The tlioracic falls gradiiallv in tlie first third, and then steeply. 

 The quadrangle of the eyes occupies two-fifths of the cephalo- 

 thorax, is one-third wider than long, and is a little wider behind 

 than in front. The front eyes are small, and form a slightly 

 curved row ; they are all close together, and the middle ones are 

 less than twice as large as the lateral. The second row is nearer 

 the first than the third, and the third is nearly as wide as the 

 cephalothorax at that place. The whole spider is covered with 

 bright greenish golden hairs, the green tint being less marked on 

 the abdomen than on the cephalothorax. When the hairs are 

 rubbed off, the abdomen is light brown with two darker bands 

 on the anterior part, which merge into dark chevrons behind, 

 and dark oblique streaks on the sides. The falces are light 

 broAvn, vertical, and rather long. The legs and palpi are yellow 

 with some white scales. The lip is wide and short, the maxillae 

 tAvice as long, and rounded. 



We have many females from San Rafael, Mexico, sent to us.

The cephalothorax is very little longer than wide ; the widest 

 point is behind the dorsal eyes; the upper surface rounds off 

 gently in each direction from the dorsal eyes, the thoracic slope 

 becoming steeper after the first half. The sides are not much 

 wider below than above. The quadrangle of the eyes is one- 

 third wider than long, wider behind than in front, and occupies 

 two-fifths of the cephalothorax. The front eyes are rather small 

 and form a straight row, the middle ones touching, and a little 

 less than twice as large as the lateral, which are separated from 

 them. The second row is a little nearer the first than the third, 

 and the third is nearly as wide as the cephalothorax at that place. 

 We have no perfect specimen, but in one which is in fairly good 

 condition the upper surface of the cephalothorax seems to have 

 been entirely covered with yellow hairs, excepting a white spot 

 between the dorsal eyes, and the sides are entirely covered with
