Type and allotype Cat. No. 18237 U. S. N. M. Paratypes in 

 the author's collection. 



Described from four specimens, two females and two males, 

 received from D. K. McMillan with the following note, "Col- 

 lected May 22, 1909, on the blossoms of Cissus incisa, rather com- 

 mon and a number of mating pairs were crawling among the 

 foliage." 



This species is allied to C. plicatum Lee. but is distinguished 

 from that and the other species found in the United States by 

 having dull greenish-blue elytra and all of the femora black. 

 Named for E. A. Schwarz. 



The following table will assist in the identification of the species 

 found north of Mexico.
