half, the apical half equal and sym- 

 metrical, bluntly rounded (rarely trun- 

 cate or angulate) apically. 

 f. Interspace between mesosternal lobes 

 of male distinctly longer, generally 

 much longer than broad, and much 

 narrower than the lobes; metas- 

 ternal lobes attingent or sub-at- 

 tingent in the male, 

 g. Sub-genital plate of male broad, 

 at least as broad as long; cerci 

 ^ incurved feebly and gently, or 

 not at all Bawsoni. 



gg. Sub-genital plate of male rather 

 narrow, narrower than long, 

 although short ; cerci abruptly 

 incurved apically Gladstoni. 



ff. Interspace between mesosternal lobes 

 of male quadrate, almost or a little 

 transverse and but little narrower 

 than the lobes ; metasternal lobes of 

 male only approximate borealis. 



ee. Sub-genital plate of male conspicuously 

 narrower at apex than at base (gener- 

 ally only hall as wide), rarely at aU 

 elevated at apex above the lateral mar- 

 gins and never notched ; cerci always 

 distinctly narrowing on basal half, the 

 upper angle of the apex prolonged and 

 oiter sub-acuminate femur-rubrum. 



cc. Cerci of male more or less expanded apically, so 

 as to be broader at some point beyond the
