552 MERISTIC VARIATION. [part i. 



Fig. 206, I, shews the normal form of a right maxillary palp. 

 Fig. 206, II, represents the right palp of this specimen. The 1st 

 and 2nd joints are much thickened and the latter has 8 hairs 

 (instead of 4) and two apical articulations, the anterior bearing

an apparently normal terminal joint, the posterior bearing a 

 symmetrical piece ending in a sharp point with no membrane like 

 that at the apex of the normal. The left palp of this specimen is 

 shewn in Fig. 206, III. In it the 2nd joint has 8 hairs instead of 

 4, and the terminal joint though very much enlarged is not 

 divided at all. For the loan of this specimen I am indebted 

 to Dr G. Kraatz who first described it in Bed. ent, Zt, 1873, 

 xvii. p. 4s33,fig. 12.

 mandibles bore an extra process of considerable size. Whether 

 any of these are examples of duplicity, or whether the jaw, mor- 

 phologically single, has in them varied towards a state of greater 

 complexity, cannot well be said. The cases are L. cervus ^ ,
