bands approximated, the pale space between them consequently narrow. — ab. mixta Harrison. “Fasciae 
with individual striae diffuse." None of these aberrations appears to be at all localised. — ab. ovulariata 
(Oberth. MS.) Culot. Markings weak, except subbasal line and narrow dark median band, which latter encloses 
two patches of the ground-colour, the posterior one narrow, divided into three by fine lines at the fold and 
the second submedian. Founded on a d from Scotland. 
0. viridipurpurescens (Matsumura, MS.) sp. n. (9 h). Expanse 32—34 mm. Face blackis|h fuscous, 
crown green. Antennal joints projecting, much as in dilutata. Abundantly distinct in the delicate green ground¬ 
colour of the forewing, reddish-grey markings, much less bent antemedian group of lines, absence of strong 
costal markings of hindwing, etc.; postmedian of forewing sinuous, cell-mark wanting. Some details of shape 
and markings suggest that it is somewhat intermediate between the present genus and Operophtera, but the 
tongue is well developed and the discocellulars of the forewing not biangulate. The discovery of the § will 
be of great interest. Mount Kurama, near Kioto, 16 November 1920 (I. Sugitani), 2 <$$, the type in the 
British Museum, more strongly marked (especially on the hindwdng) than the figured specimen. 1 have also 
a much wasted from Owakidana Japan (M. Culpin). 
0. (?) mediolineata Prout (Vol. 4, pi. 13c). 1 transferred this very distinct species to Oporinia on 
account of its general characters and November flight and its fully winged $, but both wings have the disco¬ 
cellulars biangulate (as in Operophtera and the American Paraptera), so that it is really out of place here and 
should probably be given a separate genus. Palpus and tongue short. Antennal joints of S moderately pro¬ 
jecting. Frenulum non-functional. Locally common in the Kioto district, Nikko, Osaka, etc. Variation slight. 
45. Genus: Trlpliosa Steph. 
(See Vol. 4, p. 197; Vol. 16, p. 91.) 
Since the appearance of Vol. 4, I have provisionally accepted the reference, by Aurivilliits, of two 
African species to this genus, but it is by no means certain that they have any really close relationship to the 
rest. Judging by the genitalia, typical Triphosa is also well removed from typical Calocalpe and Pierce 
considers its nearest (British) relative to be badiata ScMff. (Earophila) . In any case, some strikingly parallel 
developments in the £ retinaculum (compare, particularly, the “corneous plate" of T. dubiosata — noticed 
by Hampson — with that of the similar C. tremulata Guen. — apparently overlooked by Hampson) point 
clearly to the consanguinity of some of the forms which are at present separated solely in accordance with the 
presence or absence of the <J hair-tuft of the hindwing. 
T. sabaudiata Dup. (Vol. 4, pi. 5 h). The Spanish form, or at least that of Albarracin, is said to be 
relatively more strongly marked than the name-type. The species and forms of this group have been revised 
by Le Cerf, but I cannot accept all his conclusions. He gives the distribution of true sabaudiata as Central 
and South Europe to Persia and Central Asia, adds a new record for Kabylie, treats taochata as potentially 
a separate species and erects two new though closely allied species; see below. — ab. millierata Brd. (— thierry- 
miegi Le Cerf). Le Cerf argues that Bruand's millierata w as an aberration of Calocalpe cervinalis, notwithstanding 
that the type was taken in August and that its author and artist do not notice the hair-tuft of the hind¬ 
wing; he therefore re-names the banded aberration of sabaudiata , founding his thierry-miegi on another Be- 
sanQon (J. The original figure, however, shows the wing-shape, pale fringes and other features of sabaudiata 
and as Lederer, unlike Le Cerf, saw the type, no case has been made out for the change. — ab. eugramtna 
nov. (= taochata part., Stgr., nec Led.). Slightly more greyish, the lines less feebly expressed, a definite sug¬ 
gestion, on both wings, of a band-like shade proximal to the subterminal. Best developed in a few 2$, generally 
of large size; type a $ from Besan^on, in the British Museum. Occasional in most localities, including Digne, 
where I suppose it has given rise to the idea that taochata occurs in that locality; 2 of my 3 $$ from Abries, 
Hautes-Alpes, belong almost to this form. 
T. petronata Le Cerf (9 h). Very close to sabaudiata , making an impression of a browner or greyer tone, 
the markings less vague, forming, by accumulations of the slate-grev irroration, a band-like appearance of 
which there is usually no indication in sabaudiata. The genitalia, which its author carefully and minutely 
studied, show some distinctions. Discovered on the summit of Monte San Petrone, Corsica, 1768 m, end of 
July; subsequently taken on Monte Incudine (1900 m), the Col de Vizzavona and perhaps other suitable spots 
in the island. It frequents caves, like its nearest allies. 
T. agnata Le Cerf (= taochata part., auctt , nec Led.). Very similar to sabaudiata and petronata but 
smaller, in some respects intermediate between the two. Paler than the latter, darker than the former and 
reddish- or brownish-grey rather than cinereous grey; has the same festooned lines as petronata, but they are 
less sharply defined and without the interlinear dark irroration; the light and dark marks on the veins are 
better developed, notably on the'hindwing, and the yellowish white line which bounds the postmedian, as also 
the subterminal, is more regular and better expressed. Type from Caesarea, Cappadocia, other examples from
