From Musselburgh the following species may be recorded : Oreogeton flaoipes,*

 24.VIT.0(>, Dolichopus pennatux* Mg., S 9 , 30.VII.06, and on the same day D. 

 longicornis* Stan., J 9 > in some numbers, also Xanlhochlorus ornatns* Hal., 2 J (? , 

 Azelia zetterstedli* Rnd., was common on UmheUiferx, 24..VII.0f>, and several 

 examples of Scatnphaga maculipes,* Ztt , and Calobata cibaria* L., were taken, 

 5.VII.H6. On my window T got Lasioxoma Jiirtum* Mg., 2 <? <J , I 9 , 1. VIII.06, 

 Bolilophila cinerea, Mg., 9 j 28.X.06 ; and I may also mention CuJex pipiens,\i., 

 2 9 9. ly.XII.OG, surely a late date. A fine specimen of Syrphns guttatus, Fin., 

 S , occurred, 24. VI. 06, and Porphyrops riparia, Mg., was common along the river 

 banks ; it was also common at Polton. 



I re-visited Aberfoyle on August 20tli, and remained till September 3rd. The 

 weather was good, but flies were not quite up to the average as regards numbers, 

 though my list of species is longer than on any previous visit. During the first 

 week of our stay Bibio pomonse, F., was in swarms. For miles over the hills they 

 were to be seen in crowds flying over the bracken and heather, or clinging to the 

 rocks, while every pool had its quota of dead or drowning individuals. During the 

 previous summer a good sized plantation, chiefly oak, had been cut down, and on 

 stumps remaining I found many flies, such as : Micropalpus vitlpinus, Fln.,commo:', 

 Trixa oestroidea, Desv., (J, and Pallopfera nsta* Mg., 2 9 9 , 28. VIII.06. Sun- 

 ning on leaves I got Chilosia longula,* Ztt., $ , 25. VIII. 06, Syrphus cinctellus, 

 Ztt., several, S. ductus* Fin., 4 9 9 , 23.VIII.06, Xylota forum, ¥., J, 1.IX.06, 

 Pyropkwna rosarum, F., S, Conops Jiavlpes,* L., <? , 23. VIII. 06, and Loxocera 

 albiseia* SehrV., <? , I.IX.06. Pipunculns was in some numbers, and on August 

 23rd I took in a very short time 18 <? (? and 1 9 of campe.ifris, Ltr., and a beauti- 

 ful (? of xanlhopus,* Thoms. On the same day occurred also Arctophila mussitans, 

 F., $, Ischyrotyrphus glaucius, L., 5 9?. Hylemyia flavipennis, Fin., 9. and 

 Morellia simplex,* Lw., both sexes. On August 25th I took two fine 9 ? of 

 Pachyrrhina imperialis, Mg., and on the 28th, while near the top of Craigmore 

 three Tabanids settled on my coat, but I caught only one, which proved to be a 

 rather worn example of Tabanus sudeticus, Zlr., 9 . A number of Hydrophorus 

 borealis,* Lw , were found at a small pool on August 27th, but as they uever left 

 the surface of the water they were difficult to catch, the net being soaked at each 

 attempt. However, I managed to get about twenty specimens, including both 

 sexes. Other DoUchopodidx taken included Argyra leucocepJtala,* 'Mg., 2 ^ S, 

 24. VIII. 06, Gymnopternus terosus,* Fin., a common species, Hypophyllus obscur- 

 ellus* Fin., ^ , 23. VIII.06. Dolichopus signatus,* Mg., 1 <? , 2 9?, 23.VIII.06, 

 D. vitripennis,* Mg., <? 9, 2.IX.06, and D. di.soifer,* Stan., 9, 24.VIII.Ci6. On 

 previous visits I have taken this species, earlier in the season, in some plenty. 

 General sweeping produced Elgiva lineala,* Fin., c? , 29. VIII. 06, Allophyla atri-
