346 PROCEEDINGS OF THE NATIONAL MUSEUM vol. 88 



Male: 4-4.5 mm. Antennal scape (fig. 9, p) exceeding level of 

 posterior ocelli; metafemur with inner tooth blmit; petiole slightly 

 longer than metacoxa, and only slightly enlarged at apex; gaster 

 equal to or shorter than metafemur. 



Type locality. — Indiana. 



Type. — Neotype, female, Delaware, in Academy of Natural Sciences 

 of Philadelphia, E. T. Cresson determination. 



The identity of this species has become somewhat confused. Say's 

 type has long since been lost, but Cresson redescribed it in 1872, and 

 as his material is still available I have considered it as fixing the iden- 

 tity of this species. The original description mentions only one struc- 

 tural character, the presence of minute teeth on the propodeum, and 

 this character is present in specimens determined as this species by 

 Oresson. These propodeal teeth are wanting in the specimens deter- 

 mined as this species by Howard and others. Most of the American 

 references to this species are now applied to C eratosmicTa nieteori., de- 

 scribed below. 



Types for synonj^ms : longipetiola Ashmead, 41182, U. S. National 

 Museum ; kahlii Ashmead, 8073, U. S. National Museum. 



The types of S. longipetiola Ashmead and M. hahlii Ashmead differ 

 neither in color nor in structure from the specimens determined as S. 

 debilis (Say) by E. T. Cresson. 



Host. — Unknown. 



Distribution. — Delaware, Florida, Illinois, Iowa, Kansas, Louisiana, 

 Michigan, Minnesota, New York, Pennsylvania, Rhode Island, Texas.

This species resembles C. immaculafa (Cresson) in lacking lateral 

 propodeal projections, having fairly slender metafemora (fig. 12, o) , 

 and having the petiole approximately 10 times as long as wide at the 

 widest point ; it differs m having the petiole expanded in the middle 

 (fig. 13, A), and the male antennal scape broad from the base to the 

 apex (fig. 9, q), rather than broad only at the apex (fig. 9, .5).
