species. Our illustration (Vol. 2, p. 425, pi. 55 1) represents niloticus. The latter is recognisable by the much 
fainter striations of forewings, in basal area besides they are quite absent; hindwings on upper and undersides 
are almost completely or nearly devoid of markings. Apart from the bold main lines henleyi has a denser net¬ 
work of finer lines. Also on hindwings there are distinct reticular lines. On underside the costa of hindwings 
is blackish. In frater the forewings are irregularly covered with fainter and distincter black striations. In the 
$ especially there is a bolder line behind the cell (somewhat as is shown in the illustration of co.ssus S in Vol. 2, 
pi. 52 b). The ground colour is ashy grey with yellowish tone. Hindwings of and $ are devoid of markings. 
30—45 mm. Sanaa (Arabia), presumably also extending into palaearctic territory. 
7. Genus: Dyspessa Him. 
D. ulula Bkh. (Vol. 2, p. 426, pi. 52 k). — pallida Rothsch. is described: The white spots much more pallida. 
extensive and diffuse. Sometimes the ground colour is quite suffused with white. The ? on the other hand 
is as dark as infuscata Stgr. Algeria. Whether pallida differs from the species dealt with in Vol. 2, p. 426, pi. 52 k 
as pallidata Stgr., cannot be discerned from the description. The following two forms: marmorata and alge- 
riensis are now held to be separate species. 
D. mgrmorata Rmb. (Vol. 2, p. 426). The subform niaroccana Rothsch. is to be added. It is much darker maroccana. 
brown than type. The pale patches are almost entirely restricted to the margin and near same. The $ is also 
darker and the white patches smaller. Morocco. — nigrita Wagner in consequence of its size, is clearly to be nigrita. 
classified with marmorata Rmb. Forewings and thorax pure white with very bold markings. Hindwings and 
abdomen blackish. On underside all wings are black, but the costa of hindwings is whitish. Also the legs and the 
underside of the entire body are white. Anatolia. A very similar specimen, as far as the upperside is concerned, 
is placed under ulula in the Ptjngeler collection. It was captured at Digne.However the underside is also pale. 
D. algeriensis Rmb. (Vol. 2, p. 426). — cypriaca Rbl. from Cyprus differs from algeriensis by the com- cypriaca. 
plete absence of all white markings except in the middle cell of forewings and by the fringes which are devoid 
of checks. In the Pungeler collection there are 1 <$ and 2 of algeriensis. The description given of cypriaca 
would also apply to these, except that one of the $ has fringes with checks, infuscata Stgr. from Pontus, accord¬ 
ing to a pair in the same collection, has a faint pale patch at two-thirds the length of costa. To what degree 
the species and forms mentioned here can claim specific rank, is at the moment more or less a matter of per¬ 
sonal opinfon. Perhaps with the exception of marmorata, the series of ulula, algeriensis etc. in the Pungeler 
collection embrace specimens under one and the same denomination that are of totally different appearance, 
whilst often specimens under different separate classifications are so alike that they can scarcely be differen¬ 
tiated. — It would seem therefore, as if only a careful examination of the genitalia of a large number of speci¬ 
mens of the various forms and species of the ulula group, together with exact data as to the areas of their 
distribution and occurrence will bring satisfactory elucidation as to their specific grouping. It would for in¬ 
stance appear quite possible that the specimen from Digne mentioned under nigrita of ulula, may actually be 
nigrita, but at the moment this cannot be definitely asserted. 
D. hethitica Dan. Similar to pallidata Stgr. (Vol. 2, p. 426, pi. 52 k) but larger, 27—37 mm. The dark hcthitica. 
markings of forewings are more inclined to be dark grey than brown. The cell is white, standing out promi¬ 
nently; the costa also is white in the basal two-thirds. Hindwings pure white with dark veins. In the $ the 
hindwings are somewhat darker. Marash. — Also kurdistana (Vol. 2, p. 451) is similar to pallidata. The author 
should have been stated as Turati (not Bang-Haas) who had illustrated same in Nat. Sicil. 21, pi. 6, Fig. 28. 
D. turbinans Trti. The denomination has been made owing to its mannerism when attracted to light, turbinans. 
Other species of this Genus when attracted to a lamp settle on the sheet and crawl around, turbinans rest¬ 
lessly encircles the lamp. In other respects turbinans differs from kabylaria B.-Haas (which was rather too 
grey in colour in the illustration in Vol. 2, pi. 52 k) by dark spots on forewings near the fringes and a some¬ 
what paler marginal area. Nevertheless the dark spots near the fringes also in kabylaria extend to the outer 
one-third of costa, although this is not distinctly shown in the illustration. The dark patch on inner margin 
with its pale surroundings as shown in our illustration of kabylaria is very distinctive and well executed. £ 
18—24 mm. Cyrenaica. 
D. cyrenaica Trti. Compared by the author to nigritula Stgr. and minima B.-Haas (Vol. 2, p. 427, cyrenaica. 
pi. 52 k) and established from a single $. All wings blackish brown with slight violet sheen being also trans¬ 
parent. Costa of forewings finely yellowish, this however does not extend as far as the apex. At close of cell 
there is a faint yellow patch and a black dot. According to the illustration in Vol. 2, pi. 52 k, minima is consi¬ 
derably paler. One might assume that cyrenaica is actually a small specimen of algeriensis. Cyrenaica, 
D. jordana Stgr. (Vol. 2, p. 427, pi. 55 1). Large specimens (37 mm) are denominated maxima Trti. maxima. 
These are typical of Cyrenaica, but a $ in the Pungeler collection is equally large, agilis-magna is only a 
trifle smaller. 
D. emilia Stgr. The $ has already been described and illustrated, see Vol. 2, p. 426, pi. 52 k. One Q of emilia. 
the species in the Pungeler collection somewhat resembles roborowskii (Vol. 2, pi. 52 i) in colour of body and 
forewings, but the hindwings of emilia ^ are faintly brownish. On forewings the dark median band is absent.
