 noticeably dimori)hic in wing-length."' He gives the following 

 measurements; 



Total length, short-winged, f, i i mm., 5, 14-16 mm.; long-

 winged, f, 10.3-10.4 mm., 5, 13. 2-14 mm.; long-winged, t, 

 10. 5-12 mm., 5, 15-16. 2 mm.; post, fem., t, 5.6-7.3 mm., 

 $, 7.8-9 mm.; antenna;, /, 4 mm., j, 4.5 mm. 



For convenience the short-wing form may be known as
