(Continued from p. 42.) 



2. E. Donovan: ' The Natural Historij of British Insects,' 

 1792-1813. 



In the sixteen volumes comprising this work we have pre- 

 sented to us a large number of generally well-executed hand- 

 coloured plates of British Insects, with accompanying letterpress 

 in English. It is got up somewhat in the same manner as 

 Curtis's later and well-known work, and is a decided advance on 

 that of Harris. 

 Vol. I. Pl. XXIV. P. 53. 



Libellula depressa ? = Lihellula depressa $ . 

 Plate XXXVI. P. 79. 



Libellula virgo (fig. 1) = Calopteryx virgo ^ . [It is called Lib. 

 picella ; but this is evidently a misprint for virgo, under which 

 designation it appears in the index.] 

 Libellula puella (fig. 2) = Pyrrhosoma nymphula. [By the figure 

 apparently a male.] 

 Vol. II. Pl. XLIV. P. 21. 



Larva of Libellula depressa = nymph of one of the MschnidcR. 

 Vol. III. Pl. LXXXI. P. 23. 



Libellula depressa 5^ — Libelhda depressa 3- . 

 Vol. V. Pl. CLXVI. P. 77. 



Libellula grandis = Mschna cyanea ( J apparently). [This insect 

 cannot be .^. grandis, for it is a blue-spotted species, and has 

 hyaline wings. In some respects it bears a little resemblance 

 to j3^. juncea : but, judging by the small pterostigma and otber 

 points, there is little doubt that it is intended for jE. cyanea.] 

 Vol. X. Pl. CCCXXXVII. P. 29. 



Libellula vulgata (fig. 1) = Sympetrum striolatum $ . [No doubt 

 it is intended for tbis species of the genus Sympetrum, if only 

 because it is described as very common.] 

 Libellula grandis (fig. 2) = Mschna grandis ^ . [The insect is 

 figured with saffron wings.] 

 Vol. XII. Pl. CCCCVII. P. 39. 



Libellula quadrimaculata = Libelhda quadrimacuJata 5 . [The 

 unsuffused, Scotch form.] 

 Pl. CCCCXV. p. 61. 

 Libellula senea = CorduUa anea ( ? , apparently). [There are two 

 figures, the lower one with yellow wings, Donovan calls the 

 latter a variety ; but the variation is probably due to the figure 

 being taken from an immature specimen.] 

 Pl. CCCCXXIII. P. 81. 



Libellula forcipata = Gomphus vulgatissimus ( 5 , apparently). 

 [Below the figure of the imago is one of a pupa, as Donovan
