in different periodicals, and among them many species from the 

 South-Asiatic regions. 



A Dipterologist of recent times was J. M. F. Bigot in Paris. 

 He possessed a very extended collection of exotic Diptera , which 

 after his death (in 1892) has come into the hands of Mr. G. H. 

 Verrall in England. Bigot wrote much on Dipterology , especially 

 in the Annales de la Societe Eniomologiqiie de France'^ numerous 

 species were described and many new genera were established by 

 him. Moreover he attempted to make systematical arrangements. His 

 works , however , often show a want of exactness , and those , 

 who will make use of them, must take care to do it with cir- 

 cumspection. 



Among the still living Dipterologists , who wrote papers on 

 South-Asiatic Diptera, we may give a first place to Baron G. R, 

 OsTEN vSacken. Besides many works, in which he has contributed 

 much to the knowledge of the Dipterous fauna of North America 

 and to I he systematic of the Tipulidae, he has most carefully 

 worked out, in the Annali del Mtiseo civico di Genova , the D'npiera., 

 collected by Prof. 0. Beccari and others in the Malayan archipelago 

 and, in the Berliner Entomol. ZeifscJirift, a large collection made 

 by Semper on the Philippine islands. 



Professor F, Brauer, in several papers, entitled: Die Zwel- 

 jiilgler des Kais.Museiims in Wien, has elucidated numerous types 

 in that Museum, The most recent of these papers, in which J. E. 

 von Bergenstamm is mentioned as collaborator , concern the family 

 ot Muscidae calypterae (which they call Muscaria schizometopa). 

 In this highly important labour the faults of the hitherto adopted 

 systematical arrangement of this large and difficult family are 

 clearly brought to light; attention is given to some characters, 

 which till now had been neglected; and numerous, perhaps too 

 many, new genera are established; besides several new species, 

 among which some of southern Asia , are described by the authors. 

 The study , however , of this labour is not easy. 



Finally mention should be made of F. Jaennicke , who has eluci- 

 dated many of the exotic Diptera in the museums of Frankfurt a. M,
