THE BULLETIN OF THE BRITISH MUSEUM 



(natural history), instituted in 1949, is 

 issued in five series corresponding to the Scientific 

 Departments of the Museum, and an Historical series. 



Parts will appear at irregular intervals as they become 

 ready. Volumes will contain about three or four 

 hundred pages, and will not necessarily be completed 

 within one calendar year. 



In 1965 a separate supplementary series of longer 

 papers was instituted, numbered serially for each 

 Department. 



This paper is Supplement 26 to the Entomological 

 series. The abbreviated titles of periodicals cited 

 follow those of the World List of Scientific Periodicals.
