some good observers to be better placed in the Geometrinae, on account of the obsolescence of the 2nd radial 
of the hindwing, and a tendency in the same direction is observable in Phthorarcha; probably none of the 
Alsophila group can remain permanently in the Oenochrominae (see Vol. 8, p. 7). Odezia possibly and Palaeo- 
mystis certainly should be associated with the Larentiinae. On the other hand Eumegethes Stgr. must needs 
be placed here, as also Drepanopterula Hedicke. 
1 . Genus: Alsophila Hbn. 
(see Vol. 4, p. 2 and Vol. 8, p. 6.) 
A. aescularia, Schiff. (Vol. 4, p. 3, pi. 1 a) ab. brunnea Hannemann is darkened with blackish brown. 
A. quadripunctaria Esp. (Vol. 4, p. 3, pi. 1 b) ab. umbrata Heinrich has the median area of the fore¬ 
wing distinctly darkened with blackish grey. Described from Berlin. 
3. Genus: Phyllometra Bsd. 
This name, adopted by Boisduval in 1840 from Rambur’s manuscript, is the oldest for the genus 
which has since been known as Egea D\ip. (Vol. 4, p. 5), and although the descriptions of the genus and of the 
species (gracilaria) were combined and very brief, it is evident that the names will have to be restored. 
Dr. A. Djakonov lias made a study of the venation and genitalia and considers the affinities to be 
quite definitely with Narraga. Isturgia, Psodos and Pygmaena. Actually there is no “vein 5” on the hindwing, 
its position being occupied by a strong, scaled fold, as in a good many so-called Geometrinae, though not speci¬ 
ally in those with which he associates it. More weighty, probably, is the evidence from the genitalia, which 
may ultimately be made a basis for re-classification. 
Ph. culminaria Ev. The $, which is rarely taken, has been recently redescribed and figured from 
Hungary by Dr. A. Schmidt, under the impression, apparently, that it was previously unknown. It was, 
however, known to Guenee and is briefly referred to in the generic description in our Vol. 4. The first record 
of the species for Hungary was made by Prinz in 1913. 
Ph. gracilaria Bsd. (= cacuminaria Rmb.) (Vol. 4, p. 4, pi. 1 b). According to Boisduval (Gen. et 
Ind. Meth., p. 193), Rambur originally named this species gracilaria, but we owe the brief diagnosis, with 
indication of the locality, Andalusia, to the work just cited. 
Ph. argentaria B.-Haas. We have no further information about this Phyllometra, which was described 
from Foume Tatahouine, Tunis, but it seems highly probable that it is a weakly marked example of the follow¬ 
ing. The name argentaria will in that case take priority. 
Ph. planaria Chret. (1 b). We figure a A from Guelt-es-Stel; planaria is distributed in Algeria in April 
and early May, and is probably nothing more than a large race of gracilaria, .with sharper white markings. 
Unless the Tunisian form is really different (see above), the correct synonymy will then be “ gracilaria argen¬ 
taria B.-Haas (— planaria Chret.)”. 
3a. Genus: Autotrieliia nom. nov. 
This genus, which obviously required to be separated from the preceding, was named Orthotrichia 
Wehrli (1927), but as that name had already been employed in Zoology (Wingate, 1886) it is necessary to 
supply it with a new name. Scaling quite different from the normally and appressed scaled Phyllometra ; 
surface of the wings covered with oblique or perpendicular scales of three forms: (1) normal broad ones 
in varying quantity; (2) very narrow, hair-like scales with their tips two-pointed; (3) ordinary simple hair- 
scales. Venation not uniform, varying and sometimes asymmetrical; hindwing with costal free or anastomosing, 
2nd subcostal connate to remote (in Phyllometra more or less stalked), “2nd radial wanting, the fold simulating 
a vein."’ (But it cannot be said to be really “wanting” in lysimeles.) The scarcely perceptible markings quite 
different from Phyllometra. Genotype: heterogynoides Wehrli. 
A. pellucida Stgr. (Vol. 4, p. 4, as Egea) (1 d) differs from the other species in possessing a noticeable, 
though weak, postmedian line. We figure the type from the Elwes collection. —- impellucida Djakonov is 
more densely scaled and better marked, the ground-colour deep chocolate-brown, the lines brighter, more 
ochreous. Central Altai: Ongudai, Kreis Bijsk. 
A. lysimeles Prout (1 b). Closely related to pellucida, larger and somewhat longer winged, greyer, the 
markings entirely obsolete, though the costal and distal margins of the forewing look slightly more coloured 
than the rest, on account of the somewhat less sparse scaling of these areas. Antennal pectinations somewhat 
more slender and lax than in pellucida. Central Altai. 
A. heterogynoides Wehrli (1 d). Antenna of A with 24 joints pectinate (in pellucida 26, in lysimeles at 
least 28). Further distinguishable from lysimeles by the smaller size, the still greyer (not brownish) tone, per-
