Dyarcyops, nov. gen. 



Dyarcyops differs from Arhamtis L. Koch, to which it is allied, 

 in having both rows of eyes procurved, the front median eyes 

 more than their diameter apart, the cephalic part of the cephalo- 

 thorax comparatively high, the thoracic fovea straight, deep, and 

 long ; it has only a few pectinations on the superior tarsal claws ; 

 and, from the greater procurvatui-e of the fi-ont i-ow, the whole 

 eye- space is longer in compaiison with its bi-eadth than in the 

 above-named genus.

Dyarcyops andrewsi. nov. sp. (Plate XIII. fig. 10 & text- 

 fig. 25 a.) 



Cephalothorax dark reddish brown, with fine j^ellowish-brown 

 hair ; mandibles darkei' still, with brown hair or bristles. Sternum,, 

 lip, maxillfB, and coxaj rich yellowish bi-own, with long brown 

 hair, rather inclined to yellow on the maxillse and red on the 

 fringes. Legs and palpi yellow- bi'own, abdomen dai-k grey reticu- 

 lated spots on 5^ellow-brown ground. 



The thoracic part of the ceplialoiliorax is rather flat, the 

 cephalic pai-t rising somewhat abruptly from in front of the fovea, 

 which is broad, deep, and transversely sti-aight. 



The whole cephalothoi'ax, somewhat broad in front, is one-third 

 longer than broad, and longer than the patella and tibia of any of 

 the legs. The mandibles are large and extend below the base of 

 the cephalothorax. The abdomen is ovate, rather straight in 

 front : the superior spinnerets short and stout, the first joint 

 longer than the other two together, the third quite short and 

 almost hemispherical; the inferior one diameter apart. 



The front row of eyes is strongly procurved, the laterals 1| 

 diameters of the medians, having their highest pari below the 

 lower margin of the latter pair, which are one and a third of their 

 diameter apart. The rear side eyes are slightly smaller than the 

 front, and separated f I'om the latter by two of their own diameters. 

 The centres of the rear medians are on a level with the upper part 

 of the latei^als, making the whole row clearly procurved. The 

 total eye-space is well raised up and 1| times as broad as long. 



The mandibles are stout and long, well arched, and their lowest 

 point reaches to below the level of the sternum. Tlie fangs are 

 long and powerful. The rastellum consists of two rows of stout
