K. bioerraria Pung. (14 k). Near staudingeri. The pectinations in the type' appear to be appressed 
to the antennal shaft (perhaps accidentally); the gronnd-colour is lighter (whitish grey), not nearly so brown¬ 
ish as in staudingeri, the basal patch of the forewing far more irregular, with a longer subcostal projection, 
the antemedian with deeper but more rounded projections, the postmedian with shorter and more regular 
teeth. Founded on a pair from Altschan (Altyn-Tag); also known from Korla. 
K„ loxobathra sp. n. (8 b). Smaller than oberthuri (Vol. 4, pi. 11 a), the type measuring 40 mm, hind¬ 
wing scarcely so narrow (its apex somewhat less pointed). Forewing with subbasal line strongly oblique 
throughout, much less excurved in middle, more broadly darkened, the antemedian more oblique inward 
posteriorly; postmedian with a stronger outward projection at the 3rd radial and consequently a more notice¬ 
able bay between this and the small posterior projection; distal area more weakly marked, in the type almost 
unicolorous, with weak dots on the veins in its proximal half; cell-dot in the type wanting above, faintly in¬ 
dicated beneath. Hindwing somewhat whiter than in oberthuri, with the postmedian well angulated at the 
3rd radial, strongly incurved posteriorly. Amdo, the type in my collection, received as oberthuri; another 
in the Hamburg Museum. — dignitosa subsp. nov. (= lakearia Sterneck, nec Oberth.) (8 c). Less small and on 
the whole more variegated, sometimes recalling a less red-marked Kyrtolitha purpureotincta (7 d); cell-dots well 
developed. Thus less far from oberthuri in aspect, but conserving the essential characters (subbasal and post¬ 
median) of loxobathra. Ta-tsien-lu, type $ (figured) and another with broader band in the British Museum, 
a third $ (Tring Museum) representing a narrow-banded aberration; others from the same district known. 
Also from Sunpanting, W. China (Stotzner), determined by Sterneck as lakearia Oberth. (Vol. 4, pi. 6i) prob¬ 
ably misled by my erroneous suggestion of a connection between the latter and oberthuri. 
K. productaria Leech (8 c). We now give a figure of the type <$ (see Vol. 4, p. 165). I still know no 
other example. 
8. Genus : Mesotype Him. 
(See Vol. 4, p. 166.) 
This remains a monotypical genus, perhaps better associated, as was already hinted, with the Cata- 
clysme group. The inclusion of undata Stgr. was on structural grounds quite erroneous; see Zola. 
M. virgata Hufn. ab. mediofasciata Schwingenschuss, described from 2 $$, Lower Austria, is white- 
grey with the secondary lines obsolescent, those of the central area of the forewing consolidated into two 
largely confluent bands. — ? gen. aest. (? ab.) diluta Galv. is a yellowish form, variable in the exact colour, 
which is prevalent in June and July, particularly in the East and S. E. of Austria. — ab. loc. contrariata 
Heydem. (8 c). Paler than the typical form (Vol. 4, pi. 6 c), the ante-and postmedian lines accompanied by 
more definite dark shades, which give to the insect a much brighter, more variegated effect; generally best 
characterized in Described from Annum, mentioned also for Kiel and England; it nowhere, so far as is 
known, forms a contrast race, but is interesting as being another of the products of the “Atlantic climate" 
(compare 0 . mucronata plumbaria). 
9. Genus: Bastilta Moore. 
(See Vol. 4, p. 166.) 
It is probable that this genus and several other smooth-faced Larentiine genera have really more 
affinity with the Sterrhinae, but as some inferences drawn from the genitalia, the forewing venation and per¬ 
haps in some cases the scheme of markings are by no means conclusive, it is more convenient to retain them 
in the present subfamily, as characterized by the costal of the hindwing. 
H. subfalcaria Christ. (14 i). The Japanese specimen mentioned in Vol. 4, p. 167 under the name of 
S. caeruleolineata, a $ from Jozanke, near Sapporo, Yezo, is much worn and torn, but apparently (by its 
shape) S. subfalcaria , so that —as already surmised — subsp. caeruleolineata may be deleted from the Palae- 
arctic fauna. 
H. azela Btlr. stenozona Prout (8 c). Forewing with the dark posterior cloud of distal area stronger 
than in A. azela, confluent with the proximal dark colouring. Hindwing above with the dark band narrower 
and more distally placed, the white area beyond it somewhat narrowed; beneath with the proximal area, as 
far as the median line, dark-shaded. A pair from Hpimaw Fort, Kachin Hills, Upper Burma; mentioned here 
because 2 $$ from W. China (Kwanshien and Mt. Omei) agree so closely that, at least until more Chinese 
specimens are available, no further race-name can be established. Both are rather small.
