26. Genus: Lasionycta Auriv. 
L. hospita A.B.-H. (= ardua Filipjev) (15 c). Forewings grey-black with interspersions of whitish hospi.ia. 
hairs and scales. The slightly dentate transverse lines blackish, not very pronounced, the discal area between 
them only somewhat darker. A black longitudinal streak on the submedian nervure more or less distinctly 
conjoins the two lines. Frequently the space below same to the inner margin is somewhat heavily darkened, 
Subterminal line faintly indicated by a row of dots. Stigmata can only just be discerned. Fringes with blackish 
checks. Hindwings grey-white with faintly darker wide marginal band, discal spot and central line posterior 
to same. Sajan territory. 
27. Genus: fiiuiiiht Stgr. 
H. tancrei Graes. (Voh 3, p. 36, pi. 21 d). The illustration was much too dark grey-brown, the species 
is much more whitish. We are able to give a good illustration of — graeseri Pglr. (15 c). graeseri . 
H. nefasta Pglr. (15 d) most resembles turpis, but it has less acutely pointed, more brownish and dis- nefasla. 
t-inctly marked forewings. Markings are pale buff and grey-black. The inner transverse line is almost vertical, 
the outer one extends first sharply outwards, but from reniform stigma it proceeds almost parallel to outer 
margin down to the inner margin. The brownish white stigmata are large, orbicular round, reniform with dark 
circumscription. The pale subterminal line has an inner blackish edge. Hindwings grey-black with dark central 
band. Posterior to same the wing is paler and fringes are light. Lob-nor. 
H. sabuloruni Alph. (Vol. 3, p. 86, pi. 21 e). The illustration is much too grey-brown and markings sabulorum. 
too varied. A better reproduction is made here (15 d). — distincta Stgr. A good illustration is being given distincta. 
(15 d). - expressa ( 0. B.-H. i. 1.) n. f. (15 d) is a much paler, somewhat smaller and more distinctly marked expressci. 
form from the Karagai-tao (central Asia). 
H. orbona A.B.-H. (15 d) is classified by the author after sabulorum. Forewings whitish ochreous orbo'na. 
yellow with rusty brown mottlings and admixture. Markings rusty brown. Inner transverse line punctiform, 
the outer one sharply dentate with pale outer edge. Between same, an irregular red-brown central shade. Stig¬ 
mata practically indiscernible, also subterminal line practically invisible. Hindwings paler than forewings. 
Karagai-tao. 
H. contempta Pglr. (15 e). Forewings grey-white with brownish tinge. Blackish double subbasal. contempia. 
Anterior transverse line double, the posterior is simple with white outer edge. Stigmata with dark surrounds, the 
large reniform whitish at lower outer angle. The whitish subterminal line is sharply dentate with darker inner 
edge, generally it is dissolved into separate small spots. The dark marginal line expands at extremities of veins. 
Fringes yellow-grey with darker dividing line and checked tips. Hindwings darker grey than forewings with 
whitish fringes and pale streaked inner marginal area. In the $ the subterminal line is more complete. E. 
Turkestan, Aksu. 
H. stoliczkana Moore (15 e) was omitted from Main Volume. It is sleeker than sabulorum, with oblique stoliczkana. 
outer margin to forewings, darker grey-brown, more smoothly scaled and somewhat less distinctly marked. 
Both transverse lines are practically extinct. Subterminal line is somewhat more undulate and more clearly 
visible than in sabulorum. Hindwings darker grey-brown. East Turkestan (Chamil Hami). 
H. zetina Stgr. (Vol. 3, p. 177) (15 e) is neither a form of zeta , nor is it a Crymodes, but should be inserted zetina. 
here after insolita. Forewings are more elongate and narrower with more oblique outer margin, dusted with 
yellowish grey-brown. The very straight subterminal line is characteristic; it consists of fine dentiform marks 
with pale yellowish outer edges. Other markings as in insolita. Hindwings however darker than same, fringes 
inclined to whitish only outwardly, not nearly such a pure white as in insolita. Aksu, Altyn-Tag. As a synonym 
we must mention impia Pglr. (Vol. 3, p. 86, pi. 20 f) which should therefore be deleted as a separate species. 
H. griseola Rothsch. (15 e) is a remarkable species, that resembles a Thargelia. It is very large, with griseola. 
narrow wings, yellowish white ground colour and grey and delicate black markings, veins finely black. Basal 
streak and the 3 stigmata as in Tlx. gigantea. Posterior to cell there is a pale oblique streak to margin below 
apex. In place of subterminal line there are blackish sagittate streaks, that extend to margin in paler grey. 
Hindwings white with veins outlined in brownish grey. — ab. rosacea Rothsch. is a reddish suffused form, rosacea. 
Algeria, occurring in February and March. (S. Biskra, Mraier, Ouargla, El Golea, Touggurt). 
H. pulverata A.B.-H. (= cinnamomeogrisea Rothsch.) (15c) somewhat resembles sabulorum. Fore- pulverata. 
wings grey-white with yellowish admixture, finely mottled with black, transverse lines faint. The small orbi¬ 
cular stigma is white, as also is the reniform which has blackish striations in centre. Claviform stigma has a 
distinct black circumscription. The subterminal line consists of whitish spots and is irregular with very in¬ 
distinct “W". On margin there are small black lunules; fringes whitish. Hindwings somewhat paler with 
grey-black, narrow, straight marginal band and blackish discal spot. Tunisia and Algeria.
