quite Palaearctie. All my other moths were victims of the seduc¬ 
tive attractions of the electric lights. On some evenings, when 
the north wind was not too strong, these were much frequented, but 
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 turned up again, with it was a singular pale grey 
Syntomid, Apisa canescens, Walk.; also several Geometrids, including 
Craspedia consentanea , which I had taken at Dakkeh, and even as far 
north as Luxor; a very worn Tephrina, probably disputaria , var.; 
four specimens of Peridela sudanata, Warr. & Eothsch.; 1 also an 
“ Emerald,” new to science, which Mr. L. B. Prout has described for 
the next part of his contribution to Wytsmann’s Genera Inseetorum, 
under the name Prasinocyma sanguinicosta, sp. nov. ; as so often hap¬ 
pens with novelties, a unique example. There was in addition a male 
specimen of a Lymantriid which Sir George Hampson has described 2 
as Porthesia erythrosticta, sp. nov. [Plate V., Eig. 7]. He says it resembles 
Euproctis rufopunctata, Walk. The Noctuae were more remarkable 
than numerous ; several specimens of Caradrina exigua, whose larva 
feeding on cotton, barsim (a kind of clover), and Hibiscus, is quite a 
plague to the farmers of modern Egypt; a female of Euxoa spinifera, 
another common Egyptian moth ; four specimens of Sesamia cretica ; 
one of S. apunctifem, Hmpsn., the latter very distinctly marked, 
more so than any in the National Collection. Another cotton pest 
of Egypt, Prodenia litura, Fabr. ( littovalis , Boisd.), was represented 
by a single example. One of the most unexpected visitors was 
Copicucullia sublutea , Graes. [Plate V., Fig. 9] ; the type of this species 
came from Eastern Turkestan, and the British Museum possesses but 
a single example, and that from the desert of Gobi in Northern 
China, no less than 30° N. and 70° E. of Khartum! Sir George 
Hampson thinks that desert insects probably have an unusually 
wide range, since desert conditions are similar over very large areas 
(a remark that applies with almost equal truth to areas long under 
cultivation). Of Spodoptem mauritia, two specimens turned up; of 
the common and very active Quadrifid, Acantholipes affinis, Butl., 
only one. Of a Catocaline, which is probably a new species of 
Hypoglaucitis, I took two, and Mrs. Longstaff another; a specimen of 
the same moth came to the lights of the steamer at Kasr Ibrim, in 
Nubia, on January 29th. 3 As might have been expected, there were 
plenty of Pyrales among the frequenters of the lamps: two Galleriids,
