Epistoma (Text-fig. 14). Besides the three teeth mentioned and deUneated by 

 TrouesSART there is often a small tooth more laterally on each side. 



Hypostoiiia upon the whole correctly delineated by T. with the e.xception that 

 in reality the maxillary lobes are not fork-shaped but simple. The four usual pairs 

 of hypostomatic hairs present. The palpi (PI. II, fig. 2) with five free joints; the 

 second (first free) third and fourth of equal length; the second and fourth half as 

 wide as long, cylindrical, the third one is thickened and on the ventral side provided 

 with a large, rounded, knob- like projection with a longitudinal groove in the top; 

 5th and 6th joints together as long as the 4th, the 6th being only half as long as 

 the 5th and richly provided with hairs. Hairs of palpi simple, arranged as follows: 

 II one ventral; III three dorsal, one e.xterior, one interior; IV three dorsal, one 

 exterior, two interior of which one is feathered; V two ventral, 10 — 12 terminal. 



The iiiandiblcs (PI. II, fig. 20). The lower jaw slightly shorter than the upper 

 one, with one large, strongly curved terminal tooth and one smaller, sharply pointed, 



median one. It has a long, 

 slender, needle-shaped, up- 

 wardly curved, pointed calcar 

 mandibuli attached with large 

 base to its outer side; calcar 

 nearly twice as long as the 

 chela. The upper jaw is 

 straight for 3 ^ of its length, 

 provided with one large ter- 

 minal tooth and three other 

 teeth of which the anterior 

 one, situated just in front of 

 the sense hair, is extremely 

 small, while the other two are 

 as large as the terminal one. 

 The legs. Legs I (PL II, fig. 23) long, slender with small, demarcated basifemur 

 and basitarsus. Coxa slightly curved, with a small, median, ventral projection; tarsus 

 of uniform thickness throughout. 



Legs II') (PI. II, fig. I) thick, with large, slightly upwardly curved calcar 

 fenioralis provided with a sharp dorsal edge; processus axillaris small, straight, 

 sharply pointed; processus stridularis genualis and tibialis nearly of the same 

 hatchet-like shape, with the front angles projecting sharply. The tarsus has a very 

 remarkable shape (Text-fig. 13). It is just in front of the demarcation between 

 basi- and telotarsus curved downwards and on the internal side provided with an 



') In the description of legs II I have adopted the terminology proposed by Berlese.
