as it has the same extremely long stalking of the subcostal of the hindwing and the same tone; it is almost 
devoid of markings, excepting the cell-dot, and the face is very pale (in 1 B reddish brown, in the other 3 more 
as in mauritanica). 
B. ochrolutearia Trti. was described provisionally as a Tephrina and the type was kindly lent 
to Dr. Wehrli in connection with his section of the present volume. It proves to be a Brachyglossina and 
indeed, almost certainly, a strongly marked member of the mauritanica group. Tongue reduced to diminutive 
convergent filaments. Antenna with the ends of the joints produced, fascicles about 1%- Hindtarsus about 
Y 3 tibia. Head and body concolorous with the wings, which have the sandy ochreous colour which is so character¬ 
istic of the desert forms. Lines very slender, the postmedian rather better expressed than the antemedian, 
brownish; proximal subterminal shade developed; blackish terminal line very slender, scarcely noticeable, 
interrupted by the veins, accompanied proximally by a slender light line. Underside uniformly lutescent, with 
only the subterminal shade (marked by interneural spots) and minute cell-dots. The very straight costal margin 
of the forewing recalls the type of mauritanica , but the wing is somewhat less broad and the terrnen of the hind¬ 
wing not cpiite so strongly rounded. 1 B from Bus Hamra, Cyrenaica, in early April. 
Bo acidalaria F. Wagn. It has been variously proposed to unite this with mauritanica or with tan- 
talidis or to leave it separate, and until the genitalia have been examined its exact position must remain uncertain. 
The dense “d ark" irroration even raises a doubt whether it belongs to the mauritanica group at all. Dr. Zerny, 
who has re-examined Wagner's type, writes that it differs much in markings, coloration and wing-form from 
culoti and that the ends of the antennal joints seem to project less and to bear somewhat shorter ciliation. 
Considering how local several of these Brachyglossina are, it appears on the whole probable that the present 
species still awaits rediscovery. There is however, a Sebdou Brachyglossina which, it has been suggested, might 
possibly represent acidularia notwithstanding the wide geographical separation; and as the 3 specimens (2 BS, 
1 $) before me are very worn, whereas I understand from Dr. Wehrli that he has a series of a rather large 
species from that locality (presumably the same species as ours), I have allowed this determination for the 
present. Tegumen broader than in mauritanica , its shoulders rather prominent, uncus very evenly 
curved, so that its end is at a right angle with its base. Valves also very distinctive, the proximal half 
much broader than distal half, at about (or scarcely) % with a fine pointed process. The large cornuti are 
wanting, though there are 1 or 2 small ones on the vesica. Bethhne-Baker cpiite plausibly determined the $ 
as a second mauritanica, but, as will be seen from the above, the uncus, valve and cornuti deviate widely. I 
have recently examined a B (also badly worn) from Les Pins, ca. 7 km S. of Magenta (Rotrou) which agrees 
absolutely with the Sebdou in the genitalia, though the remnant of the postmedian looks punctiform, somewhat 
as in S. oranaria (see p. 69). 
B. macracantha sp. n. (13 k). B- Face and palpus very dark. Tongue minute. Hindtibia rather elongate; 
tarsus extremely short (about 1 / 5 ). Collar somewhat more ochreous-tinged than vertex and thorax. Wings 
more whitish than in the rest of the group, the irroration moderately copious, but not very dark. Forewing 
with the distal curve of the costa rather slighter than in most of the group; cell long (almost %); median line 
extremely faint, ante- and postmedian widely separated; subterminal shading somewhat as in mzabensis or 
perhaps rather more tripartite (somewhat as in trigeminata and some other Sterrha, but relatively weak); fringe 
with the proximal dots small and faint. Hindwing slightly elongate, termen rounded; median shade less obsol¬ 
escent than on forewing. Underside more glossy, with costal borders more buff-tinged; cell-dots slight; post¬ 
median line fairly distinct. Valve less elongate than in mauritanica and with a long conspicuous thorn from 
“costa” near its tip, as in no other Brachyglossina. Djebel Gueddelane, near Lambese, ca. 1600 -2000 m, July 
1913 (H. Powell); type from the Oberthur collection. A Lambese $ from the same source, September 1913, 
which may well belong to it, is slightly broader-winged and more stramineous, its cell-dots a little stronger, lines 
rather weaker. 
B. maroccana Wehrli (7 b). Dr. Wehrli informs me that he lias not yet obtained any further light 
upon this Brachyglossina. If it is really, as originally regarded, a geographical form of the following, it will 
of course provide the oldest name for the collective species. But as I, like its anther, have never seen any other 
of the genus with the median area different in ground-colour from the proximal and distal, it is certainly more 
expedient for the present to treat it as a separate species, which awaits rediscovery, than to complicate the 
synonymy with a probably inaccurate union. Zerny "s suggestion that it may be a form of oranaria seems to 
me still less acceptable. 
B. paroranaria Wehrli, sp. n. (= oranaria Wehrli olim, nec B.-Haas) (6 b). “This species, generally 
regarded as St. oranaria, has been shown by the examination which I made of the B genitalia to be totally 
different from the B type of oranaria, which is before me today for a comparative description. But the anat¬ 
omical conditions show further that the new species has nothing at all to do with B. pseudoranaria Zerny from
