Closely allied, and very similar, to Ero thoracica, C. L. Koch, 

 hut larger, and easily distinguished by having four sub-angular, 

 tubercular, prominences of a larger she on the abdomen ; two 

 of them (the largest) are situated one on each side of its highest 

 part, the other two are placed, one on each side of its posterior 

 declivity, not quite half way to the spinners. 



Found on Bloxworth Heath in September, 1878; and pre- 

 viously received from "Wokingham, where it was found by the 

 Bev. C. W. Penny, of Wellington College. This is its first 

 record as a British spider.
