Show 776 ON LEPIDOPTERA FROM SOMALI-LAND. [NOV. 3, SATURNIID^E. 54. SATURNIA OUBIE. Bombyx oubie, Guerin, Voy. in Abyss, pi. 12. figs. 1, 2. Saturnia zaddachii, Dewitz, Mitth. d. Munch. Ver. 1879, Taf. fig. 6. Four females, all more or less damaged.-Thrupp. From the figures of this species I had always supposed it to be allied to Antheraa tyrrea (which, however, is hardly a typical Antheraa). In coloration it corresponds with A. belina, and in pattern, excepting for its pale nervures, with A. hersilia. After careful examination of all its structural characters, however, it appears not to differ from typical Saturnia ; the antennae, with their alternate unequal serration, the short palpi, short proboscis, legs, and nervures, including the apical furcation of the subcostal branches, all correspond with those of the female S. pavonia-major, and yet the pattern is distinctly that of the African representatives of Antheraa. I can find no reason for separating S. zaddachii from S. oubie ; as Herr Dewitz does not mention the figure by M . Guerin, it was most probably overlooked by him ; at the same time I should greatly prefer to use the later and less barbarous name if it were possible. One of the specimens obtained by Mr. Thrupp shows a curious modification of wing-structure, the upper radial of the left-hand primary being united by a cross-vein to the last subcostal branch.
