Mr. Hudson considered this paper on the Alenrodido! a most valuable 

 contribution. He was glad that Mr. Maskell had turned his attention to 

 this interesting family. There were two species of moths in England 

 only distinguished, like the Aleurodidce, in the immature stage. 



Sir J. Hector said this was an important paper. Numbers of trees 

 were being destroyed by these minute insects, and the curious thing was 

 that they could onl}' be recognised in the immature state; it was the 

 reverse of what was usual. 



Mr. Travers said that Captain Hutton had pointed out that the 

 Planarians are only distinguished by tlieir colours. They also differ in 

 the immature stage where they do not in the perfect insect. 



Mr. Maskell, in reply, said that possibly there may be differences in 

 the full-grown form, but, if so, it was exceedingly difficult to distinguish 

 them. He said that in hot weather these insects were most numerous, 

 and there was only one generation in tlie year.
