Metopobactrus prominulus (Camb.) Both sexes; Delamere, 
Wideria fugax (Camb.) Males and females in Delamere 
Forest. The former sex is adult in May. 
Wideria melanocephala (Camb.) One male on July rst; 
Females in June, July, and November. 
Tigellinus furcillatus (Menge). Four males and four 
females of this extraordinary Spider in July. Between Moulds- 
worth and Delamere. It is of great rarity in Britain, but has 
occurred in Dorset, Berkshire, and Yorkshire. 
Gongylidiellum latebricolum (Camb.) Not rare locally in the 
forest. It has previously occurred in Dorset, Northumberland, 
and Scotland. 
Porrhomma miser (Camb.) This Spider may be found 
amongst sphagnum at the Hatchmere end of the forest. 
Tmeticus firmus (Camb.) Mr. FALCONER struck a rich vein 
of this species under a heather bush. This wasinJune. He got 
two males and numerous females. Northumberland and York- 
shire were the only previous records. In the former county I 
could only find males in October and November. That sex has 
not yet occurred in the latter. 
Centromerus empius. sp.nov. Length of male 1°8 mm. (my 
females are rather less). Cephalothorax; legs, palpi, maxille, 
and labium of a yellowish brown colour, the first showing a few 
dusky lines radiating from the thoracic juncture. The abdomen 
is greyish-brown above, shading into dark-brown below. The 
spinners and spiracular plates are of the same colour as the 
cephalothorax and its appendages. 
The cephalothorax is of normal form, sloping up gradually 
from the thoracic juncture to the caput, which is rather prominent. 
The clypeus is distinctly higher than the ocular area. 
ELyes—in two rows as usual, and, of course, eight in number. 
The posterior row is nearly straight; if anything, slightly pro- 
curved. The centrals are the largest of the eight. The posterior 
interspaces are about equal, and each is slightly less than the 
diameter of each posterior central. The anterior row is straight; 
its centrals are the smallest of the eight, and are in contact, or 
almost so. Each is separated from its adjacent lateral by a space 
about equal to its own diameter. The figure formed by the four 
central eyes is much broader behind than before. This descrip- 
tion is from a male specimen. A little variation, both sexual and 
individual, however, may occur. 
The sternum is suffused with dark-brown; it is longer than 
ete and is produced between the coxe of the fourth pair of 
egs.
