This striking species is very nearly allied to the southern T. annce (Wallgr.), and had I seen only a single specimen I should have regarded it as a sport of that species. But, thanks to Miss E. M . Sharpe, I have been able to examine a fair series of both sexes, and I think there is little doubt that it is entitled to specific rank. In the male the only differences from T. annce are (a) its distinctly larger size, (b) the curious ochreous-yellow colouring of the apical patch, and (c) the inner black edging of apical patch, which is narrow on costa and broadens to hind margin, whereas in T. annce it is practically the same width throughout. The only constant distinction that I can find in the female is the complete absence of any grey clouding along inner margin of fore wings. At present T. hildebrandti has only been received from the basin of the Sabaki River, in East Africa, between 2° and 4° S. lat. At Hartley Hills, W . Mashunaland, I caught what at the time 1 took to be a sport of the dry-season form of T. annce (=wallengrenll, Butl.), in which the apical patch was golden yellow ; I am unable to refer to the specimen at present, but it may prove to be hildebrandti. 46. TERACOLUS GUENEI. Anthocharis guenei, Mabille, Bull. Soc. Ent. Fr. p. 38(1877), and Grand. Hist, Madag., Lep. i. p. 298, pl. xl. figs. 7-9 (1887). The small size of the apical patch and its strong sinuation on the inner edge give this species almost the appearance of a dwarfed specimen of T. theogone, Boisd., on the upperside, but the discal spots below show its relationship to the T. eupompe group. The small variety mentioned by M . Mabille is clearly the dry-season form. It is peculiar to Madagascar. 47. TERACOLUS SIGA. Anthocharis siga, Mabille, Le Naturaliste, p. 100 (1882), and Grand. Hist. Madag., Lep. i. pl. xii. fig. 4 (1887). This species was founded by M . Mabille on a single male from Madagascar. From the figure it looks suspiciously like a dwarfed specimen of T. guenei, in which the underside markings have failed as happens in T. eupompe; but until further examples are forthcoming it is perhaps advisable to keep it separate. 48. TERACOLUS EULIMENE. Pontia eulimene, Klug, Symb. Phys., Ins. pl. vii fi>s 5-8 (1829). 6 A most distinct species with no very near allies. Mr Butler refers it to the genus Ixlas, but it seems preferable to retain it as a Teracolus. Recorded from Dongola and the White Nile. |
