Ampyx nudus Miirch., A. iumidus n. sp. Brachampyx u. g. 



The author makes the following remark: "If, in the end, all the five 

 ringed species should prove to have long heads, and those with 6 thoracic 

 segments to have short and rounded ones, the latter section may be con- 

 veniently distinguished from the former as a subgenus, under the name of 

 Brachampyx . 



The author erroneously included the type of the genus, Ampyx ncutufus 

 Dalm., in his new subgenus; the term is misplaced and should be aban- 

 doned.
