(aberrans Warr., gavara Druce, umbrifacta Prout) and — as already in part indicated in the note at the head 
of the present genns — in several Calocalpe. Its taxonomic value is not yet ascertained, but the morphological 
study will be well worth pursuing. A race ( ?) of albiplaga , either from Japan or possibly Formosa is repre¬ 
sented in the Joicey collection by a single example; but the uncertainty as to its origin, even more than the 
lack of confirmatory material, prevents my dealing whit it at present. 
T. nigralbata Warr. (Vol. 4, pi. 7 1, as albiplaga). Perhaps more blackish brown. Forewing with the 
oblique white patch ampler, the transverse series of white dots differently (on the whole better) developed, 
the antemedian costal mark oblique, the subterminal series developing a narrow mark opposite (well detached 
from) the oblique patch (in albiplaga a broad spot), the spot close to the tornus enlarged. Kashmir to Sikkim, 
the type from Thundiani; a $ which absolutely belongs here by my differentiation, was collected by Mr. H. 
Stevens (Kelley-Roosevelt Expedition) at Tu-pa-keo (Mupin), 7400 feet, 7 September 1929. 
T. incertata Stgr. (Vol. 4, pi. 8 d) is perhaps a small, somewhat browner northern race of dubiosata ; 
some of the distinctions given in Vol. 4 (p. 198) are very slight or inconstant and the structure appears to be 
the same in both; but the less bent lines of the hindwing underside in incertata may be significant. 
T. dubiosata Walk. (Vol. 4, pi. 11 g). This has frequently been quoted as Scotosia or Philereme dubio¬ 
sata , but the genitalia show no connection with those of true Philereme, yet are nearer to Calocalpe (e. g., cer¬ 
vinalis) than to typical Triphosa. Common from Afghanistan to Kurnaon. The $ from Hakodate, recorded 
by Wileman, must surely have been misidentified, but cannot be traced in his collection. — The larva of dubiosata 
feeds on Berberis (Hocking); a preserved larva in the British Museum recalls Philereme vetulata. 
T. tremulata Guen. (10 a) founded on a pair (not 2 $$, as published) from North India, in not very 
fresh condition, is perhaps not strictly Palaearctic. I suspect that they came from Masuri, the best-known Indian 
locality and one from which Guenee evidently received Geometridae. Moore many years ago labelled a N. 
Indian $ of the species which has since passed as multilinearia Leech as agreeing with Guenee's type, and the 
description, supplemented by information supplied by Dr. Wehrli, entirely supports him. Hampson in 1895 
nevertheless entirely misidentified it, describing a purely Indian Calocalpe as Scotosia tremulata. All the speci¬ 
mens known to me from Masuri agree in having the white subterminal dot of the forewing in cellule 2 better 
developed than in the Chinese form, but otherwise the resemblance is wonderfully close; and as I have a pair 
from Nainital (Kurnaon) which agree with the latter, not with the former, it would perhaps be justifiable to 
reunite the two (provisional) races. — multilinearia Leech (Vol. 4, pi. 13 d), which has been recognizably described 
and figured, is abundant in West China and tolerably constant. The figure is perhaps scarcely dark enough 
and does not quite adequately bring out the relative strength of the two white subterminal dots (central 
and posterior); variation is generally in the direction of weakening, rather than strengthening, the rest of the • 
series (see the differentiation of name-typical tremulata ,). 
T. confusaria Leech (Vol. 4, pi. 13 c) has also some races or very close relatives in India (Sikkim-Tibet 
and Bhotar), which will be considered in Vol. 12. 
46. Genus: (lalocal|»e Him. 
(.See Vol. 4, p. 199.) 
The connection with Triphosa was noted in Vol. 4 and has been adverted to, from another standpoint, 
in the account of Triphosa above. In another direction, a really near relationship with Eulype (which still 
stands as a section of Cidaria!) has only gradually been realised, but is supported by so many characters that 
it cannot be a mere illusion attributable to convergence. The build and habits of the larvae, the structure of 
the genitalia, the venation of the hindwing, the transition from a double to a simple areole (see Vol. 4, p. 201, 
latifasciaria) and even the specialised coloration and wing-pattern of the last few Calocalpe all point in the 
same direction. 
C. cervinalis Scop. (Vol. 4, pi. 5 i). A further synonym, overlooked in Vol. 4 (as also by Sherborn in 
his Index Anim.) is ancipitata Tr., published in October 1925 as a correction for the supposedly erroneous use 
of cervinata Hbn., therefore actually having priority over the long-established certata Him., which was erected 
for the same purpose. The naming of aberrations in this variable species has proceeded energetically. — ab. 
atra Kiefer. Forewing strongly blackened, slightly glossy; hindwing lighter, especially towards the base. Both 
without any markings, the dark marginal line distinct, “the fringes lighter, chequered". Near Admont, Stvrian 
Ennstal. A more extreme development than ab. infuscata Rbl. (10 a), of which we figure a $ from Sprottau. 
Rebel records a transition from Modling and doubts the chequered fringes. — ab. unicoloraria Schwingenschuss 
is of a uniform rust-brown colour, so that the median band has altogether vanished; the lines indicated by light 
spots along the costa of the forewing and marks on the veins. St. Peter in cler Au, Lower Austria. — ab. variegata 
Schwingenschuss . Forewing much variegated, bright brown-red, with white-grey or yellow-grey bands bounding
