at least one-third wider than long, wider behind than in front; ante- 

 rior row of eyes inore or less curved, the middle slightly separated, the 

 lateral at least one-half as large, separated from the middle by from 

 one-third to two-thirds their own diameter; eyes of second row very 

 sHghtly nearer the lateral than the dorsal eyes; dorsal as large or 

 nearly as large as the lateral eyes, at least as far from each other as 

 from the lateral borders, forming a row narrower than the cephalo- 

 thorax at that place. Clypeus not more than half as high as middle 

 eyes. Labium about one-half as long as maxilte, usually longer than 

 wide, sometimes as %A'ide as long. Anterior cox^ separated by w^idth 

 of labium or by a little less. Legs ( 5 ) 1, 2, 4, 3. 1, 4, 2, 3. 1, 4, 3, 2; 

 ( J- ) 1, 4, 2, 8. 1, 4, 3, 2. 4, 1, 3, 2; first pair stoutest, second next. 

 Femur and tibia of the first enlarged, stouter than patella and much 

 stouter than metatarsus and tarsus; tibia and patella of the third 

 shorter than tibia and patella of the fovu'th. Femoral, tibial and 

 metatarsal spines on the four pairs; metatarsi of the fourth usually 

 spined throughoiit their length. 

 This genus differs from PMdippus in having the eyes of the second row 

 nearly half way between the lateral and dorsal eyes; the width of the ocu- 

 lar area, moreover, is frequently greater in proportion to its length.

Cephalo thorax: length 4; width 3.4; height 2.1. 



Legs 8.4, 6.6, 7.2, 9.2; patella and tibia of the first, 3.6; patella and tibia of 

 the third, 2.8; patella and tibia of the fourth, 3.6; metatarsus and 

 tarsus of the fourth, 3.1. 



Cephalic part plane, and but little inclined; thoracic convex, falhng ab- 

 ruptly a little way behind dorsal eyes. Ocular area one-third 

 wider than long, much wider behind than in front. Anterior eyes small, 

 in a moderately curved row; lateral one-half as large as middle eyes, 

 separated from them by two-thirds their own diameter; dorsal a lit- 

 tle smaller than lateral eyes, further from each other than from lat- 

 eral borders. ClypeUs one-third as high as middle eyes, vertical; 

 falces as wide as first row of eyes, twice as long as face, vertical, 

 diverging. Maxillge parallel, enlarged and rounded at extremity. 

 Labium a little more than one-half as long as maxillae, about twice as 

 long as wide, contracted and blunt at tip. Sternum twice as long 

 as wide, deepset, a little rounded behind. Anterior coxse separated 

 by less than width of labium. 



Coloration : Cephalothorax black with long stiff black hairs on the eye- 

 region, which form one or two small tufts on each side. Clypeus 

 covered with short white hairs. Abdomen black, encircled except at
