Habitat : On the roots and underground stems of Mentha 

 aquatica, The Lake, Ke w, 13.10.06. Collected by Mr. G. Nicholson, 

 to whom I am much indebted for a liberal supply of specimens. 



The young females and larvae resemble the adults in colour ; 

 but the immature females are generally covered with a long white 

 flocculent secretion. 



The characters herein described agree, on the whole, with 

 Passerini's description of Rhizobius menthae, but I do not find the 

 marked variation in the antennal formula which is said by the 

 author to exist in this insect. It is just possible therefore that the 

 examples from Kew may hereafter prove a distinct species ; but 

 we know so little of the structural characters of the British 

 Aphides that I do not deem it desirable to add to the confusion 

 that already exists by erecting a new name for this addition to the 

 fauna of the British Isles.

This second supplementary list of the scale insects includes but 

 a single specks (Pulvinaria vitis, var. euonymi) that is new to the 

 &ew *auna ; but the food-plants of the remaining species are all 

 new. as stated in the previous list these are important from an 

 economic standpoint, and should be placed on record.
