This rare moth, which has never been figured in any British 

 work, has been taken near Birmingham and Bristol, I believe 

 in May: in France it appears in April. Godart says the 

 caterpillar is green, with a yellow head and two longitudinal 

 white lines on each side of the body, and that it is found in 

 September and October on the Poplar. I am indebted to 

 Mr. Dale for the loan of the female figured ; and Mr. Hope 

 informs me that he bred a very fine specimen last spring.

 As the larvae of this last division are different from the others 

 in form, and enter the earth to change to puptc, it may be 

 hereafter found necessary to give this group the generic name 

 of Cymatoj)hora.
