Swarm of Syrphus Pyrastri on the Coast near Bridport, Dorset—On the 16th of 
August, as I went to bathe at my usual spot, about one mile west of Bridport Harbour, 
T was startled at the number of bees buzzing around me, and, on closer attention, 
I observed that the insect was a trifle longer than our common bee, with a deep black 
body, and several (I think six) transverse bars on the back. As far as my experience 
went, it was stingless. On swimming out about a hundred yards I noticed the same 
bees floating on all sides. The same day my son, who was bathing at one mile to the 
east of me, observed a similar phenomenon. I aim informed that a boat two miles off 
at sea was surrounded in like manner. There was a gentle breeze shifting from north 
to south, and a long drought had preceded the first day of their appearance. On the 
Sunday followiug (the 21st) my friend Mr. Sholl called my attention to several speci- 
mens of the same insect in my garden, at a mile and a half from Bridport Harbour. 
I regret having failed to secure speeimens. I concltide this species to be migratory, 
as I have very rarely seen any of the common flies and butterflies of the coast driven 
out to sea.— George Symes ; Bridport, August 26. 1864, [Communicated by Mr. F. 
Smith, who appends the following note.] 
Note on the ““ Migratory Bees” ? in Dorsetshive—The migratory bee was no doubt 
Syrphus Pyrastri. I saw them in thousands at Bournemouth; one day a line of dead 
ones extending from Pool Harbour to Christchurch Bay, a distance of uot less than 
six miles: their nyubers were really incredible.—Frederick Smith ; British Museum. 
Notes on the Distribution of Insects in the Channel Islands. 
By F. Waxker, Esq., F.L.S. 
THESE notes were made between the 26th of May and the 17th of 
July, 1860; and these seven weeks were thus divided between the 
Islands. and the French coast by St. Malo:—Guernsey, May 26th— 
June 3rd; June 15th—19th. Sark, June 4th—11th. Herm, June 13th 
—14th. Jethou, June 14th. Jersey, June 20th—July 6th. St. Malo, 
June 27th—29th. Alderney, July 7th—9th. 
The weather, till the beginning of July, was generally cold and 
windy, and the previous months were remarkable. on account of the 
low temperature and the quantity of rain, and the backward vege- 
tation.
