1286 Insects.

may mention the following as most worthy of notice.

To these I may add a pair of a very large and beautiful species

 several specimens of a new Dendrophilus (which I shall hope shortly 

 to describe) ; and a series of a very distinct Aphodius which does not

Happening to be at Caermarthen during one of those heavy floods 

 which are so common in all hilly districts, and nowhere more so than 

 in the large tract of country stretching southwards to the sea below 

 the Welch mountains, I had a good opportunity of witnessing in a 

 short time the comparative distribution of the Coleopterous genera in 

 the rich Vale of Towey, — the first fruits of which were washed up in 

 the course of a few hours and left by tens of thousands — in living my- 

 riads, — amongst the refuse which remained after the waters had par- 

 tially subsided. To describe indeed the vast confusion of life which 

 existed in the rubbish when the flood commenced its retreat would be 

 utterly impossible. It must be seen to be conceived. 1 have had num-
