river valleys and other topographic features. If only the northern 

 series of records were taken into consideration, it might be thought 

 to follow the principal railwa}^ lines of this portion of the state, but, 

 moreover, several important railways pass thru counties that are 

 not included among these records. It seems that the advance and 

 dissemination of the species is due mainly to natural flight and its 

 progress eastward may be expected to follow this method. It will 

 be interesting to watch for the eastward extension of its present 

 margin of distribution. During the summer of 1914, no records 

 for the species were made in the state ; if the insect is present during 

 the coming summer, we will be glad to receive such records.
