From the specimens I have seen (from Forfarshire and Ross-shire), I should 

 refer this to the Z. trifolii (the "early trifolii ") of Mr. T. H. Briggs' paper in 

 Trans. Ent. Soc, iv., 1871. The Forfarshire examples were taken on the coast 

 near Arbroath, in company with filipendu Ice and nubigena, at various dates (the 

 captor, Mr. A. Guthrie, informs me), from the last week of June to August 26th, 

 at which date they were much worn. The date of appearand of Mr. Briggs' 

 "early trifolii' 1 '' is from the second week in May to the second week in June. 

 The other localities where trifolii has occurred in Scotland are the coasts of 

 Kincardineshire (J. W. H. Traill) and Ross-shire (A. Davidson). Z. lonicerce. 

 should occur.
