 racters of a new Genus. By the Rev. 0. P. Cambridge,

[Plate XIII.] 



The spiders described here are all European, having been sent 

 to me nearly two years ago by Dr. Ludwig Koch, by whom 

 they Avere found near Nuremberg. 



It must be a matter of profound regret to all arachnologists 

 that this able author should be incapacitated (I fear perma- 

 nently) for further arachnological studies by a malady which 

 has seriously affected his sight. 



Family TheridiidsB. 

 AuLETTA, gen. nov. 



This genus is closely allied to Neriene, Bl. ; but the spider 

 on which it is founded can hardly be contained in any of the 

 genera into which the large assemblage of spiders now included 

 in Nericne must inevitably be some day subdivided. 



Cej-jhalotltoi^ax oblong-oval, much longer than broad, very 

 deeply excavated or indented at its posterior extremity ; the 

 lateral marginal constrictions of the caput are gradual. 



Eyes as in Neriene. 



Legs subequal, moderate in length and strength, apparently 

 4, 1, 2, 3, or 1, 4, 2, 3, furnished with hairs and very slender 

 bristles only, each tarsus terminating with three claws. 



Falces rather long, strong, and projecting forwards, armed 

 with a few sharp teeth on their inner sides near the extremity ; 

 fang short and weak. 



MaxillcB tolerably long, subparallel, nearly straight, very 

 sliglitly and obliquely truncated at their extremity on the 

 outer side. 



Lahium somewhat oblong, and half the length of the 

 maxillos. 



Sternnm large, of a somewhat oblong heart-shape, nearly 

 as broad as long. 



Auletta excavata, sp. n. (PL XIII. fig. 1.) 



Adult female, length jy of an incli. 



The whole of the fore part of this spider is of a yellow- 

 brown colour, slightly tinged with reddish. 



The cei)haloihorax is margined by a slender black line, and 

 has a remarkable appearance, owing to the extensive excava- 

 tion of its posterior extremity ; in other respects its form is
