ORTHOPTERA OF THE CHANNEL ISLANDS. 



Although the Channel Islands cannot be considered as 

 belonging to the British biological area, still it will not be 

 out of place to notice the species of Orthoptera that have 

 been recorded as occurring there. As a matter of fact, how- 

 ever, very few species have been put on record, and it is 

 evident that the orthopterous fauna stands as much in need 

 of investigation in these islands as it does in so many parts 

 of the British Isles. Of the seventeen species reported (in 

 one or two cases doubtfully), four Stauroderus vagans, 

 Omocestus hzemoroidalis, (Edipoda cgerulescens, and Chorthippus 

 pulvinatus are not British Insects. The Orthoptera of the 

 Channel Islands at present known are : 



Forficula auricularia Linn. Guernsey and Alderney (Luff)-, 

 Sark (Shaw) ; seems to be common in all the islands (Burr) \ 

 var. forcipata taken in the Islands of Libou and Chapelle 

 Dom Hue (Luff).
