between tlie other two, and the third is plainly narrower than 

 the cephalothorax. The cephalothorax is not so high as in Phil- 

 aeus, Phidippus and Palestrina. The cephalic part is only 

 slightly inclined, while the thoracic is nearly flat in the first 

 half, and then slopes off gradually. 



We have specimens of vestita, the type, from 'New South 

 Wales and Victoria. The relative length of the legs in the male 



is 1423, and in the female 4123. 



Mollika gen. nov.

 serling, Plate XCIY, figs. 7, 7a, 8-8c. 



The cephalothorax is high, massive, and convex, and is nearly 

 as wide as long ; the sides slant outward from the upper surface 

 and their outline from the front to the back is gently rounded, 

 the widest point being behind the dorsal eyes. The cephalic 

 part is inclined, and the thoracic falls in one slope from the 

 second row of eyes to the lower border. The quadrangle of the 

 eyes is one-fourth wider than long, a little wider in front than 

 behind, and occupies two-fifths of the cephalothorax. The an- 

 terior eyes form a slightly curved row, the middle ones being 

 «ubtouching, and the lateral a little separated from them and 

 tw»-thirds as large, the relative size being the same as in Zeno- 

 doriis, although the eyes, as a whole, are smaller. The second 

 row is a little nearer the first than the third. The third row 

 is as wide as the upper surface, but not so wide as the cephal- 

 othorax because of the widening out of the sides from above 

 below. The legs are 1432, the first being plainly the longest, 

 while the others are nearly equal. 



This genus, which we form for Pliilaeus metalescens L. K., 

 differs from most of the larger genera of the Phidippus group in 

 the sloping thorax and the larger lateral eyes of the first row. 

 In these points it agrees with Zenodorus, but this genus bulges 

 out widely at the front end of the cephalothorax, while Mollilca 

 is widest in the middle. Into this genus we put Joins nvicro- 

 phthalrnus L. K.
