there is no doubt, for they can be seen to move back- 

 wards and forwards together, always keeping the same 

 relative positions. The movement is a fairly brisk one, 

 reminding one of a shrug of the shoulders. It can be 

 induced by breathing upon the egg, or by giving a 

 tap to the support on which it rests, but it occurs from 

 time to time even when the egg is unmolested. Many 

 other (perhaps all) Erebim ova develop these pinkish 

 blotches after a few days. I have seen something similar 

 in Coznonympha. The base of the egg is covered with 

 large shallow cells of irregular shape. Before hatching the 

 colour darkens to dull fleshy grey, there being darker and 

 lighter patches. The groups of specks disappear when 

 this change takes place, and the shape and markings of 

 the larva are seen through the shell. The head occupies 

 all the upper part of the egg, while the body is curled 

 round horizontally with the extremity turned downwards. 

 The numerous pits on the head show through as brown 

 dots. The two groups of beads (ocelli ? one on each side) 

 are very clear, so is the mouth and the arch above it. 

 The markings of the body (lines and tubercles) are quite 

 distinct. The larvae commenced to hatch out on July 

 23rd, and all were out by the evening of July 24th. 

 They eat away the top of the egg in a circle, emerge 

 through the hole made, and eat up the rest of the egg or 

 part of it. 



" The newly-hatched larva is 28* mm. long when still, but can reach 

 3 mm. when walking. Width of the head - 7 mm. It is a large 

 head, and is higher and broader than the body, which tapers to begin 

 with, down to the forks. The colour is that of most newly-hatched 

 Satyrids, a sort of pale straw. The shape and markings of the 

 head are typically Satyrid. It is rounded, rather flattened in front ; 

 much resembles a lemon rind in pitting and polish. The pits are 

 large. Depression between the lobes very shallow. The side 

 ' beads ' (ocelli 1) are large, dark brown, and shiny. The usual 

 small, brown seta patches are very distinct. Setae short, transparent, 

 curved forward. Those just over the mouth are longest. 



" The 1st division of the 1st thoracic segment has 16 small beady- 

 brown tubercles arranged transversely but not in an exact line. The 

 2nd and 3rd thoracic segments have both a dorsal dark-brown 

 tubercle-bead outside the dorsal stripe. In a line with it on the 

 sub-dorsal stripe they have another bead. The abdominal segments 

 have the first bead on, the 1st sub-division, and in a line with those
