splasliiiifi; some wafer oul of a puddle on to the damp mud. Several small "Staphs" 

 at once ran out whic-Ji I recognised as Onypeta lahilis, Er., but there was also a 

 rather smaller species with a more narrowed hind body, and much more active 

 movements (much resembling those of a Myllxna), which proved on examination at 

 home to be Tachyusa concohr, Er. To-day (Oct. 5th) I examined in the same way 

 a lake about two miles distant from the above pond and also partly dried up, and at 

 once found the Tachyvsa, accompanied by Onypeta labilis and great numbers of 

 KeterocerxiH marginatns, F. It is quite possible that T. concolor is not so rare as is 

 supposed, but would often be found to flourish under special conditions. At the 

 small pond it was very ready to take wing, and so presumably to distribute itself 

 generally, although the day was quite dull ; in fact it was this habit which suggested 

 to me the examination of the lake which I have so often worked before. — Id. 



Aculeate Hymenoptera at St. Fillans and the Braes of Balquhidder, Perth- 

 shire. — In the January number of the Ent. Mo. Mag., 1906, I have recorded a list 

 of species found between June 9th and July 5th, 1906. This year I visited the 

 same charming spot a month later, July 5th to August 3rd. The weather was not 

 so fine as in the previous year, but still fair for Scotland ; and although I was con- 

 stantly on the look out I was only able to add seven species to my list, i.e., Crabro 

 cribrariusy Linn., scarce, C. variits, Lep., common, Sphecodes hyalinatus, Schenck, 

 one specimen, Halictus smeathmanellu.'i, Kirb., two specimens, Nomada ruficornis, 

 one specimen, Psitkyrus vestalis, Fourc, common, Chrysis ignita, var. distinctus 

 two specimens. The following species were found again : — Formica rufa, Linn., 

 common, F. fusca, Linn,, common, Lasius flavus, De Geer, common, Myrmioa 

 rubra, Linn., common, Crabro dimidiatus, Fab., Vespa norvegica, Fab., V. vulgaris^ 

 Linn., rare, Andrena albicans, Kirb., common, A. coitana, Kirb., A. fucata, 

 one specimen, Nomada fiavoguttata, Kirb., three specimens, Bombus terrestris, 

 Linn., common, B. pratorum, Linn., scarce, B. hortorum, Linn,, B. agrorum, Fab., 

 common. Diptera were again found in great force, Bombus terrestris, B. pratorum^ 

 Vespa norvegica, and several other species having understudies in close attendance, 

 and often in some numbers, Mr. Edward Saunders- has again very kindly named 

 my captures. — G-. A. James Rothney, Pembury, Tudor Road, Upper Norwood : 

 October 2nd, 1906. 



A correction. — In my report of Gastrophilus nasalis, L., in the last number of 

 this Magazine, page 233, the name of the finder should be Mr. B. Piffard, and not 

 " Mr. J. Piffard," as printed.— F. C. Adams, 50, Ashley Gardens, S.W. : October, 

 1906. 



Empis hyalipennis, Fin., in Dumbartonshire. — On August 25th I took 4 ? ? 

 of a species of Empis in Murroch Glen, near Bonhill, which upon examination 

 proved to belong to E. hyalipennis. Fin., a species not hitherto recorded from 

 Britain, One of the specimens was submitted to Mr, Verrall, who kindly con- 

 firmed the identification.— J. R. Malloch, Bonhill, Dumbartonshire : October, 

 1906.
