44 SJÖSTEDTS KILIMANUJARO-MERÜ EXPEDITION. 20: 3. 



Ventral side (PI. 3, fig. 23.) 



Tvitosternum (PI. 3, fig. 15). The trunk short and stout, somewhat con- 

 stricted near the base ; ventral side f inely punctured ; at the anterior end two short 

 appendages; two very narrow pectinate slips, vvhich are however not lateral, but one is 

 ventral, the other dorsal : thus they are congruent and appear to be only a single slip. 



The jugular shields (PI. 3, fig. 18) are thin and hyalin, well chitin- 

 ized only at the base, internally; the inner (median) edge is divided into 5 slender 

 teeth, 3 of which are three times as long as the others and placed close together in 

 the distal half; of the other two one is placed at the proximal corner, the other 

 half way between the latter and the other teeth. 



Sternal sliield long, narrow. The anterior side slightly concave, with a small, 

 Sharp, median projection. The lateral edges are thin blades, covering the proximal 

 part of the endopodal shields and slightly concave on a level with coxse II and TV ; the 

 greatest width is on a level with coxse III and at the acute posterior corners. The 

 posterior margin is concave and contiguous to the anterior margin of the ventri-anal 

 shield. The shield bears 6 pairs of small, submarginal hairs; one on a line with the 

 anterior margin of coxse II, one on a line with tlieir posterior margin ; 2 between 

 coxse III, one on a line between coxse III and IV and one on a line with the hind 

 margin of coxa IV. The shield is sculptured by small, circular, shallow, depressed 

 spots. 



The endopodal shields of the usual shape, fused with the metapodal shields. 

 The ventri-anal shield broad, semilunar, with convex anterior margin; 6 pairs of small 

 hairs. Anal aperture rather large, square-oval, pointed posteriorly, with two pairs of 

 hairs. The Stigmata are situated in the bottom of foveolse pedales III, a little out- 

 side and in front of the centre. The peritrema ascends the anterior slope of the 

 foveola in a curve outwards, winds twice inwards, once outwards, runs outwards along 

 the anterior edge of the mesopleural ridge and doubles its top, bends inwards in a long 

 even curve along the bottom of the foveola pedalis and beneath the free tip of the prop- 

 leural ridge, and continues forward to a level with the anterior sideof coxa I. 



Epistoma (PI. 3, fig. 10.) of the usual shape; the proximal half base narrows 

 abruptly at the top to anarrow, finely fringed slip. The mandibles (PI. 3, fig. 30). The 

 chela slender, constricted atthe base, narrowing anteriorly. Even the upper jaw seems to 

 be movable by means of an interior, long, narrow and chitinous projection, to which 

 a tendon is attached. Upper jaw broad, narrowing towards the tip, with broad inner 

 edge, provided with 5 blunt teeth, alternating with the 4 teeth of the lower jaw. 

 The hypostoma (PL 3, fig. 29). Only 3 pairs of rather stout, feathered hairs, placed 

 in two longitudinal, parallel rows. The posterior pair is stouter and shorter and cur- 

 ved towards the middle ; the median pair is twice as long as the others and finely 

 pointed. The maxillary lobes are placed laterally, and are nearly vertical ; they 

 are weak, with narrow base, and allmost parallel, only very slightly converging 

 sides; the anterior side is deeply excavated in the middle, thus forming two horns of 

 which the lateral one is laigest. The maxillary plates narrow, lanceolate, without 

 fringes; near the tip on the external side with a short sUp. The maxillary palps
