on the under-side of the hind wings are edged with black, 

 this black edging being often visible on the upper surface. 

 Klug makes no mention of this black edging, which I am 

 disposed to associate with the heavy rainfall at Port Sudan 

 a few weeks before my visit, whereas Khartum was suffering 

 from drought. Mrs. Watertield wrote to me when I was at 

 Khartum saying that butterflies had been much more plentiful 

 since the rain, and more strongly marked. 



Teracolus pleione is another of K lug's species, the types 

 coming from " Arabia Felix," whatever that geographical 

 expression may mean. 



Petherick took it on the White Nile, and Mr. W. S. L. 

 Loat in 1901 took a female at Kaka on the same river in 

 Lat. 10° 40' N. In February last I myself took two females 

 near the same village. Colonel Yerbury found it at Aden, 

 apparently in some numbers. Colonel Swinhoe (Proc. Zool. 

 Soc, Lond., 1884, p. 436), says : "Of this very rare species 

 I have a series from Aden." However, Mrs. Waterfield looks 

 upon it as one of the commonest butterflies in the Park, at 

 Port Sudan. This park is little more than a piece of the 

 desert scrub which has been railed in. On and about certain 

 shrubs, a species of Cleome (Nat. Ord. Cupjuiridaceae), T. 

 pleione was so plentiful that I repeatedly had several in my 

 net at once. A few turned up north of the harbour near the 

 shore, but I did not meet with it in the desert to the west or 

 south of the town. It is evidently a far more local insect 

 than its near ally T. haUmede, Klug. 



It should be noted that the females from the White Nile

differ from those taken on the shore of the Red Sea by 

 approximating in colour to the males. 



Colonel Yerbury observed that the yellow 9 9 of Teracolus 

 pleione were much brighter at Aden than those now exhibited. 



East African Asilids and Kuopalockra. — Mr. S. A. Neave 

 exhibited some specimens of the Asilid genu> I/i/jn'rechia, 

 representing three, perhaps four, species, all taken during his 

 recent tour in Kast Africa. He also showed for comparison 

 four common species of Xylocopa, bees to which the flies bore 

 a marked superficial resemblance. These flies were usually
