dark marks to indicate the usually conspicuous bands — " a little more and 

 they would be absL'iit," he writes to Fitch, " and then, according to • 

 Forster, it would belong to a different sjiecies ! " He thought this species 

 commonest in June. It has several times been bred from the nests of the 

 above spider, Agroeai brunnea, BI., in July, both here and in France. 



Land's End (Marquand) ; common in Norfolk (Bridgman) ; Hastings 

 and Guestling in Sussex (Vict. Hist.); Dorsetshire (Ent. 1881, p. 137); 

 Epping (in Brit. Mus.) ; Whauphill in Wigtonshire, in April (Gordon) ; 

 Isle of ]\Ian (Tomlin) ; Guestling Wood, in moss (Bennett) ; Chiddingfold 

 (Donisthorpe) ; Felden in Herts. (Piffard) ; New Forest and Clacton 

 (W. Ellis) ; Richmond in Yorks. and Oxford, in October (Chitty) ; Oxshott 

 and Boxhill, in May and July (Beaumont) ; both sexes at Shere in Surrey 

 (Capron). The female has occurred to me in tufts of Aira caespitosa at 

 Brede near Hastings, in April, and in the Bentley ^Voods in November, 

 as well as in moss at Foxhall, in March. In August I have taken the male 

 at Lyndhurst, and possess another found by Wilson Saunders at (jreenings 

 in Surrey, in June, 187 1. Miss Chawner lias bred seven females and one 

 male from the nests of the above spider at Burley-in the New Forest, 

 between July and September.

9 . Head finely alutaceous, strongly and closely punctured, dull ; 

 clypeus with deep basal foveae and shallow lateral impressions ; genal 

 sulcus wanting. Antennae moderately long ; first joint of flagellum little, 

 if at all, longer than second, and scarcely longer than the scape ; fifth 

 longer than wide. Thorax finely alutaceous, dull, as closely and distinctly 

 punctured as the head ; meso- and meta-notum equal in length ; petiolar 

 area flat and broadly impressed in the middle ; its basal costa wanting. 

 Abdomen convex, sub opaque, with dense, rather strong puncturation, 

 and moderately close pubescence ; the interstices between the punctures 

 appear smooth, not aciculate, as is usual in this genus ; segment one long 

 and narrow, only slightly widened from middle to apex ; the spiracles vary 

 from almost invisible to moderately prominent ; post-petiole punctate, not 

 transverse ; spiracles on segment two far from the margin ; posterior 

 margins of segments two to six depressed and shining ; terebra not, or very 

 slightly, exserted. 



Head black. Antennae red to middle, thence brownish. Thorax and 

 abdomen red or rufo testaceous ; pubescence fulvous. Legs red ; posterior 

 femora from middle to nearly the apex, and the extreme apex of posterior 

 tibiae, brownish. 



(?. Winged. Metathorax strongly rugulose ; areola and lateral costae 

 indistinct ; petiolar area long. \Vings short ; basal nervure nearly 

 Vertical ; apex of radius a little longer than base ; nervellus greatly ante- 

 furcal. Abdomen broadly fusiform, moderately punctured. 



Head and thorax black. Abdomen rufo-testaceous, with the base and 

 apex black. Coxae black ; femora entirely red, or marked with black ; 

 tibiae red. Length, 3-6 mm. 



\'ery like P. ntjiiisi^ranensis, but the antennae are shorter and the 

 abdomen less strongly punctured and broader. The female differs from
