luiddle-line of tliis is a longitiidinal broad light brownish 

 band behind the middle continued by four transverse — .- 

 shaped bands of the same colonr. These markings are best 

 visible on young spiders. The sides and the venter are one- 

 coloured light brownish. (As the specimens are conserved in 

 alkohol, it is very possible that the gronnd-colonr originally 

 has been whitish.)

Of this species the collection contains several adult fe- 

 niales from the upper and lower part of the Aysen Valley, 

 Jan. 1897. 



The description published by Mr. Simon is, as said above, 

 very short and the characteristics are nearly exclnsively 

 taken from the colour. He describes the abdomen as being 

 white whith a broad oval, backwards tapering, brown-violet 

 dorsal band, on each side with blackish markings. From this 

 description my specimens diifer in a high degree. But other- 

 wise there is nothing, that shonld induce me to constitute 

 a new species.
