68 MR. R. TRIMEN ON BUTTERFLIES FROM [Jan. 16, 



that, of Mr. Selous's five specimens, two have this feature more 

 developed than in the figure of T. lasti, one has it about the same, 

 one has it considerably less, and in the last (in which the fore-wing 

 border is abnormally broad) its only trace is some sparse black 

 scales. As pointed out in my description of this species (S.-Afr. 

 Butt. ii. pp. 211-212), the fuscous markings of the upperside are 

 variable in the Natalian typical form, and this tendency seems 

 more marked farther to the north-east.

 (1866). 



Tour examples from the Mineni Valley and ten from the Vunduzi 

 Eiver. Noted as always found in shady forest, flying very slowly, 

 and towards sunset settling very often. 



The locality of the type is given by Hewitson as the Zambesi, but 

 in Mr. Kirby's Catalogue of the Hewitson Collection (1879, p. 180) 

 the three specimens recorded are respectively from " Gaboon, 

 Calabar, and Lake Nyassa," showing a very wide range for the 

 species. An example received from the Eev. H. Junod was taken 

 at Morakwen, Delagoa Bay, on 30th March, 1891 ; it is the only 

 one known to me from an extra-tropical locality. 



There is little or no variation observable among Mr, Selous's 

 specimens, and the sexes differ only in size. 



I find this Butterfly, as well as its close ally P. peuceda (H. G. 

 Smith), from Mombasa, and P. muhata, Dewitz, from Mukeuge and 

 Cameroons, inseparable generically from P. abraxas and P. trojncalis, 

 and do not see on what grounds Messrs. Kirby and Smith (op. cit. 

 Lycsen. Afr. pis. ii. & ix. pp. 3 & 37) have placed them in 

 Butler's genus Larinopoda (Trans. Ent. Soc. Lond. 1871, p. 172), 

 the type of which presents a •«'ide difference from them both in 

 palpi and neuration.

Eifteen specimens were taken in the Mineni Valley from the 9th 

 to 27th March, and two at the Lusika Eiver on 1st April ; four from 

 the former and one from the latter locality are females. Mr. 

 Selous notes that this Butterfly was of very slow flight, and congre- 

 gated in numbers on the stems of a tall herbaceous plant with blue 

 flowers. 



The males agree fairly with the figure above cited,which represents 

 an example from Ashanti, but on the upperside are of a slightly 



^ In op. cit. p. 46 (1890) Messrs. Smith and Kirby note that T. (?) hi/dcffarda 

 may be inchicled iu the genus Durbania.
