Head clothed with flat scales ; palpi short and spatulate in

 Second segment of the antennae much larger than the following

 border spiny. 



The 9 palpi are apparently of three segments, the basal one 

 very small, the second smaller than the third, which is as long as 

 the rest of the palp, swelling apically, the apex truncated, on
