Neuroptera collected in Algeria by the Rev. A. E. Eaton, 167 
Sixteen examples at oil lamps in the town, those taken 
in April and May are less strongly irrorated. This pretty 
little spotted-winged species was originally described from 
Asia Minor ; it occurs also in Persia. 
Chrysopa formosa, Brauer. 
Hab, Azazga, 13th September, 1893, at a lamp in the 
inn; Constantine, 20th May, 1895: one rather small ex- 
ample from each locality. 
Chrysopa prasina, Burm. (aspersa, Wesm.). 
Hab. Constantine, 8th May, 1895 ; Le Tarf, 19th June, 
1896. 
One example from each locality, that from Constantine 
has the dark spots on head and thorax nearly obsolete. 
Chrysopa lineolata, McLach. (clathrata, Ed. Pict. nec 
Schnd.). 
Hab. Biskra, 15th April, 1895, one example at light, in 
which the neuration is very slightly varied with black, but 
of the identity of which there can hardly be any doubt. 
Chrysopa flavifrons, Brauer. 
Hab, Hassein Dey near Algiers, 12th April, 1893; 
Biskra, 3rd June, 1893, at light ; Azazga, 11th September, 
1894, at light ; Constantine, 18th May, 1895; Le Tarf, 19th 
June, 1896. 
An excessively variable series, but all apparently 
belonging here so far as one can judge from single 
examples from each locality. 
Chrysopa mutata, sp. n. ? (vulgaris var. 2) 
In size and general characters similar to somewhat small examples 
of C. vulgaris. Differs in most of the nervules being blackish, 
except in the middle, those in the postcostal basal area, and the 
gradate series, entirely blackish (very visible in certain lights) ; the 
ciliations on the margins and neuration apparently shorter (even 
than in Algerian examples of vulgaris) ; only three nervules in the 
inner gradate series in the anterior wings (ordinarily five in vulgaris). 
Hab. Biskra, five examples in March, April and June. 
It is the coincidence of the partially blackish neuration 
and the neural character mentioned above that induces 
me to think these examples have probably so far differen-
