24 Comparison of the Floras of 



ley Hill, near Manchester, in descending from Garn, a moun- 

 tain situated between Nant Francon and the Pass of Llanberis, 

 to Cwm Idwal, discovered under a detached piece of rock, 

 many hundred feet below its summit, a fine living specimen 

 of Chrysomela cerealis ; and the abdomen of a smaller indivi- 

 dual, which, unluckily, had been destroyed. From the dis- 

 parity in point of size, it is very probable that the sex of these 

 specimens is different; but it would be hasty to pronounce 

 them male and female, unless they were proved to be so by 

 dissection, which would render them unsuitable for the cabi- 

 net. I saw both specimens, which still remain in Mr. Glover's 

 possession, soon after they were procured : the perfect one was 

 then alive, and was certainly a very splendid insect. Stimu- 

 lated by his success, Mr. Glover continued his search with 

 redoubled ardour, but was not so fortunate as to meet with 

 another individual. 



I may observe, that, among the mountains constituting the 

 district termed Snodonia, vast numbers of beetles are destroyed 

 by foxes, which prey upon them freely, as is evident from the 

 elytra and other indigestible parts contained in their faeces. 



A good living specimen of Chrysomela cerealis was obtained 

 in the same locality, in the summer of 1829. It is now in the 

 cabinet of that excellent practical naturalist the late Mr. Ed- 

 ward Hobson of Manchester.

Art. X. A Sketch of the Flora of Richmond, Yorkshire, as com- 

 pared with that of Thirsk, in the. same County, By T. E. L. 



Sir, 

 The town of Richmond is situated at the lower extremity 

 of a deep valley, through which the rapid river Swale mean- 

 ders, here about thirty miles from its source. The general 

 aspect of the neighbouring country is much varied, and justly 

 famed for the bold and romantic scenery it presents. Along 

 the banks of the river the country is well wooded, though the 

 trees seldom arrive at any great size. Those which most 

 commonly prevail are, the ash, the elm, the mountain ash, 

 and the oak ; while the underwood is generally the hazel, 

 mixed with several species of Ribes, Viburnum O'pulus, 

 Z)aphne Laureola, &c. The hornbeam is not found in this 

 neighbourhood. As we advance from the river, and ascend 

 to the high grounds, the land is of a poorer quality, and the 

 woods, if any, are principally fir.
