Remarks: In Illinois, Kansas, Nebraska, and Missouri occur speci- 

 mens with the pronotum entirely pale. However in a series of four 

 specimens from Crevecoeur Lake, St, Louis County, Mo., all collected 

 June 7, two specimens have the pronotum entirely pale, two are typ- 

 ically dark marked. In a series of seven from Onaga, Kansas, five 

 have entirely pale pronotum, two are dark marked. Similarly, in a 

 series from southern IlUnois, while the majority are with an entirely 

 pale pronotum, a few have typically dark-marked pronotum. Hence 

 this pale coloration would seem merely a color phase.
