from all other species known to nie "* ; also a Schoenohius and a Chilo, 

 both of which appear to be new. With these novelties were the less 

 remarkable Endotricha consohrinalis, ZelL, and the very generally 

 distributed Hyjjsopygia mauritialis, Gn., a species near the British 

 Pyralis costaUs, Fab. 



It is curious in how many places and under what different circum- 

 stances I have taken single specimens of Acridium, ivgyptiacum, L. 

 Here it came to light, accompanied by other Acridians and crickets (not 

 yet named), as well as the Mantid Ein[nisa egena, Charp., and the 

 cockroach, Derocalymma porcellio, Gerst. 



The huge biit dingy water-bug, Lininogeton fieberl, Mayr, was 

 accompanied by a number of beetles, many of them obscure species that 

 I have been unal)leto identify : — Ovatrum svhs'idcatum, Eeiche, in some 

 numbers ; Opatrum sp. ; Tanymecus sp. ; T^eniolohus sp. ; ChLvmius 

 sp. ; Pxderus sp. ; Luciola sp., not in the British Museum; and lastly 

 a male of the common ant Myrmecoeystus viaticus, Fab. 



At our most southerly point, Gebel En, Lat. 12° 40' N., 238 m. 

 from Khartum, I had a very short time for collecting. The thin scrub 

 was very dry, there was scarcely any heritage, and but one or two 

 shrubs were still in flower. The heat was intense, 114° F. in the shade, 

 at the same time the sense of hurry was most disconcerting. Under 

 these adverse conditions all that I succeeded in taking back to the ship 

 were two dragon-flies and six butterflies. A male Danaida chrysippus, 

 L., with the usual scent, differed from the type only in having the 

 veins of the hind-wings margined with white ; of two Teracolus halimede, 

 Klug, one had a large piece missing from a hind-wing ; two T. 

 eu'pompe, Klug ; and, lastly, a T. evarne, Klug, the only specimen that 

 I met with. All these Tern col I were males, and the two last named 

 species decidedly " dry." 



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. : — Crrphls loreyi, Dup., as before ; the ubiquitous NomojiliilO' 

 nocfueJJa, Schiff. ; a yellowish Arctiid, superficially rather like a Nona- 

 gria, not known to Sir George Hampson ; another specimen of the new 

 Antarchiea 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 Lxlia semimida, sp. n.f ; and 

 the Acridian Oxycoryphus compressicornis, Latr. The next morning a
