ANTHROCERA. 87 



found attached to blades of grass. We have six species in 

 Britain : one with the fore-wings streaked with red ; four with 

 five red spots on the fore-wings ; and one with six spots. 

 Varieties are sometimes met with or bred, in which the red 

 spots are replaced with yellow. In some of the European 

 species the red spots are surrounded with white or yellow 

 rings.
