had been cut down in the winter ; the sap has flowed from 
it profusely^ and is still flowing, and the whole top, and all 
down the sides_, is covered with a thick coat of that pink 
mucilage you mentioned the other day. Great numbers of 
insects were crawling about this substance^ several of which 
I took ; a convex Chrysomela^ resembling silver^ sculptured 
with black curves and marks ( Eumolpus Bigshi/ana ) : it is 
a very elegant little beetle : another beetle^ of a bright crim- 
son ( Cucujus Rufus ) ; two or three little black ones^ with 
scarlet bands ( Ips Quadripunciata ? ) ; two black-winged 
TenthredinetcB ; and a red-bodied Ichneumon, with a yellow 
scutellum ( I. Devinctor ? ), I took a silver Chrysomela of 
the same species^ from the very same spot yesterday ; a sin-

the Spotted Fan-wing ( Aery- 
dium Ornatum ) : the thorax 
is elongated and tapers to a 
point, which reaches to the

they reflect the prismatic colours, like mother-of-pearl. On 
a pool by the road-side, I caught two species of Water-mea- 
surer ( Gerris ), very much like my former species^ but both 
of these have wings, whereas the former is apterous in all its 
stages. I caught also a four spotted Ladybird ( Chilocorus 
? ) and a little Cur-culio in flight. 
F, — I have been busily engaged to-day, sowing wheat, and 
have noticed some novelties. I took, crawling on the newly 
ploughed ground, the Copper-spot Carab ( Calosoma Calidum J, 
a large beetle, the elytra black, marked with rows of round
