Posterior eyes in a slightly recurved line, equal, the median eyes 

 a little nearer the lateral than to each other, interocular spaces less 

 than the diameter of the eyes; anterior eyes in a straight line, the 

 median eyes smaller than the lateral, separated from the lateral by 

 their diameter and from each other by a little smaller interval. Median 

 ocular area wider than long. 



Ceraticelus bulbosus Em. 



This species is very closely allied to C. fissiceps Em. In the male 

 the posterior lateral eyes are nearer the posterior median, and the 

 anterior lateral eyes are considerably nearer the anterior median than 

 in fissiceps. In the female the posterior median eyes are separated 

 by their diameter, and the anterior lateral eyes are much nearer to the 

 median than in fissiceps.

Posterior eyes in a very slightly recurved line, the median eyes 

 slightly larger than the lateral, separated from each other by their 

 diameter and from the lateral by a little smaller interval; anterior 

 eyes in a very slightly procurved line, the median eyes smaller than the 

 lateral, separated from each other by three-fifths their diameter and 

 from the lateral by four-fifths. Median ocular area about as long as 

 wide. Clypeus narrower than ocular area.
