published some notes on it in the Trans. Tyneside Nat. Field Club, iv, 

 1858 — 60, pp. 55, 56. He was of opinion that the species was intro- 

 duced by shippiDg, and established itself, as he found a young one in 

 September, 1856. I have not been able to find out whether it is still 

 to be found in this locality. Mr. Bold distributed specimens amongst 

 several collections, and there are eight in the Brit. Mus. Coll. given 

 by him. It will be interesting to know whether we may consider this 

 as a really British species now, or only as a casual visitor. 



iii. — LABIA, Leach. 

 The small number of joints in the antennae, and the simple cylin- 

 drical middle joint of the tarsi, distinguish this genus. It has only 

 one representative in Europe, and this also occurs in Asia Minor and 

 N. America. 



1. — Labia minor, Linne.

 Labia minor, Leach, Edinb. Encycl., ix, p. 118 ; Steph., Mandib., vi, 

 p. 8 ; Brunner, Prod, der Eur. Orth., p. 10, fig. 3. 

 Of small size, generally testaceous. Head fuscous. Antenna? fuscous. Articula- 

 tions 10—12 with the first two and last two or three paler. Pronotum with the 

 posterior margin rounded. Wings with that portion projecting beyond the elytra 

 long. Legs straw colour. Legs of the forceps $ remote at the base, incurved at 



the apex, with a few teeth on the inner margin. In $ contiguous at the base. 



Length, 6 — 8 mm. 



Its considerably smaller size readily separates this species from 



the other earwigs. It may be found plentifully flying in the day time 



about gardens and dunghills in June. It is widely distributed all 



over Europe.
