That Fabricius* "Ar. nigrita, atra; pedes apice pallidi" is iden- 

 tical with the Mehm. pusilla of C. Koch, has been rightly observed, 

 and repeatedly affirmed by that author (Die Arachn., VI, p. 87, 90), 

 and yet he has given it a new name. Such a proceeding of course 

 cannot be approved, and we therefore restore to this spider its oldest 

 specific name, nigrita. 



A cf jun. communicated by Westring, exhibits no sensible dif- 

 ference from a fullgrown £, which I captured at Kissingen in Ba- 

 varia, and which L. Koch has declared to be a M. pusilla C. et L. 

 Koch. The area occupied by the vulva presents, about the middle, 

 two strong, shining, almost j-formed costse curved from each other 

 and rapidly diverging backwards, and behind them another fine trans- 

 versal -^-formed elevation or costa. 



Of the very nearly allied M. violacea L. Koch '), which differs 

 from M. nigrita or pusilla by its more shining cephalothorax , by a 

 somewhat different spine-armature and by its abdomen glittering in 

 green and purple etc. , I have a d" jun. captured at Upsala. It is this 

 specimen that in Rec. crit. Aran., p. 110, 1 have erroneously taken 

 up under the appellation of M. pusilla.
