the llev. Knt. France), and among other authors of short papers on 

 various families of diptera may be mentioned the names of Hendel, 

 Strobl, and Czerny, 



Papers on morphology and histology have been published by Noack 

 " Beitriige zur Entwicklungsgeschichte der Musciden," and by Wahl 

 " Ueber die Entwicklung der hypodermalen Imaginalschreiben im 

 Thorax und Abdomen der Larve von Eristalis, Latr," {Zeitschr. Tl'/.ss. 

 Zool. Lci})zi(j); and by Escherisch "Ueber die Bildung der Keimbliltter 

 bei den Musciden " {Acta Ac. German, 69 pp., 3 pis.) ; while among 

 other writers on the same subjects may be mentioned the names of 

 Vallc, Enderlein, Meijere, and Miiggenburg. 



The interest taken in the question of the dissemmation of malaria 

 by mosquitoes has induced people to closely investigate the anatomy 

 and physiology of the mosquito (AiKijilwle!^), and the results have been 

 published in such papers as those of Christophers {Rep. Malar, ('ovi)n. 

 Fioi/. Soc), and Nuttall and Shipley {Joiirn. Hygiene Cambriihie), while 

 the whole question of the mos(]uito-malavial theory has been attacked 

 from all sides and a quantity of literature published upon the subject. 

 It is probable that the interest this question has caused people to take 

 in mosquitoes will be the means of the Culicidae becoming one of the 

 best worked out families of the diptera. F. V. Theobald's " Mono- 

 graph of the ( itUcidae or Mosquitoes " (London : 8 vols. Printed by 

 Order of the Trustees of the British Museum) is a step — and a good 

 long one — in that direction. 



Kertesz in the Termes Fnzetek, and elsewhere, has published several 

 papers on south Asiatic diptera, and he has also published a useful 

 catalogue of the described species of Pipunculidae of the world. Miss 

 Ricardo, in the Annals of Xat. Hi^t., has given further notes on the 

 I'angnninae in the British Museum collections, and Stein has written 

 on Walker's Antlicnnyidae in the British Museum (Zeitschr. Ili/ni. 

 Dipt.). Among American writers, Coquillet has published various 

 notes and a " Systematic Arrangement of the Families of Diptera " 

 [Proc. U.S. Xati())i. Mas.), while Doane, Tyler- Townsend, and others 

 have contributed towards a knowledge of the north American fauna of 

 diptera ; Hunter's ('atalmjue of Snntli American Dijitera, of which he 

 has published a continuation, should prove a useful compilation. 



As far as the British Isles are concerned the most important work 

 published during 1901 was Verrall's volume on the Plati/iiezidar, 

 Pi])nnciilidae, and Syrphidae of Great Britain ; by its aid it should be 

 possible for the British collector to name his captures in those families 

 far more easily, and it will form a foundation upon which the British 

 student can build, while the continental entomologists will undoubtedly 

 find it of considerable assistance in the study of their fauna of diptera. 

 The small band of British workers have added several species to their 

 " List," among which may be mentioned Atlierix cra^isipes, Mg., 

 Lophosia fasiiata, Mg., and Pachyyaster iiiero)iielas, Duf. ; Austen has 

 published a descriptive paper {Fnt. Mo. May.) upon the last species, 

 founding a new genus Neopachyyaster for its reception, and calling the 

 species Xeo/)ae/iyyaster ineroiiielaena. In the same magazine I have 

 endeavoured to distinguish the three British species of Heteroinyza, 

 while Wainwright has given some notes on British TacJtinidae,BvAd\ey 

 notes on British Trypetidae, and Henderson has written on the 

 Tipulidae in the west of Scotland.
