The writer found the types and a large series of specimens hiber- 

 nating under the bark of a log where the insects had collected to spend 

 the winter. When found, some were stiff with frost but soon revived 

 as they were warmed in the sunshine. The writer has taken two speci- 

 mens late in the fall as they came into buildings evidently seeking hi- 

 bernation quarters. The species breeds on Pitius strobns and Pinus 

 resinosa but only in favored spots on certain trees. One specimen 

 was taken on larch. Larix laricina, but its occurrence on that tree may 

 be merely accidental. The small white, wax-coated nymphs, were found 

 in company with Chcrmcs pinicorticis Fitch, resembling very much the 

 wax-covered aphids. The bug is probably predaceous to a certain 

 extent upon the pine bark aphid altho actual puncturing of an aphid 

 was not observed. 



Deraeocoris (Camptobrochis) nubilus obscuripes new variety 



Structurally very similar if not identical with nubilus, but much darker 

 in color, especially the legs.

 line of front and the jugae brownish, spot each side of vertex and more 

 broadly along the carina pale. 



Antennae: black, structurally not distinguishable from the typical form. 



Pronotum: median line of disk reduced to a slender brownish line, lateral 

 margins rather broadly brownish testaceous. SeuicUum ivory-white at apex and 

 basal angles. 



Hcmclytra: piceous, base of embolium and corium, central area of clavus, 

 and base of cuneus, brownish testaceous. 



Legs: black, hind femora with an obscure reddish black dorsal mark just 

 before and at apex; tibiae with two obscure reddish brown annulations. 



Holotypc: 2 June 30. Bozeman, Montana; author's collection.
