Donacia impressa, Payk. Not common; Ranworth; Lakenham,

„ vulgaris, Tsch. Rare ; a single specimen off Reed in 
a pit at Arminghall in April, 1890; Cringleford,

„ clavipes, lab. ) 
„ oinbrea, TIbst. Rare ; Ranworth. 
„ sericea, Linn. Common. 
„ discolor, Panz. Whitwell Common, rare ; very likely 
to be passed over as D. sericea , from which it may 
be known by its rather smaller size, stouter legs, 
and much more rugoscly punctured thorax. 
,, rraccata, Scop. Locally common on Reeds; Horning; 
Ranworth ; Surlingham (Thouless). 
„ affinis, Kunze. Ranworth (Thouless). 
ILf.monia curtisi, Lac. Taken rather plentifully near Fakenham 
on Potamogeton pectinatus by the Rev. T. 
Skrimshire (Stephens). “On the banks of the 
Yaro between Thorpe and Norwich, the 14th June, 
1811; the Rev. T. Skrimshire met with it near 
Burnham, and afterwards near Wells in Norfolk 
the 29th of May in salt-water ditches.” Curtis’ 
statement as to the locality of Skrimshire’s 
captures is, I think, to be preferred, as the known 
habitat of the species is on water-plants in 
brackish ditches ; and if an Haemonia did occur 
on the banks of the Yare between Thorpe and 
Norwich the probability is that it was II. appendi- 
culafa, a larger insect than II. curtisi, with 
distinctly clavate femora, which occurs very rarely 
on plants growing in fresh water. 
ZEUGomoRA subspinosa, Fab. On Aspens in woods, common. 
“ In Betula alba ” according to Burrell.
