142 COLons 0'-f. omphaloides (Btl.) (Plates XIX-XX, fig. 24). :Ftrucoills omp/wlvidcs Btl., 1876, l.c.: lSI (South Africa). This is a somewhat intermediate form of the male, possessing a forewing dark supra­ marginal stripe, but the postdiscal dark band of the hind wing is missing or vestigial. The form is very common in the late autumn, and flies together with the first batches of the f. Ilieogol1e Bsdv. The females taken with omphaloides males are of the typical dry­ :;ca~on form theogone Bsdv., and for this reason the name is applied only to the males. f. mediata (Talbot) Colotis (pri, p. mediala Talbot, 1939, Trails. ell'. Soc. Lond. 88: 199. A regional summer form distributed in South-East Angola, South and South-East Congo, )Jyasaland, )Jorthern Rhodesia and the extreme northern portion of Southern H.hodesia. The males diJ'icr from the f. omphale Godt. in the slight reduction of the subapical orange area of forewing, besides in the fusion of the marginal spots of the hindwing. The female is very similar to that of f. omphale from which it differs in the reduction of the orange area of forewing. Recorded by Talbot from Mashonaland (Salisbury) . Q-f. ochreata (Talbot). c. evippc omphale ~- f. ochrea'a Talbot, 1939, I.c.: 199 (Ta.nga.nyika). This is the yellow form of female which is common in parts of East Africa but has not been recorded from Southern Africa. However, as certain specimens from South Africa (~atal) have a distinct yellowish tinge, it is probable that the form will be found in the northern part of our eastern coastal area. ) 1 9-f. ochroleucus (Talbot) 1 0 C.

The form occurs with the f. mediata Talb., but the records given r e bv Talbot state" Rhodesia" withollt mention of " ?'>/orthern " or " Southern ". As h s i l t."mediata Talb. is recorded from Salisbury, the occurrence of f. ochroleuws Talb. within b u our faunistic limits may be presumed. P e h t f. theogone (Bsdv.)

The paratype is very similar to the holotype, but smaller, with less pronounced yellow suffusion of upperside, and with smaller, almost obsolete marginal spots of hind­ wing; the postdiscal band is absent altogether. Expanse: hololype : 42 mm; paratype: 37 mm. NOTE: A scale impression of a Victoria Falls male, made by Mr. G. C. Clark, repre­ sents an extreme dr.'>' form resembling C. an/e"'ippe f. harmonides, but lacking the disco­ cellular spot of forewing, and with the orange area not as reddish as in antco'ippe. Thi::: form, which cannot be properly described without the actual specimen, is the male equivalent of the <i>-f. arClIata, and should be designated under the same name. f. namaqua, f. nov. (Plates XIX-XX, fig . 28). lI% /ypc : 0, l{uboos, Richtcrsveld, 19 :\o\"ember, 1933 (G. van Son). Description: Forewing with outer margin less convex than in other Southern African forms. Upperside: as in f. theogone Bsdv., but there is no trace of marginal dots in the hindwing. Underside: forewing, ground-colour white, apical area pale ochraceous yellow, with an orange band at its inner edge from costa to vein ;\J:1 ; a minute discocellular dot; hindwing : creamy, very slightly flushed with pinkish, costal area suffused with ochraceous-yellow; a small black discocellular dot, edged with orange on inner side; a faint brownish postdiscal band; some scattered brownish scales in the ) 1 costal, basal and postdiscal area, but no distinct striolation as in f. theogone. Expanse: 1 0 36 mm. 2 d Remarks: The present form is of special interest, as it combines extreme dry-season e t characters of the upperside (reduction of black markings, which are even more reduced a d than in extreme dry specimens of f. /heogone Bsdv.) with an underside approaching the ( r summer forms, particularly in the presence of a minute discocellular spot on the forewing, e h s a character only occasionally found in f. omphale Godt., but ne,'er in f. theogolle Bsdv. i l b This fact is very significant, as it demonstrates the independence of the variation in the u P development of black markings from that of the underside colouration, and militates e h against the recognition of the subspecific ,'alue of differences in forms of different regions t y in the same season. b Expanse: 28--48 mm.
