slightly upwards; thence gradually widening towards the top; 

 genu and tibia of uniform shape and almost equal width 

 throughout, only slightly wider in the distal Vs; tibia slightly 

 longer than genu. The whole portion of the leg exteriorly of 

 the femoral constriction is 

 perfectly straight and bent 

 (at the constriction) side- 

 ways and forward at the same 

 angle to the coxa-trochan- 

 terbasifemoral portion as in 

 Änte7inophorus scolopendra- 

 rum Berl. [comp. Berlese 

 2, tab. 66,fig. 8]; tarsus with 

 a feature, very remar- 

 kable in an adult, viz. a 

 distinctly articulatod 

 telotarsus, which attains a 

 length of nearly Vs of the 

 whole tarsus. 



The presence of a dis- 

 tinctly demarcated telotar- 

 sus seems otherwise to be a 

 juvenile character. 



The author has previ- 

 ously recorded it in the 

 nympha of Parasitus fuco- 

 rum (De Geer) [7. p. 386] 

 and Gamasellus (?) brevispi- 

 nosus Tgdh [7. p. 424. fig. 97]

Probably it will, on further Fig^^ 7. Ambulacre of 2nd pair of legs 



researches, be found to be a 

 common nymphal feature, at 

 the Parasitidse. 



As far as I know, it has.. however, not yet been found in 

 adult form s, with the exception of Heterozercon Berl.^ 



^ Berlese [1, p. 207] regards the telotarsus as tarsus. »tarso curtissimo», 

 a view which is not correct, as is evident from a comparison between the 

 nymplia and adult of Parasitus fucorum (De Geer).
