sensoria upon Segment III, and these are oval or sometimes al- 

 most subcircular like those upon Segment III of the American 

 fall migrant. 



Another thing which should be mentioned is the absence of

the large quadrate patch on the abdomen of the spring migrant 

 of the American form. In his description of the spring mi- 

 grant of corni Koch (1857) does not mention this marking 

 and his figure does not show it. The writer supposes, there- 

 fore, that it is absent from the spring migrant of corni also. 



The writer has never seen European spring migrants and is 

 therefore unable to give the number of sensoria. Judging 

 from the American species and from the early summer form 

 of corni he would suppose that it possessed about six or seven 

 somewhat oval sensoria upon Segment III and in this way dif- 

 fers from the American form which possesses few sensoria.
