Art. X.] Hine, Panorpidae of America North of Mexico. 263 
genus Nemoptera which at the present time is not considered in 
Panorpidae. It may be mentioned that two arguments which 
Dr. Fitch produced against placing it in the Panorpidae do not 
seem so strong since we know more of the family. First, the 
short beak found in Merope, is approached by Panorpodes, an 
insect which is near enough to Pano^pa to have the abdomen 
ended by a cheliferous segment. Second, Merope was taken in 
the evening at light ; at least one species of Battacus has been 
taken at light several times. 
Merope tuber Newman.
