Icius Simon. I use this genus as it has been used by Keyserling 

 and Peckham to include several species that must soon be separated 

 into two or three genera. I.- mitratics and palmarun resemble J)e7i- 

 drypJuDites, but have the cephalothorax more flattened, the abdomen 

 narrower and longer, and the front legs of the males more elongated. 

 The other species approach Epiblemum and Menemerus. They have 

 the cephalothorax elongated, the colors dark and the hairs and scales 

 very small and partly iridescent. The legs are marked with longitu- 

 dinal lines and the front pair much elongated. I. p)almarum, mitra- 

 tus, elegans, hartii, formicarius, page 232 to 236. 



Marptnsa Thorell = Marpissa Simon. Cephalothorax and abdo- 

 m.en much flattened and both widest across the middle. Cephalo- 

 thorax very low in front, the front eyes touching its lower edge. 

 Lateral eyes half their diameter from the front pair. Mandibles 

 small. Legs 4, 1, 2, 3, in females and 1, 4, 2, 3, in males. 31. fa- 

 miliar is, p. 237. 



Epibleniiutn Hentz = Calliethera Koch and Simon. Cephalothorax 

 more than half longer than wide, a little widened in the middle and 

 depressed in the middle between the cephalic and thoracic parts. 

 Abdomen oval, not much longer than the cephalothorax. Legs 

 4, 1, 2, 3, in females and 1, 4, 2, 3, in males. Mandibles of the males 

 elongated and turned forward. Distinct white markings on cephalo- 

 thorax and abdomen. E. scenicum, page 238. 



Mene7yierus Simon. Cephalothorax half longer than wide, widest 

 a little behind the middle, flattened above, and with a deep groove 

 across the middle. Legs 4, 1, 2, 3, or 1, 4, 2, 3, front legs thickened.
