life. The apparent colour varies from blue to green with the 

 background." 



Mr. Neave wrote again a few days later: "I have had a 

 look at the B.M. series, and it seems probable that examples 

 from the drier parts of Africa are mainly of the blue type as 

 compared with the greener ones from more humid localities. 

 I am not sure that the point is of great importance, though 

 the apparent colour in the Amauris models varies with back- 

 ground, being greener in shade and amongst vegetation and 

 bluer in bright sunshine ; they would therefore appear more 

 often of the latter colour in drier and more open situations 

 in which, however, they are comparatively rare."' 



Capt. Carpenter continues : " Papilio (Cosmodesmus) pylades 

 angolanus, Goeze, abounds : it is a curiousdooking thing on the 

 wing, and sometimes as it dashes past has rather a Pierine 

 appearance. P. demodocus, Esp., is common. I have seen a 

 $ P. dardanus, Brown; somehow it looked slightly different 

 from the forms I knew on the islands in L. Victoria, and I 

 am wondering whether it also is from the south [probably 

 the Eastern form with a much heavier submarginal black 

 band to hind-wing]. It will be interesting if I can get a 

 female, for since I came here in October I have not seen a 

 single species of its models, and I have collected almost 

 every day. Presumably cenea [probably hippocoon, F. | would 

 be the commonest form. These five are the only Papilionines 

 I have met as yet. 



" Pierinae. — I know so little of the names of these that I 

 cannot say much about them. Belenois and Catopsilia (the 

 thing like a Brimstone) are not very common — I haven't 

 seen either Eronia I edit. Boisd., or cleodora, Hiibn., here. 

 A Tcrinx of a form strange to me \T. regularis, But!.; see 

 pp. cl, cli| is plentiful, and a few fine large Teracolus [T. casta, 

 Gerst.] not uncommon, but the feature of the Pierine fauna 

 is a magnificent large, fragile, pure white species with steely 

 purple tips to fore-wing [Teracolus regina, Trim.]. It is of 

 extremely powerful flight and is very shy, and therefore 

 almost impossible to catch except when lulled by clouds or 

 in the evening. 



" Of Nymphalidae there are some good species. It is a
