1 HE insect here figured resembles not a little L. 4'7naai- 

 lata; but is nevertheless quite distinct from it. The head 

 is of a dirty yellow. Trunk downy, of the same colour, with 

 black sutures. Abdomen prismatical, dirty yellow, with 

 the lateral and dorsal angles black. The wings, a little 

 within the anterior margin, are stained with a longitudinal 

 yellow stripe, which does not quite reach the tips. The 

 anastomosis is black, with a brown cloud terminating the 

 wing. The secondary wings have besides a black spot at 

 their base. 



We are indebted to Mr. Joseph Hooker of Norwich for 

 this insect, who took it in the summer of 1804 in a wood 

 at Sprowston near that oily.
