eyes and sometimes the labrum and clypeus and the space between the 

 antennae, which are dirty yellow. Legs yellowish, tarsi darker. Abdo- 

 men luteous, the apex black above. Wings smoky, tegulre black. The 

 has one more joint in the antennas than the ? ; they are also testa- 

 ceous beneath, and the abdomen has the dorsal surface black. 

 Length If 2 lines. 



This species is very variable in coloration, some 

 specimens having the head and abdomen almost 

 entirely black. I have one 3 from Clydesdale which 

 is half the usual size ; the wings are almost hyaline, 

 and the basal half of the femora and the hinder tarsi 

 are black. 



The larva mines the leaves of the alder, in which it 

 lives alone or in company with two or three others. Two 

 broods are met with, the autumnal one being the most 

 numerous. It is an abundant species everywhere. 

 Campoplex cerophagus, Gr., and Chrysocharis albipes, 

 Gir., are given by Giraud as parasites. 



Continental distribution : Sweden, Germany, France,
