BRACHYCOLUS STELLARI^. 147 



joints globose ; tliird, fourth, fifth, and sixth nearly 

 equal ; seventh slightly ringed and about as long as 

 the fifth and sixth taken together. 



Body very long and narrow, mealy. 



Nectaries very small and inconspicuous. 



Cauda moderately long, pointed. 



Legs very short, the hind pair scarcely projecting 

 beyond the apex of the abdomen. Tarsi rather long. 



Rostrum very short, hardly reaching to the second 

 coxa. 



The shortness of the limbs separates this genus from 

 HyalojJ terns, and the length of the tail from Cryi:>to- 

 siphum. The linear character of the body is unusual. 

 The winged form has not been observed, but, as this 

 Aphis lives on the tufted summits of plants, it is very 

 probable that such exists.

 This curious Aphis some years ago was described in 

 the ' North British Agriculturalist,' ii, p. 1SS, by Mr. 

 James Hardy, under the name of Apliis stellarice, and
