192 LIPURA. 



Post-antennal organ consisting of sixteen elevations in 

 two oblong groups. Hairs few. Skin granular. No 

 hooks at the extremity of the abdomen. 



Length '1 of an inch. 



Common in damp earth throughout the year. 



Sweden, Switzerland, France, England. 



The antennae are shorter than the head ; they are 

 4-jointed and somewhat clubbed. The articulations 

 between the second and third and third and fourth 

 segments are oblique. The organ is covered with 

 short, stiff hairs, which are most numerous on the 

 apical segment. 



The mandibles have four teeth each ; in one of them 

 the penultimate tooth projects beyond the others. 



The body is thinly clothed with short scattered hairs. 

 The legs are short. The principal claw is large and 

 simple ; the smaller one resembles a seta, but is thick- 

 ened at the base. There are no tenent hairs. 



This species has frequently been confounded with 

 L. amhiilans, which, no doubt, it somewhat resembles. 

 They may, however, be at once distinguished by the 

 posterior end of the abdomen, which in L. amhulans is 

 armed with two small upright hooks ; these are en- 

 tirely absent in the present species. There is also a 

 considerable difference in the post-antennal organ. In 

 L. amhulans the elevations are fourteen in number on 

 each side, arranged in two parallel lines running 

 obliquely across the head immediately behind the an- 

 tennaa. L. fimetaria, on the contrary, has, according 

 to Mcolet, only eight on each side, which form an 

 oblong group. They are, however, in botli species very 

 difficult to make out. 



As Nicolet has himself pointed out, his Anuvophorus 

 fimetarius (' Podurelles,' p. 5o) is really the P. amhulans 

 of Linnaeus. 



From L. corticina and L. laricis, which are probably 

 identical, L. fimetaria. is at once distinguished by the 

 colour.
