OF these unobtrusive insects Verrall wrote in Volume V I I I of his " British Flies " , " the Syrphidae may be the grandest, but the Pipunculidae are the most exquisite hoverers in the Diptera, as they can hover easily in a folded net, between the folds, without touching the network." They are small, thinly-haired and dark, with enormous globular heads mostly composed of their Compound eyes ; their heads are amazingly mobile. The larvae are internal parasites of Bugs (Hemiptera) of the sub-order Homoptera. When fully developed the parasitic larva occupies most of the host's abdomen and faces towards the head. For further details of their life-history consult Perkins, F. H. " Leaf-hoppers and their Natural Enemies"—Hawaiian Sugar Planters' Assocn. Div. Ent. Bulletin, Vol. 1, pt. 4. pp. 123-57, 1905. For a relationship with Froghoppers one can read Jenkinson, F. H. "Verrallia aucta and its h o s t " E . M . M . Vol. 39, pp. 222-3, 1903. The British species can be investigated with the help of Verrall's British Flies, Vol. V I I I and of Lundbeck's Diptera Danica, Vol. VI. There has of late been a movement to reorgan ise the Classification of the old genus Pipunculus, giving some groups the status of genera. Three useful papers have been written by Mr. Collin : 1 " T h e British Species of the sylvaticus group of Pipunculus (Diptera) " Ent. Mon. Vol. 56, pp. 270-6, 1920. 2. " The British Species of the genus Verrallia ( D i p t e r a ) " E . M . M . , Vol. 67, pp 234-6 1931. 3. " T h e British Species of the rufipes group of Pipunculus (Diptera) " E . M . M . , Vol. 73, pp. 209-18, 1937. Theodore Becker in 1897 and 1900 wrote, " Dipterologische Studien 5, Pipunculidae " Berlin ent. Zeitschr. Vols. 42 and 45. Professor Pius Sack has commented on the work of the above Becker and published, 1935, " Pipunculidae (Dorilaidae) in Lindner "—Flieg. Palaearkt. Reg., 32 : 1-57, 3 pls. When Dr. Elmo Hardy published in 1943 his revision of the Nearctic Dorilaidae (Pipunculidae) in the Kansas Science Bulletin, 29, pt. 1, he included information from the work published by Dr. Marton Aczel in the Zoologischer Anzeiger, Leipzig, for 1939 and 1940. British entomologists were not acquainted with this,



owing to one, A. Hitler, non-entomologist. The work of Hardy and Aczel must be modified by the views of Mr. Collin of Newmarket in his 1945, " Notes on some recent work on the Pipunculidae (Diptera) " E.M.M., Vol. 81 : pp. 1-6. This last makes fascinating reading exemplifying the working of the Opinions of the International Congress for Entom. Nomenclature : for instance what happens when the description of a genus is too vague to be recognizable. Leaving that, in the following list, except where otherwise stated, records are from the collection of Claude Morley. M S denotes Monks Soham, N F New Forest. An asterick denotes Suffolcian. Brit. spp. over 40. Genus : CHALARUS, Walker ( = A T E L E N E V R A Macquart). Species: *spurius, Fall. Stated by Colyer and Hammond to be a parasite of a leaf-hopper.

Two specimens in Mr. Morley's collection labelled M S dining-room window, 9.vii.46 and M S window dusk, There may be some error of identification here, however, as Verrall associated the species with the only British Cicada, which is found only in the N F . Genus : PIPUNCULUS, Latr. ( = D O R I L A S , DORYLAS).
