118 TERACOLUS. 



gentleman, and purchased l)y the Museum from Mr. Janson, with the somewhat 

 comprehensive localities of " Orange Eiver, Diamond Fields and Transvaal," an area, 

 as we have learnt through the bitter experience of our war with the Boers, of 

 somewhat wide extent. The locality "Orange River" of 1889, when Dr. Trimen 

 wrote, is now " South Africa," and we may tiierefore dismiss the original locality as 

 unproven. A specimen from Kimberley is in the Godnuiu-Salvin collection, and Dr. 

 Trimen mentions the occurrence of the species in Damara Land. Thence it appears 

 to extend to the eastward into Griqua Land, north to the Eastern Transvaal and 

 Mashona Land. Specimens are in the British Museum from N.E. Natal, collected 

 by that splendid old example of a British naturalist, the late E. C Buxton, and these 

 were no doubt obtained on his expedition to Santa Lucia Bay. 



Mr. Guy Marshall writes of 1'. lais .- " This is a distinct little species of the 

 T. acMiie group from S.W. Africa, and may be distinguished from its allies by the 

 small, very oblique, orange apical patch, whieli has a distinct border of black along 

 its inner edge. I have only seen dry-season specimens." Of T. luili/attes he says : 

 "This little species is at present known only from N.E. Natal and the Transvaal, but 

 it seems to be very scarce, and only dry-season specimens have been captured. It 

 combines several characters of the dry forms of T. achine (Cram.) and T. evijrpe and 

 T. onijiliale, but is nearer the former. The females in the British Museum, which 

 appear to have been selected by guess-work, are quite similar to those of T. achine 

 (dry)." 



Dr. Butler's notes on this species are as follows : " The female of T. lais, the wet- 

 (not dry-) season form, bears a vague resemblance to that of tlie T. efiida, var. 

 T. bimbura, but the orange sub-apical bar has no inner blackish edging and there is no 

 spot on the second median areole of the primaries ; the two marginal spots nearest to 

 the apex of the secondaries are also confluent ; on the under surface the basal area and 

 the apical border of the primaries and the secondaries, witli tlie exception of a discal 

 patch towards the apex, are washed with pale buff; the orange sub-apical curved bar 

 of the primaries is paler than above, but the interno-median black spot is distinct. 

 The males vary greatly in expanse, the type measuring about 34 mm., and a second 

 example from the Godman and Salvin collection no less tlian 4G. It approaches 

 T. cpJii/ia, but has more nearly the upper-surface pattern of T. biinbnra, with pure 

 white under surface (indistinctly irrorated with black scales when examined through a 

 lens), the disco-cellular dots black, that of the secondaries attached to an orange spot ; 

 the costa of these wings is also narrowly orange towards the base. 



"My incorrect identification of the sexes of the drj^-season form [T. halijattcs) led 

 Mr. Marshall into error. The male of the latter is much like the wet-season form 

 above, but both sexes Ijclow are alike, witli grey specked ros}' apical area to the
