colored. The males somewhat resemble the m.ale of Parnaenus 

 funehris, but the shape of the cephalothorax is quite diffeTent.

This genus is identical with Eulahes Keys. 1882 and Piri- 

 tlious Kej^s. 1883. The spiders are large, with rounded cephalo- 

 thorax and long first legs, but are not so high and massive as 

 Pliidippus and Philaeus. They are characterized by the very 

 wide quadrangle of the eyes and by the distance between the 

 lateral and middle eyes of the first row. 



The cephalothorax is moderately high and has a rounded ap- 

 pearance, both above and on the sides. The cephalic plate is 

 inclined, especially in the anterior part. The thoracic part 

 slopes off gradually in the first third and then more steeply. 

 The highest point is at the dorsal eyes and the widest point be- 

 hind thein, where there is a gentle swelling out of the sides, 

 excepting in severa, which is wildest in front. The quadrangle 

 of the eyes is about twice as wide as long, is much w4der behind 

 than in front, and occupies from two-fifths to one-half of the 

 cephalothorax. The first row of eyes is straight or somewhat 

 curved, with the middle eyes subtouching or a little separated, 

 and more or less carried forward by a projection of the cephalo- 

 thorax. The lateral eyes are separated from them by at least 

 their own diameter. The second row of eyes is nearer the first 

 than the third. The third row is about as w^ide as the cephalo- 

 thorax at that place. The relative length of the legs is 1243 in 

 the males, and 1423, 1423, or 1342 in the females. 



This genus was formed by Thorell for thoracica (Studi sui 

 Ragni Malesi e Papuani, III, p. 520). We lack this species, 

 the genus being represented in our collection by paetulus Keys.y 

 (PI. XXV, figs. 3-3b) tenuidens Keys., (Hasarius) harhatissi- 

 mus Keys., and sevei^a, a new species. In harhatissimus the 

 cephalothorax is higher than in the others, and is a little differ- 

 ently shaped. Severa approaches Anamosa of the Homalattus 

 Group, in its long cephalic part. All these species excepting 

 severa are from Australia. Possibly the type, tlioracia (Cape 

 York), is identical with S. fissidens Keys., also from Australia.
