...... have been adopted as genera by several writers in the 



Entomologists Record." 



So far as my experience goes, in the magazines of to-day, contri- 

 butors have no control over the nomenclature of their communications, 

 which is altered in accordance with the views of the Editor. One 

 very striking illustration of this must be well known to Mr. Butler, any 

 enlargement on the point is quite unnecessary. I think, therefore, 

 whatever may be the ultimate decision respecting the breaking up of 

 the genus A crony eta, that Mr. Butler must see that the position he 

 takes up, in making myself and others responsible for changes in 

 generic nomenclature, is quite untenable and must be abandoned. —

Nyssia zonaria in Antrim. — As the weather has been so very bad 

 I thought I would run up here for Zonaria, also to try the sallows. 

 These are quite useless, although well situated, being just at the edge 

 of a wood ; there is nothing at them night after night. Zonaria was a 

 week later in appearing than when I was here in '89, but very 

 abundant, large, and varied. I have them from almost white to dark 

 smoky all over. I believe this is the only Irish locality, and I am 

 sorry to say there is great fear of it being destroyed at no distant date 

 by building operations. The specimens here are certainly larger and 

 brighter coloured than those from New Brighton. — E. R. Curzon, 

 Howth, April loth, 1891. 



Variety of Pieris Rap^. — On July 19th, 1890, whilst sitting at 

 my own door netting the white butterflies that were sipping the sweets 

 of a large patch of Silene maritima flowers, that I might examine them 

 for varieties, I took one specimen that seemed to me to be quite 

 unique. It is a fine but not large female, the basal shadings and 

 apical patch are well-pronounced greys, whilst the three usual spots 

 are large and black. The special peculiarity of the specimen is that 

 it has a small but quite distinct grey spot rather low down and 

 between the inferior nervures of the hind wings. Under a pocket 

 glass these spots differ, one being four pointed, and the other five. 

 I do not propose to call this interesting aberration var. extra dot Mihi, 

 but desire to record it that observers may be on the look-out for 

 others. I am old enough to remember the discussions of more than 

 50 years ago, before Westwood & Humphreys' " British Butterflies" 

 was published in 1841, whether Metra, Step., and Sahellicc^, Step., were
