The Lycosa, which Fabricius (Syst. Ent., p. 437) calls A. dor- 

 salis, "atra linea dorsali alba", and which has the "abdomen ovatum 

 atrura basi parum albicans" and "pedes lividi", is probably, as also 

 Walckenaer and Sundevall suspected, identical with the spider be- 

 fore us. As however C. Koch and some other naturalists have rec- 

 koned Ar. dorsalis Pabr. among the synonyms of "Lye. montkola, 

 and it certainly is not impossible that Fabricius had before him a male 

 of some species of the Lyc. monticola- group — to which f. inst. Ar. 

 dorsali? Schranck ') evidently belongs — , I have not considered it 

 advisable to accept the specific name dorsalis Fabr. for this species. 

 On the other hand Lyc. (Ar.) lugubris Walck. is undoubtedly the 

 male to Westking's L. siloicola, as C. Koch and Blackwall assume, 

 and as may especially be inferred from the good and comparatively 

 detailed description in Faune Franc., Arachn., p. 24. — L. lugubris 

 Hahn 2 ) on the contrary does not belong to this species, but prob- 

 ably to L. inquilina (Clerck), Westr. ; which see farther on. — L. 

 silvicola Luc. 3 ) is also a totally different spider from that before 

 us. — Walckenaer ') erroneously includes L. silvicidtrix C. Koch and 

 L. alacris id. under his L. vorax. 



In the German male specimens in my collection the upper side 

 of the lamina of the palpus is at the base reddish or yellowish, darker 

 towards the apex; this is rarely the case in the Swedish speci- 

 mens, in which nevertheless a reddish, angularly bent, more or less 

 conspicuous band may be traced across the dark lamina. In a cf of 

 L. lugubris Blackw. from England, sent me by Mr Cambridge, the 

 lamina above is of uniform colour, yellowish brown. — Swedish 

 specimens have been by Dr L. Koch identified with n L. alacris C. 

 Koch". L. silvicultrix C. Koch is evidently the same species as his 

 L. alacris; also in L. silvicultrix the upper part of the lamina is 

 said "to have a shade of red" (Die Arachn., Ill, p. 27). 



At the base, outwards, of the long, pointed, forward di- 

 rected and outward bent spine on the under side of the lamina 

 bulbi, a little tooth is visible. The vulva consists of three trian- 

 gularly disposed, more or less connected and conspicuous fovea?, 

 forming an area rapidly dilating backwards, which at the rima ge- 

 nitalis is bordered by a transversal costa dilated at the extremities
