126 EDV. ELLINGSEN. 



Abdomen. The tergites and sternites glossy and nearly 

 smooth, with only a few dispersed, irregular stripes. Along 

 the posterior margins there are some fairly long, acute hairs ; 

 on the last segment some tactile hairs. 



Palps about as long as the body with abdomen extended, 

 glossy and smooth, except the hand which is sometimes slightly 

 shagreened, though the shagreen is often not visible; the hairs 

 pointed, on the outer side a little shorter than on the inner side. 

 — Trochanter with a short stalk, otherwise about as long as 

 wide, the inner side convex, the outer side concave. Femur 

 with a short, but distinct stalk, about 3 times as long as broad, 

 nearly parallel-sided, not tapering towards the extremity, the 

 inner side slightly convex, the outer side slightly concave or 

 nearly straight. Tibia with a short stalk, considerably shorter 

 than and only a little broader than femur, externally regularly 

 and strongly convex along the whole outer side, internally con- 

 vex. Hand with a distinct stalk, somewhat longer and broader 

 than tibia, with regularly rounded base and both sides mode- 

 rately convex, gradually passing into the fingers. On the outer 

 side of the hand, very near its extremity, and thus a little be- 

 hind the base of the fingers, there is a small elevation provided 

 with one or two long, tactile hairs; a couple of similar tactile 

 hairs are found on the upper and the inner side of the hand 

 near the tip, but these are not placed on any elevation. Fingers 

 very robust, gradually tapering distally, a little curved, about as 

 long as the hand. In this respect however they vary, being 

 sometimes a little longer and sometimes a little shorter. Along 

 the inner margins of the fingers there is a row of truncated 

 teeth, not very pronounced, scarcely separated from each other, 

 and the margins being thus more crenulate than denticulate; 

 this is especially the case in the movable finger. 



Mandibles of a middle size, the movable finger provided 

 with 7 to 8 small and irregular teeth. The galea is shaped 

 like a fan, but is very variable; it may be divided into 4 to 6
