towards the costa. The underside is yellowish white without any dusky dusting. Vertex, basal limbs, palpi 
and back of thorax pure white; frons, 2nd and 3rd segments of palpi, legs and abdomen pale straw-yellow, fore 
tibiae grey on inner sides, fore and middle tarsi ringed with grey. Length of forewings 15 mm. From the Inn 
Shan, Chingan mountains, eastern Mongolia, at an altitude of 2000 m. In July. 
124b. Genus: Crosia Dupont. 
Proboscis weak; palpi short, somewhat oblique, the central segment scaled on underside, with short 
terminal segment. Frons with flat quadrangular corneous plate with small central point. Antennae of q finely 
ciliate. Thorax scaled, abdomen without crests. Fore tibiae without spines. Apex of forewdngs pointed. On 
hindwings 3 -f 4 and 6+7 are stalked. Only one species: 
C. hachem Dupont. Forewings very pale brownish on upperside. Transverse lines paler than ground 
colour, the posterior one is finely dentate, between them there is a straight central shade. Subterminal line 
is similarly pale, regular, it interrupts the brown veins. The large orbicular stigma and the narrow reniform 
stigma are both paler than the ground colour, the former with black circumscription, elliptical at top. Be¬ 
tween the tw r o stigmata the ground is black, as in c-nigrum. Hindwings grey-whitish. Wing expanse: 21 mm. 
Only 1 $ from Oran, captured in October. 
125. Genus: Megalodes 
M. prolixa Drt. (22 g) resembles eximia Frr. (Vol. 3, p. 242, pi. 48 i) but the ground colour is a pale 
olive-grey, not green. Basal area on the submedian fold and the postmedian area suffused with red. The white 
transverse lines are double as wide as in eximia , the central area enclosed by them is narrower and somewhat 
darker than the rest of the wing, especially in the innermarginal half. The stigmata are only faintly outlined 
by white. Veins in marginal area pale whitish. Hindwings light grey with 2 whitish transverse lines. Palestine 
in April and May. 
M. gloriosa Stgr. (Vol. 3, p. 242, pi. 48 i), liturata Clir. and kashmirensis Hmps. (Vol. 3, p. 243, pi. 48 k) 
should be removed and classified as Cucullianae. In this Supplementary Volume they are dealt with on p. 128. 
127a. Genus: Prolomeceras Rbl. 
The only species was described by Oberthur as “Cimelia” , but according to Rebel’s researches, it 
is a quadrifinid Noctuid closely related to Megalodes. It w r as omitted from Main Volume. The d antennae are 
pectinate. Frons with a bold naked chitinous spine in centre, with 2 shorter spines laterally. Eyes small, palpi 
almost as long as diameter of eyes. Thorax scaled with coarse hairs, abdomen sleek, long and smoothly scaled. 
Forewings wide with boldly bulging margin. Neuration as in Megalodes, but veins 8 + 9 on forewings with 
shorter stalk. Only one species: 
P. mimicaria Obth. (23 d). Forewings ochreous to earthy brown, with veins finely marked in white, 
rather more boldly before the postmedian. The double transverse lines are intertilled with white, extending 
from black double spots on costa. Stigmata finely outlined by white, the orbicular with a longish appendix 
at lower end, which extends beyond the claviform stigma. Posterior to the whitish subterminal line there is 
a white and black dentate marginal line. Fringes boldly checked, black and white. Hindwings brown with 
double darker discal streak, an undulate, curved pale postmedian and widely darkened marginal area, therein 
a dentate paler subterminal line and faintly checked fringes. Algeria (Sebdou, Lambessa) in September. The 
ova are brown when laid turning to leaden grey. The young larva has a stunted front pair of abdominal legs. 
Head is black, body dark grey with wide white dorsal and orange lateral spots, underside is black-brown. 
They fed on grass, but only survived two moults. 
127b. Genus: Mesaegle Dumont, 
Proboscis quite rudimentary, palpi very short and appressed to frons. The frons with a bold process 
in the shape of a laterally compressed cylinder, which is deeply hollowed out on top. Antennae also in $ weakly 
lamellate and ciliate. Thorax covered with hairs, mesothorax with wide flat scales below the hairs, no tufts 
on thorax or abdomen. Fore tibiae with a long chitinous spine anteriorly, outwardly. Forewings with some¬ 
what concave costa, apex rounded, margin oblique, about as long as the inner margin. Only 1 species: 
M. gouzzakottli Dumont, (22 g). Forewings pale brownish olive, the margins white, a wide submedian 
longitudinal streak, a large trilobed spot at end of cell, an oblique apical streak and a wide, outwardly concave 
submarginal band between veins 1—7, all white. The veins and a black marginal line are somewhat darker 
brown than the ground. Fringes white. Hindwings of $ densely peppered with brown on white ground, with 
a white spot on margin between veins 2—5. Fringes white beyond the dark brown marginal line. Algeria (El 
Golea) in April. We are able to illustrate a $ cotype *). 
*) According to subsequent information, Hours in states that this Genus belongs to the Noctuinae (Quadrifinae).
