2116 Insects. 



Chcetocnema aridella and dentipes. Both very common. 



Chcetocnema Sahlbergii. I swept two specimens into my net on the edge of New- 

 church Marsh, and obtained one from moss last year. 



Chcetocnema aridula. One specimen, from the same locality, out of moss. It 

 much resembles aridella, but the thorax is more finely punctured, and presents a very 

 glassy appearance. 



Sphceroderma testacea and Cardui. Abundant enough in the summer. 



Apteropoda graminis. From moss, and by sweeping in the copses at St. Lawrence, 

 &c, but not abundant. Some specimens are brownish copper, others a brilliant 

 green. 



Mniophila muscorum. I add this species, which is plentiful in moss from Shank- 

 lin Copse. Its attempts at jumpiDg are anything but brilliant. 



To the above species, which I have been enabled to enumerate as actually occur- 

 ring, there are, no doubt, others which might be added, later in the season ; as, for 

 instance Thyamis Verbasci, in districts where the mullein grows (for that is decidedly 

 an autumnal species) ; and, on the whole, I consider the island would well repay in- 

 vestigation in this group.

Note on Lyctus canaliculars, Fabr. — The British Admiralty having ordered the 

 use of the Acacia tree for building the most exposed parts of ships, it is interesting to 

 know that even this hard and bitter wood is not free from the attacks of timber-boring 

 insects. A solid, cubical and sound piece, above a foot square, which I had in my 

 possession, was, in the space of a few months, entirely bored through in every direc- 

 tion by hundreds of the larva of Lyctus canaliculars, Fabr., and reduced to a 

 crumbling state. The borings were tortuous and more numerous towards the exterior 

 part and in the liber, the central part of the block being left uninjured or nearly so. 

 The perfect insect made its appearance on May 12th, and continued to come forth un- 

 til the end of that month. — Julian Deby. 



Occurrence of the Locust near Doncaster. — A locust was brought to me on the 5lh 

 of last September, by a man who had found it in a field at some distance from the 

 town. He had it in a box, with some leaves of coarse grass, which it was greedily 

 devouring. When I killed it — which I did by inserting a quill dipped in oxalic acid 

 into the thorax — it emitted a cry somewhat similar to that of the house cricket, but 

 exceedingly faint, and seemed very tenacious of life. — John Hawley. 



Occurrence of the Locust at Bembridge. — In August, 1846, after nearly an hour's 

 chase, I captured a fine specimen of the locust, in a stubble-field close to the sea, at 

 Bembridge, Isle of Wight. I was informed that several specimens had been taken in 

 that locality. — Henry G. Barns ; 5, George Street, Whitechapel, April 8, 1 848.
