 n:argin slightly notched allowing the tooth-like angle of the coxa 

 to appear. Little is to be seen of the pleurae from below ; their 

 inner margin is almost parallel (Fig. 13). Femora and claw 

 armed, the former with two chitinized tubercles along the inner 

 edge, the latter with a short but strong basal tooth ; it is worth 



mentioning that the trace of suture 

 between femora and trochanter passes 

 above the first tooth in order that the 

 latter has to be con- 

 sidered as belonging to 

 the trochanter.

 described for G. corrdlinus as a " zugenformiger happen"; it is 

 scarcely developed with the present species (Fig. 15).
