Variation. — Mecidea major shows considerable variation in size and 

 structure. The second antennal segment of both sexes varies con- 

 siderably and in the case of females often renders this structure of 

 Httle value in separating major from minor. The juga show such a 

 degree of variation as to make them of little diagnostic value. In the 

 specimens examined the greater number show the juga to be barely 

 contiguous in front of tylus, mth the inner margins divergent toward 

 apices and usually tipped slightly inwardly and downward along apical 

 half; however, many specimens present the almost continuously 

 contiguous, acuminate form characteristic of minor as well as the other 

 extreme in which the juga are not contiguous but continue parallel 

 with each other for some distance before the tylus. The genital 

 plates of the female also show considerable variation, making them 

 difficult to use for diagnostic purposes; characteristically all plates 

 tend to be shorter in relation to their length than is typical for minor.
