48 SJÖSTEDTS KILIMANDJARO-MERTT EXPEDITION. 20: 3. 



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



The tritosternum; the trank not quite three times as long as it is broad; 

 tlie proximal half Avith parallel sides, sligthly narrowing distally ; the feathered slips 

 fused with their proximal ' c, attaining three times the length of the trunk. All the 

 shields are fused together to one shield, anteriorly fused with the dorsal shield ; the 

 ventral shield long and triangulär, with the top backward; the lateral edges slightly 

 wavy. The sternal portion narrows gradually backwards and is very narrow 

 between coxae IV \ owing to the great width of the foveolae pedales IV. The usual 

 four pairs of hairs present, in their usual places. 



Ventri-anal portion with 4 pairs of hairs, placed in two rows, converging 

 backwards: one pair behind coxse IV, two in the middle of the shield, and one pair at 

 the side of the oval apertvxre. Anal aperture oval, close to the posterior end. 

 Stigmata in the iisual places, rather large; the peritremata run forward to the 

 anterior margin of foveolae pedales I, nearly becoming dorsal. 



Epistoma rather broad, triangulär, with slightly convexe edges, divided into 

 fine, slender teeth arranged in two groups of 6 — 7 each with a smooth interval 

 between them ; as a part of the left side of the top is broken off in the Single spe- 

 cimen I have examined I am not certain of its structure ; on the right side however 

 one notices a lateral, pointed lobe, the extei'nal edge of which is divided into 6 teeth, 

 and which is divided in 3 teeth at the top ; on the left (median) side there is an 

 excavation. The mandibles (PI. 3, fig. 27): the lower jaw is broader than the 

 Upper one and of equal width throughout to the articulation of the calcar. Ter- 

 minal tooth not strongly curved, slender; one strong, backwardly directed tooth in 

 front of the middle; calcar mandibuli slightly S-curved, tapering gradually towards 

 the top, with a small ventral tubercle near the top; exactly as long as the distanee 

 from its base to the base of the Joint. Upper Jaw with two teeth opposite to those 

 of the lower jaAv. 



The maxillae. (PI. 2, fig. 29.) The maxillary lobes long, slender, with 

 narrow base and long straight, slender horns, curved inwards only at the base. There 

 is a pair of long, narrow hyalin membranes, to all appearance attached to the inner 

 (median) side of the demarcation line of the lobes ; the membranes are curved slightly 

 inwards at the top. These membranes resemble very much those which Oudemans 

 has described in Pachylcelaps ensifer Oudms^ The maxillary plates are very thin, 

 lanceolate, finely fringed, fused with their proximal Vs. Lingula very long, twice as 

 long as the maxillary lobes and hairy. 



The palps are long and slender, the joints decreasing in length towards the 

 top; without any appendages; first Joint dorsally bare and as usual, ventrally with 

 two long hairs; second Joint on the inner side, proximally, provided with one poniard- 

 shaped bristle; S'«^ Joint with 2 bristles in a transverse row on the inner side in the 



' In this respect the present species resembles Plaßiiilalaps (Paehylcelaps) latus Beel. froni Ja\a, of 

 which however only the female is known.
