mimerary spinning organ. The abdomen is thinly clothed with 

 short, strong, hairs. 



This very distinct little spider is allied to Lethia albispiraculis, 

 Camhr., p. 53, but besides being a smaller and more slenderly- 

 made spider, the position of the eyes and the strong spine on the 

 tibia of the third pair of legs, with the two shorter ones on the meta- 

 tarsi of the first pair, render it easily distinguishable. These 

 spines are in fact abnormal to the genus altogether, as at present 

 characterised, but would hardly I conceive render it necessary 

 to exclude it. 



A single example was kindly given to me by Mr. F. M. Camp- 

 bell, of Hoddesdon, where it was found by that gentleman in 

 his dwellinghouse at the end of January, 1880. 



LETHIA PATULA. 



Diotyna patula, Sim., Arachn. de France, torn. 1., p. 197. 



Lethia patoxa, Cambr., Ann. and Mag. N.H. 5 s., vol. 1., p, 

 108. 



Length of the female 2 lines. 



Very nearly allied to Lethia puta, Cambr. (p. 53), resembling it 

 closely in general form, colours, and appearance ; but consider- 

 ably larger. The form also of the genital aperture is quite 

 different. 



Found by Mons. Simon in June and July, 1870, among grass 

 and debris of old furze bushes on the Downs near Newhaven. 

 Sussex.
