Note on a new British Ichneumon. — The following species was detected by me 

 last autumn, in a marsh near the sea at Gellyswick, in this county. Specimens 

 were forwarded to Mr. Desvignes, who referred them to M. Wesmael, by whom 

 they were pronounced to be new to science. Under these circumstances, I 

 requested Mr. Desvignes to draw up a description of the species. He has kindly 

 compUed, and I now forward it for publication. The insect belongs, according to 

 M. Wesmael, to his sub-division Ichneiimones Pneustici, so named on account of the 

 circular spiracles. It belongs to Section IX of Gravenhorst's genus Ichneumon.

Lebia crux-minor in Scotland. — When out collecting Coleoptera on September 

 24th, I had the good fortune to take, among other things, a single specimen of 

 Lebia cr^lx-minor in fine condition. The specimen is a female : I found it in the 

 immediate neighbourhood of Dumfries, and, so far as I know, this is the second 

 example of its occurrence in Scotland. — W. Lennon, Crichton Eoyal Institution, 

 Dumfries. 



Swarms of Brosophila fenestrarum in London. — Several houses in Holborn have 

 been of late infested with small flies, of which I send you specimens. To such an 

 extent have they increased during the last week that the windows are positively 

 darkened by them. I should much like to hear if this visit is likely to have been 

 caused by any local influence, and if it is in any way exceptional. — H. Newman, 5, 

 Oval Eoad, Kennington, S., September 21st, 1867. 



*^* The flies sent by my con-espondent have been submitted to a friend versed 

 in these matters, and he informs mo that they are Drosophila fenestrarum-, a generally 

 common species, the larva of which feeds on vegetable debris, such as sawdust, &c. 

 Their great abundance in Holborn is doubtless owing to the presence of some 

 condition favourable to their development. — R. McL.
