also (fig. 3 /)), and are more similar to those in subadult 

 specimens; tlie claws in the smaller specimens from Austin 

 are somewhat shorter (figs, oe and 3 g) than those of the 

 large specimen, but otherwise agreeing with them. I 

 cannot discover other differences worth mentioning between 

 European specimens and tbose from Texas (the cerci of the 

 large and of a small specimen are shown in figs. 3 c and 3 h), 

 but my material from the last-named locality is very scanty 

 and not very well preserved, so that I cannot decide with 

 certainty if the differences mentioned in the claws of 

 European specimens and of the well-grown specimen from 

 Texas are of any importance. I think it necessary to con- 

 sider the specimens from Texas as probably belonging to 

 S. immaculata, but this result may perhaps one day turn 

 out to be wrong. 



In 1881 A. S. Packard (op. cit.) stated that specimens 

 taken by him at Salem, Massachusetts, and near the 

 Mammoth Cave, Kentucky, differed from specimens from 

 Bohemia only by " rather longer and slenderer antennas." In 

 1886 the same author stated (' Amer. Naturalist,' 1886, 

 p. 383) that specimens from Cordova in Mexico differed from 

 individuals from the United States by being larger (5 mm.) 

 and by having some joints more in the antennas, and the cerci 

 "slightly longer," but otherwise agreeing with these. His 

 specimens from Mexico certainly belong to the same species 

 as my specimens from Texas, but whether the animals from 

 these subtropical countries differ from the specimens living 

 in Massachusetts, etc., or such northern American animals 

 from European specimens, a future student must decide. 



Dr. Y. Silvestri writes (' Zool. Anzeiger,' 1899, p. 370) that 

 he found S. i m mac u lata abundantly in Chile on his voyage 

 from Temuco to Villa llica, but specimens captured by him 

 at Temuco and S. Vicente and examined by me belong to 

 Scut, chile nsis, n. sp.^ The specimens captured by Prof. 

 Max Weber in Java and Sumatra, and determined by II. I. 



' One of the specimens belongs io a species unknown to me, but llie auimul 

 is so badly preserved tliat 1 did not venture to describe it.
