156 Mr. R. McLachlan on 
the disk, and occasionally the subcosta is faintly marked with fuli- 
ginous, network rather open, pterostigma opaque yellowish, wing- 
roots yellow. 
Length of body ¢ (with appendages) 17—21 mm., 2 17—21 mm. 
Expanse 36—40 mm. 
Hab. Biskra, May and June, 1894, also Méchéria, South 
Oran (L. Bleuse), about 18 examples in all. Two f from 
Ain Séfra, South Oran, differ slightly in having the 
neuration nearly wholly fuligmous, but not otherwise. 
This small species should be allied to I. linearis, Klug, 
from Syria, but can hardly be identical therewith, differ- 
ing especially in the markings of the pronotum according 
to the description. 
I direct attention to the long hairs on the posterior 
femora of the ~ mentioned in the foregoing description. 
These are present, and even in a more marked degree, in 
several undescribed species, and they probably exist in 
some already described, but they are wanting in the two 
larger species—I/. appendiculatus and M. bilineatus. 
Myrmeleon oulianini, McLach. 
Hab. Biskra, 2nd June, 1894,2 ¢. I have alsol 9 
from Méchéria (Z. Bleuse), and another 2 from Suez 
(25th June, J. J. Walker). 
These individuals vary somewhat inter se, but all pertain 
I think to one species, identical with the type (not now 
before me) from Turkestan described and figured in the 
Neuroptera of Fedtschenko’s ‘Turkestan’; the figure 
should serve for identification. The 2 has two short 
cylindrical appendages at the apex of the abdomen after 
the style of Macronemurus, but very much shorter, and 
not sufficiently indicated in the figure on account of the 
position. Eventually a separate genus (allied to Myrme- 
celurus) will probably be formed to receive the species. I 
was inclined to place it in Brachynemurus, an American 
genus founded by Hagen, but the shorter spurs of the Old- 
World insect, or rather the longer first tarsal joint, scarcely 
accord: yet Lrachynemurus is made up of by no means 
congruous materials, such species as b. sackeni having a 
longer first tarsal joint than the others, and ¢ appendages 
that rival those of Macronemurus in length. 
I believe that the range of the same species from 
Algeria to Turkestan has been long proved in entomology.
