488 FAUNA AND FLORA OF NORFOLK : COLEOFTERA. 
Erirhinus acridulus, Linn. Common. 
„ festuoe, Hbst. Marshy places; particularly common 
at Horning. In my long series, I have some 
specimens which agree with the description of 
E. nereis , but the two forms seem to me to run 
the one into the other. 
„ nereis, Payk. Horning (Fowler). 
„ vorax, Fab. On Poplars ; very local, but abundant 
when found. 
„ costirostris, Gyll. Stoke Holy Cross, on a young 
Aspen, in spring and early summer, I see no 
reason to follow Fowler and regard this as a 
variety of maculatus, as, apart from the differences 
in the insects themselves, their food-plants and 
times of appearance are different. 
„ maculatus, Marsh. On Sallows and Willows, generally 
distributed and common. 
,, t.eniatus, Fab. On Scilix alba, at Thorpe, September, 
1876. 
,, salicinus, Gyll. On Willows, rare; Horning, May, 
1889 ; previously recorded from thence by Curtis; 
Hoveton (Power). 
,, pectoralis, Panz. On Sallows ; widely distributed, 
but not common. 
,, tortrix, Linn. On Poplars, near Lakenham bridge ; 
locally common. 
Mecinus pyraster, Hbst. Common. 
Hydronomus alismatis, Marsh. On water-plants ; common. 
Bagous binodulus, Ilbst. “ Marshes near Norwich ” (Stephens). 
„ tempestivus, Hbst. Local, but rather common where it 
occurs. 
„ petro, Hbst. Brandon, one in May, 1S88, one in 
May, 1889 ; St. Faith’s Common, July, 1889. 
,, lutosus, Gyll. Very rare; Wretham Heath, one example,
