 fossa short and very deep. 



Eyes subequal, anterior eyes separated from each other by a space equal to three 

 times their diameter. Space between the eyes of the second row about e([ual to 

 their diameter; these eyes are removed from the anterior by a space equal to the 

 last mentioned. Posterior eye row strongly recurved, the middle eyes a little far- 

 ther apart than the eyes of the second row, the posterior lateral eyes removed from 

 the middle by a distance equal to three times their diameter. 



Cephax twice as long as broad. Legs on all joints but the femora with a few

 prominent transverse ridge between the two eye rows, extending outward, forming 

 a sharp and prominent point on each side. 



Eyes eight, in two transverse rows, the anterior straight row situate at the vertical 

 front of the cephalothorax before the ridge, the i»osterior slightly recurved row 

 with the two middle eyes on the flat dorsal surface and the lateral eyes on the pos- 

 terior angle of the projecting point ol' the ridge. The anterior lateral eyes the 

 largest; space between the anterior middle eyes ei^uals about one and one-half of 

 their diameter, and they are about twice as far removed from the anterior lateral 

 eyes. The posterior lateral eyes a little larger than posterior middle ; the eyes of 

 this row are about equidistant. 



Mandibles weak, short, directed backward. Maxilhe inclined over the labium, 

 truncate at apex, labium broader than long, subtriangular, rounded at tip.
