FAUNA AND FLORA OF NORFOLK : HE.MIPTERA. 843 
Jassaria. 
Paramesus phragmitis, Boll. Roydon Fen, 21st September, 
1908 (Edwards). 
Deltocephalus socialis, Flor. Sandy banks of Ringniere, 
Wretham Heath, 30th August, 1907 (Edwards). 
,, maculiceps, Boh. Rather freely, but females only, 
at Roydon Fen, 21st September, 1908 
(Edwards). 
Thamnotettix attenuatus, Germ. 1 was rather surprised 
to meet with this species at the last-named 
locality, having previously found it on Mouse- 
hold Heath only. 
Typhlocybina. 
Dicraneura similis, Edw. Roydon Fen, 21st September, 
1908 (Edwards). 
Delphacina. 
Stenocranus fuscovittatus, Stal. (olim gen. Liburnia). 
One male, with the species last-named. 
Kelisia pallidula, Boh., (olim gen. Liburnia). With the 
last-named, not uncommon. 
Delphax signoreti, Scott. ( olim gen. Liburnia). One female 
at Brundall. 31st August, 1907 (Edwards). 
Psyllid.e. 
Aphalara pilosa, Oslin. This is the species previously- 
recorded as . 4 . artemisice, Forst. The latter 
insect, which is distinguished from A. pilosa 
by the absence of sub-erect hairs on the elytra, 
and of which I have seen undoubted examples 
from the Isle of Portland, lives on Artemisia 
absinthium and A. campestris. I found the 
latter plant as a roadside weed just outside 
the town of Thetford in August, 1S88 ; but, 
though I was in search of Eupteryx artemisice, 
Kbm., of which it is the food plant, it did not 
produce a single insect of any kind.
