1518 Insects. 



longer than either the fourth or sixth, which are nearly of equal length. (Zool. 1239). 

 As I have not been able to find that the insect has been previously noticed or de- 

 scribed, I have assumed it to be a new species, and have named it " dispar." — G. T. 

 Rudd ; Worsall Grange, Yarm, October 7 th, 1846. 



Discrepancy between the two antennce of a Dytiscus. — A short time since, I took a 

 male specimen of Dytiscus punctulatus in a pond on Wimbledon Common, with one 

 antenna considerably shorter than the other, so much so, that I thought at first it was 

 damaged ; the number of articulations are however complete in both, and as far as the 

 fifth joint of equal size, but from that joint they diminish rapidly in the left antenna, 

 the four terminal joints of which are only equal to the two last of the other : the total 

 length may be about two-thirds. In the Crustacea, such differences are frequent, 

 and accounted for, on the supposition of their limbs having been lost and reproduced, 

 but as no true insect has been hitherto discovered to possess this power of issuing se- 

 cond editions of lost arms and legs, what can be the cause of a similar one-sided varia- 

 tion in them ? — George Guy on ; Richmond, Surrey, September Wth, 1846. 



Occurrence of the Locust near Knaresborough. — Last Wednesday, a person brought 

 me a specimen of the locust, which had been taken in a barley-field, about eight miles 

 fro.ni this place. — James C. Garth ; Knaresborough, August 28th, 1846. 



Capture of the Locust on Peckham Rye. — I yesterday caught a very perfect male 

 specimen of the migratory locust on Peckham Eye ; it took very short flights of only a 

 few yards at a time, and was easily overtaken. — Bevington Newman; 2, Hanover Street, 

 Peckham, September 1st, 1846. 



Occurrence of the Locust in Hyde Park. — Yesterday a person brought to the Mu- 

 seum a specimen of Locusta migratoria, which he had taken the day before in Hyde 

 Park. — Adam White : British Museum, September 2nd, 1846. 



Occurrence of the Locust at Kingsbury, Middlesex. — While shooting on the 2nd at 

 Kingsbury, I observed something moving about a meadow in a curious manner, and on 

 going up to the spot, I sawjwhat I at first took for a large Sphinx, but on catching it, it 

 proved to be a fine specimen of Locusta Christii (Curtis) ; on reaching home with my 

 prize, I was very much surprised to find that another had been left for me, that was 

 taken near Stanmore Marsh, in a pea-field, two or three days ago. — F. Bond ; Kings- 

 bury, Middlesex, September 3rd, 1846. 



Note on the occurrence of the Locust in Yorkshire and Devonshire. — Several speci- 

 mens of this interesting insect, captured during the recent hot weather on the coast of 

 Yorkshire, have lately come beneath my notice. Happening to be at Bridlington in 

 August, I had the opportunity of obtaining a fine specimen, which was taken on Flam- 

 borough Head, at the beginning of the month. Mr. Strickland also tells me that two 

 have been brought to him since I left, captured at Bridlington, he thinks, on or about 

 the 28th. I am informed by Professor Balfour, of Glasgow, that, during a recent ex- 

 cursion in the west, he saw a specimen which was taken a few weeks ago at Dawlish, 

 on the coast of Devonshire. Considering the many other instances in which I hear it 

 has occurred, I was at first inclined to attribute the appearance of this insect to the un- 

 usual hotness of the season. This, however, can scarcely be the case, for at the late 

 meeting of the British Association at Southampton, Mr. Strickland informed me that 

 more specimens occurred on the coast of Yorkshire last year than this, which, it will be 

 remembered, was a particularly cold and wet season. One of these he has still in his 

 possession, but the rest have been distributed amongst his friends. I have not heard
