secured no less than eighteen males and nine females. 

 My Port Sudan specimens may be distinguished from those 

 taken near Khartum by the greater development of the 

 black markings, and more especially by the orange veins 

 on the undersides of the hind-wings being edged with black. 

 I associate this greater strength of coloration [not present 

 in King's types] with spring rains reported by Mrs. Water- 

 field as having fallen at Port Sudan, but which did not 

 occur at Khartum. 



The above are all the records that I have come across. 

 Boisduval [Sp. Gen. der Lepid., vol. i, sp. 581] only quotes 

 Klug. 



I have httle doubt that this butterfly is attached to 

 the Desert Caper, Capparis aphylla, Roth., a leafless bush 

 with bluish-green stems and inconspicuous flowers with 

 red stamens. 



Three males appeared to have a faint sweet scent, 

 suggesting in one case Gorse.

carnifer, Butler). 



King's types came from Ambukol, and from " Arabia

Dunn took it on the Bahr al-Zarafa. ' 



In 1909 I took two at Tawila, and in 1912 I captured 

 in all twelve specimens at various points on the White 

 Nile from Tawila in Lat. 13° 16' N., up to Kanisa in Lat, 

 6° 50' N., half my specimens coming from the latter place. 



Col. Yerbury found it one of the commonest butterflies 

 at Aden, where its larva feeds on the Salvadora persica, 

 Linn. [Nat. Ord. Salvadoraceae]. 



It has a wide range in Africa — Abyssinia, Somaliland, 

 Victoria Nyanza district, British East Africa, German. East 

 Africa, the Congo, Damaraland, Angola ; in Asia it is found 

 in Arabia, Persia, Sind and North-west India ; but in 

 Southern India it gives place to T. amatus, Fabricius. 



43. Teracolus phisadia, Godart ( = arne, Klug). 



Klug recorded this from Ambukol as well as from 

 " Arabia deserta." 



Capt. Dunn took it on the Bahr al-Zarafa. Loat took
