Hab, One highly mature 2 from Azazga, 6th Sept., 
1898, at ight in the inn. 
It is scarcely possible that this can be the 2 of the 
preceding species, neither can it pertain to B. hamatus or 
agrioides, 
Ascalaphus ictericus, Charp. 
Hab, Constantine, 17th and 18th May 1895. A wide- 
spread species in Algeria. 
NEMOPTERID. 
Halter barbarus, Klug (Nemop. al girica, Rbr.). 
Hab. Ain Kriar, 22nd June, 1896, on sandy ground 
in the “scrub” near the W. base of Djebel Ouast. Mr. 
Eaton remarks :—“ Common at La Calle near the sea, 
especially on the hill W. of the town.” <A well-known 
Algerian species. 
I have recently described (Bull. Soc. Ent. France, 1898, 
p- 169) a small species of this Family under the name 
Croce chobauti from Ghardaia in South Oran; and M. 
Brongniart has recorded the occurrence of Halter (?) 
imperatriz, Westwood, from somewhere in the same district 
(Bull. Mus. Paris, 1896, p. 30), which is very remarkable 
if his identification be correct, the species belonging to 
tropical West Africa.
