HoLOTYPE. — Male, Evergreen, Colo., collector not known. Col- 

 lected on Pinus ponderosa. Bears a label: "Aradus n.sp. near 

 marginatus Uhl. det H. G. Barber" (USNM type 67582).

This species is dedicated to the memory of the late Mr. H. G. 

 Barber, an eminent American hemipterologist, who first identified it 

 as a new species. 



Aradus barberi, new species, runs in Parshley's key to A. marginatus 

 Uhler, as Barber has indicated. It differs by having antennal seg- 

 ment II one and one-half times as long as the distance between eyes, 

 while in A. marginatus these two measurements are equal.
