near japonicus, Wiedem., but its smaller size is against 

 this sii])position. 



The nomenclature of some of the European species, more 

 especially of C. italicus, Mg., is most confusing. As regards 

 the latter 1 have followed Loew, who gives at some length, in 

 Verh. zool.-bot. Gesell. Wien, viii. p. 680, his views as to the 

 synonymy. Gobert and other authors have not followed 

 him, but still used the old luvnie Tabanus mannorafus, Rossi 

 (Faiuia Etrusc. ii. p. 312, 1820), which he rejects cntireh\ 

 Chnjsops fenestratns, Fabr. {Tabanus), he had no knowledge 

 of. He gives a full description of a species he believes to be 

 italicus, Meig., and suggests that C. marmoratus, Meig., as 

 described by this author, may be the same as a species 

 he describes under the name of perspici/hn'ls. Gobert 

 suggests that the latter is only a variety of C. if aliens, Meig. 

 (his marmoratus^ and considers the smaller size of the apical 

 spot of the wing, given by Loew as one of the chief charac- 

 teristics of pe7'spicillaris, is an untrustworthy distinction ; 

 this conclusion is borne out by a comparison of the specimens 

 in the British ]\Iuseum Collection, which are chicHy distin- 

 guished from C. italicus, Meig., by their smaller size and the 

 lighter colour of the abdomen in the females.
