224 On a ticw Buprestid from Madagascar. 



in front of the cliclicerje {cf. Jaworowsky, Trochosa) in the 

 case of Ixodes no rudiments whatever of a])penclages are 

 present. If nevertheless we observe the early stages of the 

 development of the appendages, it is not dittieult to discover 

 that between the chelicera? and pedij)alpi there lies yet another 

 pair of tubercles ; consequently there are altogether three 

 pairs of tubercles — a ])airof cheliceriP, a pair of pedi|)alpi, and 

 a pair which is situated between the two former. This latter 

 pair arises later than all the rest of the appendages, and, 

 judging from its position, bears a close relation to the pedi- 

 palpi. This is proved also by sections, since they show that 

 the mesodermal elements of this pair of tubercles form a direct 

 process of the mesoderm of the pedipalpi. In subsequent 

 stages no trace of the tubercles is to be found : I have not 

 yet elucidated their significance.
