Estcourt, 6th, 23rd, and 29th September, 1st, 2nd, 3rd, and 12th October ; Niginya, Ulundi, 10th, 12th, 13th, 14th, 16th, and 17th September ; Frere, 2nd and 10th December, 1896. " This appears to be a very variable species, ranging from orange with brown markings to brown with very slight orange markings. I am inclined to consider the orange form as the spring one, and the brown as the late summer and autumn form, as the species does not occur in mid-winter. However, I have hardly worked out the matter sufficiently to speak definitely yet, but I have got several young larvae from eggs laid by an orange female. She deposited them at the roots of gra^s, burying them just below the surface, a method of ovipositing which I have never seen in any other species." Perhaps it may assist Mr. Marshall to indicate the times of capture of the two forms as represented by the twenty-eight examples which he has sent us in the present series and which (being in papers) were not easily examined until set:- Orange form. Intermediate. Brown. 10th Sept.-lOth Dec. 2nd-12th Oct. 29th Sept.-2nd Dec. 18 examples. 4 examples. 6 examples. The extremes and intermediates were captured on the same days and all in perfect condition ; therefore I think Mr. Marshall will find that they have no seasonal value. 70. ALCEIDES THYRA, Linn. Niginya, Ulundi, 6000 feet, 10th and 15th September, 1896. 71. ZERITIS AMANGA, Westw. Tugela near Weenen, 2500 feet, 5th November, 1896. 72. ZERITIS HARPAX, Fabr. Estcourt, 23rd and 29th September; 3rd, 4th, 5th, 8th, 12th, 14th, 15th, 16th, and 17th October, 1896. CHRYSORITIS, gen. nov. Intermediate in character between Chrysorychla and Clgaritls, having almost the form of the latter, but much more nearly resembling the former in the character of the under-surface markings. It differs from all the forms of the Zeritis group and from Chrysophanus in having no apical furca to the subcostal vein of the primaries, this vein therefore being quadriramose; the upper radial also is emitted from the subcostal vein at some distance beyond the end of the cell. Type, Zeritis oreas, Trimen. |
