 Other Neuroptera : Sialis fuliginosa, one; *Panorpa meridionalis, 

 three males, three females ; Megalomus hirtus, one, provisionally 

 so named by Mr. Morton, but it does not entirely agree with the

Two living larvae of the ant-lion (Myrmeleon formicarius) from 

 La Granja were given me by Dr. Chapman on September 22nd. 

 After passing several months without food, one produced an 

 imago of good size about the following midsummer. 



For great assistance in identification I have to thank Mr. 

 K. J. Morton, of Edinburgh, especially in connection with the 

 specimens belonging to the less known and more difficult groups, 

 which, though few in number in this collection, were none the 

 less interesting. 



ON THE DARK FORM OF ISCHNURA ELEGANS 



(FEMALE). 



By F. W. and H. Campion. 



In October, 1904, we drew attention in these pages (vol. xxxvii. 

 p. 252) to the occasional occurrence in Epping Forest of a dark 

 form of Ischium elegans, female. We have again met with this 

 form during the present year, specimens having been taken on 

 June 25th, August 13th, and September 3rd, one on each occasion. 

 The second specimen was at the time of capture attached per 

 collum to a normal male ; this was evidently an old individual, 

 as it had a worn and dusty look, and had the left fore wing torn. 

 The association of this dusty appearance with ragged wings was 

 also noticed on July 22nd in the case of two females of Agrion 

 puella. The state of the example of August 13th and a re-
