STERRHA. By L. B. Prout. 55 
S. charitata Rbl. Antenna of 8 shortly ciliated, its hindleg without spurs, the tarsus not abbreviated, eharitaia. 
anal tuft unusually long. Length of a forewing 6—8 mm. Vertex light yellow. Wings ochre-yellow with reddish 
brown irroration and markings, both wings with small black cell-dot; forewing with 4, hindwing with 3 waved 
lines; an interrupted dark terminal line and black-brown dots on the base of the fringes. Both wings with the 
termen somewhat sinuate. Tenerife, the type collected in April. 
8. subsaturata Guen. ab. lecerfiata Homberg (Vol. 4, pi. 3 f). Culot lias described and figured this tecerfiala. 
frequent Algerian form, which occurs also in Spain and Tunis, under the synonym of holli Oberth. (M. S.). Ashe 
only knew typical subsaturata from Frairce (Cette and Sainte-Baume), he assumed — on the strength of a single 
example — that lecerfiata (= holli) was the Algerian race. 
S. protrusa Trti. (6 i). Very distinct in its shape (which begins faintly to foreshadow that of emarginata ) proirusu 
and in its large, somewhat Cosymbiid cell-spots. $ antennal ciliation short, hindtibia thickening distally, a 
hair-pencil from near base, tarsus very short. Lines obsolescent, the postmedian on both wings just traceable, 
above and beneath arising from a strong reddish costal mark. Derna, Oyrenaica, the figured type collected 
on 2 October. The areole of the forewing is open, the 1st subcostal entirely failing to anastomose with the others; 
the 2nd subcostal and 1st radial of the hindwing are stalked for almost half their length. 
8. subrufaria Stgr. ab. fusaria Chret. is a dwarfed form (measuring “8—10 nun instead of 14—-16’'), fusaria. 
of a much lighter colour and more uniform, the forewing with 2 distinct brown lines, arising from a dark 
brown costal spot, the hindwing with 1 line. — The Tring Museum possesses an enormous series of subrufaria 
(or fractilineata) from N. Africa, extending from Morocco to Cyrenaica, and I am still unable to separate them 
into two species or to differentiate the more warmly coloured and weakly marked of them from the typical 
fractilineata of Italy and Sicily. In deference to Chretien’s treatment of it, and in the absence of biological 
data regarding the European form, I am using the name subrufaria and add a brief abstract of his account 
of the life-history. Egg a broad, short ellipsoid, with the depressions polygonal at the poles, long-oval on the 
sides; slightly greenish white, changing to yellowish. The larvae grow very irregularly, some maturing in 5 
or 6 weeks, others in 3 or 4 months, others hibernating; they have nearly the form of rusticata, filicata, etc., 
but are less stout; head black, body much folded, rugose, finely granulated,.dirty yellowish grey, with vague 
lozenge-shaped markings, the ordinary lines indistinct; setae short, claviform. They prefer fresh leaves and 
are sometimes cannibalistic. Pupa yellowish brown, finely shagreened; stigmata large, rather prominent; 
cremaster reddish brown, broadened at the base, narrowing rapidly, the small terminal cone bearing only 4 
hooked setae, two in the middle, one on either side. 
S. lobaria Chret. (= balestraria D. Luc.) (5 i). These two names, published almost simultaneously, lobaria. 
refer to one and the same species; lobaria has 23 days’ priority. The “pectinate" antenna is, as I surmised 
(Vol. 4, p. 104), dentate-fasciculate. I have before me a long series from Ain Sefra (Oran), and a few from 
Biskra and Tozeur and have recently seen one from Ghor-el-Safieh, at the S. end of the Dead Sea. Scarcely 
variable. 
S. subpurpurata Stgr. (Vol. 4, pi. 3 f). Turati has recorded a $ from Berea, Cyrenaica, collected on subpurpu- 
25 October. ‘ rota 
S. sanctaria Stgr. is believed to show some geographical variation, although it is not impossible that sanctaria-. 
a study of more extensive material than has yet been brought together may show that all the forms occur in 
the same area. The long cell of the fcrewing and the extremely long stalk of the 2nd subcostal of the hindwing 
are characteristic of all the forms, unless possibly the former is slightly less extreme in the two known examples 
of outayana. — outayana Wehrli (= affinitata Culot, nec B.-Haas) (6b) is differentiated by the less incomplete, outayana. 
more dentate postmedian line of the forewing, more sharply dentate postmedian of the hindwing and broader 
dark basal area of the latter wing; to some extent, also, the dark scaling of the forewing is stronger at the 
base than in the other forms and the costal spot beyond the cell-dot better developed. El Outaya, Constantine, 
2 <$<$. • —- transcatenulata Rothsch. (Vol. 16, pi. 7 k), erected as a separate species and so treated in Vol. 16 of transcate- 
this work (p. 7 8), is still closer to name-typical sanctaria. Perhaps a trifle narrower-'w'inged, the proximal subterminal 
shade of the forewing fairly strong or at least indicated; the proximal black irroration is feeble on the hind¬ 
wing, scarcely traceable to the base, while on the forewing it is only found between the two closely approxim¬ 
ated lines and even here is sometimes slight, transcatenulata, however, like sanctaria, is certainly variable. 
Sahara: Tahihout, Ti-n-tabarik and Rharis. — crassisquama Warr. & N. C. Rothsch. (Vol. 16, p. 78, pi. 8 1), founded crassisqua- 
on a single $ from the Egyptian Sudan, is very likely also an extreme form of sanctaria, the ground-colour not 
quite so bright and with the irroration so heavy as to leave little of it visible; two outer shade-bands are formed, 
the proximal one absorbing the costal mark and the postmedian of the forewing. The extremely long stalking 
of the 2nd subcostal of the hindwing as characteristic as in the other sanctaria forms.
