This species I only previously knew from Central America. 

 The (J cneva Museum possesses a series of specimens taken 

 at Dallas, Texas. Some of these agree with the typical 

 form, others have the spots to the raesonotum nearly con- 

 fluent, thus giving it an almost black appearance. Others, 

 apparently bleached specimens, have nearly all the macular 

 markings obliterated, including those on the tegmina.
