cionus woora. 65 



called lont/icollis, Bris., in all the British records of the same. He 

 states that the typical form only occurs in the western Mediterranean 

 region, i.e., in the South of France and Spain. The var. )iiontanus, 

 which he described in his paper (pp. 195-6), extends over the 

 mountains and hilly parts of Austria and Germany, but appears to 

 entirely fail in the plains. He possesses a pair of the so-called 

 lonf/icollis, Bris., from Portsmouth, and he says these are his var. 

 montanus, which is a larger and more robust insect than the type. 



I have described the new species, which I have called woodi in 

 honour of its discoverer ; and have drawn up a simple table of all the 

 British species of the genus to fit in with that of Fowler, including 

 both the new species, and the var. montanus, Winglm., of C. 

 ibngicollu, Bris.
