ation; lines brown, arising from costal spots and formed much as in ludovicaria and uni calcar ala, the antemedian 
macular, with threaddike connections, the median on the forewing bending round the outside of the cel 1 - 
dot; subterminal line forming 2 large spots, radial and subtornal, only the latter well developed on the hind¬ 
wing. Barce, Cyrenaica, 10 September 1934.

1934. Slightly larger (“20 mm'"), rhe ground-colour more powdered with black, the black cell-dot of the hind¬ 
wing obsolescent, the pale spots of the subterminal less salient, the postmedian black dots less sharply defined, 
the median shade perhaps more oblique (so that a comparison with obliquaria Trti. is possible). In spite of 
these divergences, it does not seem to me impossible that this and bimaculata are sexes of one variable species. 
p. 53, to S. completa Stgr. Sterneck adds to Wehrli’s differentiation of this from intermedia that complete. 
the armature of the aedoeagus shows significant distinctions. It is somewhat doubtful whether the biological 
account given in Vol. 4 (p. 131) really refers to the present species; perhaps Chretien himself was doubtful, 
as he gives a new description in 1917 (as completa) and makes comparisens with rusticata and filicata, without 
mentioning intermedia. Egg a short ellipsoid, compressed laterally; depressions irregular, very narrow, ar¬ 
ranged in longitudinal lines; cream white, not spotted with red. Adult larva shaped as in rusticata and filicata; 
skin rugose, folded, granulated; dorsally earth-grey, laterally yellowish, with a fleshy tint on the last seg¬ 
ments; segmental incisions black-brown, accompanied on each side, near the spiracles, by a large black spot; 
a pale lozenge dorsally on the “8th segment"; lines indistinct. Head small, slightly bifid, the lobes conical, 
reddish brown. Like its relatives, it thrives on detritus of dead leaves. 
p. 54, to S. vulpinaria H.-Sch. There is a most astonishing record, under the name of rusticata by which vulpinaria. 
it is usually known in Britain, that "-his is extremely common on the island of St. Ivilda; see C. Gordon Hewitt, 
Ann. Scot. Nat. Hist. 1907, p. 220. I can offer no suggestion as to the probable means of its introduction there.

a faint rosy tinge that it is hard to reconcile with any possible form of muricata.

S. exilaria Guen. (Vol. 4, pi. 4 a, as filacearia; 4 c) esterelata Mill. Homberg (in Lhomme, Cat. Lep. exilaria. 
France, p. 582) considers this to be a separable race, not a synonym as cited in Vol. 4 (p. 104): wings more esterelata.

the late Dr. L. Muller (Mitt. Miinchn. Ent. Ges., Vol. 26), in which he deals exhaustively with the known 
distribution and variation, besides some interesting facts and speculations regarding the ecology, heredity 
and other problems. Particularly arresting is the fact that the Mendelian inheritance in the British race seems 
to be the reverse of that in the Wachau race: the dark form dominant in the former (Mr. W. Buckley's experi¬ 
ments), recessive in the latter. The name-typical race, as at present understood, belongs chiefly to the Alps,

blame Dr. Muller for erecting this name before that of austriae, but as it is preoccupied in Sterrha it can¬ 
not be substituted for austriae. — ab. bellieri nom. nov. (= grisescens L. Mull., nec Culot) is founded on the $ bellieri.
