SCOPULA. By L. B. Prout. 
shisJcensis. S. shiskensis Matsumura. “22 mm. Closely allied to nivearia”, but pale greyish white, with scattered 
fuscous scales; lines indistinct greyish, the antemedian apparently wanting, the other 4 approximately equi¬ 
distant, the subterminals somewhat sinuous; on hindwing 3 indistinct lines; fringes concolorous, without black 
scales. Underside with cell-dots, forewing with the outer 3 lines close together, more distinct than above, 
hindwing with an obsolete submarginal band. Antennal joints in <$ somewhat projecting, with moderate cilia. 
Hindtibia of $ without spurs, long hair from its base. S. Saghalien, both sexes obtained. 
nemoraria. S. nemoraria Hbn. (Vol. 4 pi. 4 k). My suspicion that the Eastern Asiatic records of this species might 
refer to superior (Vol. 4, pi. 4 m) is not confirmed; true nemoraria reaches Vladivostok. Sterneck has pointed 
out that the 2nd subcostal and 1st radial of the hindwing are stalked in nemoraria but not in superior, the 
liindtarsus a little less abbreviated in nemoraria. Moreover the genitalia show material differences. 
subpuncta- S. subpunctaria H.-Sch. (Vol. 4, p. 69, pi. 4 k). An unexplained and very puzzling dimorphism in the 
ria. 8th sternite of the q probably points to incipient species-divergence, but it has hitherto been found impossible 
to correlate it with any other character. In the form which (in the absence of a historical “type” for examin¬ 
ation) is considered typical, the cerata are highly asymmetrical (see under prouti Djakonov ). —- There occurs 
with it, however, in most localities (e. g. the Pyrenees, Austria, Hungary, Caucasus) a form in which these are 
isoceras. equal, in this respect, though not in others, resembling prouti ; I name it provisionally f. isoceras nov. It would 
be very interesting to learn whether both forms can occur in an individual brood, or what part heredity plays 
in the phenomenon. Unfortunately the type of my ab. exstirpata, St. Egid, Lower Austria, is a 9- — ab. (?) 
depundata. depunctata Guen. (6 h). According to Culot this is a distinguishable aberration, whiter and with the subterminal 
shades wanting. The locality of the assumed “type” is not given and it is uncertain whether the name should 
be regarded as a nomen novum for the preoccupied punctata Scop., which Guenee cites, but hesitantly. 
prouti. S. prouti Djakonov, sp. n. (5 b, $). “Nearest to subpunctaria H.-S. Presumably all the specimens 
from E. Asia ascribed to subpunctaria belong to this species. The $ genitalia are similar to [those of] sub¬ 
punctaria, but have a definitely different ventral plate (8th sternite). In subpunctaria the lateral processes 
of the ventral plate (cerata by Pierce’s terminology) are asymmetrial, the left being shorter than the covering 
flap (mappa) and strongly uncinate, the right, on the other hand, longer than the flap and only weakly curved. 
In prouti these processes are equal in length and as long as the flap. The subunci (socii) in subpunctaria are 
considerably longer and more strongly developed than in prouti, at their tips, moreover, more widely sepa¬ 
rated. The specimens of prouti are as large as medium-sized subpunctaria, the termen of the hindwing quite 
rounded. The $ hindtarsus is noticeably longer and the antennal ciliation likewise distinctly longer than in 
subpunctaria. The upperside of both w r ings is white, about as in subpunctaria , the dark irroration on the whole 
coarser and denser (in some specimens rather sparse). The irroration is strongest along the costa. Both wings 
bordered by a faint yellowish-grey line, which somewdiat recalls caricaria (Vol. 4, pi. 4 k), but the black cell-dots, 
as also the terminal dots are entirely wanting in prouti. The lines are yellowish brown, similar to those of subpuncta¬ 
ria, yet somewdiat broader and only very w r eakly waved, not denticulate; when all are developed, they are parallel 
inter se, to the number of 4 on each wing; by no means rarely, however, some of them are obsolete, so that 
exceptionally only one distinct line on each wing is left. The strongest line is the postmedian, which is always 
present and continues on the hindwing; median generally also strong, the others weaker, usually very weak, 
appearing only through their darker scaling. On the underside a distinct costal dot is present on each wing. 
The dark irroration is still stronger than above, but not so strong as in subpunctaria. Of the lines, only the 
postmedian is always present, usually very strong; the rest are very weak, often for the most part not appre¬ 
ciable. The brown-yellow terminal line is rather strong on both wings, between the veins somewhat broadened 
into spots; in subpunctaria black spots are here distinct. The 9$ are on the whole purer white, almost without 
irroration, with broader yellow lines, very faintly visible cell-dot and small black marginal dots in the anterior 
part of the forewing. Amur-Ussuri district, widely distributed; westward as far as Blagowestschensk. June till 
July. A long series in Zool. Mus. Leningrad” (Djakonov in litt.). Specimens from Japan, on an average 
somewhat larger and occasionally showing (small) black cell-dots on the upperside, perhaps represent a 
separable race. 
anonyma. car ^caria Reutti (= phlearia Reutti) ab. anonyma Schawerda, a 9 from Mecklenburg, is wholly white, 
nigrocingu- even the cell-dots wanting, the lines almost invisible. — ab. nigrocingulata ( Dannehl, M. S.) Hartig has the 
tutu. cos tal edge of the forewing and the distal margin of both wings black-scaled, the preceding line (subterminal) 
also blackened. S. Tyrol, the type 9 from Terlan, a Bozen $ also showing some approach to it. 
klaphecki. S.klaphecki Prout (5b). Very similar to caricaria (Vol. 4, pi. 4 k), but with the collar white, the costal margin 
of the forewing on an average rather more strongly irrorated, the cell-dot sharper and blacker, the subterminal 
nearer to the termen, the latter with well developed black dots; postmedian line perhaps more bent, especially on 
the hindwing, and somewhat more distally placed. N. China, the typical pair from Tsingtau, Shantung (L. 
Klapheck), others from Pekin, all dated August. Almost certainly the Amur species recorded by Graeser
