FIG. 20f>. Nebria gyllenhnlli, No. 8I')0. I. Normal right maxillary palp. 

 II. Right palp of this specimen. III. Left palp of the same, m, terminal 

 membrane. (The property of Dr Kraat/..) 



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 Berl. ent. Zt, 1S~:>.

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