1 he insect here figured resembles not a little L. 4-macu- 
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 1 804 in a wood 
at Sprowston near that city.
