 ately long mucrones.

 labeled Marquette, Mich,, are in the J. L. LeConte Collection (MCZ

I hereby designate as the lectotype of A. vicinum Smith the female 

 specimen (USNM 1255) labeled Garland, Colo. Cotypes with the 

 same data are in the J. L. LeConte Collection (MCZ 370). 



Material examined: Lectotypes of A. walshii and A. vicinum, 

 specimens of A. simile from Europe determined by Hans Wagner m 

 the Bovie Collection of the U. S. National Museum, and 150 speci- 

 mens from the United States and Canada. 



Biology: Apion lanuginosum Walsh was described from material 

 taken from galls made by a Cecidomya sp. on Salix strohiloides. Do- 

 nisthorpe (1938) records A. simile from Windsor Forest, England, 

 by sweeping and under faggots in a willow swamp. Fall (1898) 

 states that in New England A. walshii occurs abundantly on white 

 birch, Betula alba. Hustache (1931) records A. simile as occuiring 

 on Betula alba, stating that the species is common in France, I have 

 taken a large series from birch leaves in New Hampshire. Wahlgren 

 (1951) cites A. simile as a gall maker on Betula verrucosa. Wolcott 

 and Montgomer}' (1933) took A. walshii by sweeping in the maple 

 zone of a Tamarack swamp in Porter Co., Ind.
