adduced do not better suit L. frenata than Ar. trilineata. Of the 

 legs Clerck says in his description that they were "a little darkish 

 at the joints." The description of the design of the abdomen agrees 

 far better with Ar. trilineata , even though the lighter ground-colour 

 in Clerck's figure seems more to indicate L. frenata. Neither can 

 I, like Menge, discover, that the expression "buceulentits," full- cheeked, 

 is more applicable to L. frenata Q than to Ar. trilineata. The most 

 important objection to the identity of Ar. buemlentus and Ar. trilineata 

 would seem to be, that, according to Clerck, Ar.bucculentus has the 

 1 st pair of legs longer than the 4 th , which applies to L frenata, but 

 not to Ar. trilineata; it is however also stated that the 4 th pair is 

 longer than the 2 nd , and that suits Ar. trilineata, but not L. frenata! 

 Ar. trilineata Linn, is a spider very common in the neighbourhood 

 of Stockholm and throughout Sweden, whereas L. frenata. is compa- 

 tively rare. Under these circumstances, and as the reasons adduced 

 by Menge do not appear to me sufficiently binding, I have not 

 thought it advisable to abandon the determination of Ar. bucculentus 

 Clerck generally received by Swedish arachnologists. — L. buecu- 

 lenta Walck. (Ins. Apt., II, p. 274) does not belong to this species, but 

 to L. socialis Sund. , as has been observed by Blackwall and Westring.
