Jloricola, has since (Revis. d. Attidse, p. 147 (23)) restored it to its 

 rank as an independent species. A d\ which I received from Dr L. 

 Koch, appears to me to differ from A. Jloricola in having, among 

 other pecularities, the tibial joint of the palpus for the most part 

 covered with dark (black and reddish brown) hair, and only the fe- 

 moral joint towards the apex and the patellar joint above white-haired, 

 as also in having the first pair of legs at the utmost only equal in 

 length to, not longer than, the 4:th: their patella + tibia are only 

 = patella + tibia + half metatarsus of the 4 th pair, whereas in A. 

 jloricola cT the l:st pair's patella + tibia is about as long as the 4:th 

 pair's patella, tibia and whole metatarsus together ')• 



l) I have received from Prof. Wahlgken an Attus found at Eingsjon in 

 Skane , which so closely resembles A. jloricola S , that I can only distinguish it 

 by its having the fore-legs considerably shorter than in the last-mentioned species, 

 scarcely as long as the 4:th pair, and their patella + tibia considerably shorter than 

 the cephalothorax, not, as in A. jloricola 8, of equal length with it. The animal 

 is also smaller than the specimens of A. jloricola $ usually met with, and the 

 process on the tibial joint perhaps a little longer. It is certainly possible that 

 A. jloricola <$ may vary in this manner, and that a sort of dimorphism with 

 respect to the length of the anterior pair of legs may occasionally take place in 

 male spiders, similar to the dimorphism which undoubtedly exists with respect, 

 for example, to the length of the mandibles in certain species, as lAnyphia tri- 

 angularis (Clkrck), Westb. But it is most probable that this short-legged 

 form constitutes an independent species, and it may therefore here be provided 

 with a name and description. 



Attus mancus N. — Mas ad. — Simillimus A. jloricola et vix nisi pe- 

 dibus anterioribus brevioribus distinctus: long, corporis c:a 3 3 /4, cephalothoracis 

 2, pedum l:mi et 4:ti pans 4 millim., patella cum tibia l:mi paris Deque longa ac 4:ti, 

 IV2 millim., ideoque cephalothorace multo brevior; pedes l:mi paris non longiores, 

 potius paullo breviores quam pedes 4:ti paris. Apex lateris exterioris partis tibia- 

 lis palporum in procursuin acutum productus est, qui, quum a latere aspiciatur 

 palpus, paullo longior esse videtur quam ipsa pars tarsalis. 



Cephalothorax niger, linea media tenui albida margineque anguste albido; 

 a linea media, pone oculos posticos, abeunt utrinque linese duae paullo divarican- 

 tes, foras et retro directs?, ex pilis albis et rufescentibus formats. Mox sub ora- 

 lis posticis linea alba sub-sinuata utrinque secundum partem cephalicam sese 

 extendit, quoa lines fere parallels sunt: inter eas et lineam marginalem primum 

 rufescenti-, turn (infra) albicanti-pilosa sunt latera partis cephalicam; area qua- 

 dranguli oculorum rufescenti-pilosa. Linea albida supra et infra oculos medios 

 anticos adest, clypei summus margo quoque albido-pubescens ; oculi illi prseterea 

 annulo angusto pilorum, in lateribus rufescentium , supra et infra albidorum, cir- 

 cumdati. Palpi nigri, supra — lamina nigro-pilosa excepta — albido-pilosi , parte 

 patellari extus rufescenti-pilosa. Pedes nigricantes, maculis ex pilis albis formatis,
