 convex and thickened, abruptly flatly emarginate at the junction of 

 its lower and middle thirds ; middle third faintly convex, with four 

 or five minute tooth-like processes (as in some species of Ni[cti- 

 nomus) ; upper third straight ; outer side deeply and flatly emargi- 

 nate for half its length beneath the tip, the emargination termi-
