distant from the others which are parallel ; pterostigma whitish, 
enclosing four strong black nervules, of which the outer is forked 
at the end ; poststigmatic area in the anterior wings, consisting of 
a lower row of 5 large cellules and an outer row of 10 or 11 small 
cellules, with one or two cellules interposed, in the posterior the outer 
cellules are larger, and there are apparently no interposed cellules. 
Length of body without appendages, 10 mm. ; length of append- 
ages, 6.5 mm. ; length of anterior wing 29 mm. ; greatest breadth of 
same, 7.5 mm. ; expanse 60 min.

Very distinct from B. hamatus, Klug, and B. agrioides, 
Rambur, (which appear to be closely allied) by the com- 
paratively broader wings, the colours of the body, and the 
distinctly white costa and subcosta, and still more so by 
the character of the f appendages, which although 
formed after the same plan, differ greatly in details, such 
for instance as the outer curve which causes them to 
enclose a nearly circular space, and especially in the 
branch formed at the point of geniculation, there being 
only a rounded tubercle at this point in the species just 
alluded to. 
The species figured in Savigny’s “Déscription de 
Egypte,” pl. 3, fig. 2 (1) cannot belong here, neither do 
the appendages accord with those of the other species 
unless they were distorted in some way. 
The Bubo hamatus noticed and figured by Lucas in 
the Pane scientifique de l’ Algérie,” Insects, p. 137, 
pl. ii, figs. 5 and 54, cannot pertain here, nor can it 
ee to the same genus, Inasmuch as the gf has no 
prominent appendages. Probably it is a Stphlocerus or 
allied thereto. JI have more than one species (at present 
undescribed) from Algeria that should perhaps be placed 
in that genus. 
Bubopsis gravidus, sp. n. 
Blackish, varied with piceous, clothed with long and dense cinereous 
hairs on the face, vertex and underside of thorax, and with short 
and sparse cinereous hairs on the thorax above ; face ochreous yellow, 
back of head brown ; antennee much shorter than the wings, black 
up to the short and thick club, which is wholly yellowish ; thorax 
varied with reddish piceous above and on the sides; legs wholly 
reddish yellow, the tarsal articulations scarcely blackish, claws
