1884.] LEPIDOPTERA FROM ADEN. 485 



17. DeUDORYX LIVIA. 



Lyccena livia, Klug, Symb. Phys. pi. 40. figs. 3-6 (1834). 



Aden, 25th December, 1883 ; 5th, 6th, and 20th January, and 

 17th February, 1884. 



The female of this species (of which Klug figures two males) 

 closely resembles the Dipsas antalus of Hopffer, two females of 

 which are evidently represented as sexes.

Terias chalcomiceta, Butler, Ann. & Mag, Nat. Hist. ser. 5,

Lahej, 3rd and 6th April ; Haithalkim, 4th April, 1884. 



The seven examples forwarded by Major Yerbury are separated 

 by him under four different numbers, probably on account of their 

 difference of size and the more or less pronounced character of the 

 markings on the under surface ; in some specimens these are as 

 sharply defined as in T. cBsiope, whilst others agree with the type 

 from Johanna in almost every particular. 



The Catopsilice of the collection appear to repeat, to a certain 

 extent, the peculiarities of the forms of Limnas, since they are un- 

 doubtedly connected by intergrades in such a manner as to render 

 their separation very difificult. 



When I published my Monograph of Oallidryades, I recognized 

 two African types, Catopsilia pyrene and C. fiorella, which, at the 

 time, were believed by Mr. Trimen to be dimorphic forms of one 

 species ; this belief was based upon the capture of a supposed 

 C. pyrene S in coitu with a 0. fiorella $ : his words are as 

 follows : — " On one occasion near Durban, Port Natal, I took a 

 white c? and yellow $ in copuld. Females of the paler colouring 

 are certainly scarcer than the others ; but Mr. Bowker writes that 

 he has noticed them in Basuto-Land, and Mr. Hewitson possesses 

 one from Madagascar, which resembles the yellowish-white specimen 

 from Bourbon, figured in M. Maillard's ' Notes sur I'lle de la 

 Reunion (Bourbon),' published in 1862." 



The pale female in Mr. Hewitson's collection is my G. rufo-sparsa, 

 and differs from C. fiorella not only in its pale colouring, but in 

 the total absence of the angular subapical series of spots on the 

 primaries, the shorter secondaries, the ochreous instead of chrome- 

 yellow colouring of the under surface, the denser and less striate 

 character of the reticulate markings, and the suffused ill-defined 

 character of the discal series of spots. 



In a collection received some years since from Abyssinia were 

 great numbers of a Catopsilia which I took to be C. fiorella, and 

 one of these I selected for the saTie of its locality. On setting it, 

 however, I found it so distinct — the central area of the wings b"ein» 

 occupied by a broad white belt, and the under surface of the second- 

 aries showing only one instead of three silver spots — that I concluded 

 to describe it as a new species under the name of 0. aleurona.
