Z. vol. xl. p. 358 (1879); id. ibid. vol. xlv. p. 156 (1884); id. I.e. A. argyrospila, Ploetz, MS. Ceratrichia argyrosticta, Wats. P. Z. S. 1893, p. 117. Hab. Cameroons, Valley of the Ogove, Aburi (Ploetz). This is a very common species. I have an enormous series, taken at different times and places. There is not a shadow of doubt in my mind that the above synonymy is correct. The females are very variable upon the upperside of the wings, but agree very well with the males on the underside, though in both the male and the female sex the silvery centres of the spots on the underside are often suffused with dark brown, and the silvery colour is rendered obsolete. COBALUS, Hiibn. 274. C. (?) CORVINUS, Mab. Cobcdus corvinus, Mab. Bull. Soc. Ent. France, (6) vol. ix. p. clxix (1889). Hab. Sierra Leone (Mabille). I allow this species to remain in this genus, to which it has been assigned by its author, though it is quite plain to me that it does not really belong here. I have the type before me as I write, but as it is unique and in poor condition, so that I cannot without great risk of further injury make a close anatomical investigation, I must leave its location undecided. It seems superficially to show a general relationship to pulvina, Ploetz, and nox, Mab., but the wings are more fragile and relatively longer, and the insect is not so robust. 275. C. (?) ATRIO, Mab. Cobcdus atrio, Mab. C. R. Soc. Ent. Belg. 1891, p. lxxxii. A figure of the type kindly lent me by Mons. MabiUe suggests that this is the female of Semalea pulvina, Ploetz (q. v.). It is certainly not a Cobalus, as that genus is South-American. ANDRONYMUS, gen. nov. Antenna? more than half the length of the primaries, slender; club moderate, fusiform, slightly recurved at the tip. Palpi divergent, with the first and second joints heavily clothed with scales, the third joint naked, aciculate, erect, as high as the vertex of the head. Fore wing elongated, with the inner margin considerably longer than the outer margin, blunt at the apex, and slightly excavated between the extremities of veins 1 and 3. Cell narrow, elongated, nearly two-thirds the length of the costa : vein 12 reaching the costa before the end of the cell; upper discocellular short, but distinct, at right angles to the upper margin of cell; middle discocellular relatively long, curved inwardly; lower disco-. |
