slender black line passes centrally along the sides of the posterior 

 segments, though occasionally interrupted ; another black line, 

 below this, is never interrupted : the wings in both sexes have a 

 saffron tinge at the base, — in the females, extending along the 

 costal margin : the stigma is smoke colour : the legs are yellow, 

 with slender black lines, excepting the tarsi, which are totally 

 black. (Length 16 to 17 lin. ; breadth 25 lin.) 



This species is also abundant round London, but never seen 

 in company with the last. I have examined the authentic 

 Linnffian specimen, and find it does not perfectly agree with 

 this insect ; but probably time has so altered its colours, that it 

 would be scarcely fair to introduce a new name.

Libel, basalis. Steph. Syst. Cat. I. 309. 



Male and female, dull yellow, approaching in parts to olivaceous : 

 a series of irregular black spots, on the sides of the posterior seg- 

 ments, form an interrupted line : the meso- and metathorax 

 are likewise marked with black, in the same manner as Symp. 

 vulgatum : the wings are beautifully stained with saffron-colour 

 at the base, and along the costal margin : the stigma is smoke- 

 coloured : the legs are black, with the exception of the under 

 surface of the profemora, in the female, which is yellow, and the 

 coxae and trochanteres, which are of peculiarly pale and delicate 

 straw-colour. (Length 15 lin. ; breadth 22 lin.) 



Mr. Stephens, who kindly transmitted me his typical speci- 

 men, has the credit of first noticing this species as distinct 

 from the others, and I have adopted his name, although I 

 should have preferred a more distinguishing one, as the one 

 he has chosen is more or less applicable to every species of the 

 restricted genus Libellula. It does not appear an abundant 

 species, though occasionally found near London. I have never 

 met with it.
