Mr. M. Burr— Notes on the Forficularia. 83 



This species, for which I am indebted to my friend M.. Secl- 

 drayers, of Brussels, in size and appearance resembles 

 F. auricular ia and F. decipiens. The unarmed and much more 

 strongly dilated forceps distinguish it from F, auricularia • 

 the presence of wings and the very strongly bowed forceps 

 distinguish it from F. decipiens, to which perhaps it stands 

 nearest ; its larger size and strongly bowed forceps separate 

 it from F. lurida. The general appearance of the forceps 

 recalls that of F. circinata, Fin., but they are more strongly 

 arched and the insect is larger.
