 {ParJciiisonia ?nicroj)hylla) , palo-verde (Cercidium torreyanum),

Casey (1898) described orevieollis from four specimens and 

 grandicollis from a single male, all from the same locality, Lesne 

 (1937) placed brevicoUis as a synonym of simplex Horn in his sub- 

 genus Sch istoceros. After studying the type of grandicollis the writer 

 is unable to separate it from simplex.
