 hexagonal, longer than wide, lateral areae sometimes divided, some- 

 times not so ; the petiole as long or a little longer than the post-

 and varies in shape ; 2nd segment about one-third longer than

? Var. One male. Antennae darker ; apex of 2nd, 3rd, and 4th 

 segments of abdomen reddish. 



Male and female ; length, 4-5-5 mm. 



Bred by Mr. J. E. Fletcher from Elachista cerussella. 

 The ? var. I took at Brundall, near Norwich. This 

 insect comes very near L. longipes, but the antennae . is 

 differently coloured, as are the coxse and trochanters ; 

 the insect is also much smaller, and the head is not so 

 large. I believe it is a good species.
