414 Rev. F. D. Morice and J. H. Durrant on the 



belonging to the genus known as Cimhex Olvr. Crabro 

 Gffr. (1785) and Cimbex Olvr. (1790) are synonyms, but 

 since § Crabro GfEr. (1785) is invalid as homonymous with 

 Crabro F. (1775), Cimbex Olvr. must be accepted as the 

 name of the genus of which lutea L. is the Type.] 



In recent arrangements of Crabro F. {sens, lat.) cribraria 

 L. is called not a Crabro, but a Thyreopus Lep. (following 

 Lepeletier 1834), the name Crabro {sens, strict.) being 

 reserved for another group {formosus Auctt., etc.) — before 

 saying more we await Kohl's forthcoming Monograph of 

 the Crabronidae, merely suggesting that Crabro F. should 

 not be separated from its Type cribraria L,

Panzer, Fauna Ins. Germ. (52-24), figures as Crabro 

 unicolor (but describes as Sphex unicolor), an insect, which 

 in Krit. Rev. (186-7), he states to be a Cemonus Jrn., and 

 identical with Pemphredon lugubris F. (Syst. Piez. 315). 

 The neuration of his figure is so obviously incorrect that 

 no conclusion can safely be drawn from it, nor in char- 

 acterising Cemonus in the Krit. Rev. (186-7) does Panzer 

 mention the neuration at all. The true neuration of 

 " unicolor Pzr.," the Type of Cemonus is correctly given 

 by Jurine on Plate 4 fig. 28 — one of the Plates which bad
