 S ?. Tongue short ; pilit'er with bristles. Palpus small, rough with long scales 

 and hairs, much smaller in ? than in S ; joint not open. Antenna : J, compressed, 

 laterally impressed, fasciculated ciliae of both the proximal and apical series long, 

 dorsal edge of groove projecting, outline of antenna undulate in dorsal view ; 

 ? , proximal segments slightly depressed, traussection transversely oval, middle 

 segments slightly compressed, not grooved, feebly constricted at the joints, seriated 

 ciliae not distinctly prolonged, subdorsal ones somewhat longer than the others.
