itself, and is apt to be overrun and destroyed by its stronger neighbours, such as 

 water-celery, or even stinging-nettles. One locality in this neighbourhood has 

 been quite destroyed in this way : and in another the cress, for want of care in 

 weeding, is likely to be exterminated. P. sisymbrii, which usually accompanies its 

 congener here, did not occur to me in Cornwall. 



Qymnetron beccabungce. — The typical form of this insect, with the elytra red 

 (except the sutural region), also appears, but sparingly, near New Quay. The few 

 specimens I could obtain are considerably smaller than the black examples met 

 with in the East of England. They were swept off warm banks in meadows. 

 Barypithes sulcifrons also occurred sparingly from nettles in the same locality. 



Tropiphorus carinatus. — I succeeded, in April last, in finding as many as six 

 examples of this scarce species within a few feet of each other. They were in 

 excellent condition, having been bred in thick moss round the roots of the common 

 gorse, in company with Barynotus, Alophus, Cneorhinus, Ccenopsis Waltoni, and 

 other common species. The rare Pachyrhinus denticollis occurs also in similar 

 situations. 



Ceuthorhynchus suturellus (?). — There can be no reasonable doubt that Carda- 

 mine pratensis is the food-plant of this species; as I have taken several examples 

 during May last, all from that plant. The beetle appears to be generally but 

 sparingly distributed in this neighbourhood, and is likely to have been taken in 

 other parts of the country. It should be sought for while the Cardamine is in 

 blossom, as the plant is apt to be choked and disappear amidst the after-growth of 

 the surrounding herbage, and the insect is then very difficult to procure. — W. 

 Tylden, Stanford, Hythe, Kent, June 7th, 1869. 



Food-plant of Ceuthorhynclms viduatus. — It may not be uninteresting to British 

 Coleopterists to know where to look for Ceuthorhynchus viduatus. I was aware 

 that it had been found in sandy places, and once on a wall top ; but did not, until 

 August last, know what plant it frequented. While the Cruciferce furnish pabulum 

 to many species of the genus, I found that, in Berwickshire at least, the insect in 

 question is attached to a member of the Labiatw, viz., Stachys arvensis, or " Corn 

 Woundwort." 



Not having access to "The Entomologist" of 1841, or "The Zoologist" of 

 1844-5, in which the species is recorded as British, I do not know whether its 

 English food-plant has been noted. 



In a neighbouring bog I found at the same time one or two worn specimens of 

 Hydrochus brevis, along with Hygronoma dimidiata, which latter has not, I think, 

 been yet recorded as Scotch. — R. Hislop, Blair Bank, Falkirk, 14th May, 1869. 



Note on Saperda scalaris. — I have just bred two specimens of Saperda scalaris 

 from pupa? found beneath the bark of Alder (Alnus glutinosa). — J. Chappell, 

 Boundary Lane, Greenheys, Manchester, 27th May, 1869. 



Chrysopa vulgaris hybernating in a hornet's nest. — Last autumn Mr. Evans of 

 Lesness Heath, Kent, obtained a very fine hornet's nest, out of which, this spring, 

 emerged a number of living specimens of Chrysopa vulgaris, which had evidently 

 chosen it as a comfortable hybernaculum. This nest was exhibited at a recent 

 soiree of the West Kent Natural History Society, and some of its admirers, 

 in the innocence of their hearts, imagined the .Chrysopai to be the architects ! — 

 R. McLachlan, Lewisham, 4<th June, 1869.
