This striking form appears to be rather common though nothing 

 is known concerning its life history. It was first taken on an office 

 window at Albany, N. Y., June 8, 1906 and was obtained several 

 times under similar conditions a year later. Specimens of apparently 

 the same form were taken July 17th at Kaslo, B. C, by A. N. 

 Caudell.
