In the Tring Museum 1 $ from the Kikuyu Escarjiment, British East Africa,

Butler, I.e., says : Our example bears a label by tlie collector bearing the 

 following inscription: '■'■ Adterontia spei S. Only two ? specimens taken in 1857 

 (one of them lost). I have not observed that peculiar chirping noise ; had they 

 chirped I am sure I would have observed. Query, Does the S only chirp, and 

 the ? not?— 11'. %s." "I have not thought the MS. name applicable, and 

 therefore have not used it." 



The reader will have guessed, without being told, that spec, and not spri, is 

 written on the label. However, if Butler mistook spec, for a manuscript name spei 

 which he did not think applicable, why did he publish it?
