401 EEV. 0. p. OAMBEIDGE ON TWO NEW SPIDEES. 



gentleman, in compliment to whom I have bestowed upon it 

 the specific name of Thwaitesii. Subsequently another example 

 (an immature $ ) was received in a second collection, also from 

 Mr. Tliwaites.

Similar to M. Thwaitesii in general form, size, and structure, 

 the present species differs in the form, colours, and markings of 

 the abdomen, as well as slightly in the relative size and position 

 of the eyes, the two middle ones being rather smaller in .propor- 

 tion to the laterals; and slightly wider apart ; i. e. each is nearer 

 to the lateral eye on either side than in M. Thwaitesii ; the line 

 formed by the four eyes is also a little more curved forwards. 



The Abdomen is rather longer and narrower, less generally pro- 

 tuberant above, though rather abruptly elevated near its fore 

 extremity; there are also two short, blunt, somewhat conical 

 eminences (one on either side) about one third of the distance 

 towards the spinners. The whole spider is of a blackish-brown 

 colour, tinged in parts with yellowish, and more or less densely 

 clothed with a short pubescent-like covering of brown, yellowish, 

 white,' and grey hairs, among which are dispersed a few short 

 stumpy spine-like bristles. The tibiae, metatarsi, and tarsi of the 

 1st pair of legs are fringed with long coarse yellowish hairs, like 

 those on the same parts oiM. Thwaitesii; and, also as in that species, 

 the metatarsi of the fourth pair are fringed in a similar manner 

 beneath, and furnished with a calamistrum above. 



The Abdomen has on its upperside three pairs of short, oblique 

 whitish-yellow stripes, formed by cretaceous-looking spots ; these 

 stripes are arranged obliquely, two and two opposite each other, 

 each pair thus forming a sort of broken chevron, with its broken 

 angle directed backwards. The foremost pair of these stripes is 

 situated upon the most elevated part of the abdomen ; the other 

 two pairs occur at similar intervals between the first pair and the 

 hinder extremity of the abdomen ; immediately behind each of 

 those of the first pair is a largish black suftused patch, and 

 each of the other stripes has its hinder margin blackish ; from 

 the fore extremity of each of the middle pair of stripes, a narrow 

 black one runs obliquely across the side of the abdomen to- 

 wards its hinder part. Though very nearly allied to T. Thwaitesii, 

 this species will thus be easily distinguished by the above differ- 

 ential characters.
