GENERIC CHARACTER. 
Antenne with an abrupt, somewhat ovate club. 
Palpi prominent, triarticulated, somewhat conic, the 
second joint largest, the third somewhat naked. 
Feet in both sexes six, formed for walking ; tarsi with 
minute nails ; hinder ¢zbie with two spurs. 
Wings erect; hinder ones receiving the abdomen in a 
channel; entire in some, tailed or notched in others. 
The flight of the Zycene is very rapid. The European 
species inhabit the borders of the woods, fields, and heaths, 
‘and the sexes generally differ from each other in colour. 
The antenne of all the species that I have examined, 
were black annulated with white.
