Show 970 DR. A. G. BUTLER ON BUTTERFLIES [Nov. 28, common : an active and exceedingly restless insect of strong flight-very difficult to take if once missed." Of the second specimen, however, he writes'-" Newly emerged, evidently an easy prey in the wet and cold of early morning." This, then, is clearly the time to secure it. As might have been expected, the males are referable to the typical Northern species, not to the more southerly T. opalescens. To anyone with a correct eye for outline, the pattern of the primaries in these local forms is absolutely different, apart from all minor differences of colouring ; but the training of a lifetime is insufficient to enable some men to appreciate the most marked modifications of outline. 42. TERACOLUS INCRETUS Butl. Intermediate phase.- $ , Athi Valley, 4000 feet, 16th December ; S 2 - Athi escarpment, eastern side, Kitwi, 18th December ; $ , Msokani, 20th December, 1898 ; 6 , Tana River, 3800 feet, 16th January, 1899. Dry phase.- S, 2 $ J Tana River, 3800 feet, 16th January, 1899. Mr. Crawshay says of the male-" Very plentiful just here (A.thi Valley) : this and the following taken in numbers when playing together, with one stroke of the net." Of the female he says- " A n insect I have never before taken, and which, until settled, I imagined to be another, rather common just here-plain sulphur with an orange tip." In this conjecture Mr. Crawshay was quite correct. 43. TERACOLUS XANTHUS, var. METAGONE Holl. 6 , Tana River, 3800 feet, 16th January ; $ , Neugia, Kitwi, 30th January, 1899. o*. " Fairly common, frequents the more open country, dry and desert-like, and covered with thorny scrub " (R. G.). This is distinctly a dry-season phase, and differs from T. xanthus var. comptus in the entire absence of the internal grey streak on the primaries. 44.

The typical orange form of this species is bv no means too well represented in the Museum series. |
