The only three spécimens known from Egypt of this species 

 are : one in the collection of the Ministry of Agriculture labelled 

 "Coll. Willcocks. 11.1912. Egypt ? " and two in the Sultanic 

 Agricultnral Society Collection, both labelled "from ? dates stored 

 — Gizeh, Nov. 1912." This last data must be an error, for Mr. 

 Willcocks * States that his spécimens were bred from pupae found 

 in a pièce of wrapping paper which he was given one day in 

 November 1912 at Gizeh by Mr. T. Brown to wrap up some spéci- 

 mens he had collected. What the spécimens were he does not remem- 

 ber but he déclares that they were not spécimens which could harbour 

 the olive fruit flv. He further states that the pupae were not ob- 

 served until the parcel was opened in the laboratory and then thev 

 were found attached to the ]:)aper wh.ere it had been folded. The 

 paper in question had been taken out of a room in which variou?; 

 fruits had been stored but Mr. Willcocks was unable to ascertain if 

 Egyptian olives had been ke]it there.
