Patria incerta: verisimiliter Ro.ssia meridionalis (fortasse Finlandia). Specimcn supra 

 desci-iptum, a Cel. Al. v. Nordmaxx invcntura, benigne mecum communicavit Cel. Prof. 

 M.VKLIN. — Hasc araiiea valde similis est X. luctatori L. KoCH ? sive Thoni. lanioni 

 Westr. ^) et X. bifasciato C. Koch 9, sed notis in diagnosi allatis, prossertim forma 

 vulvie, certe sine negotio dignoscenda. 



^) The Rev. O. P. C.v.mbridge, who has compared the typc-specimen of X. luctator L. Kocil with the types 

 of X. impovidiis TllOR. and Thnm. Voinhriihjii Cambr., has informed me that X. luctator L. Koch is 

 identical with these latter, of whicli Tliom. lanio Westr. is the feuiale. Coi f. TuoU., Kem. on Syn., p. 568.
