There remain to be reviewed the Zygopterides, that is, those 

 dragonflies in which the fore- and hind-wings are more or less alike. 

 They are contained in three and a half drawers, and comprise no less 

 than 193 insects. These, with the Anisopterides already treated, 

 bring up the total in the " Dale Collection " to 361. 



Calopteryx vir go.— There are nine specimens, a male (171), a male (173) with 

 uncoloured wings and greenish body, and one female (175) being without labels 

 A male (IfiO), has a blank green label, and Walcott. 1843 (J. C). A male (170) is 

 from Cosmore Com"-. 1818 (J. C). A male (176), with uncoloured wings and

 appearance has " anceps Ste. \. Vesta" (at side). A female (172) has two 

 labels — New Fo., 1842 (J. C), and Jun. 1842 (J. C. filled in),^ while another

Lestes sponsa. — Thei'e appear to be twenty examples of this insect, which

 females (200, 201, 214) bear no labels. Two males (195, 213) and two females 

 (215, 216) are labelled Norfolk July 1905 (C. W.), and two females (202, 217) 

 are labelled in the same way, but have in addition, Norfolk (at side) ; the last of 

 these females appears to have something wrong with its anal appendages. Of six 

 males (196) is labelled Chant 46; (197) New For. 1844 (J. C.) ; (198) July 2 

 (or 21) 1844 (J. C. filled in) ; (210) Aug. 1816 (J. C. filled in), and Killarney
