COLLECTED IX DUTCH NEW GUINEA. 447 



At the base the abdomen is dark greyish-brown mottled with yellow, followed on 

 each side by a broad area of bright yellow with a few brown spots thereon, running 

 into a yellow area the whole length of each side of the abdomen ; the central area of 

 the back is covered with a brown pattern beginning with a median broad triangle 

 that separates the above-mentioned yellow areas, thence it broadens out into a shield 

 deeply scolloped at the sides, which gradually narrows into a long streak reaching 

 to the posterior end. In the interior of this shield are paler patches, two near 

 the broad anterior end, one each side of the median line, and others successively 

 smaller on the median line. On the yellow sides are about five faint brown perpen- 

 dicular lines merging into the dull greyish-brown of the underside. On this, in front 

 of the epigyne, is a pale yellowish area. Between the genital groove and the spinnerets 

 is a narrow darker shield pointed at each end ; on this, one below the other, are four 

 pairs of small round dark spots and two rather large paler yellow spots a little in front 

 of the spinnerets. The latter and the epigyne are yellow-brown. 



The cephalothorax is longer than broad, truncate in front, rounded at the sides. 

 The somewhat raised cephalic part is separated from the thoracic by well-marked 

 depressions, its rear end extending to a fovea almost on the rear slope. The former is 

 nearly bare in the middle, but the sides and the thoracic part are thickly covered with 

 rather coarse hair. The front median eyes are one-third wider than the rear median, 

 one and a half times their diameter apart and two and a half times from their 

 laterals. The rear median are only two-thirds of their diameter apart and their 

 diameter from the front median. The side eyes, the diameters of which are 

 one-third smaller than those of the rear median, lie half a diameter apart on a 

 rather large tubercle, the front eye being directly below the rear one. The clypeus 

 is about as broad as a front median eye. 



The mandibles are strongly geniculate at the base, as long as the front of the 

 cephalothorax is broad ; the fangs long and powerful, but slightly curved. On the 

 inner side of the falx-sheath are three teeth, the middle one larger than the others. 

 On the outer margin are four, of which the third is the largest and the fourth smallest. 



The lip is broader than long, pointed anteriorly, half the length of the maxillee ; the 

 latter are straight in front, where they are broadest. 



The sternum is long and shield-shaped, hollow in front and at the insertion of the 

 C0X8S, the rear pair being contiguous ; it is thickly covered with rather coarse hair. 



The legs are moderately long and tapering, not very stout, but furnished with short 

 powerful spines. 



The abdomen is ovate, nearly as broad as long, broadest one-third of its length from 

 the base ; thick at the sides and sparsely covered with short, fine, recumbent hair and 

 long upstanding bristles on circular roots. 



The epigyne is formed of a scape springing from the upper part of a bulbous base, 

 at first bent back and then turned over towards the rear, the anterior two-thirds pointing
