Probably there may be sexual variations in the adornment, but 
at present we know too little of the species to speak with cer- 
tainty on this point. The anal appendages are very minute and 
highly complicated. 
Genus Hyproptiza, Dalman. 
Antenne stout. Head densely hairy. Ocelli absent. Maxil- 
Jary palpi four-jointed in the males. Labial palpi with the ter- 
minal joint thickened and cylindrical. Anterior wings densely 
clothed with long shaggy hair, and with long fringes ; very narrow, 
acutely pointed; neuration very strong, appearing as if dotted 
under the microscope (these dots are perhaps the tubercles 
whence spring the hairs), probably varying in the sexes or in the 
different species. Posterior wings very narrow; fringes very 
long; apex very acute; costal margin strongly excised from before 
the middle up to the apex; one transverse vein. Legs rather 
short; anterior tibiz without spurs; intermediate tibize with one
