Note. The new species has great atfmity to Ch. equester 

 With, from Eastern Africa, especially because of the high tibia, 

 this being laterally seen nearly circular. According to Mr. With 

 who has been so kind as to compare specimens with the type of 

 Ch. equester, the differing characters are especially the following: 

 the West African form has only half the size of the East African 

 one, the hinder protuberance of trochanter is low and quite 

 rounded, the upper moderately strong and pointed (in Ch. equester 

 the hinder protuberance is long and pointed, the upper very high 

 and obtuse); the stalk of tiljia shorter (in Ch. equester very long).
