96 AMERICAN HYMENOPTERA. 



Redescribed from 9 type, three 9 paratypes and four 

 specimens. 



Type. — 9 . No. 80, Mexico, American Entomological So- 

 ciety (Academy of Natural Sciences, Philadelphia). 



Paratypes. — Three 9 's. No. 80, Mexico, American Ento- 

 mological Society (Academy of Natural Sciences, Phila- 

 delphia). 



A distinct species, easily recognized by the ferruginous 

 color of the body, the others being black. 



In 1890 Ashmead described Nototrachys annuiicornis, plac- 

 ing it temporarily in the Genus Nototrachys, but practically 

 saying that he did not know where it belonged. Comparison 

 of his type with the type of ferrugineus Cress, shows that 

 they are synonymous. The small third tibial spur which 

 Dr. Ashmead mentions seems to be absent. Dr. Ashmead 

 later recognized that his species belonged in this genus, as 

 his labels show, but failed to identify it with ferrugineus 

 Cress. 



Distribution. — Illinois ; Texas ; Orizaba, Mexico. 



The type of this species came from Mexico ; there are four 

 specimens in the U. S. National Museum from Texas. Cam- 

 eron reports it from Orizaba, Mexico (19°). So far as known 

 it comes from the Upper and Lower Austral zones. It prob- 

 ably ranges south into Central America, but as there are no 

 records of its capture there the exact range can not be deter- 

 mined. 



I can find no reference relative to life history, habits or 

 hosts. The specimens in the U. S. National Museum were 

 taken December 26 in Texas.
