 with white pile. Abdomen with spots of light golden pile on the sides of the second, third, and fourth 

 segments, the pile extending over the larger part of the fourth and fifth segments. Legs black, with 

 white pile ; first two joints of the anterior tarsi, and most of the third joint also of the hind tarsi, light 

 yellow. "Wings broadly brownish distally.

Hab. Mexico, Xucumanatlan in Guerrero, Cuernavaca in Morelos (H. H. Smith), 

 Jalisco, Atoyac in Vera Cruz [Schumann). 



Four specimens. This species differs from C. lasiophthalma in the narrower front, 

 the more prominent lateral tubercle, the more obtuse third joint of the antennae, the 

 broad light golden covering of the posterior part of the abdomen, and the wholly 

 black femora.

A single specimen from Jalisco, Mexico, agreeing well with the description of 

 0. trivittata 2 , save that the black of the abdomen is broader. Bellardi's description of 

 the abdomen is indefinite, yet I believe that Johnson is right in the above synonymy.

Hab. Mexico 1_5 , Morelia in Michoacan (Hoge), Orizaba, Toluca (Saussure 2 ). 



A single male specimen from Morelia, differing from Macquart's description 1 in 

 lacking the spot on the base of the third abdominal segment, and in having the hind 

 femora wholly yellow ; the front and middle femora have the upperside distally 

 black, but the black is not extensive. The post-alar callosities are yellow. Bellardi 2 

 says that the spots on the sides of the abdomen may be two, four, or six in number, or 

 may be wholly wanting. From S. euchlora, Gerst., it differs only in the presence of 

 the small femoral spots, evidently a variable character. 0. prasina, Jaenn., has redder 

 pile on the mesonotum. 0. lefebvrei was not identified by Osten Sacken in the earlier
