BREPHOS; LEUCOBREPHOS. By L. B. Prout. 
i 
1. Subfam.: Brephinae. 
1. Genus: ISrephos Zinck. 
(see Vol. 4, p. 1 and Vol. 8, p. 5.) 
B. parthenias L. (Vol. 4, p. 1, pi. la) ab. dilutior Heinrich is small, with the white markings much dilutior. 
reduced. — ab. unicolor Heinrich is still more extreme, the white markings entirely suppressed, except in the unicolor. 
chequered fringes. — ab. brunnea Closs is described as having the forewing above and beneath unicolorous brunnea. 
brown. All the above were described from Berlin. — ab. nigra Tutt (Vol. 4, p. 1) has as a synonym extrema extrema. 
Rbl. (1910), the types respectively from the Dale and Mazzola collections. — ab. muliercula Stephan. Hind- muliercula. 
wing pale reddish yellow, with the black markings much reduced, cell-mark very small, well isolated. Described 
from the Erzgebirge, but occurs occasionally in many localities. A modification of muliercula, with the fore- 
wing of unicolor, is figured from a Paris $ in Ann. Soc. Ent. Fr. (3) Vol. 6, pi. 14, fig. 6. —- ab. szymanskii szymanskii. 
Isaak is at most another slight modification cf muliercula , black bands of hindwing almost entirely lost, the 
black shade on inner margin very much reduced, the markings of the forewing also weakened. Zawiercie, Po¬ 
land. — ab. luteata Hennin has the hindwing above and both wings beneath pale clear yellow. — ab. flava luteata. 
H. W. Wood (la) is perhaps synonymous, but the forewing lacks the usual reddish suffusion, and no mention f lava - 
of this change is made in Hennin’s description; flava is a recurrent form at Wimbledon. — sajana Prout (1 a) sajana. 
seems to be diverging not only in shape (see Vol. 4, p. 1) but also in the somewhat less projecting joints of the 
E antenna. Perhaps an incipient species, but I can see no difference in the genitalia. 
B. notha Hb. (Vol. 4, p. 1, pi. 1 a), ab. laeta Rbl. (1 a). Forewing white-grey with broad black-grey laeta. 
median band which is more extended outwards, and with the hindwing uniform bright orange-yellow except 
for a weak darkening at the inner margin. — suitunensis Kardakoff (la). Hindwing pretty typical, perhaps suifunensis. 
with extension of the dark markings costally; forewing darkened, with a Avhitish central patch nearly as in 
parthenias. A local race from Ussuri to the Chingan Mountains. 
B. puella Esp. (Vol. 4, p. 2, pi. 1 a), ab. latevirgata Kitt (1 a) has the proximal band of the median latevirgata. 
area of the forewing strongly darkened. — ab. inversa Nitsche. Forewing somewhat darkened, with a curved inversa. 
black postmedian band, which forms an angular projection outward between the radials. 
B. ussuriensis Moltrecht (lb) is said to be intermediate between B. puella and L. middendorfii. Very ussurien- 
hairy. Forewing slate-grey, subterminally becoming darker; basal band sharply black, excurved behind the s?s - 
cell; distal dentate band black, externally bordered with yellowish white, behind the end of the cell with very 
strongly projecting tooth. Hindwing white, basal area dusted with grey, no discal spot, a broad grey-black 
distal border. Found in the snows of March, in forest 300 km north of Vladivostok. Should perhaps be referred 
to Leucobrephos ; Dr. Y\ ehrli. suggests that middendorfii nivea may be synonymous with it. 
2. Genus: Leucobreplios Grote 
(see Vol. 4, p. 2.) 
L. middendorfii Men. (Vol. 4, p. 2, pi. 1 a), nivea W. Kozhantchikov is a smaller form, the forewing nivea. 
darker, the hindwing with more extended basal darkening and considerably broadened black border. Founded 
on 5 from the Sajan Mountains, taken on 7 April. Perhaps sinks to ussuriensis (see above). 
2. Subfam.: Oenoehrominae. 
(see Vol. 4, p. 2 ; Vol. 8, p. 6; Vol. 12, p. 5 and Vol. 16, p. 3.) 
Since the publication of Vol. 4, various modifications in the composition of this heterogenous sub¬ 
family have been proposed or would seem desirable. The genitalia of Aplasta and some other characters should 
certainly refer it to the Hemitheinae, as had already been suspected. Phyllometra (= Egea) is considered by
