forms, 6 are scarcely more than races of European and Siberian forms, 
16 have completely European facies, the remainder belonging to the 
eastern subtropical division. There are 19 Libellulina , 5 Corduliina , 10 
Gomphina , 10 ADschnina , 6 Calopterygina , and 17 Agrioniha. An appendix 
notices a few species from North China, &c. 
A brief notice of the fossil Odonata of the Florissant and Green River 
Tertiaries is given by Scudder in P. Bost. Soc. xxi. p. 409. All the 
Green River forms pertain to the Legion Podagrion , whereas those from 
Florissant are divided between “ Podagrion ” and “ AgrionP All are 
decidedly subtropical in facies.

An amplification of the author’s views as to the characters and limits 
of these genera, and especially with regard to the transference, by De 
Selys, of certain species of Agrionoptera to Orthemis. Tabular charac- 
ters are given for a natural group of genera, composed of (1) Lyriothernis 
and Orchithemis , (2) Agrionoptera and Uracis } (3) Neurothemis , (4) 
Orthemis. 
Orchithemis , Calothemis , and Lyriothernis. De Selys, Ann. Ent. Belg. 
xxvii. pp. 142 & 143, replies to Brauer’s criticisms (vide supra ), and is of 
opinion that if it be thought convenient to retain these divisions as 
distinct, they may be constituted as follows : — Orchithemis should in- 
clude pulcherrima , Brauer, and pruinans , Selys ; in Calothemis should be 
placed bivittata , Rbr.,and meyeri and biappendiculata , Selys; Lyriothernis 
comprises acigastra , pachygastra , lewisii , elegantissima f priapea y and mag- 
. nijica , Selys, and cleis, Brauer. 
Libella albistyla , Selys. De Selys, l. c. pp. 101-103, considers albi- 
styla (Europe, China, and Japan), albicauda, Brauer (China), and speciosa, 
Uhler (China and Japan), scarcely distinct as varieties. L. zonata , Burm.

Libellula quadrimaculata . A further note on the notorious migration 
of this species is given by A. Newton, Nature, xxviii. p. 271, from obser- 
vations made at Malmo in Sweden. (Cf. also Ent. M. M. xx. p. 88).
