almost devoid of markings and pale grey. The stigmata are indicated only by paler patches. All these forms 
are described from central Italy, but they also occur elsewhere. 
71. Genus: Atlietis Hbn. 
This Genus does not yet seem to be clearly defined and Warren made a number of wrong classifica¬ 
tions and errors in the Main Volume. A few of the groups have been investigated in the meanwhile and their 
position is now clearer. Nordstrom, Filipjev and others are working at the subject and it is to be anticipated 
that shortly a clear survey will be possible. Unfortunately this will not be in time to be incorporated in this 
work, although possibly something may be said in the Addenda. For the moment in general w r e will follow 
Warren’s secpience, so as to facilitate comparison with the Main Volume. Filipjev indicates a definite dis¬ 
tinction between the Genera Athetis and Proxenus (with Radinogoes as sub-genus), in pointing out that the 
Athetis £have a well developed uncus, whilst this is completely absent in Proxenus. After recognition of this 
fact certain re-classifications naturally become necessary. 
A. conspicua Leech (Vol. 3, p. 208, pi. 48 a) — grisescens Braes, is a greyer shade, the stigmata are grisescens. 
not black, but grey-brown. Omi-hsien (Szechuan). 
A. lapidea Wilem. Forewings pale grey-brown with rosy hue. Anterior transverse line blackish and lapidea. 
irregular, angulated inwards below the centre, the posterior line is dentate, blackish. Stigmata are absent, 
only a black discal spot is present and a row of black dots at outer margin. A dark central shade and a sub¬ 
terminal line are discernible as vestiges. Hindwings grey-brown. The $ has narrower wings and more distinct 
central shade and subterminal line. Wing expanse: 27 mm. Hondo, Yoshima, Kobe in August. 
A. furvula Hbn. ( lenta Tr.) (Vol. 3, p. 208, pi. 42 g, h) having no uncus in genitalia, would appear furvula. 
to belong to Proxenus and is now dealt with in that Genus. It should however be remarked here that it would 
appear better to re-introduce the name: — lenta Tr. for this species. English authors (Turner) in particular lenta. 
are in favour of this, as furvida might be intended to denote a melanic form of Acosmetica caliginosa Hbn., 
the illustration and the description could only be taken to apply to this species. 
A. alsines Brahm (Vol. 3, p. 208, pi. 42 h) — levis Stgr. according to Boursin is a separate species, levis. 
that has no connection with alsines. It does not occur in Asia Minor or in Spain, but only in Ferghana, Margelan. 
A. pfeifferi Bours. reminds one most of alsines, but differs by the wider more yellowish forewings; 'pfeifferi. 
the markings appear softer. The central shade is broad and distinct and sharply bent inwards. Claviform stigma 
is absent, both upper stigmata large but not very prominent. The posterior transverse line is a simple fine 
black line (not consisting of arcs); the space anterior to the very distinct subterminal line is darkened, the 
marginal area itself is paler than the rest of the wing. Hindwings yellowish with dusky margin. Wing expanse: 
32—34 mm. Lebanon. 
A. straminea Zerny (21 c) is very close to pfeifferi Bours. Forewings are still wider and a more vivid straminea. 
straw-yellow. Transverse lines are blackish, the subbasal bent in a rightangle, the two central lines indicated 
by distinct black dots on veins. The most striking feature is the very distinct wide dark central shade, that 
proceeds close to the reniform stigma or even traverses same, forming an obtuse angle below' the lower angle 
of cell and having fine dentations on the veins. Orbicular stigma often indistinct and small, without definite 
outline, only a dusky centre visible. Reniform stigma large, constricted in centre. Hindwings grey-brown 
with stiaw-yellow' fringes. On underside disc of forewings heavily blackened. High Atlas (Tachdirt), Morocco. 
A. alsinides Costni. is unknown to me and would seem a doubtful species. It is said to stand in rela- alsinides. 
tionship to alsines (Vol. 3, p. 208, pi. 42 h) as superstes does to taraxaci. It is very similar to alsines, but of 
much wider wing contour with much larger cell stigmata, both veiy bold and clearly marked, with blaek- 
brow r n centres, orbicular stigma round. Monte Gibbio, Sestola, in June—-July. 
A. blanda Schiff. (Vol. 3, p. 208, pi. 42 h) — arcuata Vorbr. has a distinct arched rov r of black dots arcuata.

specimens with darker purer grey forewings and paler hindwings that are only faintly duskier at margin. 
Underside also is distinctly paler. 
A. corticea Hmps. should be classified after blanda. Head and thorax are rufous, frons whitish, palpi corticea. 
black with whitish tip. Forewings rufous with darker interspersions, somewhat paler towards base. Both 
transverse lines blackish, undulate, the anterior line angidated inwards on 1, the posterior line incurved on 
discal fold. Orbicular stigma is a black dot, reniform.stigma very indistinctly black. From the lower angle
