 tiie orifice preceded by a transverse ridge, forming the lower or anterior lip of the 

 cavity, this ridge mesially indented. 



The harpe of the hybrids ocellata x populi is often sinuate ventrally before the 

 apex ; this sinus corresponds to the deep apical sinus of pojjuU, dividing the harpe 

 of this species into two lobes ; the narrowed apical jiortion of the 06'('//«/«-iiarpe is, 

 therefore, homologous to the upper lobe of the harpe oi populi
