From nemorata and aceris, ochropoda may be known by the 

 colour of the feet, the black tegulse, and pronotum (in the female), 

 and the greater number of joints in the antennae. From the 

 following sj)ecies it may be known by the absence of luteous 

 colour on the abdomen. 



For this species I am indebted to Mr J. E. Fletcher, of Worcester, 

 who discovered the larv?e mining the leaves of the black poplar in 

 the autumn. They do not differ in any noticeable particulars from 

 the other larvae. This is the first time that the habits of the 

 species have been described. 



P. ochropoda I have never met with in Scotland, and in England 

 it appears to be rare. 



C. Abdomen luteous; wings nearly smok}' throaighout; feet yellow 

 luteous; body not depressed. 



Antennae 10-12 jointed, not pale at the base; pronotum and tegulae 

 black — vaga n s . 



Antennae 14-15 jointed, pale at tlie base; pronotum and tegulae pale — 

 microccjphala. 



Phyllotoma vagans.

Antennae about the length of the abdomen, 10-12 jointed,
