Soc. 1893, p. 133 pl. viii. fig. 9. o*, Tugela Biver, near Weneen, 2500 feet, 5th and 13th November, 1896. 58. LYCAENESTHES OTACILIA, Trimen. 2 , Estcourt, 13th October, 1896. " Abundant later on, on Acacias." It is new to the Museum. 59. LYCAENESTHES AMARAH, Guer. Tugela Biver, 15th and 19th November, 1896. 60. SCOLITANTIDES METOPHIS, Wallgr. Tugela Biver, 3rd, 5th, 6th, 8th, and 15th November, 1896. I do not for a moment believe that it is possible to distinguish /$. barherce from 8. metophls; in a series of six examples, obtained by Mr. Marshall on the same day, the expanse of wings varies from 16 to 20 millimetres, and the submarginal white spots on the secondaries from one to three on opposite wings of the same example : the character upon which the former may yet be separated, so far as our present series goes, is the absence of the conspicuous (but somewhat variable) white submarginal spot preceding the second cluster of silver scales on the under surface of the secondaries; and that appears to m e to be insufficient. It is hard upon me, considering the reputation with which I have been saddled of being a multiplier of names, to have to call in question the validity of one of m y friend Trimen's species; but I must confess that, in bolstering up L. barherce, he departs so widely from the " broad views " which used to characterize his early work that I a m fain to remonstrate. 61. CACYREUS LINGEUS, Cramer. Karkloof, 12th and 14th February, 1897. The generic name of Hyreus being preoccupied in Birds, I will rename this genus Cacyreus, taking C. lingeus as type. 62. CACYREUS PALEMON, Cramer. (Blate L. fig. 4.) Niginya, 5800 feet, Ulundi, 14th September, 1896. Mr. Marshall writes-" Y o u will observe that the specimens from Ulundi are of the usual bluish-coppery tinge, but round here neither sex ever shows a trace of blue ; there is also a slight but seemingly constant difference on the underside: perhaps it should be regarded as a subspecies." I think myself that it is a distinct species. 63. C A C Y R E U S M A R S H A L L I , sp. n. (Plate L. fig. 5.) Differs from C. palcemon in its squarer form, the costa of the primaries being shorter and the secondaries with shorter abdominal margin. Owing to the bronze-brown colouring of the |
