Libellula Scotica. Leach. E. E. IX. 186, descr. 

 Id. Donovan. XV. PI. 52^, icon. 



Male, purply-black, with an oblique, yellow, elongate blotch on the 

 mesothorax ; another on the metathorax, besides several smaller 

 spots of the same colour : the decaton and protelum likewise bear 

 on each two distinct yellow spots : the wings are very clear, 

 without any saffron tint at the base. Female, olivaceous, with 

 the yellow spots on the anterior segments, as in the male ; the 

 posterior segments having the inferior portion black. The male 

 and female have the stigma of the wings, and the legs, entirely 

 black. (Length 12^ lin. ; breadth 19 lin.) {Mus. Soc. Ent.) 



Taken in Scotland and some parts of England.

Male, brilliant red. Female, olivaceous, the lateral portions of the 

 meso- and metathorax inclining to yellow, variegated with black 

 oblique lines : the acute keel of the posterior segments is tipped 

 with black, the lower portion is also inclining to black. In both 

 sexes the wings have a tinge of brown over the whole surface, and 

 a saffron-coloured spot at their base : the stigma of the males, 

 particularly, is bright red : the legs are black, with the under 

 surface of the profemora in the females excepted, which is yellow. 

 (Length 13 lin, ; breadth 21 lin.) {Mus. Soc. Ent.) 



This species is particularly abundant. I have examined no 

 London collection without observing specimens of it ; it is not 

 allied to any described species ; the red male instantly distin- 

 guishes it from S. Scoticinn, the black legs and diminutive 

 size from S. viilgatum.
