102 On the Systematic Arrangement of British Spiders. 



73. Agelena prompta. 



Agelena prompta, Blackw. Linn. Trans, vol. xviii. p. 621. 



Agelena prompta is included by M. Walekenaer among the 

 synonyma of Tegenaria emaciata (Hist. Nat. des Insect. Apt. t. iv. 

 p. 462), from which species it differs in size, organization and 

 colour. It conceals itself under stones in woods about Llanrwst, 

 and the male has the palpal organs completely developed in Oc- 

 tober. 



74. Agelena montana. 



Agelena montana, Blackw. Linn. Trans, vol. xviii. p. 622. 



Hahnia pusilla, Koch, Die Arachn. B. viii. p. 61. t. 270. f. 637, 638. 



Argus montanus, Walck. Hist. Nat. des Insect. Apt. t. iv. p. 505. 



In transferring this spider to the genus Argus, with which it 

 has no relation of affinity, M. Walekenaer has not perceived that 

 it is specifically identical with the Hahnia pusilla of M. Koch. 



Females of this species were discovered in February 1837 

 under stones, on Gallt y Rhyg, a mountain in Denbighshire, near 

 Llanrwst. 



75. Agelena nava. 



Agelena nava, Blackw. Linn. Trans, vol. xviii. p. 623. 

 Argus navus, Walck. Hist. Nat. des Insect. Apt. t. iv. p. 506. 



About midsummer, this species, which, notwithstanding its 

 close connexion with the Agelence, M. Walekenaer has placed in 

 the genus Argus (see the synonyma), may be seen in consider- 

 able numbers running on the ground, and on rails and gates in 

 pastures near Llanrwst. The palpal organs of the male are fully 

 developed in May. 



76. Agelena brunnea. 



Agelena brunnea, Blackw. Lond. and Edinb. Phil. Mag. Third Series, 

 vol. iii. p. 351 ; Research, in Zool. p. 351. 



Agelena brunnea is of rare occurrence in woods in the valley of 

 the Conway. The sexes pair in May, and in the same month the 

 female constructs an elegant vase-shaped cocoon of white silk of 

 a fine compact texture, attached by a short foot-stalk to rushes, 

 the stems of grass, heath, or gorse ; it measures about ^th of an 

 inch in diameter, and contains from 40 to 50 yellowish white 

 spherical eggs enveloped in white silk connected with the inte- 

 rior surface of the c©coon contiguous to the foot-stalk. Greatly 

 to the disadvantage of its appearance, the entire cocoon is smeared 

 with moist soil, which drying serves to protect it from the 

 weather, and, as an additional security, the extremity is closed 

 and directed downwards.
