STERRHA. By L. B. Prout. 
siowpUla. Z. stenoptila Prout is j^erha^DS a very drill-coloured form of the preceding, almost without reddish 
tinge, the cell-dots sharply black, the lines not entirely obsolete, thus somewhat intermediate towards relicfata. 
Transvaal. I have seen a dingy aberration of roseocincta from Senegal which in a measure links the two 
species together. 
25. Genus; Sterrha Him. 
This genus, to which I formerly (sec Vol. 4, p. 141) assigned the younger name of PiycliO'poda, is at 
least as rich in sjiecies as Scojmla, with which the early entomologists united it, though there is really 
very little connection. Much less homogeneous than Scopula, especially in the (J structures, but I have not 
yet found a satisfactory method of sid)dividing it. Palpus short. Tongue present, hut sometimes weak. 
Antenna of cj ciliate or fasciculate. Hindtibia of cJ generally al)orted and sjourless, of $ with terminal spurs 
only. Forewing with simide areole, or occasionally (as in some Ayititrygodes) without anastomosis of the 
1st subcostal. Hindwing with 2nd subcostal stalked, often very long-stalked; costal very occasionally {UUi- 
etc.) anastomosing strongly with cell, as in the Larentiinae. On the early stages, so far as known, 
see Vol. 4, p. 141. Africa, excepting Palaearctic N. Africa, is relatively poor in species, but probably very 
many still remain to be discovered; the name-typical section, with terminal spurs present on the ^ hind- 
tibia, is at present unrepresented here. 
aurifUia. S. auriflua IFarr. (7 i) is a pretty little species, with sinuous rosy bands on an ochre-yellow ground¬ 
colour. Head entirely rosy. with antennal joints projecting, ciliation fairly long, hindleg weak, with 
tarsus very short. Barotse; also known from S. Rhodesia. A much larger (J from Angola, with rather more 
ocno-onata. slender bands, perhaps represents a separate race. — oenozoiiata Warr., only known to me in the $, is pro¬ 
bably a tiny form of auriflua, rather duller-coloured and with tlie bands perhaps a little less sinuous. Dar- 
es-Salaam and Kilwa, E. Africa. 
latiduvia. S. laticlavia Prout. Near atiriflita (7 i) in structure, but larger (18 mm), longer-winged, the ground¬ 
colour somewhat paler, the markings more tinged with pur])le, more oblique, the postmedian of the forewing 
more slender, farther from the median, the markings of the hindwing very slender, excepting the subterminal 
band. Abdomen and costal edge of forewing with some blackish admixture. Southern Rhodesia. 
angusta. S. angusta Btlr. (8 h). Hindleg of rather short and slender, but with the tarsus relatively well deve¬ 
loped. Distinguishable from the neighbouring species by the didler purple markings, the subterminal band 
almost reaching distal margin, a cell-dot present on forewing. Nyasa (type) and N. E. Congo ( ? race). 
pcricatlcs. S. pericalles Prout (8 k). Still more elongate-winged than laticlavia, more suggestive of a Zygophyxia-, 
subterminal pink band less broad than in the two following, antemedian band of forewing lost in an extensive 
costal suffusion. Transvaal (ty])e), S. Rhodesia and Orange Free State. 
cxquisiia. S. exQUisita ITfljT. (7 i). Patagia and tegulae rosy, some rosy maculation on abdomen above. Ground¬ 
colour scarcely yellower than olive-buff; the rosy submarginal band and on the forewing the very obliquely 
bounded basal-costal patch are the only markings, both above and beneath. Described from Zomba (Nyasa- 
land) but known also from Angola. 
iuqiiisita. S. inquisita Prout (8h). Possildy a race of the preceding, yellower, the band more purple, more 
proximally ])laced, the basal patch shorter anteriorly. Face and palpus purple; vertex buff-yellow. Body 
buff-yellow, the abdomen above much clouded with didl pinqde. Legs predominantly yellow, anterior coxa 
and femur marked with purple. Forewing scarcely so extremely narrow as in exquisita and angusta-, beneath 
similar, the proximal patch rather weaker. French Guinea: Beyla, 1900 feet, type $. I have an identical, 
but damaged, $ from Fort Grampel, French Congo. 
hasicosialis. S. basicostalis Warr. (7 i) is a small species, somewhat recalling some forms of subsaturata Guen. (Vol. 4, 
p. 100) but with a dark streak along the costal margin of the forewing proximally and with the hindwing 
rather more rounded. G with antennal ciliation not long, hindtibia weak, somewhat hairy, tarsus about as 
pariicolor. long as tibia'. — ab. particolor Prout has the median area darkened with dense reddish-grey irroration. 
The species is distributed from the Transvaal to Pondoland. 
plcsioscotia. S. plesioscotia P)’o?d (8 k) is still smaller, narrow-winged; hindtibia of G slender, tarsus slightly longer 
than tibia. Base of costa of forewing blackish, rather than (as in basicostalis) brown; forewing beneath with 
extensive dark suffusion. The large cell-dots and absence of clouding between postmedian and subterminal 
lines distinguish it from scyuamulata and the antennal ciliation seems to be shorter. Costal edge more arched 
than in yiiacrostyla. Founded on a from Dunbrody, Cape Colony. 
macrostyla. S. macrostyla Warr. (7 i) is the smallest of the group and the only one yet known from East Africa. 
Antennal joints of the J slightly projecting, with the ciliation moderate. Hindleg slender, perhaps relatively
