Trjphonid, a group usually confined in their attacks to the Tenthredinidx. (8) One 

 S of the Microgastrid Braconid, Agethis brevisetis, Nees, none of which genus has 

 preTiously been noted as preying upon Psychids. Subsequently, during the follow- 

 ing spring, 20 more specimens of Spiiwlia maculipennls, of which but five were ? ? , 

 emerged from the same batch of hosts. — Claude Morlet, Monks Soham House,

Ornithomyia lagopodis, Sharp, from a, Tawny Owl in Fifeshire. — When 

 recently comparing an Ornithomyia from a Tawny Owl {Syrnium aluco) shot near 

 Dunfermline, Fife, in September, 19u6, with some obtained from Red Grouse at Killin, 

 Perthshire, in August of the same j'ear, I was unable to detect any difference be- 

 tween them, all agreeing well with the description of the Grouse-fly, O. lagopodis, 

 Sharp. I have submitted the specimen from the Owl, and one of those from the 

 Grouse, to Dr. Sharp, and he says there can be no doubt both are O. lagopodis. 

 The specimen from the owl may only have been a temporary visitor to that bird ; 

 but, as Dr. Sharp remarks in his letter to me, " it is possible that 0. lagopodis may 

 be a geographical, rather than an ethological form." — William Etans, Morningside 

 Park, Edinburgh : January 2oth, 1909. 



Notes on Diptera in Scotland. — I have a number of records since my last note 

 on Diptera in Scotland (Ent. Mo. Mag., 1907, p. 110), which seem worth publishing, 

 including as they do some species new to Scotland, as well as several others of 

 interest. More names might have been given, but the identification of Diptera is, 

 in some cases, not an easy matter, and doubtful ones must stand over for verification. 



At Comrie, in July, 1907, many species were taken, including additions to the 

 British list. Two of these I have already recorded in this Magazine (1908, p. 128), 

 and a third, Hydrotsea borussica. Stein— of which I got a S — has been brought 

 forward by Mr. Grimshaw in " Annals of Scott. Nat. Hist.," 1907, p. 223. Other 

 species taken were Trichosia splendens, Winn., $ ; Tabanus cordiger, W., 2 ? ? ; 

 Dioctria oelandica, L., $ on leaf in wood ; Trichopeza longicornis,'M.g., 2 (J ^ ; 

 Dolichopus atratus, Mg., common ; D. picipes. Mg., common ; Porphyrops rivalit, 

 liw., (J , this species as British has, I think, only been taken by Col. Yerbury ; Chry- 

 sotus graml.neus. Fin., very abundant on the hedges and vegetation along the sides 

 of a road (I have also taken it in similar places here) ; Orthoneura nobilis. Fin., $ ; 

 Chilosia ncutellata, Fin., $ ; Criorrhina oxyacanthse, Mg., $ : Hydrophoria 

 ambigua. Fin., J ; Pegomyia geniculata, Bche., (= ephippium, Ztt., of List) both 

 sexes ; P. fulgens, Mg., 2, $ $ ; Sapromyza IQ-punctata, Fin., one specimen ; S. 

 lupulina, F., 2 J J ; .S. affinis, Ztt., $ ; and Helomyza lasvifrons, Lw., common. 



Last year, 19C'8, was my first in the Blairgowrie district of Perthshire, and I 

 opened the season on April 6ih hj taking Melangyna quadrimaculata, Verr., <? . 

 I found it afterwards to be common, but only got one $ . In May I took Chryso- 

 gaster virescens, Lw., ^ ; Syrphus vittiger, Ztt., ? (also one in August) ; S. punc- 



mediately an ichneumon fly appeared at the leaf, and followed the silken thread left by the larva 

 as it descended, flying round it down to the gi-ouiid. I do not remember to have read of any one 

 else having a similar experience." Unfortunately both were unidentified. The only at all 

 analagous case of which 1 am aware is Bignell's observation of the Pimplid Acrodaxtyta degtner, 

 Hal., walking down the spider's web in order to oviposit in the hody oi Linyphia obicura, Bl. 

 (given in Ichn. Brit, iii, 133).
