Mr. Bridwell also sent an example of CnlliojMi* rcrbcnce Ckll. 

 and Porter, iiied., collected at Baldwin, Kansas, in July. This 

 species, the type locality of which is Las Vegas, N. M., is 

 allied to C. atnli-cniforniis, but differs in the face-marks (9) as 

 follows: Clypeus strongly but not closely punctured, shining, 

 black, with the anterior margin broadly white; no supra- 

 clypeal mark ; lateral white marks triangular, with the inner 

 angle cut off, the upper angle not reaching the level of the 

 antennae; labrum with a transverse light mark.
