3IO British Dragonflies. 



species in poor condition. Of it De Selys says (" Revue," 

 p. lOo) that Stephens assured him that he took it near 

 London. Exact date and locality do not seem to be 

 forthcoming, but in any case the insect can only be 

 looked upon as a " casual immigrant." In general 

 colouring it closely resembles GompJius vulgatissimus, 

 but the build of the abdomen is very different in the 

 two species, as are also the shapes of the various yellow 

 markings. The male has remarkable anal appendages, 

 which are doubled in towards each other at right angles. 



4. Gomphus fiavipes, Charp. — In Stephens' collection 

 in the British Museum is a male of this species in 

 good condition. It was captured by Stephens near 

 Hastings, on August 5, 1818 ; and his "Illustrations of 

 English Insects," Vol. VI., contains a good coloured 

 figure of the specimen. Like the last insect, it is 

 simply a " casual immigrant " ; but the exact date and 

 locality give it a better standing. This insect closeh- 

 resembles G. vulgatissimns, but may be known from it 

 by the yellow legs streaked with black, by the dorsal 

 yellow spots being continued beyond the seventh 

 segment to the end of the abdomen, and by the 

 different arrangement of yellowish stripes on the front 

 of the thorax. 



5. Lestes viridis, Lind. — Of this species De Selys 

 (" Revue," p. 149) says that he saw in Mr. Evans' 

 collection a specimen, which the latter assured De Selys 

 that he took in England. Evans' collection passed into 

 the hands of the late Mr. J. C. Dale, and Mr. McLachlan 

 says that his son (Mr. C. W. Dale) cannot now trace 

 it. (E. M. M., 1884, p. 254.) In the Entomologist
