backwards, and there longitudinally furrowed; on both sides of this 

 septum, near its posterior extremity, is a tubercle. The male's palpi 

 are brownish, with darker lamina; the patellar and tibial joints are 

 white-hairy, as is also the lamina towards the base. The bulbus 

 is at the base swollen into a large knob, the broad and uneven 

 summit of which exhibits a little tooth on the outer side; the ad- 

 joining part of the bulbus, separated from the basal portion hy a 

 depression, is also at its apex produced into a litte point. From the 

 midst of the inner side of the bulbus proceed, outwards, two trans- 

 versal, diverging ridges or elevations, of which the posterior is 

 thinner: viewed from the outer side of the bulbus, it assumes the 

 appearance of a tooth two-pronged or cloven at the extremity. 



In a cf jun. in my collection the whitish grey central line on 

 the fore part of the abdomen is brought to a point backwards, and 

 is bounded by two black borders slightly angularly bent in the 

 middle; the abdomen moreover exhibits two rows of (5—7) small, 

 pale spots: these rows are situated close together and converging 

 backwards, and include between their anterior ends the posterior extre- 

 mity of the central line. — Besides a dried $ and % of this spe- 

 cies, which were lent me by Westking, I have seen a ? ad. and cf 

 jun. found at Valders in Norway and kindly presented to me by 

 Mr Gk Eisen. ■) 



l) I have a $ and J of a spider from Lappland, which both in size and 

 form bears a strong resemblance to L. septentrionalis, but has totally different 

 organs of copulation; for the sake of comparison the following description of it 

 is here inserted. 



Lycosa lapponica N., nigro-fusca, cephalothorace humiliore, vitta media antice 

 abbreviata, ad partem cephalicam tantum pertinenti, vittaque utrinque supra-mar- 

 ginali satis angusta testaceis, albicanti-pilosis ; pedibus ad maximam partem fer- 

 rugineo-fuscis (£) vel luteis ((?), femoribus saltern supra luteo-maculatis ; abdo- 

 mine in (cf saltern) cinereo-piloso, macula antica media sub-lanceolata, nigrore 

 limitata; vulva ex excavatione magna constanti antice et utrinque sub-rectan- 

 gula, postice truncata, septo medio longo, posteriora versus inaequaliter latiore per- 

 secta; bulbo genitali spina longa obliqua, ad basin sub-geniculata , apice paullo 

 recurvo et acuminato, aliaque spina minore transversa ante et sub ilia, denteque 

 in medio marginis exterioris armato. — 3 2 ad. Long. $ c:a 8, $ c:a 7 millim. 



Femina. Cephalothorax forma ut in L. septentrionali fere: 4 millim. longus, 

 parte thoracica paullo depressa; nigro-fuscus, antice pilis longis nigris sparsus, 

 vittis tribus ad longitudinem ductis luteis, quarum media antice ad partem cepha- 

 licam (in quam non continuatur) sub-truncata est, posteriora versus gradatim 

 acuminata, forma fere cunei, sulco ordinario medio fusco geminata; vittae latera- 

 les satis angustae, aut integrse, aut lineis tenuibus transversis fuscis in maculas 

 vel lineolas divisse, ipso margine fusco aeque fere lato atque vitta; vitta? omnes
