PHYLLOTOMA OCHROPODA. 285 



The egg is deposited near the edge or tip of a birch 

 leaf, in which the larva lives afterwards as a solitary 

 miner. There are two broods in a year, the first in 

 June and July ; the other later on in the autumn, the 

 larvae being found as late as October. 



It is a commonly distributed species, occurring from 

 the London district to the north of Scotland. 



Continental distribution : Sweden, Germany, Hol- 

 land. 



2. PHYLLOTOMA ACERIS.

Black, shining. Antennae ten to twelve-jointed, fuscous testaceous at 

 the apex. Wings half smoky ; pronotum lined with white ; tegulas 

 obscure white ; abdomen black, except that the edges of the segments 

 are sometimes faintly white, but there are no distinct dots. Legs 

 white, femora for the greater part black. 



Length 1 If lines. 



The cT I have never seen. The face has more black 

 on it than in nemorata, there being no white above the 

 antennae. 



The larva mines the leaves of the maple in June and 

 July. It is common in the London district, and pro- 

 bably elsewhere. At Brussels in 1877 it appeared in 

 great abundance, so much so that considerable damage 

 was done to the trees, nearly every leaf, even those 

 growing fifty feet up the trees, being mined by the 

 larvae, which curiously enough only appeared in that 

 district for the first time in that year. Cf . McLachlan, 

 E. M. M., xiv, 120. 



Continental distribution : Germany, Belgium.
