spicuous black and yellow bodies. A single sweep with an insect net 

 captured some sixty or more specimens while a cloud of others flew 

 away on being disturbed. I have also noticed similar groups of 

 Myzine resting in the daytime in Massachusetts, but never so large a 

 number on a single plant. An explanation for the gregarious habits 

 of the male Mvziiie can readily be made when it is recalled that as the 

 males seem to be more numerous than the females, the greater propor- 

 tion of the males probably never take any active part in the economy 

 of the species.
