wings, terminal area beyond the whitish postmedial line tinged with 
chocolate towards apex: hind wings whitish clouded with brown on 
the margins; discoidal mark dark brown; transverse line beyond 
brownish, wavy, indistinct towards dorsum. 
Expanse, 48 millim. 
A male specimen from Tobetsu, Province Toshima, Hokkaido, 
July 10th, 1902. 
Lord Rothschild has kindly pointed out that this specimen is 
not N. dembowskit, Oberth., with which it had been confused in 
the paper referred to above (l.c., p. 291). 
NOTES ON PSOCOPTERA. 
By J. W. H. Harrison, B.Sc. 
I was interested to read Dr. Chapman’s account of his 
experiences with Ectopsocus briggst, Mclach. (antea, p. 62), for 
they almost coincide with mine in N. Yorks. I began to beat 
the insect during the last fortnight in October from spruce fir, 
and I found that every specimen I took possessed no markings 
at the ends of the veins. This was certainly not due to imma- 
turity, for when I discovered that the species was a veritable 
Ectopsocus I took about a score, and kept them in tubes on 
leaves to allow them to mature if possible. No change occurred, 
and I announced to my friend Mr. R. 8. Bagnall that I had 
taken a new species of Hctopsocus, and, further, I labelled my 
spirited specimens Ectopsocus borealis, and thus they remain. 
In November I obtained the insect in myriads from laurel, yew, 
maple, and sifted it, whilst hunting for spiders, from dead leaves. 
In no case did the specimens agree with McLachlan’s description 
of E. briggsi, but, in the absence of typical specimens of the latter, 
I refrained from noting the matter. I still think that, if not a 
genuine species, it is a northern form. 
As with Dr. Chapman, I beat the insect with crowds of 
Graphopsocus cruciatus, L., but there was almost an equal 
abundance of Stenopsocus immaculatus, Steph. Mr. Bagnall also 
took the same species with Hctopsocus briggst at Grange, Lanca- 
shire, during November. 
On the seabeach at the same place under stones an apterous 
Psocid was captured by Mr. Bagnall. This I have determined 
as a new species, and shall describe it shortly under the name 
Hyperetes britannicus. It differs markedly both in the perfect 
stage and in the nymph from Hyperetes guestfalicus, Kolbe, the 
nymph possessing quite recognisable pointed wing rudiments in 
addition to being marked quite differently. Needless to say, 
Hyperetes guestfalicus seems abundant in the north.
