226 LLOYD'S NATURAL HISTORY. 



It is snow-white, with a fine brown line near the base on the 

 fore-wings, dotted on the nervures, and followed by a zig-zag 

 shade. Next comes a broad band of white, and beyond this 

 a zig-zag curved line, varied with light brown and bluish-grey 

 spots, and intersected by a sinuated white line. The hind- 

 wings have a black central lunule, and the sub-marginal 

 markings are continued on them. The fringes are chequered 

 with brown and white. 



The Lace Border. 



The larva lives on mint and wild thyme. It is brownish 

 ochreous, with a fine light grey dorsal line, interrupted on each 

 segment from the fifth to the ninth by an X-shaped mark. 

 There is a dark brown sub-dorsal line, and a pale ochreous 

 spiracular line, bordered below with dusky. 



The moth appears in May and June, and again in August. 

 It is a local insect on the chalk in the South of England. 



FAMILY MICRONIID^E. 



This family is entirely exotic, and includes a number of 

 moderate-sized species, with short antennae, sometimes pecti- 

 nated in the males, slender palpi, a short abdomen, and short 

 stout legs. The wings are broad, and generally white, flecked 

 with grey, and marked with oblique or transverse darker lines. 

 The cells are very short. The fore-wings are usually pointed, 

 and the hind-wings angulated, often with black spots before 

 the angle.
