I follow Mr. Trimen in disregarding the somewhat forcible plea 

 of Prof. Aurivillius for the identification of Latreille's species with 

 the Papilio niso of Linnaeus, and the substitution of the latter 

 name. The copies of Clerck's figures given by Prof. Aurivillius do 

 not carry conviction with them. They may apply to several other 

 obscure African forms as well as to the species named by Latreille, 

 and the description given by Linnaeus is wholly inadequate. We 

 shall for ever be in the dark as to the species intended by Linnaeus. 

 The identification defended so learnedly by Prof. Aurivillius lacks 

 altogether that positiveness which in such a ease is essential, and 

 is at best merely opinionative. In letters and orally Mons. Mabille 

 has stoutly maintained to me the identity of Latreille's species 

 H, hottentota with the species recently described by Mr. Trimen 

 under the name obumhrata (see p. 59). The females of O. ohumbrata 

 are positively undistinguishable from the females of 0.hotteniota,&adi 

 I am inclined to think that the form characterized by Mr. Trimen 

 is a dimorphic variety. Typical males of O. hottentota and males 

 of the form ohumbrata are found in my collection, having been 

 taken on the sume day and in the same locality in coitu with
