 larger than the lateral, separated from each other by five times their 

 diameter and from the lateral by one-half their radius; anterior eyes 

 in a procurved line, equal, the median eyes very narrowly separated 

 from each other, separated from the lateral eyes by two and one-half

 long. Clypeus narrower than ocular area. Femora of the legs pro-

 a little smaller than the latter, separated from each other by their 

 radius and from the lateral eyes by their diameter. Median ocular
