anyone is lucky enough to meet with it, by the very highly 

 developed appendages, and (except from Agrion hastulatum) by 

 the spots on the dorsal surface of the second segment (figs. 2, 3, 

 4, 5). It is strange that Mr. Edelsten should have taken one 

 in 1902. He placed it in spirit to preserve its colour, intending 

 to send it to me ; but it came to grief on his journey home, and 

 it was not till after seeing Mr. Browne's specimens that he 

 recognized the identity of his capture. 



A female Sympetrmn fonscolomhii was taken by Mr. W. C. 

 Boyd in June, 1903, near Trewoofe in W. Cornwall. 



Mr. J. J. F. X. King has taken again A. hastulatum in 1903 

 in Aviemore.
