THE BULLETIN OF THE BRITISH MUSEUM 



(natural history), instituted in 1949, is issued 

 in five series corresponding to the 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 22 of the Entomological 

 series. The abbreviated titles of periodicals cited follow 

 those of the World List of Scientific Periodicals.
