32. ATHERMANTUS. 



Characters of Hylotoma, but with the tibiae rather flattened and 

 clothed with short bristles ; two end spurs, but none in the middle. 

 Third joint of the antennas rather short and thick, flattened towards 

 the extremity. The antennas will probably prove to be longer, cili- 

 ated, but not furcate, in the males. 



In the type the first discoidal cell on the left side is divided by 

 an additional nervule, thus making three recurrent nervures on one 

 side ; the right side is normal.
