$ , Length of cephalothorax 2.5 mm; of abdomen 4.5 mm. 

 Legs 12, 9.5, 8.5, 8.2. Falces 2.3 mm. 



? . Length of cephalothorax 3 mm; of abdomen 5.2 mm. 

 Legs 10, 9, 8, 7.8. Falces 1 mm. 



Cephalic part not quite so long as thoracic. Quadrangle of eyes one-third 

 wider than long. Eyes of first row three times as large as those of 

 second row. Clypeus one-fourth as high as anterior eyes. Falces. 

 ( 6 ) horizontal, diverging, rounded, four times as long as face; on 

 the distal end of each falx, on the inner edge, are two stout projec- 

 tions; fang as long as falx, curved. Falces ( $ ) rather stout, nearly 

 vertical, twice as long as face; fang one-half as long as falx. Max- 

 iUee rounded and a little enlarged at their extremities. Labium a 

 httle longer than wide, more than one-half as long as maxillae, 

 blunt; m $ narrow at the base. Legs 1, 2, 3, 4. Femur of the first 

 ( $ ) quite, ( 9 ) nearly equal to femur with patella of the second. 

 Metatarsus of the first ( $ ) bent, with fine fringe of hairs at distal 

 end. Spines rather long. 

 Coloration (under alcohol): Upper surface of cephalothorax and falces 

 fight yellow ($) with tinge of red; a short dark median longitudinal 

 fine on anterior thoracic part. Sternum, coxae, mouthparts and up- 

 per and under surface of abdomen pale yellow. Legs pale with 

 slightly darker spines and black tips, ( 3 ) tibia of the first darker to- 

 ward extremity with some short dark hairs; matatarsus of the first 

 brown at distal end with fringe of short brown hairs. 

 Habitat: Southern United States. 



Hentz describes this species as foUows: "Tender grass-green; cephalo- 

 thorax with some orange- colored hairs near the eyes, and a httle black fine 

 on the disk; abdomen with six or eight black dots, sometimes wanting." 

 The green color evidently fades to a light yeUow in alcohol. Hentz prob- 

 ably never had a mature male, as he makes no reference to the long hori- 

 zontal falces.
