1881.] MR. A. G. BUTLER ON LEPIDOPTKRA FROM SOCOTRA. 1/5 



Picarise, and Colunibae, as being of wide distribution, we find that 

 out of the twenty birds of these three orders, all but seven are 

 mentioned in Heuglin's ' Ornithologie Nordost-Africa's.' Of these 

 seven, six, as far as is at present known, are new species pecuHar to 

 the island ; but one is a Western Asiatic species, although very 

 closely allied to a prevailing North-east African form. Of the si\ 

 new species, one seems to be generically distinct from any thing yet 

 known, though our impression is that Rhynchostruthus will yet be 

 found on Cape Gardafui. The remaining five all belong to prevailing 

 North-east African genera. 



2. Oil the Lepidoptera collected in Socotra by Prof. I. B. 

 Balfour. Bv Arthur G. Butler, F.L.S. F.Z.S. &c. 



[Keeeived January 1.5, 1881.] 

 (Plate XVIII.) 



The Lepidoptera collected by Professor Balfour consist of 24 

 specimens referable to 13 species, of which 11 are Rhopalocera; 7 of 

 the species are new to science. 



Of the known forms in this series one is cosmopolitan, two are 

 found in Euiope, Asia, and Africa, one throughout Africa, one in 

 S.AV. Africa and Abyssinia, and one (with trifling differences) in South 

 Africa. Of the new forms five are allied to previously recorded types 

 from the following localities — one from the Comoro Islands, one 

 from S.W. Africa, one from Zanzibar, and two from Arabia. With- 

 out the help of these last two, it would therefore be impossible for 

 any one not acquainted with it to guess at the locality from which 

 this collection had been obtained. 



The following is a list of the species : — 



RHOPALOCERA. 



NvMPHALIDJi. 



Danais chrysippus (No. 706). 



Fapilio chrijsippus, Linneeus, Mus. Lud. Ulr. p. 263 (1764). 

 A single female specimen of this widely distributed species was 

 obtained. 



Calysisme socotrana, sp. n. (Plate XVIII. fig. 7.) 



(c? No. 731, ? 716.) 



Nearest to C. umjnana from Johanna^Comoro group). Olive-brown ; 

 wings above with i)aler outer border traversed by a wavy submarginal 

 brown line ; a black marginal line ; fringe slightly darker than the 

 outer border : primaries crossed beyond the cell from costa to first 

 median branch by a slightly undulated pale-bordered dusky line ; 

 two ocelli of the "ordinary type, one towards apex about a quarter 

 the size (?'. e. half the diameter) of the other, which is placed on
