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 Bigsbyana) : 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 Quadripunctata ?) ; two black-winged 

 Tenthredinetce ; and a red-bodied Ichneumon, with a yellow 

 scutellum ( I. Devinctor ?J. I took a silver Chrysomela of 

 the same species, from the very same spot yesterday ; a sin- 

 gular coincidence. I have also captured several moths : four 

 Geometrce, and a Tortrix, none of which have much preten- 

 sion to beauty. I have a very elegant little species of locust, 

 the Spotted Fan- wing (Aery- 

 dium Ornatum): the thorax 

 is elongated and tapers to a 

 point, which reaches to the 

 tail ; the wings are perfectly

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), 

 a large beetle, the elytra black, marked with rows of round
