dish ochreous, are here whitish ochreoiis, dark-dotted; postniedian line mueli straighter and not lunulate. on 
the veins marked with fuscous dashes. Cape Comny. 
B. praecanaria H.-Sch. (18 a). Recognizable not only by the still more oldique, more sinuous and prarranaria. 
lunulate postmedian but especially by the whitish band which bounds it distally. Very variable in the relative 
strength of the different lines, the distance which separates them and even the degree of the slant of the post¬ 
median. Capo Colony. — ab. subinterrupta nov. has the postmedian so proximally placed and so weak that the Hublnlcrrui)- 
white band beyond it interrupts the central area at its narrowest part (region of tlie fold); from the 2 nd sub- 
median to the hindmargin the median area reappears as a blackish spot of about 1 mm diameter. Willowmore 
(G. V. Son), among a very variable series. — rufivena Warr. (18 b). Rather small (? narrower-winged) and rufireHci. 
brownish, the veins rather bright, postmedian rather more strongly dentate, its white bordering broad. Orange 
Free State (type), Murraysburg, etc.; possibly a subspecies but, in view of the great variability of the species, 
probably a mere aberration. 
B. fontis S'p. n. (log). Very similar in colour and markings to deterior, yet structurally so different that fonlis. 
it might almost be accorded a separate genus. Palpus soirewhat less short. Pectinations rather less extremely 
long. Foretibia without the spine. Abdomen somewhat more robust. Wings less extremely elongate, tone 
somewhat browmer, markings of forewing appreciably less obliqiie; fringes distinctly cheqiiered. Cape Colony: 
Deelfontein, 2 d'd' the British Museum. Perhaps a link with Orcjjjiodes. 
B. uloprora sp. n. (16 e) may be regarded as another interesting link with Orgyiodes, towards which idoprora. 
it makes some further apj^roach in the predominantly ochreous colouring. Palpus extending considerably 
beyond frons and clothed beneath with long projecting hair. Foretibia without spine. Wing-shape, venation 
and pattern quite typical; forewing more speckled and with broader white stripes bounding the median area; 
hindwing feebly marked, excepting the cell-spot; fringes sharply chequered. “Natal'’, a fine ^ in the British 
Museum, from the Adams collection. 
23. Genus; Orgyiodes BMrr. 
Differs from Biclavigera in the smaller eye, longhaired palpus and absence of foretibial claw, as well 
as in the shape and pattern. Antenna of S' not pectinate quite to apex. Wings (especially the hindwing) less 
elongate, cell of hindwing only about costal vein approximated to it for a shorter distance. Only one 
species known. 
0. caparia Walk. (= capicolaria Feld.) (16 h). A small species, of a reddish brown colour, with the capnria. 
hindwing and underside very feebly marked. Apparently confined to CApe Colony. 
24. Genus: Istiirgia Him. 
(See vol. 4, p. 317.) 
To this Holarctic genus is referred provisionally one Soiith African species. It was described as a Fur- 
ranthis (synonym of Fidonia), but agrees more nearly with Isturgia as at present characterized, though prob¬ 
ably requiring a separate genus. Face somewhat protuberant. Tongue present. Palpus better developed than 
in the two preceding, long-scaled beneath, but without the hairiness of true Isturgia. Antennal pectinations 
moderately long. Hindtibia with all spurs. Neither cell elongate. Forewing in the with a fovea; the coincident 
subcostal anastomosing successively with costal and 4th—5th subcostal. 
I. focularia Hb.-Oey. (16 h). Evidently a day-flier, recognizable at once by its orange, sharply marked joeutaria. 
hindwing and underside. It belongs chiefly to Cape Colony but is recorded also from Bloemfontein. There is 
apparently a succession of broods. 
25. Genus: Aetlieometrsi Front. 
Affinities quite uncertain, though I have suspected there may be some possible connection with the 
Palaearctic Atomorpdia (Vol. 4, p. 396). Face iwotuberant. Tongue vestigial. Palpiis very short and slender. 
Antenna of A pectinate to about - 3 , with rather long, rather lax branches. Foretibia without claw; hindtibia 
with all spurs. Abdomen moderately robust. Forewing with a slight fovea; cell well over W; 1 st subcostal 
anastomosing with costal, 2nd from cell. Hindwing with costal anastomosing rvith cell to about I/ 3 , 2nd sub¬ 
costal shortly stalked. Type: iconoclasis Prout. 
A. iconoclasis Prout (15 i). Recognizable by the curiously shaped lines of the forewing, which, with iconocta.'il'). 
the aid of the cell-spot, may be likened to a crudely shaped and damaged bust in profile. Both wings beneath
