Described from numerous specimens reared from rose seeds 

 at Ithaca, N. Y. In Bull. 265, Cornell Exp. Sta. I have con- 

 fused this species with M. nigrovariegatiis . All the other 

 localities there given refer to that species. Figures 82 and 83 

 are also of nigrovariegatiis . In the collection of the U. S. 

 National Museum there is a series of specimens reared from 

 rose seeds imported from Peking, China. I have also reared 

 several specimens from rose hips from Heilbronn, Germany, 

 procured for me by Mr. Carl Ilg from his friend, Mr. Gustav 

 Wieland.

 the pin on which the type was originally tag-mounted. Only 

 the hind legs and one front wing remain. The stigmal club 

 is large, very dark colored and appears to be surrounded by 

 a narrow clearly defined cloud. 



In 1888 (Bull. 3, Kansas Agriciiltural Experiment Station, p. Ill) 

 Ashmead described another species under the same name, Megastigmus 

 flavipes. Through the kindness of Professors T. J. Headlee and G. A.
