specimens to make sure. Year after year I searched in vain, though 

 I was in the same garden almost every day, but when strolling in the 

 garden early in the evening of May 24th, 1873, I noticed a peculiar 

 shimmer in the air under a large mulberry tree ; upon examination it 

 proved to be caused by hundreds of this species. I have never seen 

 it since. 



It is very closely allied to S. recurva, but is longer and thinner, the thorax 

 somewhat shining, very distinct from the dull thorax of S. recurva ; the wings are 

 broader, with the forks of the forked vein widely diverging at the tip. 



10. S. minutissima, n, sp. 



Nigricans, opaca ; abdomen depressum ; pedes fubci, geniculis saltern tarsisque 

 sordide albidis, tibiis posterioribus sub-clavatis ; halteres et palpi sordide albidi ; 

 alffi latffi. I^o^g-' 1 ^^1^- 



This species occurred in profusion at Pagham Harbour (then 

 being reclaimed from the sea) on June 22nd, 1876 ; it was so small 

 that it readily crept through the meshes of my fine muslin net, but, 

 like all the species of the genus, was most reluctant to fly. 

 1 Last winter I made some experiments in Micro-Photography, and was most 

 successful with the wings of this species ; I have, therefore, given a woodcut of the 

 ^^.^.^^H^^ wing, which was taken from a photograph. It is

Uthed with pale short dense pubescence, which is also on the scutellum ; the an-

 with a whitish sheen over them ; abdomen depressed, about two and a half tmies 

 longer than broad, widest a little after middle ; legs obscure brownish, knees tars:, 

 halteres and short palpi dirty dull whitish, in paler specimens the legs are dull pale 

 brownish ; all the tibi^, especially the posterior, widened towards the tip. 



11. Fsychoda alhipennis, Ztt. : not at all uncommon on windows 

 in my house. 



12 P. hmeralis, Mg. : also not imcommon on windows here, and 

 I possess a considerable number of either this or a pos»,b^ new 

 Bpecies, larger and more ochreous, bred from decaying snails by Mr. 

 J H. A, Jenner of Lewes. Stephens included P. ku,ne.-ahs m h.s 

 Systematic Catalogue of British Insects. 



13. I>icrano,n!,ia ornata, Mg. : many specimens of this handsonie 

 species were correctly named and distributed by the late Mr_ J. a 

 Dale, but yet I do not find it recorded as Bnfsh. I caught one 

 myself this year at Bonchurch, I. AV., m June.
