more intensive straw-yellow than those from Ijjoukak. 
p. 65, to S. nitidata H.-Sch. A single $ from N. E. Szechuan (Ma-tou-shan, 600 1000 m) is too much nitidata. 
worn to be determined with certainty, but Djakonov does not think it can belong to any other species; probably 
when he examined it his attention had not been called to the venational peculiarity. 
p. 66, to S. deversaria (Vol. 4, pi. 4g). — ab. ferenigra Homberg. Fore- and hindwing entirely suffused ferenigra. 
with uniform dark brownish grey (soot-colour), obliterating all the markings except the subterminal, which 
stands out in light grey-yellowish on both wings. A $ from Herault (St. Guilhem-le-Desert). 
p. 66, to S. aversata L. (Vol. 4, pi. 4 g). Mr. C. N. Hawkins has recently shown, as the result of some aversaia. 
experiments in breeding from a $ of the name-typical (banded) form, that this form is heterozygous and the 
ab. remutata homozygous. He did not, however, obtain any pairing of the banded forms. 
p. 67, to Sterrha: 
S. (?) punctabilineatella D. Luc. “24 mm.”, which, if this denotes a wing-length of 13 or 14 mm, will pundabili- 
be one of the larger Sterrha, or perhaps Scopula. Whitish grey. Forewing with antemedian weak, median shade neaidla. 
outside the elongate cell-dot, postmedian punctiform, termen ( ? base of fringe) with black dots, subterminals 
brown, indistinct, parallel with the postmedian. Hindwing with median shade sharply expressed, close to the 
cell-clot; outer markings corresponding to those of forewing. Underside similarly but less sharply marked. 
Antenna long, “slightly pectinate” (? fasciculate). Founded on 2 So from Agadir, 11 April 1936. Unknown 
to me. 
p. 67, to Brachyglossina. With the kind assistance of Mr. A. H. Stringer, supplemented by valuable 
notes from Dr. Sterneck and Dr. Wehrli, I have made a study of nearly all the accessible material in this 
genus, especially of the hitherto very perplexing group which has been wrongly confused with ( Sterrha ?) oran- 
aria B.-Haas. The examination of the genitalia shows that we have to do with several cpiite distinct but super¬ 
ficially very similar species, exclusively North African. Fortunately some of the most useful distinctions are 
in the valve, the anellus (when developed) and the distal parts of the penis and are easily seen by the removal, 
or even the temporary displacement of the dense fringe of hair-scales which arises from the 8th sternite. On 
the other hand the exact length of the hindtarsus, so valuable in affording specific characters in Scopula and 
most Sterrha , is here evidently somewhat inconstant and therefore in some cases illusory. The tongue, too, 
though always very short, varies in length; see especially paroranaria. Uncus simple, its tip slightly hooked; 
Dr. Sterneck notes that in some species it is enclosed in a hyaline skin which gives it a stouter appearance. 
Valve nearly always long and slender, tapering to a sharp, more or less bent or twisted point. Aedoeagus nearly 
always with 1 large cornutus, usually also (more distally) a few small ones; but see the mauritanica group. 
The essential wing-pattern is always similar, except in a very few almost unicolorous forms, but the median 
and subterminal shades may be strong, weak or wanting; Sterneck remarks on the occasional presence of 
the antemedian line on the underside, a development which he has not observed in any Sterrha. 
B. tantalidis Trti. This and the two following are nearly related, sharing the sandy colouring, the weak tantalidis. 
expression of the lines, the simple, unarmed valves, the absence of anellus and the strong development of the 
cornuti. These number 6, of about ecpial length and placed nearly side-by-side, though the last 2 or 3 arise 
somewhat more distally. Valve shorter than in mauritanica, rather more curved, more hairy, other parts of 
the genitalia also reduced. Otherwise the structure is remarkably similar. Only known from Cyrenaica. 
B. mauritanica B.-Bah. still remains unmatched. The face is perhaps a little more black-mixed than mauritanica. 
in any known tantalidis: and the very fully rounded termen of the hindwing helps to give it a distinctive 
appearance. In the genitalia, the most striking difference is in the cornuti, which are considerably more numerous 
(about 12) and much more irregularly disposed. On the valve see tantalidis. 
B. mzabensis sp. n. (18 b). In structure still closer to mauritanica, of which it might almost be regarded mzabensis. 
as a narrow-winged southern race. The valve is appreciably longer, tapering more gradually, and has the slight 
costal projection at the proximal end of the tapered part even slighter; the cornuti are similarly arranged. The 
hindtarsus, in all the 4 known examples, is a little less shortened than in tantalidis and. probably, than in mauri¬ 
tanica. Superficially, all are distinguishable by their more definite grey subterminal maculation and conse¬ 
quently more pronounced pale subterminal “line”, but it is doubtful whether a long series will support this 
distinction. Hindwing, in all but one, with the stalking of the 2nd subcostal extremely long. Oued N 9 a. M'zab

1912 (V. Faroult), 2 all unfortunately somewhat worn. I have long had an undetermined specimen from 
El Kantara, 14 April 1913 (F. A. Buxton) which may well be a larger and less narrow-winged to mzabensis,
