The collection made by Emin Pasha contained half a dozen examples of T. anax, but not one of T. regina ; Mr. Crawshay's first collection, from Lake Mweru, contained one female T. anax aud his present collection contains one male, again T. anax; but perhaps this form is the only one in Central Africa, and typical T. regina is only produced, as a second form, as the species ranges southwards. 78.

" Purple-tipped black-veined White " (R. ft). This form seems so rare that it may well be mistaken for T. phlegyas ; in all probability it is the Nyasa form of that species. 79. TERACOLUS GAYISA. 3 .

Mr. Trimen (South African Butterflies, iii. p. 135) says:- " Having examined the types of subvenosus, Butl., from Victoria Nyanza, I find the female inseparable from that of T. gavisa, while the m de, though very near the corresponding sex of the species named, differs in wanting the inner black edging of the apical patch, and in the feeble development of the inner marginal blackish bar of the fore wings and the costal one of the hind wings." Although I do not admit that the type of T. subvenosus agrees absolutely with the typical female of T. gavisa, inasmuch as the oblique subapical bar on the front wings is much narrower in the latter, I am compelled by tbe receipt of many transitional specimens to agree with Mr. Trimen that m y female is only a slight variety of Wallengrens, and, moreover, that m y male is only a better-marked variety, though absolutely inseparable as a species. The series received from Dr. Gregory, taken in conjunction with the five examples in the present collection, renders the discrimination of the two forms T. gavisa and T. subvenosus simply hopeless. Unless T. hero is another variety of T. gavisa (which I think possible), I am of opinion that the female of T. sipylus would be better placed under T. hero than under T. gavisa, the black veining of the under surface being barely noticeable ; the whole of these forms might then sink under T. achine, T. hyperides being included as a starved form, though in some respects it more nearly resembles T. helle = a race of T. antevippe. |
