MACROPHYA ALBICINCTA. 131 



egg is bean-shaped, pearly white, rather flat on one 

 side, the skin being very thin. 



The larva has a sordid greenish-yellow head, with 

 a quadrate, shining black spot on the vertex, and two 

 large round similar spots on the sides, in which the 

 eyes are placed, mouth brownish; head both above 

 and below shortly and sparsely hirsute. In the 

 younger larvae the body is a sordid yellow, with three 

 brown-green stripes, the outer of which are darker 

 than the inner one ; the spiracles pale yellow ; above 

 them are some black lines, and below, just over the 

 legs, is a dark transverse line. Above the anus is a 

 small black spot. The three dorsal lines have the 

 appearance of being ribbed, the inner side of tho 

 numerous folds of the skin being of a pale tint. The 

 thoracic legs are pale yellow, with black lines on the 

 first or thickest joint. The claws are pale brown. 

 The ventral surface, as also the posterior legs, are pale, 

 without spots, and the caudal end is beset with short 

 white hairs. 



When full fed there are two dark grey triangular 

 marks over each leg. The black spots over the spiracles 

 become larger, and the edges of the stigmata very pale 

 brown. Over each proleg are two oblique blackish 

 spots, and there is a triangular spot over the anus of 

 the same colour. 



After the last moult the head is reddish and the 

 body entirely of a very pale greenish-grey colour ; the 

 three dorsal lines being darker than the ground colour. 

 The black points on the sides disappear. 



During the day the larvae remain reposing on the 

 underside of the leaves. In the evening they commence 

 to feed, eating large holes in the leaves; they do 

 not invariably commence to feed along the margin, but 

 frequently eat holes out of the middle. 



The larvae are found in June and July, and spin their 

 cocoons in the earth, emerging from them in the winged 

 state in the following spring. 



In Britain, allncinda is perhaps the commonest and
