LIFE HISTORY. The EGG is laid on various 

 grasses in July, and the young CATERPILLAR 

 probably hybernates when small; it has been 

 found full grown and feeding on grass in the 

 following June, when it is somewhat shuttle- 

 shaped, gradually tapering, especially towards 

 the posterior extremity ; the head is of the 

 same width as the second segment ; the head 

 and body are green, the latter having six 

 slender white stripes : it spins a silken cocoon 

 among the blades of grass, and therein turns 

 to a green CHRYSALIS, which has a pointed 

 head-case, and is very sharply tapered towards 



the tail. It remains but a short time in the 

 chrysalis state. 



TIME OF APPEARANCE. July. 



LOCALITIES. Mr. Birchall took Hesperia 

 Linea in Ireland at Powerscourt and near 

 Cork, but did not observe it in the Isle of 

 Man ; and I have no record of its having been 

 taken in Scotland. In England it is generally 

 abundant, more particularly in the southern 

 and mil Hand counties, but has mysteriously 

 disappeared from many places where it was 

 formerly common ; in Essex it occurs in open 

 swampy places that are covered with rushes.

 to the arrangement of the sexes I have adopted in other instances.
