320 PROCEEDINGS OF THE ACADEMY OF [April, 



Posterior eyes in a strongly recurved line, the median eyes a little 

 larger than the lateral, all eyes separated by about twice the diameter 

 of the lateral ; anterior eyes in a straight line, the median eyes slightly 

 smaller than the lateral, separated from each other by one-half their 

 radius and from the lateral by three times their diameter. Median 

 ocular area slightly longer than wide, clypeus narrower than ocular 

 area.

Posterior eyes in a slightly recurved row, the median eyes smaller 

 than the lateral, separated from each other by their radius and from 

 the lateral by three-fourths their diameter; anterior eyes in a slightly 

 recurved line, the median much smaller than the lateral, separated 

 from each other by their diameter and from the lateral by nearly twice 

 as much. Median ocular area a little longer than wide, clypeus nar- 

 rower than ocular area. 

 Ceraticelus formosa Banks. 



9 . — Posterior eyes in a nearly straight line, equidistant, the median 

 eyes a little larger than the interocular spaces; anterior eyes in a 

 straight line, the median eyes smaller than the lateral and almost con- 

 tiguous, while separated by more than their diameter from the lateral. 

 The inframamillary and epigastric sclerites of the abdomen only slightly 

 developed, while the dorsal sclerite is very thick, confined to the an- 

 terior part of the dorsum and squarely truncate behind.

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

 separated from each other by their diameter and from the lateral by 

 three-fourths as much; anterior eyes in a straight line, the median 

 eyes much smaller than the lateral, separated from each other by one- 

 third their diameter and from the lateral by a little less than their 

 diameter. Median ocular area wider than long, clypeus much wider 

 than ocular area.
