This beautiful species I have myself met with at Satra in West- 

 manland and at Upsala. A specimen was also sent me by v. Nord- 

 mann from Finnland. 



Nearly related to L. variegata or gracilis Westr. is Bathy* 

 phantes crucifer Menge, which however is immediately recognizable 

 by all its metatarsi being provided with one. spine, whereas in L. 

 variegata they are unarmed: on the posterior metatarsi however may 

 be seen below the middle a fine almost perpendicular hair. The 

 spines on the legs, and the legs themselves, are shorter in L. va- 

 riegata than in Bath, crucifer: on the tibia? of the 1 st pair of legs 

 the spines are in the former species (?) shorter than double the diame- 

 ter of the joint, in the latter species longer than double that diameter, 

 more pointed und tapering. The bristle on the male's patellar joint, 

 which in both species is somewhat longer and coarser than the spi- 

 nes of the legs, is in Bath, crucifer serrulated on the upper margin, 

 in L. variegata fine and smooth. The marking on the upper part of the 

 abdomen in the former moreover does not exhibit the S-formed lines 

 which distinguish my Swedish specimens of the latter species. — 

 Menge obligingly sent me specimens of Bath, crucifer, both cf and 9«

This species, which varies greatly in the colour of the abdo- 

 men, but is easily recognized by the peculiar form of the female's 

 vulva, seems to us to have been with good reason identified by 

 Westring with Lin. dorsalis Reuss, a name which has the right of 

 priority before that given by Blackwall. — Grube's synonym is so
