214 REY. O. P. CAMBRIDGE ON [ Mar. 16, 
punctures, and clothed thinly with short hairs ; the sides (below the 
coriaceous epidermis of the upper part) are yellowish, marked with 
indistinct longitudinal bars of a blackish hue ; the spiracular plates, 
and a portion of the surface surrounding the spinners, are of a red- 
brown colour, the rest of the underside being coloured like the 
sides. 
The adult female is rather larger than the male, and wants the 
occipital eminence, the coriaceous epidermis of the abdomen is of a 
similar nature, but does not extend so far backward. The genital 
aperture is, as usual, of characteristic form (see d, fig. 20). 
This species is nearly allied to Erigone nemoralis (BI.) ;. but 
the male may be at once distinguished by the strongly bilobed form 
of the occipital eminence, this peculiarity being scarcely percep- 
tible in that species ; another closely allied species also—L. pavida 
(Cambr.), found in Palestine—may be distinguished by the perfectly 
confluent form of the upperside of the occipital eminence ; and from 
both these species the present one differs in the form of the palpi and 
structure of the palpal organs. 
An adult example of each sex was received from M. Eugéne Simon, 
by whom they were found near Troyes, France. 
ERIGONE CORRUGIS, sp. n. (Plate XXIX. fig. 21.) 
Adult male, length rather under 1 line (about =; of an inch). 
The colour of the cephalothoraz of this Spider is yellow-brown ; 
the thoracic region suffused with dusky blackish, and the lateral 
margins edged with black ; the sternum is rather darker, while the 
falces, maxilee, and labium are similar to the cephalothorax in colour, 
the legs and palpi being pale yellow. The caput has its fore part 
full, bluff, and rounded ; on the upperside towards the occiput is a 
tolerawly strong eminence, of a somewhat bent form (looked at in 
profile), and directed forwards; this is caused by a strong indentation 
or excavation in front at its lower part where the caput proper begins; 
this excavation is a good deal obscured by numercus short bristly 
hairs, which, springing from the fore part of the eminence as well 
as from the caput below, meet across it. A considerable portion 
of the upperside of the fore part of the caput is clothed with short 
hairs, including the two lateral as well as the lower central pair of 
eyes. There are also two longish erect bristly hairs in the median 
line of the upper part of the cephalothorax—one at the base behind 
the occipital eminence, the other at the thoracic junction. 
The eyes are small, in the ordinary position; those of the upper 
pair, separated from each other by no more than an eye’s diameter, 
are placed in front on the upperside of the occipital eminence ; those 
of each of the other three pairs, respectively, are contiguous to each 
other, and placed in a transverse straight line comprising the whole 
width of the fore part of the caput just below the gap between it and 
the occipital eminence ; the eyes, looked at from the front, thus form 
a subtriangular figure, whose base is longer than a perpendicular line 
let fall upon it from the obtuse angle formed by the upper pair of 
eyes; the height of the clypeus exceeds half that of the facial space.
