calls it. It is perhaps intended for a nymph of this species, but 

 does not resemble it in shape. The eyes are like round beads 

 at the fore corners of the head, which ends in a point in front. 

 The distal edge of the mask is round. The wing-cases are 

 small.]

NOTES ON THE GREA.T EARWIG AND OTHER BRITISH 



FORFICULIDiE.

Labidura riparia, Pall. = gigantea, Fab. — This fine species of 

 earwig has hitherto been found only in the vicinity of Bourne- 

 mouth, where examples were secured by the Eev. W. Bingley, 

 on the 7th of July, 1808; these were exhibited the following 

 November by IVIr. G. B. Sowerby at a meeting of the old Ento- 

 mological Society. IVIr. Bingley, in a letter to the Treasurer of 

 the Liunean Society, states that as he was walking on the beach 

 west of Christchurch, just at the close of the evening, he saw two 

 or three large insects running along the sand, about or rather 

 below high-water mark, and from their size and manner he took 

 them to be young mole crickets. Surprised at seeing such 

 insects in that situation, he examined them as well as the light 

 would permit, and, by their immense forceps and size, found 

 them to be a species of Forficnla hitherto undescribed as British. 

 He took home some specimens, and ascertained them to be the 

 Forficnla gigantea of Fabricius. Mr. Sloman, a friend of Mr. 

 Bingley, sought for them afterwards in the same place, and 

 found a great number concealed under large stones on the sands. 

 Mr. Bingley put three or four together into his box ; and the 

 consequence was that one of them was devoured by the rest,
