Furthermore, I have examined four specimens captured in 

 liotliouses of the MuseuQi in Paris. 



Remarks. — This species is closely allied to S. uuguicu- 

 lata, but differs by the claws on the posterior legs, the 

 posterior claw on the first pair of legs, besides by more 

 numerous and shorter seta) on the distal half of the antenna;, 

 etc. 



Appendix. — From three localities in the southern half of 

 South America I have seen four specimens which probably 

 belong to this species. Three of these specimens have 

 acquired the full number of legs, and measure from 2*6 to 

 3'2 mm.j only one of their antennae has been completely 

 preserved, and it contains nineteen joints. They agree 

 essentially with S. caldaria, and the differences observed 

 are small. The seta; ou the antennal joints are a little 

 lunger than in S. caldaria, but as to the other features 

 mentioned above quite similar; the last pair of legs with 

 the tarsus a little less slender, four and a half to four 

 times longer than deep, with seven or six dorsal seta; in the 

 anterior row, its anterior claw slightly shorter than in the 

 form from the hothouses. I am inclined to consider these 

 South American specimens as belonging to the original form, 

 from which the specimens in the European hothouses have 

 descended; but my American material is scanty, only moder- 

 ately preserved, and the specimens perhaps not quite full- 

 grown, wherefore I do not venture to decide the question 

 with absolute certainty. The American specimens have been 

 collected by Dr. Silvestri in the following localities: — 

 Gruayaquil in Ecuador; Cuyaba, in the province Matto 

 Grosso, Southern Brazils ; and Paraguari in Paragua}'.
