1, p. 512)') is probably quite a different species from Ar. emargi- 

 nata Schranck, as Walckenaer, even in his Ins. Apt., refers it to the 

 genus Thomisns.

 by Guerin-Meneville in his Iconogr. du Regne Anim., Arachn., PI. 



2, fig. 9, under the name of Pldlodromug pallidus Walck., is a spe- 

 cies totally different from Ph. griseus Westr.; it is not an Artanes, 

 as this latter, but probable belongs to the genus Thanatus C. Koch. 



Pag. 269. Philodromus margaritatus Westr. ; p. 476. Ph. pal- 

 lidiis Blackw. — Mr Blackwall, to whom 1 had sent a female spe- 

 cimen of Ph. margaritatus Westr. and another of Ph. griseus id., has 

 confirmed the statement given above (pp. 263, 269), that the former 

 and not the latter species is identical with his Ph. pallidus. 



Pag. 269, 270. Philodromus formicinus Westr. — According 

 to Cambridge 2 ), not only Philodr. Albini Sav. etAuD., but also Tho- 

 misus Fabricii iid., is a different species from Thanatus formicinus; 

 Th. Fabricii ought therefore to be effaced from the synonyms of Ph. 

 formicinus Westr. 



Pag. 273. Lycosa lapponica Thor. — In the description of the 

 female of 7>. lapponica, p. 273, two different species have been con- 

 founded; the female specimen from Finnland, which is there men- 

 tioned, and which is distinguished by the bands on the cephalo- 

 thorax being densely covered with whitish or greyish hair, as also by 

 a grey spear-shaped or lanceolate spot edged with black on the back 

 of the abdomen, in front, and two rows of grey spots behind this, 

 is the true L. lapponica ?, whereas the female specimen from Ka- 

 resuando, referred by me to the same species, and from which the 

 description of the vulva is taken, is a new species, of which I have 

 lately received some specimens from the northwestern parts of Her- 

 jeadalen; it may be called Tj. atrata 3 ). 



1) "TIi. marrjinatus" here is evidently an error of the press for TJi. emar- 

 ginatus. — Th. marginatus Walck. is described in H. N. d. Ins. Apt., I, p. 503. 



2) Gen. list of the Spid. of Palestine and Syria, p. 310. 



3) The two species in question may be distinguished by the following de- 

 scriptions : 



Lycosa lapponica Thor. nigro-fusca, cephalothoracis vittis tribus longitudi- 

 nalibus sub-testaceis, continuis, dense albicanti- vel cinereo-pilosis , media antice 

 abbreviata; pedibus ferrugineis, femoribus supra aut fusco-sub-maculatis, aut ob- 

 scurioribus, macula apicali et basali oblonga clariori, linea nigricanti longitudinali
