262 Mr. W. W. Saunders on the 



I am doubtful of the necessity of the dividing this genus into 

 sections, otherwise than for the sake of discriminating the species, 

 for the Necera seems to be in form intermediate between the 

 divisions 1 and 3 of E. Doubleday and the new species lineata, 

 which, from its peculiar colouring and form, I am unable to include 

 in either of Mr. Doubleday's divisions, and which I make into a 

 fourth division, is again an intermediate form, and must follow 

 the division including Necera. 



In the following table will be seen tlie arrangement which I 

 now propose for the species, with such information regarding their 

 sexes and native countries which I have been able to obtain. 

 From this it will appear that we have positive knowledge of the 

 sexes of two species, that we know the males only of four species, 

 and the females only of eight species. Naturalists who may be in 

 a |)Osition to observe these beautiful and interesting insects in 

 their native haunts would do science a good turn by studying the 

 species carefully, and obtaining some of the information so much 

 wanted regarding their transformations, sexes, habits and economy.
