 those of the female, with the exception of the antenna on the left 

 side male ; the rudiments of the wings are longer on the left side.

XXX. Extracts from a Paper by Zeller published in 

 the Linnata Entomologica, vol. 3, on the " Leaf -mining 

 Tinese, with Eye-Caps'^ {Augendeckeln), ivith Remarks 

 by H. T. Stainton, Esq. 



[Read July 3, 1848.] 

 My object being to draw attention to the different species and 

 their habits, in order to lead to the discovery in this country of 

 those which are still unknown to us, I shall merely quote the 

 distinguishing characters of those species not previously described 

 as indigenous. Zeller's paper includes the following genera : 

 Lyonetia, Phyllocn'tstis, Cemiostoma, Opostega, Buccidatrix, Nep- 

 ticida, Trifurcula, and Tischeria, corresponding to portions of our 

 genera Argyromiges, Microset'ia, and Aphelosctia. 



In his genus Lyonetia he has four species, two of which only 

 are known to us.

This is the species described by me under this name in the 

 Zoologist, p. 2159, and identical with the autumnella of Curtis, and 

 the ntvella and sem'iaurella of Stephens, which latter is the variety 

 cereella of Treitschke. 



" This species is very widely dispersed, and probably abundant 

 in many places, but not sufficiently observed. 



"The first specimens in the year I beat from birch in the first 

 days of May, but scarce and only the varieties. After that, 

 Cferckella flies from June through the whole of the summer and 

 autumn. I beat it abundantly from the wild apple and pear ; but 

 mostly from birch bushes. 



" The variety cereella, not scarce in several places in Tuscany 

 in March, April and June (Mann)." 



It appears thus, from Zeller and Mann's observations, that the 

 variety cereella (our semiaurella) occurs in the early spring in 

 March, April and May, but not the typical Clerckella; the same
