The mawxille are rather large, of an elongate-oblong form, 
obliquely truncated on the outer sides at their extremity, and 
inclined towards the labium; they are of a yellow-brown 
colour, tipped with a paler hue, and furnished with coarse hairs, 
some of which (of a papilliform nature) from a kind of tuft 
at their extremities. 
The labiwm is of an oblong form, rounded at its apex, and 
about two thirds as long as the maxiile, to which it is similar 
in colour. . 
The sternum is heart-shaped, furnished with coarse hairs, 
and similar in colour to the cephalothorax. 
The abdomen is oval, and of considerable convexity on the 
upperside ; its colour is yellow-brown with various indistinct 
markings of a paler hue, many of them, however, being fur- 
nished with coarse whitish hairs ; it has thence a more distinctly 
mottled appearance. ‘Two pale longitudinal, rather broken, 
curved and opposed lines occupy the fore part of the upperside, 
and are followed (to the spinners) by several transverse 
angular lines or chevrons, formed of small pale spots, the 
terminal spot on each side being a small patch or blotch; the 
pale spots and markings on the sides assume a rather obliquely 
linear form. In front of the ordinary spinners, which are 
short and of a yellow-brown colour, is the supernumerary 
mamillary organ common to the genus. ‘The genital aperture 
presents the appearance of two roundish reddish-brown open- 
ings rather widely separated in a transverse line, and nearly 
concealed by coarse, dark, bristly hairs. 
Although very nearly allied to Lethia puta (Cambr.), and 
resembling it closely in general colours and appearance, this 
spider is easily distinguished by its much larger size and a 
different form of the genital aperture. 
The specimen from which I have made the above descrip- 
tion was kindly given to me by Mons. Eugene Simon, by 
whom it was found in the summer of 1870, at Newhaven, in 
Sussex. I have retained for this species the nom de cabinet 
under which it was sent to me by M. Simon. 
Lethia albispiraculis, sp.n. (Pl. XE. fig. 1.) 
Adult female, length 1+ line. 
This spider is nearly allied to Z. patula, resembling it 
closely in its general form, hue, and appearance; it is, how- 
ever, smaller; and the three examples examined are all of a 
darker hue and of a more closely freckled look upon the abdo- 
men, upon which also the spots of white hairs are very dis- 
tinct, though liable to be rubbed off, and so to leave only the 
brownish-yellow hue of the markings. A very tangible dis-
