II. — Notes on Exotic Chloropidae, By C. G. Lamb, 

 M.A., B,Sc., Clare College, Cambridge. 



The following notes are based on material from two sources. 

 The larger portion is the collection of Diptera in the Zoolo- 

 gical Department of Cambridge University, and will be 

 referred to as '' Cam. Coll." In 1904 Mr. F." Muir presented 

 a very large collection of Diptera from Africa to the Cam- 

 bridge IMnseum, and his specimens will be marked " F. ^\." 

 In addition, the Museum was indebted to Dr. G. A, K. 

 Marshall for many other specimens from the same region, 

 and there have been various other small accessory collections 

 incorporated from time to time. The other ])ortion consists 

 of specimens kindly submitted to the author by Dr. G, A. K. 

 Marshall — they are part of the extensive collection being 

 formed by the Imjierial Bureau of Entomology ; this will 

 be referred to as " Bur. Coll.'^ 



All the insects listed and described in the paper will be 

 deposited in the British Museum, and hence no indication 

 of the situation of the type-specimens will be given after 

 the descriptions; they will all be in the British Museum. 



The task of dealing with this family is enormously 

 lightened and simplified by the valuable and complete 

 monographs of Th. Becker, which bring the information
