Genera and Species of Araneidea. 177 



Family Miagrammopides. 



Genus Miageammopes (Cambr.). 

 Miagrammopes Bradleyi, n. sp. 



Adult female, length 3| lines. 



In size, form, general colours, and appearance this spider 

 is scarcely distinguishable from M. Thwaitesii (Cambr.), de- 

 scribed in Linn. Journ., Zool. vol. x.p. 401, pi. xiv.figs. 1-12«. 

 It may, however, be at once distinguished by the deep-black- 

 brown tapering band which runs longitudinally through the 

 middle of the upperside of the abdomen from its fore ex- 

 tremity almost to the spinners ; the legs are also less strong 

 and shorter. 



The whole of the fore part, including the legs and palpi, is 

 of a light yellow-brown colour, clothed with greyish-yellow 

 hairs and pubescence, most of which, however, had been 

 rubbed off in the example described : the abdomen is of a 

 uniform pale yellowish buff or dirty cream-white colour, 

 the whole surface as if thickly covered with almost confluent 

 cretaceous spots ; and along the middle of the upperside, in a 

 longitudinal direction, is a very distinct deep-black -brown 

 stripe tapering from the fore extremity to its termination, not 

 far from the hinder extremity, where it appears to dilate a 

 little and to be abruptly truncated. 



The legs are rather shorter and less strong than in M. 

 Thwaitesii, those of the fourth pair, when extended back- 

 wards, reaching but very slightly beyond the extreme hinder 

 point of the abdomen ; the metatarsi of this pair have the 

 calamistrum along their uppersides ; and the correlative infra- 

 mammillary organ likewise exists in front of the six ordinary 

 spinners. 



A single adult female was submitted to me by Mr. H. H. 

 Burton Bradley, of Sydney, New South Wales. It was found 

 in Northern Australia ; but I have no other information re- 

 specting it. 



The occurrence of a species of this curious genus so far 

 from the place where the typical species were not long since 

 discovered (Ceylon) is very interesting, more especially be- 

 cause, as above noted, this is so very closely allied to one of 

 them. 



It is with great pleasure that I have conferred Mr. Bradley's 

 name upon the present species.
