Subgenus: Powellinia Obth. 
Type: P. lasserrei Obth. 
P. matritensis Vasq. (Vol. 3, p. 24). This species was not illustrated in the Main Volume and an 
illustration is now being given (6 f); matritensis has meanwhile been frequently found in various localities 
in Spain. 
P. messaouda Obth. (Vol. 3, p. 36, pi. 7 i) is often held to be the north African form of matritensis , 
however Corti seems to have considered same to be a genuine species. It is larger, has a slightly different 
wing contour, especially the wings are wider, the colour more generously mixed with yellow-red. As the 
illustration in the Main Volume by no means represents the species, we are giving a good illustration (6i). 
Distributed over Algeria and Morocco. 
P. noctanibulatrix Chret. (6 i) is very close to the preceding species, but the wings are narrower, of 
bluish grey with admixture of more or less darker shadings, brown in cell and on the fold mixed with 
ochreous, with widely brownish costal band up to apex, median and submedian nervines white; the anterior 
transverse line is yellowish, the posterior one is only indicated; subterminal distinct white or yellowish, wdth 
brown sagittate marks beyond same; stigmata small, yellowish, an ochreous spot behind the reniform stigma; 
claviform stigma long, ochreous with black circumscription; fringes checked with brown. Hindwdngs wdiite, 
brownish towards margin. The $ has much shorter wings, somewhat like faticlica, but the transverse lines are 
distinct. Cfafsa (Tunis). The larva is dorsally whitish or pale grey, ventrally more greenish wdth white 
lines, spotted on dorsum. It lives hidden in the sand on Astragalus gombo, Lithospermum, Echinops. Pupation 
in a frail cocoon, the imagines emerge after 3 weeks in August, September. 
P. pieretti Bugn. ( = marsdeni Bak.) (Vol. 3, p. 24, pi. 12 e). The illustration in Main Volume leaves 
a lot to be desired and we are giving a fresh illustration (6 h). The species is much smaller than the prece¬ 
ding one. 
P. lasserrei Obth. ( = sabura Mab.) (Vol. 3, p. 24, pi. 5 b). On account of the rather poor illustration 
in the Main Volume, a better illustration is now; given here (6 h). The species is easily distinguishable and 
occurs everywhere commonly along the north African coast from Morocco to Egypt. Latterly it has been dis¬ 
covered in Spain (I have before me a specimen from Tarragona) and in Syria (Marash) and Palestine. — 
ptolemaida Trti. is a darker grey form from Cyrenaica. - unctus Chr. The reference to the plate should be 
12 d instead of 18 a as stated in Index. The illustration is scarcely recognisable! 
P. orana Luc. (Vol. 3, p. 118, pi. 28 c). In the Main Volume this was still classified under the Genus 
Leucochlaena, but would probably be more correctly placed here. The illustration was copied from a bad 
drawing and we are giving a good picture here (6 i). In the pale yellowish grey colouration this small species 
readily classifies itself in this group, as the markings are very similar. Transverse lines are very faint. Only 
known from Algeria and Morocco. Oberthur considers that noctambulatrix is a dark form of same, but this 
does not appear to be correct. 
Subgenus: Cladocerotis Hmps. 
As was indicated on p. 249 of the Main Volume all the species grouped in this Genus belong without 
a doubt in closest relationship to the Powellinia. Frons very distinct with its prominent three-pointed pro¬ 
jecting process. 
Type: C. optabilis B. 
C. ankarensis Rbl. (11 a) originally described as an Episema, but no doubt belonging here. The densely 
woolly haired thorax is grey-white, forewings pale brownish grey, in some specimens purer pale grey with 
indistinct transverse lines, the posterior one distinctly dentate, at end of cell a grey diffuse reniform stigma 
mark; slightly darker towards the margin, wherein a somewhat paler dentate subterminal line shows up, having 
a rather darker inward edge; on margin small black dots in the interstices between the veins, fringes pale 
with 2 dark dividing lines. Hindwings thinly scaled, white with dark lunular mark at upper angle of cell, 
marginally sparsely bestrewn with brownish and with dark marginal dots. From the neigbourhood of Angora, 
also from Anatolia, therefore certainly more widely distributed than at present known. Captured in October. 
C„ wichgrafi Corti i. 1. (11 a). As according to Corti the genitalia are quite different to the preced¬ 
ing species, this may be a genuine species. It is smaller, more yellow-grey, also the thorax; transverse 
lines more distinctly dentate, only a narrow shade indicates the reniform stigma, but the space posterior 
to same to the post median line is dark and this also is darker between veins 4 and 6; marginal dots scarce¬ 
ly visible. Fringes darker brown. Hindwings dusky yellowish. According to 1 $ from Alishar (Asia Minor). 
October. 
C. benigna Corti (11 a) is larger than the two preceding species and wings are more elongate. Pale sandy 
brownish with coarse black speckles, distinct, somewhat dentate transverse lines and stigmata, also clavi¬ 
form stigma blackish and present. Hindwings whitish with very delicate brownish marginal line. Askhabad.
