HEMIPTERA.

Read 26 th March, 1889 . 
By the additions here made to the list of Norfolk Elemiptera, the 
number of species known to occur in this county is brought up to 
five hundred and five, after allowing for the two errors in the list 
of 1884 {ante p. 700) noticed below, and one species since sunk as 
a synonym. This number is about equal to sixty-nine per cent, of 
the entire British list — a highly satisfactory proportion, and one 
which is scarcely likely to be exceeded by any area of similar extent. 
Our marshes, both on the coast and inland, but more particularly 
the former, produce many interesting and little-known species of 
Cicadina. The business of naming the Cicadina has, it is hoped, 
been in some measure facilitated by my “ Synopsis of our British 
Species,” published in the ‘ Transactions of the Entomological 
Society of London.’ To the four species noted at jj. 701 ante as 
apparently confined, so far as Britain is concerned, solely to this 
county, I have to add nine others ; viz. — 
Stalia boops. Schitldte. This species, which might be passed 
over as a brachypterous form of Nahu Jiacomaiyinatns, occurs 
sparingly on Mousehold Heath. 
Liburnia reyi. Eieb. This fine species I found in August, 
1887, by searching amongst Rushes in a coast-marsh at Weybourne; 
its continental distribution is given as “France, (Jermany, and 
Italy.” 
Idiocerus viduatus. Edw. My brother took a single female 
example of this species off Sallow in Foxley Wood, on the 10 th 
September, 1885. It is allied to, but, according to description 
quite distinct from Id. fasciatw, Eieb,
