Broteas nigrocinctus of C. Koch (Die Arachn. x. p. 14, 
fig. 763) ; so that until evidence is forthcoming that these 
transversely banded forms, which, if conspecific, must be called 
vittatus, are the same as what C. Koch described as Broteas 
bonariensis, I think it is wiser to adopt the latter name for 
the species that Thorell described as vittatus. 
The form rugosus described by Thorell as a variety of this 
species is, I think, probably a distinct species. 
Bothriurus ee sp. 1. 
(Pl. V. fig. 12.) 
g. Colour: carapace blackish, clouded or variegated with 
ferruginous ; tergites black, with a red stripe along the hinder 
border ; tail ferruginous above, the lower surface ‘of. the seg- 
ments nigro-lineate, the black lines expanding and fusing 
behind into a transverse vitta; palpi ferruginous; legs and 
ventral surface flavous. 
Allied to B. bonariensis. 
Upper surface of the trunk finely and closely granular , 
throughout ; the sterna also closely and finely granular 
throughout, the anterior ones smoother; the stigmata elongately 
ovate. 
Tail smooth above and below, the lower surface of the first 
segment obsoletely keeled beneath ; the superior and supero- 
lateral keels and the space between them granular on the 
first segment ; the supero-lateral keels obsolete on the third, 
being merely represented in front and behind by a tubercle ; 
the superior edges of the fifth smooth or granular only in front. 
The inferior lateral keels on the fifth are present and denticulate 
on the posterior two thirds of the segment, and the median 
keel is almost as long and also denticulate ; between them 
on each side there is an oblique series of denticles which 
defines in front the posterior area; the vesicle is narrow 
pyriform, net depressed below, but lightly depressed above. 
Palpi as in B. bonariensis, but with the manus a little less 
robust. 
Fectines with from 15-18 teeth. 
The first pair of feet with a single pair of spurs at the apex, 
the second with two pairs, the third and fourth with a median 
pair also. 
Total length up to 48 miilim.; length of carapace 6, of 
tail 28. 
Loc. Chili. 
The Museum has four examples 6 this species (3 ¢ and 
1 2), two being ticketed merely Chili, the others (1 ¢ and 
1 9) Coquimbo.
