Aran, acideatus Clerck and A. nivalis id., the former of which 

 is by Sundevall, the latter by C. Koch identified with the spider 

 before us, are both totally different species: see farther on under Lyc. 

 tceniata Weste. and Lyc. inquilina id. : whereas the spider figured by 

 Ha iin loc. cit. under the name of L. meridiana is undoubtedly, as 

 C. Koch has already remarked, the male of L. nemoralis Westr. 

 Hahn has however, as may be seen from his description of the co- 

 coon, which is stated to be "greenish", confounded with meridiana 

 the female of some other species, probably L. lugubris Walck., with 

 which Hahn's L. meridiana is by Walckenaer identified (Ins. Apt., 

 I, p. 329). The dimensions given by Hahn ("4 lines") are too great, 

 but by comparison with the measure given on p. 18 of "L. cursor", 

 which is a variety of L. tceniata Westr. or Ia nivalis Sund., it is 

 clear, that meridiana" is smaller than that species, to which Sun- 

 devall (loc. cit., p. 184) and Westring (p. 516), though with a note 

 of interrogation, have referred it. The same measure (4 lines) which 

 Hahn gives for L. meridiana, he also gives for e. g. "Lyc. saccata* 

 (amentata) and "/>. piratica". The dimensions that he attributes 

 to the spiders described by him are very often much too great, and 

 in general far from trustworthy. German specimens of T. meri- 

 diana or nemoralis seem however to be really somewhat larger than 

 the Swedish: the cephalothorax in some of the German females in 

 my collection is as much as 4 millim. long, whereas, as Westring 

 correctly states, in the Swedish female specimens it does not usu- 

 ally exceed 2 3 / 4 or 3 millim. — As the figure of Lyc. meridiana 

 given by Hahn appears to me perfectly recognizable, I consider that 

 I am not at liberty to reject the specific name given by him. 



L. borealis Sund., which C. Koch places among the synonyms 

 of this species, is according to Sundevall not a Tarentula, but a ge- 

 nuine Lycosa; see further on under the head of L. borealis. 



By its slender, strongly tapering extremities, L. meridiana forms 

 a link between TarenUda and L.ycosa, but the form of the head 



minatus a latere bulbi interiore exit, magis appressus, foras clirectus, apicem sub 

 basi aculei majoris occultans; ad medium marginis exterioris bulbus dentem acu- 

 minatum nigrum quoque ostendit. 



Exempla duo, alteram masculum, alteram femineum, ad Karesuando Lapponiae 

 Torneensis a Cel. D:re H. Widegren capta, in spiritu vini asservata, possideo; 

 ei Enare Lapponise Fennicae feminam quoque misit Al. v. Nordmann. — Simil- 

 lima est hsec species L. septentrionali, a qua vero forma partium copulationis 

 sine ullo negotio distingui potest.
