Metopius pulchellus Cresson, 1865, Proc. Ent. Soc. Philadelphia, vol. 4, p. 271; 

 ?. Type: 9 , Colorado (Philadelphia).

 color is ferruginous rather than black. Black occurs only on the 

 occiput (sometimes), as a median anterior spot on mesoscutum, on 

 base of third and following tergites, and as mfuscation on upper hind 

 part of mesopleurum, in sternaulus, and in areas near the scutellum.
