Z EMMELES1A AFFINITATA. 



The first moth was bred on the 14th of July, the 

 last on the 4th of August, 1879, both females, and at 

 an earlier date many chalcids emerged. 



The egg in shape is a broad oval, its surface ribbed 

 and pitted. When first laid the colour is pale straw- 

 yellow ; on the fifth day it begins to look a little dirty, 

 and it hatches on the sixth. 



The young larva is whitish, with black head and a 

 blackish plate on the second segment ; after a moult 

 it becomes of a faint drab tint on the body ; after the 

 second moult it assumes a deeper tint of drab and has 

 a darker dorsal line, with the belly whitish, the head, 

 the plate in front and plate behind, brownish-black. 

 As it advances in growth it becomes more or less 

 tinged with pinkish on the upper surface, showing 

 decided lines, and of a pearly whiteness below. 



The full-grown larva, with reference to the size of 

 the perfect insect, is, like some others of this genus, 

 very small, not more than about from three-eighths to 

 half an inch in length, and from the form and re- 

 stricted size of its dwelling within the seed-capsule, 

 its natural hunch-backed looping posture tends appa- 

 rently to dwarf its actual dimension ; its figure is 

 dumpy for a geometer, of about equal substance as 

 far as the tenth segment, from whence it tapers a little 

 to the anal extremity ; the head is a little less than the 

 second segment, though of a broadish character ; the 

 segments of the body are well divided and very plump, 

 yet each having two or three wrinkles across the 

 back ; the spiracular region is rather tumid ; in colour 

 the head is black or blackish-brown and glossy, the 

 lobes on the crown well defined by the margin of pale 

 skin from the blackish -brown shining plate on the 

 second segment ; another plate, less dark, occurs on 

 the anal flap, and there are two remarkable additional 

 horny plates situated one on the outer side of each 

 anal leg ; the rest of the body is without gloss, and 

 of a light drab colour broadly tinged with pink down 

 the back and sides, becoming a little paler on the
