BETHUNE-BAKER ON [June 20, Female specimens from Mysol and one in Dr. Staudinger's collection from Waigiou agree best with Dr. Felder's figure, but a female in Messrs. Godman and Salvin's possession has a rather less extensive blue band on hind wing beneath. These gentlemen also possess a female from Aru Islands, which does not differ from the N e w Guinea female except in its smaller size (If inch). This is a somewhat puzzling species on account of the exceptional difference in the widths of the blue bands on underside of hind wdngs of the two sexes and also the varying width of this band in the female, no two specimens, even from the same locality, being identical. Judging from the arrangement in the British Museum, Mr. Butler appears to think that Boisduval's name (sebce) should be used for the Aru Islands form, but I am unable to distinguish it from T. apollonius and think it is quite evident from the context of Boisduval's description that he was simply redescribing Cramer's insect. Probably the specimen Godart described from Bawak (Encycl. Meth. p. 578) was a representative of T. apollonius. Genitalia very closely allied to those of T. danis, but hooks shorter. Penis with hinged cover longer than lower portion. (Plate XLVII. figs. 2, 2 a.) The drawing is from a N e w Guinea example. Var. SUPOUS, nov. (Plate XLV. fig. 7.) " Lyccena danis, Cr., var. supous, Bibbe," Staud. M S . Hah. W a m m o Dobbo, Aru Is. (C. Bible) (Mus. Staud.). Dr. Staudinger has sent us a female with the above M S . name, which, in the absence of more material and without seeing the male, we prefer to treat as a variety. On the upperside it is quite typical, but beneath it differs from Dr. Felder's figure in the hind wing having a somewhat wider white band and considerably less blue. THYSONOTIS REGINA. Thysonotis regina, Kirby, Ann. Mag. Nat. Hist. (6) xvi. p. 163 (1889). Hah. Normanby I., Louisiade Archipelago. This species may be distinguished from the preceding principal y by having the disks of the fore wing in the male almost completely covered with blue. The onlv specimens we have seen are the types in the British Museum, which do not vary. They were collected by Mr. Basil Thomson in 1888, and are the most easterly examples of this group at present known. M r Kirby (loc. cit. p. 164) writes of this insect: " Size of T. sebce. West., but the male more resembles T danis, Cr. :"but Westwood in his description clearly only dealt with Cramer's species, so that the meaning of this remark is not quite apparent. |
