This very beautiful species, distinguished by its thick white 

 hairy clothing , is as regards form , scarcely different from /,. taraalU 

 or palustris. As in that species, the metatarsi and tarsi of the 1 st 

 pair in c? are somewhat, if not quite so conspicuously, thickened, 

 with out-standing hairs on the sides; the spine under the bulbus 

 genitalis appears to be still shorter and blunter than in L. palustvi*. 

 The female's vulva has the same form as in that species: its po- 

 sterior angles are strongly rounded off and dilated, and it has, 

 along the middle, a deep, somewhat broad depression, a little broader 

 behind, and also two small fovese in front of the posterior margin. 

 The colour is however quite different: the lateral bands of the cepha- 

 lothorax are very broad, and uneven, almost dentated, on the upper 

 border; the central band is much dilated behind the eyes; more 

 over a little light patch is usually (but not always) met with be- 

 tween the lateral and central bands, behind ; the bands and the patches 

 are thickly clothed with white or greyish white hair. The femoral 

 joint of the male's palpi is clothed with white hair at its extremity, 

 as are also the tibial and tarsal joints above. — English specimens 

 of both sexes of L. herbigrada Blackw. have been kindly sent me 

 by Mr Cambridge. — Blackwall's figure of this species is very bad. 



Another species, also distinguished by a thick white hairy 

 clothing, is L. albata L. Koch (loc. cit.); but in this species the 

 female's white-hairy lateral bands are far narrower, not reaching the 

 edge itself of the cephalothorax, the central band is but slightly di- 

 lated behind the eyes, and the posterior angles of the vulva are 

 pointed; the basal half of the male's lamina bulbi is white-haired, 

 and the tarsi and metatarsi of the 1 st pair are of the ordinary form, 

 not thicker than those of the succeeding pairs. Of L. albata, which 

 has hitherto been found only in the Tatra-mountains and in Buko- 

 wina, Dr Koch has obliged me with a $ and ?.
