over Algeria, Tunisia to Egypt. —- ferrantei Drt. (20 c) is a very pale sandy yellow desert form from Egypt, ferrantel. 
23a. Genus: Oiaflochia Pglr. 
Proboscis developed; palpi medium long, straightly porrect with pendant last segment and long hairy 
central section. Frons with short conical projecting process in centre. Antennae with short cilia. Head and 
thorax with smooth hairs, no tufts. Fore tibiae with a short claw. Only 2 species: 
Generic type: D.saca Pglr. 
D. saca Pglr. (20 d). Forewings pointed with oblique outer margin, ashen grey, no transverse markings, saca. 
with indistinct stigmata. The small orbicular stigma extended to a point towards margin. Reniform stigma 
of usual shape with darker centre. Claviform stigma long and narrow. The veins have dainty darker streaks 
in marginal area. Hindwings in pure white with a few grey scales and darker veins in marginal area; in $ 
they are more heavily dusted with grey. The species resembles Scyth. scripturosa but is easily distinguishable 
by the more pointed forewings and purer grey colour and absence of all transverse markings. Wing expanse: 
33 mm. Syr-Darja (Baigacum), September. 
D. esurialis Pglr. (20 d) is very close to the preceding species, but has less pointed wings with rather esuriulis. 
more undulate margin. Claviform stigma is absent, reniform is larger and generally markings are more definite. 
There is a posterior transverse line of paler lunules and an irregularly sinuate subterminal line. Hindwings 
with distinct marginal line and on underside with a decided black central spot, which is not present in saca. 
Syr-Darja (Baigacum), September. 
23b. Genus: Anataelia Drt. 
This Genus differs from Scythocentropus by the second segment of palpi which is not scaled, but has 
a long beard-like brush of hair. Antennae of with pyramidal serrations and long fascicles of cilia. Thorax 
covered with single hairy scales; triangular tuft anteriorly. Abdomen with crests. Fore tibiae with bold spur 
on outer side. Neuration as in preceding Genus. Only 1 species: 
A. orotavae Drt. (20 c). A large species. Forewings ochreous yellow, peppered with brownish having orotavae. 
fuscous central area and black basal streak. Transverse lines double, a white dot each on median and sub¬ 
median nervures before the anterior line. The posterior line undulate and dentate, the veins beyond same 
dusted with black and white. Orbicular stigma small, oblique, elliptical, pale brown; reniform quadrate, white 
with black surround. Subterminal line pale with brown sagittate spots anteriorly, marginal area outwardly 
black-brown, except for the pale apex. Hindwings grey-brown. Teneriffe (Orotava). 
25. Genus: Pseudopseustis Pimps. 
P. tellieri Luc. (Vol. 3, p. 182) (20 d). We are now able to illustrate this species. As synonyms are to tdlieri. 
be added: pieretti Culot nec Bugn. (Heliophobusl) and diacrisioides Rothsch. (Harpagophanal). It occurs also in 
Algeria (Guelt es Stel and El Mesrane) in October, November. 
25a. Genus: •laxartfa Pglr. 
This is meanwhile classified next to Pseudohadena, but has completely stunted proboscis. The medium 
short palpi are densely haired, projecting straight forward with pendant last segment. Frons without pro¬ 
jection. Antennae of d with long pectinations to tip; of 9 with delicate short bristles. Head and thorax densely 
haired, without tufts. Fore tibiae without claw, the first section of fore tarsi with 8 horny hooks. Abdomen 
extended, stumpy in 9 and without crests. Only 1 species: 
J. elinguis Pglr. (20 d). The whitish forewings are coarsely bestrewn with brownish grey. Anterior elinguis. 
transverse line uniformly sinuate with somewhat paler inner edge. Posterior line with pointed dentations, 
parallel to margin, outwardly there is a pale, similarly dentate band with a dark edge. Stigmata somewhat 
paler, rather small and indistinct. Hindwings brownish white, dusted with grey, with faint central spot and 
grey arched line and somewhat dusky marginal area. Syr-Darja (Baigacum), September. 
26. Genus: Pseudolaadena Alph. 
P. laciniosa Chr. (Vol. 3, p. 182, pi. 41 1). The illustration was not good, a better one is given here (20 d). laciniosa. 
Fritz Wagner has captured this species in Asia Minor (Akshehir) and this is probably the western boundary 
of its distribution. 
P. impedita Chr. (20 d) was omitted from Main Volume. It is close to presbytis Pimps. (Vol. 3, p. 183, impedita. 
pi. 43 a) but larger and with a more reddish tone. The posterior transverse line is extinct, the stigmata smaller
