T. vigil Prout (1 g), founded on a from Upper Burma, occurs also at Tsekou. The forewing is some- vigil. 
what like that of davidaria but without the heavy brown cloudings; hindwing with postmedian anteriorly 
more as in euclidiaria, but its white (not dark-grey) abdominal area is very distinctive. 
T. euclidiaria Oberth. (Vol. 12, pi. 8h). Similar to leopardinata (Vol. 12, p. 57) but differing in the reduc- euclidiaria.

S. lucida Warr. This species, and therefore the genus of which it is the sole exponent, is only yet known lucida.

Ps. pruinata Hufn. — ab. pallida Rocci (= candidata Slander) (1 h) is white, hardly tinged with green- ■pallida. 
ish, the dark lines wanting, as in ab. agrestaria. Rocci described it from Piedmont; Stauder took 2 fresh $$ 
at Triest, where the prevailing form is said to be agrestaria. — ab. albescens Schwingenschuss is also white, albescens. 
but retains the lines, which are brown. —- ab. grisescens Reutti (1898), redescribed as new under the same name yrisescens. 
by Hannemann in 1917, is a grey form closely similar to coronillaria. Its incidence has not been thoroughly 
worked out and it is possible it may have considerable geographical importance. —- Of the ab. fasciata Prout fusciata. 
(Vol. 4, p. 14) we now figure (pi. 2a) a very typical example from the Senckenberg Museum. — nigrolineata nigrolinea- 
Schwingenschuss , founded on Brunswick material, is said to be, in its black lines, characteristic of nearly the 
whole series, whether green or grey-green. As this darkening of the lines is also characteristic of the Atlantic 
Region of N. W. Europe, Heydemann adopts this name for that race in preference to — holsatica. F. Wagn. holsatica. 
(6 c), an extreme development of nigrolineata in S. Holstein and Hanover, light or darker grey, culminating 
in blue-grey; underside, especially of the forewing, grey-brown to blackish. —- ab. albolineata F. Wagn. is an albolineata. 
aberration of holsatica, with the subterminal line very sharply white. — On the islands of Amrum and Sylt, 
the form holsatica is unknown and even nigrolineata very rare; the weakly-marked forms, like agrestaria Dup., 
predominate and develop in over 20 per cent a pretty, unicolorous grass-green form, ab. loc. viridisquama viridisqua-

marked, postmedian line intense and more deeply dentate than in the type, subterminal also rather strongly 
dentate. North Africa, described as a race; although the size there varies as strongly as in Europe (forewing 
13—-19 mm) and the ground-colour from whitish to decidedly dark grey, I have accepted the designation for the 
forms from N. and E. Algeria and Tunis. —- lesuraria D. Luc. “S 30 mm, $ 36 mm.” Near f. armoraciaria, lesuraria. 
both wings above almost unicolorous, irrorated with very pale greyish brown; subterminal little marked; post- 
median distinct and angular ( ? dentate), as also the antemedian of the forewing. Said to be constant in 
the Sefrou district, Morocco.

to the Palaearctic rather than to the Indo-Australian fauna. We figure the type specimen. 
9. Genus: Agathia Guen. 
(see Vol. 4, p. 14; Vol. 12, p. 68 and Vol. 16, p. 12.) 
A. lycaenaria Roll. The type of this species was not, as stated in Vol. 4, p. 15, pi. 1 h, from “Kashmir”; lycaenaria. 
with the exception of one species, which was not exactly localised, all the Geometrids collected by von Hegel 
on his expedition are definitely stated to have come from Masuri. lycaenaria (on which see Vol. 12, p. 67) 
is evidently not truly Palaearctic and the only record for West China which I can trace is the one specimen 
from Huang-mu-Chang (N. W. of Wa-shan) cited by Leech, a $ with the markings rather slender for that sex 
(possibly racial). 
A. hllarata Guen. (Vol. 12, pi. 9 d). Type locality doubtful. The species which appears to agree with hilarata. 
Guenee's type (see Vol. 12, p. 70) reaches N. W. India and is a little smaller than most of the similar Agathia,
