is certainly identical with Lethia stigmatisata, more recently described by Menge in a 
valuable work on Prussian spiders not yet completed. Examples of Lethia stigmatisata, 
received from Dr. Thorell, are identical with Ciniflo puta. It is not difficult to distin- 
guish it from Ciniflo humilis, Bl. ; but it is more closely allied to the next species here 
recorded. . 
CixirLo Mexe, n. sp. (Pl. XXXIII. no. 7.) 
Male adult, length 1 line. 
A Very similar in form and size to C. humilis (Bl.), this spider may be distinguished 
from it by a darker and more sombre colouring, and especially by the form of the male - 
palpi and palpal organs. 
The cephalothorax is less constricted at the caput, and is of a deep blackish yellow- 
brown colour, marked with darker converging markings, which chiefly follow the direc- 
tions of the normal indentations. 
The legs are moderately long and strong, furnished with dull yellow hairs; some of 
the joints are suffused with brownish yellow; but the legs have no dark annulations as 
in C. humilis. 
The falces are similar to the cephalothorax in colour. 
The maville, labium, and sternum are suffused with yellowish brown of a deeper shade. 
The eyes are smaller and less conspicuous; but those of the fore central pair are pro- 
portionally larger than the corresponding ones in C. humilis, while those of the hind 
central pair are smaller. | 
The palpi are strong, of moderate length, and similar in colour to the legs ; the cubital 
and radial joints are short and strong, the former rather the strongest and longest, and 
without the short pointed spine at the fore extremity on the upperside, characteristic of 
C. humilis; the uppersides of these two joints are furnished pretty thickly with dark 
and, for the most part, curved bristly hairs; the radial joint has a very minute reddish- 
brown pointed spine rather beneath its fore extremity; the digital joint is large and 
pointed, oval in form, longer than the radial and cubital joints together; the palpal 
organs are large, highly developed, and prominent, consisting of a double corneous lobe, 
or one lobe upon another; the upper or outer one has several prominences issuing from 
it, both before and behind, and a filiform spine connected with its superior surface. 
The abdomen is of a deep black-brown colour, with some yellowish markings on the 
upperside forwards, and a longitudinal series of angular lines or chevrons of the same 
colour on the hinder half; the sides are thickly speckled with yellow, and the underside 
is more uniformly suffused with yellow brown. A supernumerary spinner (or pair of 
spinners) is situated in front of the ordinary ones; but the portion of structure (cala- 
mistra) always correlated in the female sex with these supernumerary spinners is wanting 
in the spider now described, and (as far as I am aware)in the adult males of all other 
species possessing them. 
From the adult male of Ciniflo puta (Cambr.),—.Lethia stigmatisata (Menge), this 
species may be distinguished (according to the figures given of the former by Menge) by 
the absence of any spine at the fore extremity of the cubital joints of the palpi, as well as
