small size is of no importance, as L. pyre- 

 nceum varies greatly in this respect. In M. 

 Bedel's opinion the insect cannot be regarded 

 as more than a variety or subspecies of L. 

 fyrenceum. Both forms occur in France : 

 L. 'pyrennum in the Pyrenees, Gascony, and 

 on the Central Plateau ; ajid L. troglodytes 

 in Normandy (Forest of Cerisy, Calvados). 

 The latter name is sunk as a synonym in 

 Hcyden, Reitter, and Weise's Catalogue 

 (1891).

HERMAPHRODITE EARWIG (CHELISOCHES MORIO, Fabr.). 

 BY MALCOLM BUKE, F.Z.S. 



While looting through a number o£ earwigs which I have recently 

 received from Borneo, Java and Celebes, my attention was struck by 

 the curious shape of the forceps of two Chellsoches morio, Fab. They 

 are distinctly hermaphrodite, the right branch being male in form and 

 the left female. The number of visible segments is nine, as is the 

 case in male earwigs, whereas the female has only seven visible. 



Brunner remarks (Prod. Eur. Orth., p. 4) that hermaphrodite 

 forms are not uncommon in earwigs, and de Bormans records the phe- 

 nomenon in the fine species Labidura (?) pugnax, Kirb., from Burmah 

 (Ann. Mus. Civ. Gen., 2nd Ser., vol. xiv [1894], p. 377), in which case 

 also it was the right branch that had the male form. I am not aware 

 whether asymmetry occurs also in the internal sexual organs. 



Of the specimens referred to, one is from Bua-Kraeng in Celebes, 

 and the other from Pengalengan in Java. 



ChelisocJies morio is a very variable and a widely distributed spe- 

 cies, being found in all the Islands of the Pacific and Indian Oceans, 

 and in Japan, Burmah, New Zealand, Mauritius, east coast of Africa, 

 and recently a pair has been taken in one of the artificially heated 

 houses at Kew Gardens
