The Irish Naturalist. 



[Nov., 



In the chapter on names and classification, Mr. Tutt makes the 

 astonishing statement that " butterflies in common with all other insects 

 have two names by which they are known all over the world." How 

 devoutly soever we may wish this were true, it w^ould perhaps be as 

 correct to say that no two entomologists use the same two names for 

 any species ! Mr. Tutt, doubtless quite correctly, has followed Con- 

 tinental and American writers in breaking up several of our old genera, 

 such as Vajiessa, Lyccena, and I'heda ; as he points out, it is wrong to 

 continue to " lump " species — however few — under the same generic 

 name when they really deserve separation. But alas for uniformity in 

 nomenclature I Mr. W. F. Kirby^ has recently published a popular book 

 dealing with the same question, and here is a comparison of the nomen- 

 clatures of the British Lyc^nidse as given by these two authorities : —
