Gabella sarawakensis, n. sp. 



cT Ocular tuberete smooth; broader than high seen from in front. 

 Scutum foveolate with a single spine. Tibia of the palps three times 

 longer than broacl. Femur 18 times longer than second joint of the 

 antennae. Trunk blackish with melallic shade above. Cephalothorax 

 on each side of the ocular tuberete with a yellow spot, covered with 

 a white waxy stuff. Tip of tibia IV yellow. 



Cephalothorax. — Cephalothorax almost triangular. The first 

 transverse ridge just behind the ocular tubercle rather low ; the 

 second, which forms the hinder margin of the cephalothorax, is better 

 marked; the area between these two tergites is in the middle rather 

 short, but widened out laterally. Frontal processes rather stout and 

 diverging, each terminating in a few short branches. Frontal emi- 

 nence slightly marked and smooth. The depressed median triangle is 

 not visible. The surface is between the spots towards the base of the 

 ocular tubercle provided with rather indistinct impressions; the sur- 

 face of the spots themselves is almost smooth or with vevy low de- 

 pressions, but with a depressed darker cross in the middle. The head 

 is foveolate along the anterior ridge; and so is the area between the 

 two ridges in the middle, but laterally it is granular. 



Tubercle. — The summit of the ocular tubercle is longitudinally 

 grooved and has a few hairs, but no teeth or granules. Seen from the 

 front it is much broader than high, rather suddenly narrowed just 

 beneath the eyes and slightly foveolate at the base. The tubercle is 

 seen from the side observed to be directed backwards, the anterior 

 side being the longer and sloping, the posterior being distinctly rounded; 

 it is as long as high anteriorly. The diameter of the eyes is equal 

 to about two thirds of the distance between the eyes, and much shorter 

 than the distance from their lower margin to the base of the tubercle. 

 Eye placed nearer to the front than to the posterior margin. 



Abdomen. — The scutum is raised towards the single almost 

 smooth spine, more steeply from the sides towards the middle than 

 from before backwards; the anterior and posterior slope is almost 

 equally steep. No traces of the segmentation are visible. The whole
