Two years ago, Mr. Greene and I were searching for larvae 

 of E. tripunctata in Derbyshire, when I stumbled upon 

 two larvae which I at once saw were those of no British 

 Eupithecia I bad ever yet seen, their black heads giving 

 them a most distinct appearance. Mr. Greene was afterwards 

 fortunate enough to meet with more, and from them we bred 

 what turned out to be E. trisignatcij H.-S. 



The larva feeds in September on flowers and seeds of An- 

 gelica sylvestr is, in company with and in similar situations to 

 E. tripunctata. Mr. Greene and I have only met with it
