THE WHITE NILE 
419 
That night we slept at Koseires (not to be confounded with the 
place of the same name on the Blue Nile). Here again insects came 
to light, viz.: Cirphis loreyi, as before; the ubiquitous Nomophila 
noctuella ; a yellowish Arctiid, superficially rather like a Nonagria, 
not known to Sir George Hampson; another specimen of the new 
Antarchaea previously taken at Kosti; a Lymantriid which Sir 
George Hampson considers to be the male of an undescribed female 
from British East Africa, and has described as Laelia seminuda, sp. 
nov} [Plate V., Eig. 6.] With the moths came the Acridian Oxycory- 
phus compressicornis, Latr. The next morning a Mantid, Calidomantis 
savignyi , Sauss., was found on a water-lily on the breakfast table; 
doubtless it had been attracted by the lights the night before. 
Several Beetles also visited the lights-—which, by the way, were 
acetylene, and not very brilliant:— Coccinella rufescens , Muls.; 
Brachinus sp.; Ora sp.; Tanymecus sp. (the same as at Kosti); 
Paederus sp. ; and Ghlaenius sp. 
The next morning we left Hillet Abbas at 10.30 a.m.; it is a 
bare, miserable place, not improved entomologically by a tearing 
wind. However, besides three Dragon-flies, I managed to get hold of 
one Azanus ubaldus, a female ; a female Teracolus daira ; and two 
males of T. halimede. This last is a delicate insect, white with a 
cadmium-yellow flush; it appears to have a slight, somewhat dis¬ 
agreeable scent. Here I missed a Blue, probably Polyommatus 
baeticus. 
On our way down stream again I got a short 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, and a 
male Danaida chrysippus ; 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 charac¬ 
teristic scent. 
The flowers of Carrot yielded a female of the Scoliid Elis senilis , 
of which I had taken several males at Khartum. When I first met 
with this in Egypt I had no notion that the sexes were conspecific. 
The male, very variable in size, is smaller, its abdomen orange-red, 
ringed with black, its head and thorax clothed with grey pubescence 
(whence the name), its wings are nearly transparent. The female is 
larger and stouter: the pubescence orange, abdomen blue-black, and 
about 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
