 ovipositor is sword-shaped. 



In those species of this family in which the wings are 

 well developed we find the males provided with an elabo-

 mates. This consists of a peculiar arrangement of the veins 

 and cells of a portion of each wing-cover near its base. This 

 arrangement differs in the different species ; but in each it is
