;ire;i. Tlu' slriu'tiiie ol' llic median oigan is very flilïieiill lo unravel; il seems lo 

 consist of two remarkably shaped fissures (PI. I, tig. (> c). The posterior one is 

 narrow, shaped like a horse-shoe with the free tips directed forwards. Between 

 the tips of the legs another, narrower fissure is found with a tiny branch directed 

 forwards and inwards. The outer margin of these two fissures are rather chilinized, 

 (he inner less so, and the area between them is thinly skinned, a median denser 

 portion excei)ted. Near to the exterior margin I have only seen two fissures, placed 

 apart from each other (tig. 6 b, /'■'); above there are three very short almost longi- 

 tudinal fissures (PI. 1, fig. 6 a, Z'^). 



V. Garypinus nobilis n. sp. (PI. I, figs. 7 a-c). 



The labrum is very broad in front and is behind a moilerate convexity 

 widened out again (PI. I, fig. 7 a); there is no jjosterior free portion prolonged at 

 the back of the maxillae. The anterior portion is mounted with two broad ridges 

 (fig. 7 a, a), which almost touch each other in the front but behind are well 

 separated from each other. On each side of these and partly in front of them a 

 narrow short ridge is found (fig. 7 a, c). The median pair of ridges {a) is continnetl 

 behind into the lateral margin of the labrum (m) and overlapped by the inwards 

 directed wing of the maxillae (fig. 7 a, b). The hinder pari of the maxillae, which 

 is placed behind the line where the articulate-membrane of the antennae is fastened 

 (fig. 7 a, /), is more thinly-skinned than the part in front of it. Along the hinder 

 margin of the maxillae a similar, but less complicated system than that of Chelifer 

 Geof. is found (figs. 7 a, b and d, cf. fig. 8 a). The paired bodies, which cover the 

 base of the labrum (fig. 7 a, /i) are moderately developed. The lamina ma.villaris 

 superior is rather long and broad (fig. 7a, Is), while the lamina inferior is extremely 

 small (fig. 7 a, li). The manducatory part is well developed but not so distinctly 

 limited as in Garypus L. K. 



The interior marginal fissure is placed far behind the tip and a little removed 

 from the inner margin (PI. 1, fig. 7 b, /-) ; it is rather narrow and includes an 

 almost circular, thinly-skinned area, beneath which a short, hooked and outwards 

 directed body is jtlaced (fig. 7 c). The median organ (fig. 7 b, /') seems to consist 

 of al least one almost circular fissure, and appears similar to an arliculate-cavily; 

 its minute, as it seems complicated, structure I was not able to unriddle. Near to 

 the exterior margin, just behind the articulate cavity at least two transversely 

 placed fissures arc found (fig. 7 b, /''), and dorsally in the middle two longitudinal 

 ones are placed (fig. 7 a, /"'). 



VI. Chelifer nodosus Schrank. (PI. I, fig. iS a). 



The structure of the labrum as well as of the maxillae is much more com- 

 plicated than in other forms and it is difficult to distinguish the parts of the two
