34 EREB1A CASSIOPE. 



at the top, rather larger towards the base, which is 

 also rounded off and a little depressed in the centre ; 

 it is ribbed. All were laid in a vertical position ad- 

 hering by the biggest end. When first laid and for a 

 day after it is a bright canary yellow, and in two days 

 it changes to a slight tint of pale olive-greenish, but it 

 is still very shining. 



On the fourth day (July 5th) the eggs were spotted 

 over with a faint brown at regular intervals, the next 

 day they were of a pale brownish tint, spotted with 

 deeper brown. By the 13th they had become of a 

 pinkish drab colour, with the upper end or top of the 

 egg darker than the rest. On the 14th their colour 

 had assumed a dirty tinge and their hatching seemed 

 imminent, and by the evening I found that three 

 young larvae were already disclosed, and other five were 

 hatched by the following morning. 



The newly hatched larvae were flesh-coloured, with 

 ochreous flesh-coloured heads, a faint purplish-grey 

 tinge showing through the skin of their bodies. The 

 larvae ate away the tops of their egg-shells, indeed two 

 or three of them ate about two-thirds of the egg-shells, 

 which were quite white and very clear and thin. 



The young larvae were at first offered Festuca ovina, 

 Aim flexuosa, and Poa annua; this last bore slight 

 evidence of having been a little eaten, though they 

 were generally to be seen on the Aira flexuosa. On 

 the second day one was found to be dead. 



Shortly afterwards I put them on some Nardus 

 stricta covered with grenadine, but they all escaped 

 through the meshes, having a fancy to feed on the 

 summits of the grass leaves, which protruded through 

 the grenadine. (W. B., Note Book II, 80.) 



The pupa of Cassiope is little more than three-eighths 

 of an inch in length, rather thick in proportion, being 

 less dumpy in form than Hyperanthus, but more so 

 than Blandina. The colour of the back of the thorax 

 and wing-cases is a light green, rather glaucous ; the 

 abdomen a pale drab or dirty whitish ; a dark brown
