ab. obsoleta (Tutt.Brit.Butts.1896.p.161.)

ab. caeca (Courvoisier.Z.Wiss.Ins.Biol.1907.3.p.75.)

= extrema Tutt.Brit.Lep.1908.X.p.108.

On the underside all spots except the discoidals are absent. Courvoisier says the discoidal spots may also be absent.

ab. alcetoides (Tutt.Brit.Lep.1908.X.p.108.)

On the underside of the forewings the last two submedian spots, those near the inner margin, are placed out of line with the rest, making it bent.

ab. atriata (Tutt.Brit.Lep.1908.X.p.110.pl.4.f.8.)

= elongata Courvoisier.Ent.Z.1910.24.p.210.
= elongata Kiefer.Z.Ost.Ent.Ver.1938.23.p.67.
= striata Baynes.Entom.1941.74.p.100.

On the underside of the hindwings the spots are elongated into small dashes. The figure shows the forewings almost obsolete, the hindwings with a series of three marginal streaks, the longest nearest the anal angle. There is also a black costal spot towards the base. Courvoisier's elongata was named from Tutt's figure. Kiefer's description agrees almost exactly with Tutt's figure. Baynes figure shows three streaks on one wing and two on the other so is not so extreme, Tutt's figure showing three streaks and a spot on each wing.

Large specimens over 24mm.

ab. minor (Tutt.Brit.Lep.1908.X.p.107.)

= minutissima Stephan.Iris.1923.37.p.45.

Small specimens under 19mm. Stephan's minutissima can be separated if so desired because it was less than 14mm but covered by Tutt's minor.

ab. minutus (Esper.Eur.Schmett.Suppl.1787.pt.1.p.71.pl.CVI.fig.8.)

The figure is apparently of a small minimus but the fringes of the forewings are chequered. If this is correct it is a most unusual form and cannot be treated merely as a dwarf.
