to indicate that he scarcely looked at the descriptions and figures 

 that he cites. He even refers Dendryphantes meclius C. Koch (see 

 preceding species) and Attus capito Luc. ') to A. litter atus! 



Ohlekt has sent me a $ jun. of Y. v-insignitus under the name 

 of Euophrys striata Obi,. — Concerning the real A. striatus (Clerck), 

 vid. infr. in "Attus striatus Westr." 



The spider, which C. Koch has figured as the female to his 

 Euophrys quinque-partita (Die Arachn., XIV, fig. 1297) bears not the 

 slightest resemblance to the real female of that species, and appears 

 to me to be merely a form of Attus crucigerus Walck. The female 

 of Y. Y-insignitus was in fact unknown to C. Koch. 



Attus Redii Sav. et Aud. 2 ) which Walckenaer 3 ) includes under 

 his Att. qxdnque-partitus , is undoubtedly a totally different species. 



Sch.«ffer's figure in 1c. Ins. Katisb., I, Tab. XXXV, fig. vm 

 {Ar. decern- guttata Panz.), as also Attus Oesneri Sav. et Aud. 4 ), 

 which Walckenaer has taken up under A. litteratus together with the 

 real synonym Ar. V notatus Clerck, are very uncertain identifications. 

 Ar. V notatus is by Sundevall erroneously made synonymous with 

 his A. pubescent (loc. cit. , p. 206). 



A. nidicolens Walck. is a widely different species from Y. v-in- 

 signitus, and is identical with A. phrygianus Sim., Monogr. d. Attides, 

 p. 32 (22). Conf. Sim., Kevis. d. Attidse, p. 141 (17). No one of 

 the species which Walckenaer (H. N. d. Ins. Apt., I, p. 414 and 

 IV, p. 411) refers to his A. nidicolens, appears really to be identical 

 with that spider. 



In Y. y-insignitus the vulva has the form of a small area 

 rounded off in front and at the sides: this area exhibits two furrows 

 diverging backwards, which in the form of a a enclose a reddish 

 brown triangular area. In the only fullgrown female specimen I have 

 seen of Y. festivus (from Silesia, kindly sent me by Dr Zimmermann) 

 the vulva appears to consist of a transversal area rounded before and 

 at the sides, the border of which is elevated all round, but espe- 

 cially behind, where it is slightly emarginated: it is destitute of the 

 A -shaped depression, which distinguishes the vulva in Y. y-insigni- 

 tus. The double V-shaped pale mark in the extreme front of the 

 cephalothorax in this species is also absent in Y. festivus, in the
