Downes writes concerning his specimen : "The nymphs feed 

 on a yellow fungus of puff-ball type, growing on the bark of 

 dead fir stumps. Adult was raised from last stage nymph 

 taken in May. This nymph was kept alive in a vial without 

 food for three months, but was supplied with a piece of rotten 

 wood and slight moisture, and moulted to adult on August 

 6th.'' This note is of especial interest since there seem to be 

 on record no definite statements concerning the food of Arad- 

 iis. I would suggest that in all probability the nymph found 

 suitable fungous food in the rotten wood supplied. With my 

 friend de la Torre Bueno I very recently made an observation 

 bearing on the matter. In this case we watched a captive 

 adult of Aradus quadrilineatus with its rostrum inserted in the 

 spongy and fungus filled substance of a piece of damp rotten 

 bark, undoubtedly drawing up the juices present.
