cell-spot very large, black; 2 black costal spots, at y 3 and %; 4 proximal lines marked by dark vein-dots; 
postmedian double, strongly excurved at costa, then parallel with distal margin; subterminal line weakly den¬ 
tate, accompanied proximally by one, distally by two dark lines; fringe distinctly chequered. Hindwing light 
grey, the lines only distinct in posterior part. 1 $ from China, without locality. 
D. fenestrata Mill. (Vol. 4, pi. 13 h) ab. mediopunctata Dietze has more or less distinct cell-dot present 
on the forewing above. 6 examples known to its author, the type from Fenestre. — ab. inanis Dietze is pure 
white, with remnants of the brownish markings at the costa. Alios, France, obtained by breeding; as 4 out of 
the 5 were small Dietze calls it a “hunger-form”. — ab. confusaria Dannehl. Unusually strongly marked, 
often with a light brown tint; lines broadened, very brown. Monte Baldo, 1800 m (loc. typ.) and singly from 
the Ortler and Carinthia. — ab. perlineata Dannehl. Much rarer. White, the lines scarcely visible excepting 
the ante- and postmedian, which are very pronounced. Monte Baldo (type), etc. 
E„ cerussaria Led. (Vol. 4, pi. 13 g). According to Dr. Cockayne’s researches this is the only fluorescent 
Eupithecia , on which account he suggests that it is not properly congeneric. The areole is also perhaps not 
quite normal, usually very narrow in proportion to its length, yet rather variable; but I can scarcely yet feel 
that tlie generic placing can be incorrect. Occurs on Cyprus in March and April. 
E. cauchiata Dup. (Vol. 4, pi. 12 g). Dietze thinks that majoraria Lah. = griseimarginata ( Brd ., ined.) 
Lah. may represent this species rather than scabiosata, to which it was provisionally assigned by Speyer and 
others. On a careful examination I conclude that Dietze is obviously right, though the type figure is crude. 
Sweden is a further locality for cauchiata. 
E. amplexata Christ. (Vol. 4, pi. 13 i). It was demonstrated long ago by Petersen that, especially 
according to the genitalia, this should be placed in the satyrata group, not near subumbrata or denticulata. 
pryeriaria Leech, from Hondo and Yezo, is almost synonymous with amplexata and I formerly sunk it 
(though the name was accidentally omitted from Vol. 4). But as all the Japanese examples which I have seen 
have the cell-dot very small (which is a very rare occurrence in amplexata) I now regard it as a race. 
E. scribai sp. n. (18h). Palpus iy 2 . Ciliation even, about y 2 or little over. Creamy white, with the 
markings light yellow-brown, as in rather pale pryeriaria , to which evidently it is nearly related. Forewing 
with cell-dot very small and weak; lines slender, costally somewhat expanded and darkened; first group other¬ 
wise indistinct except the antemedian, to which succeeds a clean space to just beyond cell-dot; postmedian 
series rather strongly angled outward, then oblique inward, the proximal one touching the cell-mark posteriorly; 
subterminals weak. Hindwing concolorous; about 4 proximal lines (weak except the last of them) and a lunulate 
postmedian. Underside well banded, differing especially from that of pryeriaria , the subterminal forming a 
broad white band. Sachalin, 28 July 1923 (Dr. Scriba), type £ in the Seitz collection. 
E. aggregata Guen. D jakonov finds the genitalia in both sexes indistinguishable from those of pernotata 
(Vol. 4, pi. 13 h) and therefore regards aggregata as merely a local race. This name has page-priority, but as 
Guenee knew b o t h sexes of pernotata and only a single $ of aggregata, Djakonov has made a wise selection 
in choosing pernotata as the name of the collective species; assuming his premises, this nomenclature must be 
accepted. Specimens from the Ussuri, and even from Japan, are sometimes confusingly similar to pryeriaria. 
except that the cell-dot is obsolete; I do not know whether any exact anatomical investigations have been 
undertaken. 
E. serenata Stgr. I overlooked Dietze’s statement that this “seems nearer to pernotata than to saty¬ 
rata" . I have no material for comparison, but as Staudinger refers to “an old $ from Altai, from Lederer's 
collection'' as agreeing “almost” entirely and it is reasonably safe to assume that that specimen w T as one of 
the originals of rivosulata (see below), the synonymy given in Vol. 4 (p. 285) may probably be correct. Stau¬ 
dinger stresses as particularly characteristic of serenata the “very strikingly broad and light (almost white)” 
line which, “as never in typical satyrata'’, delimits the narrow, somewhat darkened distal area. The type came 
from Amdo; according to Dietze Koko-nor is to be added to its range. 
E. rivosulata ( Led., MS.) Dietze (18 a). Of this Eupithecia, Dietze’s belief that “the types no longer 
exist” is fortunately not correct. Even if the Altai $, referred to under serenata, was not one of them, or is 
lost, there is in the British Museum, from the Zeleer collection, a $ bearing the label “ rivosulata Led., Altai. 
Led. 1, 54". We figure this, which seems to agree well with Dietze’s forms from Sojmonowsk, Central Ural, 
especially his figures 208 and 936. It has a more deeply dentate subterminal line, perhaps also a little nearer 
to the distal margin, than pernotata and this may also help to separate it from serenata ; otherwise very similar, 
though the postmedian is perhaps somewhat more acutely angled at the 1st radial. To aggregata and fusci- 
costata. which are also compared, I take it to be less close. 
E. italicata Guen. In Vol. 4 (pp. 291, 292) I followed Dietze, who has cited this name quite tentatively 
to graphata Tr., sens. lat.. but this was evidently erroneous. The type, a from Domodossola, measured only
