Patria: Hispania (Duf.), Graecia (C, L. Kocii), Rossia meridionalis (Motsch.), /Egyptus 

 (Sav. et AuD.), Algeria (Luc), Ins. Madera (Blackw.), A sia centralis. Multa exempla 

 feininea, ad Atheneon (Sudak) Cherson. Tauricai a Cel. Al. v. Nordmann collecta ante 

 oculos habeo, et prajterea duas feuiinas adultas, in Madera a Cel. Prof. Osw. Heer in- 

 ventas. Nullaui diversitatera in forma corporis inter has feminas omnes et ferainani 

 adultaui "Z. IS-guttati'" (ex Corsica, a Cel. E. Simon missära) invenire possura; nulla in 

 re, nisi pictura abdorainis, ab ea differunt. Mas adultus, is quoque ad Sudak captus, 

 etiam colore abdorainis cura ef " L. 13-guttatr , quera ex Corsica possideo, convenit, 

 neque ullam diversitatera in structura palporura ^) aliarumve corporis partiura ostendit;

In the description of the palpi of L. 13-giittntus o", which I have given iu my Rem. on Syn., p. 513, 

 an error has crept in, which I may be here perraitted to correct. The outer side of the tibial joint is not, 

 as is there stated, drawn out into a loug, downward directed spinc, but (as had been said a few lines be- 

 fore) "into a broad, thin, brown lobe, which seems to be firmly attached to tlie lamina". The inner side 

 of the tibial joint is dilated into a similar but much smaller lobe. 

 ^) The variety of L. 13-guttatus here described seems to be the spider ivhich the Kalmucks of southern 

 Russia call Tschim, and whieli they cousider as extremely venoraous: of the mischief this animal is said to 

 cause among their herds of cattle, we shall speak further on under the head of Trochosa injernalis 

 (Motsch.), which spider Motschoulsky declares to be the Tschim of the Kalmucks. This writer has however ad- 

 duced no proof of this his opinion, which appears to me but littlc probable, since Motschoulsky himself 

 says in the description of his Latrodectiis lugubiis, loc. cit., p. 291 : 



"M. Langenfeld, apothicaire å Sarepta, h robligcance duquel je dois cette espéce, disait qu'on la 

 considére généralement comme étant fort venimeuse et que c'est ä elle qu'on attribue le dégi\t qui est cansé 

 de tems å autre au bétail des hördes nomades des Steppes du Volga, mais je pense qu'il y a une confu- 

 sion d'espéce, quoique fcu Krynicki rapportät aussi que son Latrodectiis 5-Quttatus est, au dire des ha- 

 bitans, venimeux." 



That L. lugubris is the real Tschim, is also made probable by a passage in C. Koch's Die Arachn. 

 (XV, p. 85), where, in a communication from Dr. H. A. Zwick concerning Galeodes araneoides, the following 

 words occur: "I saw in the steppes several camels lie postrate and swelled in consequence of the bites of 

 spiders. This ivas attributed to "the black ividow", Latr. hispidus [= L. lugubris Motsch.]; but Galeodes 

 araneoides might also have had a share in the matter, although I can not give any further reason for this." 



In Pall.\s' Reise durch versch. Prov. d. Russischen Reichs (I, p. 384) a statement is made which verv 

 wcll suits L. lugubris; the Kalmucks of Ural, says he, assure us that, besides the venomous Galeodes
