218 Mr. C. Warburton on Spiders from Madeira. 



T^h^abdomen is oval, slightly narrower behind; itsprevailing 

 colour is a reddish yellow, due to certain characteristic 

 markings on a dark background. Its anterior border is 

 whitish, and two conspicuous white spots are connected with 

 this border by reddish bands, emphasized by a dark inter- 

 mediate space. The middle of the abdomen is reddish 

 yellow, with paler divergent markings, which are best under- 

 stood by reference to the figure. The lateral borders of the 

 abdomen are reddish yellow and give out streaks towards 

 the median angular lines. 



The plastron is red-brown and the underside of the abdo- 

 men is pale with a dark median longitudinal line. 



The legs resemble the abdomen in colour, being of a 

 reddish yellow, broadly but not very distinctly annulated 

 with brown. The first pair are darker hued and very 

 powerful, with the tibiae and metatarsi armed with strong 

 spines. The palpi are of the colour of the posterior legs. 



I have named this handsome spider after Mr. W. R. 

 Ogilvie- Grant, whose interesting collection contains three 

 females of this species.

 North-African Spiders," K. Svensk. Vet.-Ak. Handl. xiii. no. 5, 

 p. 60. 



The collection of Mr. Grant contains a mature female 

 spider \s hich answers well to the description given by Thorell 

 of the above species. As that eminent author has confined 

 himself to a Latin diagnosis without figures, I have thought 

 it well to include drawings of the spider in the present memoir 

 (PI. XIV. figs. 4, 5, and 6).

A mature female of this fine species is included in the 

 collection of Mr. Clark, and five in that of Mr. Grant. It 

 exhibits considerable variation in size.
