iV. fureata, Fab., is considered by Tieber, Burmeister, Herrich- 

 Schafter, and Flor, to be a var. of N. gJaiica, Lin., but, though we 

 defer provisionally to their opinion, we think the matter has yet to 

 be proved by out-door observers. N. viarmorea, Fab., a form which 

 does not, as far as we are aware, occur in Britain, is also quoted by 

 these authors as a var. oi glauca. 



Species 3. — Notonecta maculata.
