been sent for inspection to the writer of the Erlangen Article 

 — and confirms Panzer's statement, in the Kritische Re- 

 vision, that his unicolor was the lugubris of Fabricius. This 

 species is at present known as a Pemphredon Ltr., being in 

 fact the Type designated for that genus by its author in 

 1804-5, and again (under the name Ce?no7ms unicolor Pzr.) 

 in 1810. Cemonus and Pemphredon are therefore synonyms, 

 with the common Type lugubris F. (= unicolor Pzr,), on 

 the authority of Panzer, Latreille, and also Jurine. The 

 name Cemonus Jrn. has validity as against Pemphredon Ltr., 

 because it was published as a monotypical genus in May 



1801, whereas Pemphredon Ltr., though the name itself 

 appeared earlier (viz. in 1796), received no species until 



1802, when lugubris F. and leucostoma F. were made 

 exponents of it. 



[The name Cemonus is still sometimes used rather as sub- 

 generic than as generic, unfortunately in connection with a 

 group not containing lugubris, but containing several other 

 species, two of which till lately were not distinguished and 

 together were called unicolor. This " unicolor " was a 

 homonym of " Crabro unicolor Panzer" (= lugubris F.), 

 and should therefore be discarded — as in practice it has 

 already been.]

Oxybelus was published by Latreille in 1796, but without 

 associated species, and was first vahdated by Jurine in 

 1801 (Erlangen List). Jurine gave three exponents, and
