Mautid, Calkin ma at is saiugniji, Sauss., was found on a water-lily on the 

 breakfast table ; doubtless it had l)een attracted by the lights the night 

 before. Several beetles also visited the lights — which were acetylene 

 and not very brilliant — Coccinena rnfescens, Muls. ; Brachinvs sp. ; 

 Ora sp. ; Tanymecvs sp. (the same as at Kosti) ; Pmderits sp. ; and 

 Chlsenins sp. 



The next morning we left Hillet Abbas at 10.30 a.m., a bare, 

 miserable place, not improved entomologically by a tearing wind. 

 However, besides three dragon-flies, I managed to get hold of one 

 Azanus ubaldtis, Cram., a female ; a female Teracohis daira, Klug ; and 

 two males of T. halimede, Klug, var. leo, Butler. This last is a 

 delicate insect, white with a cadmium-yellow flush ; it appears to have 

 a slight somewhat disagreeable scent. I missed a Blue, probably 

 Polyommatus hpeticus, L. 



On our way dowTi stream again I got three quarters of an hour's 

 collecting at Kosti in a small vegetable garden close to the landing 

 place. Only two butterflies rewarded my efforts, a male Zizera 

 lysimon, Hiibu., and a male Dauaida chrysijpjms, L., the last, taken at 

 onion flowers, was almost typical, with merely a little white along the 

 veins of the hind- wings. It proved tenacious of life and had the usual 

 characteristic scent. 



The flowers of carrot yielded a female of EUs senilis, F., a ScoHid 

 of which I had taken several males at Khartum. When I first met 

 with this in Egypt I had no idea that the sexes were conspecific. The 

 male, very variable in size, is smaller, its abdomen orange-red, ringed 

 with black, its head and thorax covered with grey pubescence (whence 

 the name), its wings transparent. The female is larger and stouter: 

 the pubescence orange, abdomen l)lue-black, and abovit two-fifths of 

 the wings purple. On the same flowers I took the beautiful Eumenes 

 lepelletieri, Sauss., one of each sex, a fine yellow insect with a black 

 cross on its abdomen; a pair of the yellow-eyed Tachys^'hex ftuctuafits, 

 Grerst. ; a male of Odynerus (?) bellatulus,Siinss.; also a Pompilid which 

 puzzles Mr. Morice, but which he thinks may be Salius hretonii, Guer. 

 With these was an Egyptian grasshopper, Chrotoyonins liignhris, 

 Blanch. 



We stopped at Tawila (185 m. al)Ove Khartum) to till up with fuel. 

 Fortunately the process of " wooding " was a slow one and I got ashore 

 from 1.0 to 4.30 p.m. The terrain was covered with a scanty scrub 

 just above the level of the river ; the small trees were mostly acacias, 

 but all were exasperatingly thorny. Collecting was good, in spite of
