XYMPHALIN.E. 291 



The ^ P. Tarquinm is apparently imitative of Planema Aganice (Hewits.),i 

 the shape and position of the central bands, the colouring, and particularly the 

 basal markings of the under side of the hind-wings, being remarkably similar ; 

 but the Pseudaercea has a short subapical white bar not found in tlie Planema. 

 The latter marking is, however, not noticeable in flight, and I fully believed 

 the flrst example that I met with to be Planema Aganice, — a butterfly 

 frequenting the same spot. Curiously enough, the ^ Tarquinia does not 

 resemble either sex of PI. Aganice, but is plainly modified in imitation of 

 Amauris Echeria (Stoll), as shown by the reduced spots and (especially) apical 

 prolongation of the fore-wings, the ochreous-yellow band of the hind-wings, the 

 more distinct series of small submarginal spots, and the browner colouring of 

 the under side. I have not seen the 5 Tarquinia in life, but the likeness to 

 Echeria in the cabinet is so strong, tliat on the wing it is in all probability 

 entirely deceptive. 



I met Avith two cxam])les only in Natal, one near D'Urban, on iSth February 

 1867, and the other near Verulam, on the 24th of the same month; the former 

 was settling on a shady pathway in a wood, and the latter hovering about young 

 trees at the edge of a wood, and settling on the outermost twigs occasionally. 

 This latter individual had precisely the same slow floating flight as Planema 

 Aganice, and settled in exactly the attitude adopted by that butterfly and by 

 Amatiris Echeria, viz., with the wings dependent and closely shut, at the very 

 extremity of a twig. 



The butterfly is undoubtedly rare ; but the late Mr. M. J. M'Ken forwarded 

 a male from D'Urban in 1869 and a female in 1871. A female from Natal 

 ■was in Mr. Hewitson's collection in 1867, as well as a male from the Zambesi. 

 During his stay in Natal, Colonel Bowker has sent me four males from D'Urban 

 (April 1879 ^^^"-^ June 1881), one male from Isipingo (April 1879), and two 

 males and one very small female (exp. al., 2 in. 4^ lin. only) from Pinetown. 



In Mr. Distant's collection I noted an apparent (J from Magila, East Africa, 

 in which the bands were tinged with reddish-ochreous. The Natalian ^ s vary 

 in the more or less yellowish tint of the band of the hind-wings.

1 The West-African Lucretia, with its much more conspicuous subapical white marking 

 in the fore-wings, bears a strong likeness to Planema Lycoa (Godt.), a native of the same 

 region.
