radiatusj growing on elm in Gribside. RhizophaguK perforatux — an addition to our 

 List (Entom. Record, 1904) was taken from beneath the bark of a felled tree at 

 Lockliaugh, September, 1903, and at the same locality early last year. In October, 

 19 '4, I came across a very small example of what seems to be Ihis species from the 

 above mentioned fungus, P. radiatun. 



Of course this short note is not in any sense a complete account of our local 

 NitlduUda;, but rather of a few things tliat have occurred to me by indiscriminate 

 and hapliazard collecting. — Richaed S. Bagnall, The Groves, Winlaton-on-Tyne :

Diptera in Scotland. — I have taken sijecimens of the following Dipfera during 

 the past two seasons, and though some of them have been recorded in the "Annals 

 of Scottish Natural History" (by Mr. Grimshaw in his "Diptera Scotica"), I 

 venture to send these notes for publication in the " Ent. Mo. Mag.," as records of 

 Diptera from Scotland are but few. I am greatly indebted to Mr. Grimshaw for 

 r. uch kind assistance given in the determination of my captures. 



I collected at Aberfoyle for three weeks in July, 1903, and had one day's 

 collecting there last year on June 30th. Nearly 140 species have been deter- 

 mined, and I have a great many still to work out. In addition to Oxycera dives 

 and Microdon viutabilix, already recorded in this Magazine, several other interes- 

 ting flies occurred. Therioplectes xohtitialis, Mg., was a common species, and I took 

 Tabanus sudeticus, Zlr., g , July 7th, 1903, at rest on bracken. Paragus tibialis, Fin., 

 occurred at » sandy bank at which I also took the bees Halictus tmeathmanellus 

 and H. leucopus, which interested me, as there appears to be some connection 

 between the Paragus and Halicti, at the same and similar banks Metopia leucoce- 

 pkala, Rossi, was in abundance ; and July 6th, 1903, 1 took a ? of Jf. amabilis, Mg. I 

 was glad to take a t? of VerraUia avcta, Fin., June 30th, 1904, my first capture of the 

 species. Both sexes of Pipizellajfavitarsis, Mg., were rather common in moist places, 

 and Chry Kogaiier solstitialis. Fin., Syrphus compositarum, Yerr., S. arcticus, Ztt.,and 

 several fine specimens (both sexes) of Eristalis rupium, F., were taken at wild rose 

 One morning, July 8th, 1903, I found Chrysotoxum arcuatum, L., in fair numbers 

 on bracken in wooded places, strangely the only occasion on which I saw the 

 species ; C. bicinctum also occurred. On July 1st, 1903, 1 took a fine S of Cynomyia 

 alpina, Ztt., this species has now been recorded from several localities in Scotland. 

 Some forty species of Anthomyidx were met with, including Sphecolyma inanit. 

 Fin., 2 (J , July 6th, 1903. Pegomyia transversa, Fin., Eomalomyia aerea, Ztt., 

 and Caricea means, Mg., in coit4. Hyetodesia pallida, F., was abundant on 

 bracken and low shrubs, especially in the wooded shores of Loch Ard. I do not 

 know if my series (a long one) is aU the one species, as the S varies in colour, only 

 about half of those taken being entirely yellow or testaceous as described by Meade, 

 the rest having more or less of the thorax dark grey, and I notice that in most of 

 the dark specimens the eyes are not so closely touching as in the former. All the 

 females taken are entirely light coloured. A small bluish-grey Limnophora, which 

 Mr. Grimshaw thinks is solitaria, Ztt., was common on the Aberfoyle hills resting 

 on lichen-covered rocks, &c. In these situations it afforded a beautiful example of 

 " sympathetic "coloration. I also met with the species at Callander last September,
