the mistake as regards motozi by stating that the male differs 

 scarcely at all from the female except in being darker on the upper- 

 side, and having smaller and more separate yellow markings on the 

 underside.

Three examples from Christmas Pass, captured respectively on 

 15th, 17th, and 27th February. They are rather larger than the 

 West-African specimens that I have seen, expanding 1 in. 6| to 

 Ik lin., and the discocellular fulvous-yellow spot on the upperside 

 of the hind wings is absent in two of the specimens and only just 

 indicated in the third; on the underside this spot is faintly marked, 

 and the other yellow spots (apart from the large discal hind- 

 marginal patch) are also very much reduced and in two examples 

 obsolescent. On both surfaces the large fulvous-yellow patch of 

 the hind wings differs in each specimen both as to shape and size. 



1 have found this species recorded from numerous localities 

 along the West Coast, from Assinie (in about 5° N. lat., and 3° 

 W. long.) as far to the south as Angola ; but Mr. Selous's 

 captures give the first instance known to me of its occurrence in 

 East Africa — unless Shoa in Abyssinia be one (see C. Oberthiir, 

 Ann. Mus. Civ. (xenova, xv. p. 733, 1883). Mr. Selous describes 

 the Butterfly as scarce : he found it settling on low bushes in 

 shady places and so alert as to be caught with difficulty. 



160. Pterygospidea flesf/s (Fabr.) 2 . 



Papilio flesus, Fabr. " Sp. Ins. ii. p. 135. n. 621 " (1781) ; Ent. 

 Syst. iii. 1, p. 328. n. 286 (1793).

The eight examples from Christmas Pass and one of the two 

 examples from the Mineni Valley are remarkable for the complete 

 and unvarying development of the entire discal series of black or 

 brownish-black spots on the underside of the hind wings, — a series 

 so variable in Natal specimens that it is by no means uncommon 



1 Pardaleodes fuJgcns, Mabille (Bull. Soc. Zool. France, 1877, p. 236), from 

 the detailed description given, does not seem to be separable from Pt. galenus. 



2 In S.-Afr. Butt. iii. p. 365, I explained how from M. Mabille's description 

 (Ann. Soc. Ent. Fr. (5) vi. p. 272. n. 21, 1876) I was disposed to consider that 

 Tagiades insularis, Mab., from Madagascar, was probably not separable as a 

 species from P. flesus. Having since been favoured by M. Mabille with two 

 males of his T. insularis, I have, however, come to the conclusion that the 

 Malagasy Butterfly may be held distinct from the Continental species, as 

 besides the smaller size and the straighter hind margin of the hind wings 

 (which M. Mabille points out in vol. i. p. or>4 of the Lepidoptera in Grandi- 

 dier's 'Madagascar, &c.'), I find that on the underside of the hind wings 

 there is a very much broader and complete hind -marginal brown border from 

 the radial norvule as far as the submedian nervure.
