indistinct, either partially or completely absent. Orbicular stigma barely discernible, reniform stigma faintly 
outlined, with paler streak in centre. — turbata Kard. is monotonous pale grey-brown with diffuse markings, 
indistinct lines and stigmata. All 3 forms from S. Ussuri, in July. 
P. lunulata Stertz is very similar to flavomacula mentioned above, but. it is a brighter brown in marginal 
area of forewings. The outer transverse line commences in centre of costa, describes a sharp arc in the upper 
half towards the margin and is accompanied by a fainter parallel line, that outwardly encircles the very large 
quadrangular reniform stigma. The stigma itself is divided into 3 white spots by an angulated streak pointing 
towards the base. The anterior transverse line is punctiform in its lower part, before it, in place of the orbi¬ 
cular stigma, a distinct brown dot. The dentate marginal line is outlined by dark brown. Beyond the outer 
transverse line, there is a large pale triangular patch on costa and in the apical area a few white specks out¬ 
lined in brown in place of a subterminal line. Hindwings are paler, traversed by 2 boldly arched transverse 
lines, between which and in marginal area, there are sharply prominent crescentiform marks enclosed in brown 
and of which those in subterminal area are the larger. Wing expanse: 25—26 mm. Amur territory. 
90. Genus: I>ierna Wkr. 
D. timandra Alph. (24 g). This pretty roseate species has 3 yellowish transverse lines on forewings 
and 2 on hindwings. Warren placed it among the Geometridae in the Genus: Pseudomiza Btlr. (Vol. 4, p. 328). 
It occurs from Corea to the southern Ussuri district. 
97. Genus: Slmpli cisi Guen. 
S. subterminalis Draes. (24 g) has a somewhat longer 3rd segment to palpi, than rectalis Ev. (Vol. 3, 
p. 415, pi. 72 b). The illustration in Main Volume was exaggeratedly large. Otherwise it is similar in structure but 
half as large as rectalis. Forewings quite pale buff with completely extinct transverse lines and small dark reni¬ 
form stigmatal shade. Subterminal line creamy yellow, almost arising at apex. It is obtusely angulated on 
vein 6 and slightly bent to inner margin. A very prominent deep dark shade anteriorly. Hindwings paler, sub- 
terminal line angulated on vein 2. Szechuan. 
98. Genus: ISTodarfa Guen. 
N. dentilineata Braes, resembles tristis Btlr. (Vol. 3, p. 416, pi. 72 c), but is smaller. The antemedian 
line is angulated inwards subcostally, on mediana and vein 1. A small black lunule at close of cell, the outer 
line dentate. The blackish subterminal is almost straight with whitish dots on veins posteriorly. These are 
sometimes expanded, thus seeming to form a pale band. Hindwings grey. Underside glossy pale grey, hind¬ 
wings with pale dentate subterminal. Szechuan. 
99. Genus: Zaiiclogsaatlia Led. 
Z. tarsiplumalis Him. (Vol. 3, p. 417, pi. 72 c). — fumosalis DM. are very dark, almost black-violet 
specimens, heavily dusted with speckles of black-brown on all wings, so that the markings are indistinct. Hind- 
wings similarly black-grey. S. Tyrol. 
Z. celatrix Filipj. denominates a very worn specimen, about which even the author says, that nothing 
can be said about the markings. Ground colour is darker than in tarsiplumalis , that is about all that can be 
said. Genitalia however are so different, that the species can immediately be recognised. The edge of the upper 
valve has several crenulations whilst in tarsiplumalis there is only one narrow long, very pointed spine; penis 
lias a number of small spines at distal end, which do not occur in tarsiplumalis. Wing expanse: 31 mm. S. Ussuri 
(Sutshan), in July. 
Z. tarsicristalis H.-Schaff. (Vol. 3, p. 417, pi. 74 g). — negligens DM. is a more regular bluish grey, not 
yellow-brown, the dark transverse bands faint or quite absent, the pale transverse band duskier. A smaller 
second generation. biumbralis Trti. & Ver. has a paler central band, that is edged by the transverse lines, 
whilst the basal and marginal areas appear to be more violet-blackish. Transverse lines are bolder and appear 
denser and more prominent, whilst subterminal is almost extinct. Maritime Alps (Valdieri). 
Z. tenuialis Bbl. (Vol. 3, p. 417) is now being illustrated (24 g). It also occurs in the Amur territory 
(Ussuri). 
Z. punctalis Herz. Forewings ashen grey with pale central band and elongated straight streaky stigma. 
The darker basal area is enclosed by a blackish transverse line. Posterior transverse line dentate, bending boldly 
outwards at top. Before outer margin and parallel to it, a pale grey, almost whitish transverse line. Hindwings 
paler with 2 brown transverse lines. Corea.
