NOTES ON THE BRITISH SPECIES OF SYM- 
PHEROBIUS (HEMEROBIUS), INCLUDING ONE 
HITHERTO UNNOTICED. 
By Kenneto J. Morton, F.E.S. 
(PuaTE V.) 
In the Trans. Am. Ent. Soc. xxxu., December, 1905, pp. 28-29, 
Banks split up the genus Hemerobius into three, giving the 
following synopsis :— 
No outer cross-veinlets in hind wings, only four, or 
less, in outer gradate series of fore wings; usually 
but two radial sectors; a cross-veinlet connecting 
first radial sector to median; the median is usually 
a little bent toward the cubitus at connecting vein- 
let; in hind wings the median usually forks plainly 
beyond forking of radial sector: small species . Sympherobius. 
Outer cross-veinlets present in hind wings; more than 
four veinlets in outer gradate series in fore wings; 
usually three or four radial sectors. 
(a) A cross-veinlet connecting first radial sector 
to median some distance out on the former; 
often four radial sectors ; the median is rarely 
bent toward the cubitus at connecting veinlet ; 
in hind wings the first radial sector forks as 
far out as forking of median: larger species. Borionvyia. 
(b) The cross-veinlet from median to radius is 
before or at origin of radial sector, never out 
upon it; three, rarely four, radial sectors; the 
median is more or less bent toward cubitus at 
connecting veinlet; in hind wings the median 
is forked further out than fork of first radial 
sector .. ; Hemerobius. 
The author states ‘the this teaion will apply to the 
Kuropean species thus :—Hemerobius (s. str.): humuli, micans, 
atrifrons, nitidulus, stigma, limbatellus, lutescens, orotypus. Borio- 
mytia: concinnus, 4-fasciatus, subnebulosus, nervosus. Symphero- 
bius: elegans, parvulus, inconspicuus.
