Mâle. 



The mandibîes (fig. 28) hâve not been studied by 0. under 

 sufficient amplifications, so as to enable him to discern every 

 détail. Thus, his dramng is imperfect (1903, pi. 10, fig. 13, 14). 

 We notice that the lower jaw is longer than the upper one, 

 with a very large perpendicular terminal tooth ; along the side 

 of the jaw there is a narrow, thin and falciform apendage, 

 curving slightly upwards near the top, and exceeding the jaw 

 by nearly one third of its own length. It is fused with the 

 jaw in the basai third. Lower jaw thin, blade-like, slightly 

 constricted at the base, rounded at the top, and with a low, 

 rounded subterminal tooth, on a level with which the small 

 pilus dentarius is inserted. The flagellum consists of only 

 3 to 4 small slips.
