B. pyrenaea Obtln. (Vol. 3. p. 21, pi. 4f) (2 h). As already mentioned under perla I meanwhile hold 
this to he a genuine species. Same is not solely confined to Spain, hut occurs also on S. Tyrol and in very 
large dark specimens in Zermatt. Similarly to lutescens of perla, forms also occur suffused with yellow-red: 
- rosina Gulot. The solution of the problem of perla and related forms must be reserved for future more 
exhaustive research. 
B. pseudoperla Rothsch (2 i). established from a from Guelt es Stel. in Algeria. Head and thorax 
grey-white the latter peppered with brown-grey. Fore wings grey-white speckled with brown-grey with numer¬ 
ous dentate black lines and with a large grey antemedian spot inwards of the orbicular stigma; fringes grey- 
white with black checks. Hindwings mouse-grey with white fringes. 
B„ du seutrei Obth. also closely resembles perla ; it is somewhat smaller, markings more delicate and 
more clearly defined on whitish ground; spots and lines black, between same yellow-red spots as in many 
lichen kinds. Varies considerably in paler and darker colouration. Morocco in August. 
B. antias Culot (2 h) of same size as perla but less delicately built. Ground colour of forewings pale 
fleshy reddish ochre, finely sprinkled with brown, the brown orbicular stigma elongated below the median 
nervure along the inner line, reniform stigma small and round, other markings fairly similar to those of perla. 
Hindwings whitish grey somewhat duskily brownish in marginal area and with delicate brown streak in cell. 
S. Oran, Sebdou, Geryville, Guelt es Stel. August to October. 
B. paulina Stgr. (Vol. 3, p. 21, pi. 4h) (2 1) has also been discovered in Egypt. 
B. splendida 0. B.-Haas (2 i) is to be classified after obscura Warr. Forewings black at base, then 
greenish white wherein is situate a long, broad black streak-like mark; in the olive green discal area there 
is the reniform stigma with black dot in centre and white surround; the blue-green marginal area is a half¬ 
way shade between basal and discal areas and has 3 black dots at costa, anal angle and a triangular one in 
centre; both transverse lines are black, slightly undulate. Hindwings brownish grey. Wing expanse 21 mm. 
From Sutshansk, S. Ussuri in July. 
B, mimouna Obth. resembles commixta Warr ; forewings yellowish or faintly rose-whitish with heavy 
silky gloss, coarsely sprinkled with blackish grey so that the transverse lines are not clearly apparent; sub- 
basal and inner lines somewhat more distinct than the elbowed line; 2 faint patches in discal area. Hind¬ 
wings of same ground colour as forewings. Morocco in August. 
B. syrticola Trti. (2 i) reminds one strongly of reclilinea Warr. I have no specimen before me and 
therefore cannot decide whether there is a specific difference from the form named. According to the descrip¬ 
tion the forewings are yellowish earthy grey with 3 extremely delicate black transverse lines of the same 
shape as those of rectilinea but according to the illustration the posterior line is situate nearer the margin, 
the colour is more reddish, hindwings more brownish. — In trapezoidalis Trti. (2 i) the discal area between the 
lines is adumbrated in the form of a trapeze, hereby resembling ereptricula. Cyrenaica (Bengasi) in October. 
19a. Genus: Occleremla Hmps. 
Very close to Bryo'phila, differing by the somewhat longer palpi and a rounded projection on clypeus 
with a horny process under same; more hairs admixed in covering of thorax and besides on the metathorax 
there is a tuft of loose hair on prothorax. Everything else is identical. Culot names the Genus Jugurthia. 
Type of the Genus: Oe. lithoplasta Hmps. 
Oe. diadela Hmps. (2 i). Forewings with yellow-white ground densely sprinkled with black. Antemedian 
area pure white; posterior to the inner line and in front of the whitish subterminal or over the entire marg¬ 
inal area a reddish brown dusting; the black dentate transverse lines have white edges on the sides remote 
from one another; the two upper stigmata are large with black centres and edges, also the claviform stigma is 
faintly marked with black. Fringes white and black mixed. Hindwings brownish grey, duskier in marginal area 
with discal lunule and transverse line beyond, on the margin black streaks that are whitish inwardly. Fringes 
yellow-white. Alexander Mountains. 
Oe. lithoplasta Hmps. (2 k) is similar, paler, forewings whitish, more faintly sprinkled with black and 
scarcely tinged with ochreous; both upper stigmata white with faint black outline, the round orbicular stigma 
with ochreous centre, reniform stigma with brown longitudinal line near its inner edge; the elbowed is double 
but only the inner line is black and distinct, the outer one more diffuse; behind the white subterminal line, 
the marginal area is adumbrated. Hindwings pale brownish grey with faint discal streak, outer transverse line 
and subterminal shade. Fringes white. W. Turkestan (Tashkend); Ili territory.
