(R.C.B.) ; torvus, O. S. (R.C.B.); annulatus, Zett. ; lineola, Zett., rare (R. C. B.) ; vittiger, Zett., rare (C. J. W.) ; grossulariae, Mg. (R. C. B.) ; ribesii, L., very abundant ; vitripennis, Mg., common ; latifasci- atus, Macq., rare (R. C. B.) ; nitidi- collis, Mg. (R. C. B.) ; nitens, Zett. rare ; corollas, Fab., very abundant; luniger, Mg., very common ; bifasci- atus, Fab., common ; balteatus, De Geer,very common ; cinctellus, Zett.; cinctus,Fall.(R.C. B); auricollis, Mg. = var. maculicornis, Zett., the variety is the chief if not the only form occur- ring with us; punctulatus, Verr., com- mon ; guttatus, Fall., very rare (R. C. B.) ; umbellatarum, F., rare (C. J. W.) ; compositarum, Verr., rare (R. C. B.) ; labiatarum, Verr., rare (R. C. B.) ; lasiophthalmus, Zett., very common in spring on sallow bloom, etc. ; arcticus, Zett., not com- mon ; barbifrons,Fall.,rare(R. C.B.) Sphaerophoria scripta, L. (R. C. B.) ; men- thastri, L., var. picta, Meig. is prob- ably our commonest Sphaerophoria ; var. toeniata, Mg., is however com- mon as well ; menthastri, L., type is rare at least ; flavicauda, Zett. (R. C. B.) Baccha obscuripennis, Mg. (R. C. B.) ; elongata, F. Sphegina clunipes, Fall., not uncommon Ascia podagrica, F., very abundant ; flora- lis, Meig., common Brachyopa bicolor, Fall., very rare, Bir- mingham (R. C. B.) Rhingia campestris, L. Common Volucella bombylans, L., common ; pellu- cens, L. ERISTALIN.*: Eristalis sepulchralis, F., common in Black- root Bog ; tenax, L., abundant as usual ; intricarius, L., common ; arbustorum, L., very abundant ; pertinax, Scop., very abundant ; ne- morum, L., apparently rare ; horti- cola, De Geer, common Myiatropa florea, L., not common Helophilus trivittatus, F.,very rare (R. C. B.); hybridus, Loew., not common, Black- root Bog ; pendulus, L., common gene- rally ; versicolor, F., rather common in Blackroot Bog ; transfugus, L., rare, ERISTALIN.S (continued) a few in Blackroot Bog ; lineatus, F., the occurrence of this species in great numbers is one of the most charac- teristic features of Blackroot Bog. On a fine day I have seen it in thousands, several at every flower of Caltha pa- lustris ; frequently two or three males at a time courting each female in the manner described in Verrall's book Merodon equestris, F. Has established it- self here as elsewhere, and is gradu- ally becoming common MILESIN^E Criorrhina berberina, F., very rare ; oxya- canthas, Mg., very rare ; floccosa, Mg., very rare (R. C. B.) Brachypalpus bimaculatus, Macq., very rare, one only (R. C. B.) at Sutton Xylota segnis, L., common ; sylvarum, L., rare at Sutton (R. C. B.), Idlicote (L. C. Keighley-Peach), not un- common at Hay Woods (C. J. W. ); florum, F., not uncommon in Black- root Bog Syritta pipiens, L., very abundant every- where. The males of this species court the females in a very similar manner to those of Helophilus linea- tus, F., hovering near with head and body inclined towards the female and the wings in a state of rapid vibra- tion so as to be almost invisible, the body meanwhile also being vibrated Eumerus ornatus, Mg., Hay Wood near Kingswood (C. J. W.) Chrysochlamys cuprea, Scop., Hay-wood near Kingswood (C. J. W.), Idlicote (L. C. Keighley Peach) ; the species is usually rare wherever I have col- lected in the midlands Arctophila mussitans,F., very rare (R.C.B.) Sericomyia borealis, Fall, and lappona, L. Both rather common in Blackroot Bog CHRYSOTOXIN.* Chrysotoxum cautum, Harris., Whitchurch (J. H. Bloom) ; arcuatum, L., rather common in Blackroot Bog; festivum, L., rare (R.C.B.) ; bicinctum, L.,not uncommon, Sutton and Hay floods (C. J. W.), Idlicote (L.C. Keighley-Peach) CONOPID^ CONOPIN.*: Conops flavipes, L. Not common 163 Sicus ferrugineus, L. (R. C. B.) Myopa buccata, L., not uncommon at hawthorn blossom, etc. ; testacea, L. (R. C. B.)
