VAR TRÂGARDH 



Canestrini (1886, p. 709), the second one is longer than the 

 terminal one. 



The second joint widens slightly towards the top, with per- 

 fcctly straight ventral, but slightly convex dorsal, niargin.lt is 

 provided with the usual two dorsal hairs, which are both 

 longer than the joint. Third joint club-shaped, with the usual 

 3 hairs. Fourth joint narrow, cylindrical, nearly five times as 

 long as it is Avide, and provided with about 14 long hairs, placed 

 in the typicaJ way. at IJio top and in tlu-^ dorsal half of tlio 

 joint. 



The maxillae of the same shape as in the main form. 



The organs most modified are the legs, which are — one 

 might well say — enormously developed, the first and second 

 pair being more than twice as long as the body. 



The length of the différent joints of the legs are represented 

 by the folio wing table. 



LENGTH OF BODY 1170 u. 



Thus, legs I and IV are more than twice as long as the body, 

 while in the main form they are of the same length as the 

 body. 



This is, however, not the case in spécimens from ail caves. 

 Thus in a spécimen from n^ 240 the first pair of legs measures 

 2180 p., while the length of the body is the same as in the spéci- 

 men measured above. Consequently, in this spécimen the legs 

 are shorter by nearly one fifth.
