THE SUDAN 
Hampson with obsoleta, King. My Egyptian specimens quite agree 
with those in the British Museum from Cairo, but the two from 
Kosti are identical with three from the Blue Nile, and differ from the 
others in being smaller, darker, and of a blue-grey instead of a red¬ 
dish tint. Mr. G. T. Bethune Baker has since described this form as 
Trichiura definita , sp. nov. 1 [See Plate V., Eig. 3.] Then there was a 
little ochreous Noctuid, a species of Antarchaea, which is not in the 
British Museum, also a very distinct Lymantriid, a tiny moth nearly 
black, with an orange, black-spotted abdomen, which Sir George 
Hampson has described as Euproctis xanthosoma, sp. nov., adding 
“ very distinct from all other species known to me ” 2 [See Plate V., 
Fig. 4]; also a Schoenobius and a Ghilo , both of which appear to be 
new. With these novelties were the less remarkable Endotricha 
consohrinalis, Zell., and the very generally distributed Hypsopygia 
mauritialis, Guen., a species near the British Pyralis costalis, Fabr. 
It is curious in how many places and under what different 
circumstances I have taken single specimens of Acridium aegyptiacum ; 
here it came to light, accompanied by other Acridians and Crickets 
(not yet named), as well as by the Mantid, Empusa egena, Charp., 
and the Cockroach, Derocalymma porcellio, Gerst. 
The huge, but dingy Water-bug, Limnogeton fieberi, Mayr, was 
accompanied by a number of Beetles, many of them obscure species 
that I have been unable to identify :— Opatrum subsulcatum, Eeich., 
in some numbers; Opatrum sp.; Tanymecus sp.; Taeniolobus sp.; 
Ghlaenius sp.; Paederus sp.; Luciola sp., not in the British Museum; 
and lastly a male of the common Ant, Myrmecocystus viaticus. 
At our most southerly point, Gebel En (lat. 12° 40' N.), 208 miles 
from Khartum, I had a very short time for collecting. The thin 
scrub was extremely dry, there was scarcely any herbage, 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 dis¬ 
concerting. 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, with the usual scent, differed from the 
type only in having the veins of the hind-wings margined with 
white; of two Teracolus halimede one had a large piece missing from 
a hind-wing; there were two T. eupompe, Klug; and, lastly, a T. 
evarne, Klug, the only specimen that I met with. All these Teracoli 
were males, and the two last-named species decidedly of dry-season 
type.
