terminating at some distance before tins point; the front 

 seta is as long as the short claw, and very robust. 



Cerci (fig*. 2 A:). — In larger specimens from a little more 

 than four and a half to five times longer than deep. They 

 are clothed with a large number of stiff, rather short sette, 

 nearly equal in length at the end and before the middle, and 

 none of them half as long as the depth of the cerci. The 

 terminal area looks upwards, and generally a little outwards ; 

 it is a little long'er tlian the setfe. The apical seta is strong-, 

 as long as or somewhat longer than the depth of the cerci. 



Length. — 3 to 3*6 mm. 



Locality. — La Moka, in Venezuela, August 1st, 1891 (F. 

 Meinert). 



Remarks. — Tins species is distinguished from all other 

 forms by the very elongate anterior claw on the posterior 

 pairs of legs. Other useful features have been pointed out in 

 the analytical key. 



4. Scutigerella caldaria, n. sp. PI. 2, figs. 3 a — Sg. 



Material. — Many specimens from hothouses. Some South 

 American specimens probably belonging to this species are 

 dealt with in the "Appendix" to the description. 



Head. — Seen from above it is proportionately a little 

 narrower, and its lateral angles a little less pronounced than 

 in S. unguiculata ; the longest lateral seta is considerably 

 shorter than the breadth of the proximal antennal joints. 

 The central rod without visible frontal branches or posterior 

 rods as in S. unguiculata. 



Antenna?. — The number varies generally from twenty- 

 three to twenty-eight. The seta9 on the inner side of the 

 proximal whoi-ls not longer than those on the outer side. 

 The secondai-y whoid begins on the lower side on the seventh 

 or eighth joint, but already at the middle of the antenna? it is 

 conijdetely developed above and on the outer side. On the 

 same distal half at least one seta-, often two setic, are found 

 on the lower side, behind the second whorl (fig. 3a), and the 

 inost distal joints have even four sette behind each other on
