Amasia and from Hadjin, Mesopotamia. Le Cerf thinks this cannot he the true taochata (Transcaucasia), 
as it has just the same shape as sabaudiata , while taochata has the wings “shorter and more rounded, the hind- 
wing less deeply dentate” (Lederer); moreover, taochata should he “olivaceous grey” and — according to 
the figure, strongly marked. — ab. oberthiiri Le Cerf , founded on a <§ from Amasia (Anatolia), has the wings oberthiiri. 
above uniform mouse-grey, a little light towards the base of the hindwing, markings almost obsolete, only 
the alternately dark and light vein-marks standing out distinctly. — To judge from a very few examples of 
this form and only 2 Transcaucasian taochata, I incline to think it is at most a mere subspecies. After this 
manuscript had gone to press, Dr. Wehrli (i. litt.) with Lederers originals before him, confirmed for me the 
sinking of this to taochata. 
T. taochata Led. (Vol. 4, pi. 5 h). More grey than the rest of the group (except -petronata, which is taochata. 
larger, with darker hindwing proximally, etc.), the terminal line more developed than in the rest; cell-mark 
strong; apex perhaps slightly less sharp. Transcaucasia. Variable, but Lederers figure incorrect in showing 
dark terminal line and paired abdominal spots (Wehrli). 
T. dubitata L. (Vol. 4, pi. 5 i) ab. fasciata Schwingenschuss is the banded form, about parallel to those fasciata. 
of T. incertata , T. amdoensis and others which bear the same name; median band black-brown. Described from 
Modling, Lower Austria. — amblychiles subsp. nov. (9 h). Subsequent experience confirms my former statement ambtychiles. 
as to the colder colour and generally weaker markings of the far-eastern race (China and Japan); this is applic¬ 
able to perhaps 90 per cent, but I further notice that practically every specimen differs from the name-typical 
race in that the tooth of the postmedian line (at and in front of the 1st radial) is blunt and double, whereas 
in d. dubitata it is produced and usually acute. I have chosen as type of the new race a from Kwei-chou in 
the Tring-Museum. 
T. sericata Btlr. (Vol. 4, pi. Ilf, as sericaria) decolor Prout (10 a). We here give a figure of the type decolor. 
$ from Kwei-chow. The race is distributed in Szechuan and not always very sharply differentiable from the 
Japanese. — oberthiiri Hedem. (= subsericata Stgr.). If, as I still suppose, all the sericata- like forms belong oberthiiri. 
to a single species, the synonym subsericata should have been cited here, not to typical sericata as in Vol. 4. 
It was founded on a Sutschan $ which was collected with an oberthiiri £ and which was smaller than the Japanese 
sericata -$, though otherwise similar — lighter than oberthiiri qq. 
T. salebrosa sp. n. (10 a). In structure an absolutely typical Triphosa. Forewing with the costa, and salebrosa. 
especially the termen, a little less curved towards the apex, which therefore appears somewhat more acute; 
coloration nearly as in dubitata (Vol. 4, pi. 5 i), a little darker, the reddish scales little noticeable without the 
lens; easily distinguished from the neighbouring large species by the very strong outward bend of the ante- 
median from median vein to cell-spot, the jagged postmedian and the purity of the white of its anterior edging, 
of its long inward projections on the veins and of the marks which form the subterminal. Hind wing with some 
of the marginal teeth very long; weak-marked, except as to the subterminal. Underside rather dark, the red 
tone very noticeable in distal area of forewing; the whitish vein-dashes, etc., moderately distinct. Omei-shan, 
August 1907, a fine in the Tring Museum. 
T. aequivalens sp. n. (= expansa Warr., nec Moore). (Vol. 4, pi. 5 k, as expansa). I find that two clif- aeqivalcns. 
ferent insects have been passing under the name of expansa Moore. The true exparisa of Sikkim (Moore's allo¬ 
type $ is merely labelled “Himalaya”, but belongs therewith) is a strongly marked species with a dark pre¬ 
subterminal shade developed posteriorly and with costal markings somewhat as in sericata Btlr. and will be 
dealt with in Vol. 12. The other, very common at Thundiani in August and September (type series in the British 
Museum) and distributed from the Murree Hills to Kumaon, is much more soberly and more uniformly coloured, 
without the costal expansion of the central bands, but with a whitish spot near tornus. Possibly a larger (length 
of a forewfing 29—31 mm), much less reddish race of venimaculata Moore of Sikkim. The 3 Pu-tsu-fong spe¬ 
cimens have perhaps a slightly warmer tinge than typical aequivalens. I have not seen the Ta-tsien-lu pair 
recorded by Sterneck as expansa. 
T. rubrodotata Walk. (Vol. 4, pi. 6 1). Common on Omei-shan, etc. The AS are much smaller and gen- rubrodotata. 
erally — at least in W. China — less brightly red-mixed in the median area than the $$; perhaps we have 
here a separate race, as I have not even seen any females with the beautifully red band which is often 
developed in Sikkim. 
T. instabilis Alph. (10 a). According to the material before me, it seems impossible to leave this in instabilis. 
the genus Philereme (= Scotosia), to which it was originally assigned. The A valve is quite un-characteristic. 
The aspect is more that of a somewhat narrow-winged Galocalpe (e. g. veternata), but neither retinaculum nor 
abdominal margin of hindwing shows any special modifications. Attention may be called to the rather straight 
termen of the hindwing. Palpus short. 
T. albiplaga Oberth. (Vol. 4, pi. 5 k). This Triphosa and those which follow' are characterized by the albiplaga. 
development of the A retinaculum into a more or less broad, firm, membranous plate, which reappears in a 
somewhat extreme modification in a Neotropical subgenus or genus which Warren has named Strepsizuga
