NOTfiS ON BRITISH SPIDERS. 21 



The margins of this band are slightly indentated, and sometimes 

 dentate, more so in some examples than in others. Sides brown ; 

 underside pale dull yellowish to brown, with two longitudinal 

 black-brown stripes, converging a little towards the spinners ; 

 these are of moderate length and strength and directed backwards. 



The female closely resembles the male in colours and markings ; 

 but in some examples the central white band on the cephalo- 

 thorax runs further forward in a more drawn-out pointed form, 

 and the white abdominal band is more sharply defined and less 

 dentated or irregular on the edges. The genital aperture is of a 

 very characteristically distinct form. 



A considerable number of both sexes of this spider, in all 

 stages of growth, have occurred in one of the hothouses of the 

 Royal Gardens at Kew, and have been kindly sent to me by the 

 Curator, Mr. G. Nicholson. Mr. Nicholson tells me that they 

 live within the folded leaves of Bromeliads, imported from Brazil. 

 It is a fine and distinct species, and appears to be as yet 

 undescribed ; its generic position does not seem to be quite 

 certain. Mr. Peckham thinks it is a Plexippus, C. L. Koch. 

 Mons. Simon considers it a Cytea, L. Koch. To me it seems to 

 be probably an Hasarius, another species of which, H. Adansonii, 

 Sav. (the type of the genus), also occurs in a similar semi- 

 naturalised state in the Kew Gardens.
