M. Harris, Exposition of Engl. Insects, pl. xii, f. 3, figured the nympha of 
ZE. grandis. 
E. Donovan, the Natural History of British Insects, Vol. II. pl. 44, figured as 
Libellula depressa, the nympha of Aschna (perhaps cyanea or grandis). The 
figure is good, except some minor errors. : 
Kirby and Spence, Introduction, ete., Vol. III. pl. 16, f. 5, figured as Libellula, 
the nympha of an Aschna. Described in letter xxx. 
(Rennie), Insect Transformations, p. 137, has a copy of Roesel’s transformation of 
ZK. grandis. 
W. F. Evans, British Libellulina, pl. 1, f. 20, figured the nympha of Anax for- 
mosus as Aéschna. 
Leon Dufour, Etudes anatom. and physiolog. sur les larves des Libellules. Ann. 
sc. natur. ser. 3. Vol. XVII, pp. 65-110, pl. 3. He is the first to attempt a 
systematical arrangement of the nymph. He described and figured A‘. gran- 
dis (= A. formosus), A. De Geerii (4. rufescens), Ai. inominata (AZ. cyanea). 
H. A. Hagen, Stettin. Entom. Zeit. Vol. XIV., has given a review of the lit- 
erature, and described seven species,— A. formosus; A%. cyanea, affinis, 
rufescens, grandis ; B. pratense; Gynacantha spec. 
F. Brauer, Neuroptera Austr. pp. xiv.-xvi, gives an excellent review of the 
nymph. He had raised himself a large number of species, and to him is due 
most of our knowledge about the species. The nymph described by Hagen 
were mostly communicated to him by F. Brauer. 
Fr. Sanborn, Tenth Ann. Rep. Mass. Board of Agric., p. 149, figured the nympba 
of /E. clepsydra (= AZ. constricta). The figure is reproduced in A. 8. Packard’s 
Guide, p. 602. 
Miss Olga Poljetajewa, Mémoirs Russian Entom. Soc., Vol. XI. (in Russian lJan- 
guage) described the Odonata from St. Petersbourg and the nymph of “AE. 
juncea, viridis, both shortly, and of A®. 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, Rambur, Stephens, Newport, New- 
man, and in a large number of popular works; but they are not detailed enough for 
species or genera. Fossil nymph are figured and described. The literature is given 
by Heer and Hagen.
