1772. M. Harris, Exposition of Engl. Insects, ^\. xii., f. 3, figured the nympha of 



M. grandis. 

 179.3. E. Donovan, the Natural History of British Insects, Vol. II. pi. 44, figured as 



Libellula depressa, the nympha of iEschna (perhaps cyanea or grandis). The 



figure is good, except some mmor errors. 

 1826. Kirby and Spence, Introduction, etc.. Vol. III. pi. 16, f. 5, figured as LibeUula, 



the nympha of an ^schna. Described in letter xxx. 

 1830. (Eennie), Insect Transformations, p. 137, has a copy of Eoesel's transformation of 



JE. grandis. 

 1845. W. F. Evans, British Liljellulina, pi. 1, f. 20, figured the nympha of Anax for- 



mosus as j$^schna. 



1852. Leon Dufour, Etudes anatom. and physiolog. sur les larves des Libellules. Ann. 



sc. natur. ser. 3. Vol. XVII, pp. 65-110, pi. 3. He is the first to attempt a 

 systematical arrangement of the nymphte. He described and figured JE. gran- 

 dis (= A. formosu,s), JE. De Geerii (JE. rufescens), JE. inominata (JE. cyanea). 



1853. H. A. Hagen, Stettin. Entom. Zeit. Vol. XIV., has given a review of the lit- 



erature, and described seven species, — A. formosus; JE. cyanea, affinis, 

 rufescens, grandis ; B. pratense ; Gynacantlia spec. 



1857. F. Brauer, Neuroptera Austr. pp. xiv.-xvi., gives an excellent review of the 

 nympluie. He had raised himself a large number of species, and to him is due 

 most of our knowledge about the species. The nymphie described by Hagen 

 were mostly communicated to him by F. Brauer. 



1862. Fr. Sanborn, Tenth Ann. Eep. Mass. Board of Agric, p. 149, figured the nympha 

 of JE. clepsydra (= JE. constricta). The figure is reproduced in A. S. Packard's 

 Guide, p. 602. 



1879. MLss Olga Poljetajewa, Memoirs Russian Entom. Soc, Vol. XL (in Russian lan- 

 guage) described the Odonata from St. Petersbourg and the nymphre of JE. 

 juncea, viridis, both shortly, and of ^E. grandis very detailed and complete. 



General descriptions and figures are to be found in the works of Vander Linden, Char- 

 pentier, Burmeister, Latreille, Westwood, Lacordaire, Eambur, Stephens, Newport, New- 

 man, and in a large number of popular works ; but they are not detailed enough for 

 species or genera. Fossil njnnphiB are figured and described. The literature is given 

 by Heer and Hagen.
