Holotypc : $ Au_trti.st 3, (irand View, Grand Canyon, Arizona 

 (H. H. Knight) ; Cornell University collection. 



This very distinct and interesting species is rej^resented only by 

 the type specimen which was swept from the clitt rose (Cowania mex- 

 icana). The failure to secure additional specimens indicates that its 

 presence on that plant may have been accidental. 



Deraeocoris rubroclarus new species 



Elongate, calli and [jronotum reddish brown to ferruginous, scutellum pale; 

 hemelvtra vellowish translucid, immaculate, cuneus reddish translucent.
