in the ocelli. Even sliglit variations are rare in this remarkably 

 constant species. 



" Blues " were fairly numerous though of few species; Polyommatus 

 hpeticus, L., and Tarn ens tlieophrastus, F., were both abundant, the 

 first especially in bean fields, the second about Acacia bushes, or at 

 flowers of Mrva. I fancied that a male of the first named butterfly 

 had a slight scent lilve meadow-sweet, while one of the latter had a 

 moderately strong, sweet, luscious odour. Of Azanus vhaldus, Cram., 

 I took half-a-dozen, having previously come across a female in Nubia 

 at Aniada (Lat. 20° 45' N.). Of the little Chilades trochilus, Frey (a 

 species also met with at Aswan), I took one only. 



Zizera h/simo7i, Hiib., was commonest on weeds in fields from 

 which a crop had been removed, especially frequenting Mrva and 

 Arnehia. On the other hand Catoehryso2)s eleusis, Dem., was common 

 about small, low-growing, white-prickled Acacia bushes on the edge 

 of the desert. The Khartum males were markedly bluer, less violet, 

 than tlie Aswan specimens, which latter were chiefly taken about 

 a pink-flowered Lotus. 



Moths were not very numerous, but many of those taken 

 were interesting. 



The almost cosmopolitan UtetJieisa pidcliella, L., was fairly 

 common on both sides of the town. The little Pyrale, Noctuelia 

 floralis, Hiibn. (which is like an " improved " Herhula cesintalis, 

 Schiff.), occurred at the flowers of Arnehia sp., and the handsome 

 Deilephila livornica, Esp., was taken at about 11 a.m. one hot sunny 

 morning hovering at the flowers of Echium sp., both Hawkmoth and 

 flower being in this case quite Palsearctic. All my other moths were 

 victims of the seductive attractions of the electric lights. On some 

 evenings, when the north wind was not too strong, these were much 

 frequented, and while boxing moths on such occasions crowds of small 

 flies entangled themselves in my scanty hair in a most irritating way. 

 Amongst the moths D. livornica, Esp., turned up again, with it was a 

 singidar pale rjrey Syntomid, Apisa canescens, Walk. ; also several 

 Geometrids, including Craspedia consentanea. Walk, [which I also 

 took at Dakkeh, 23° 15' N., and even as far north as Luxor, 25° 50' N.] ; 

 a very worn Tephrina, probably disputaria, Grn., var. ; four specimens 

 of Peridela sudanata, Warr. and Eoth. ; * also an " Emerald " which 

 Mr. L. B. Prout says is a new Chlorochroma, as so often happens a
