tibiic have alwvc the basal outer tootli only three serrations, the

 truncate cone, not emarginate in the middle at tip and densely 

 bristly ; ligula long, very broad and very deeply incised, but not 

 quite bi-lobate ; second joint of labial palpi swollen and as long as- 

 the apical one which is narrower and much more cylindrical, pal-

 apical lobe long, closely ciliate, inner lobe briefly ciHate and having 

 at the tip a strong, hooked tooth, apical joint of maxillary palpi

 at tip ; eyes not divided by the canthus of the gense, and showing as 

 much on the upper side as they do on the under side : labrum 

 narrow, transverse, not covering the mandibles which are com-

 very long outer teeth and very closely serrate above the digits, apical 

 spur a little longer than the apical outer tooth, curving outwardly in 

 the same direction, but much narrower ; intermediate tibiae strongly 

 emarginate in the upper part and sharply dilated at tip, bi-carinate 

 and bi-dentate above the median part, and having two long, flattened 

 apical spurs which are not of equal length and are densely fringed
