803. Meloe violaceus ? : between rigbt eye and tbe base of the right antenna arise 

 two supernumerary antennae /rom the head. Of these one has 3 joints and the other 

 has one. Kraatz, Deut. ent. Zt., 1877, xxi. p. 57, PI. i.fig. 22. 



804, 



The following example is mentioned here, though its nature 

 is quite obscure. In it there is a suggestion that parts of two 

 extra antennae are present, but the extra parts seem to be peri- 

 pheral to the parts which they repeat. 



As my stay in Rouen was short I was not able to give as much 

 time to this specimen as I should have wished 1 . 



Melolontha vulgaris £ : left antenna abnormal. This case 

 differs wholly from any other that I know of. I can only describe 

 it in a most tentative way. The appearance when the lamella 1 

 were cleaned and separated was as shewn in Fig. 179. Joints 

 1 — 8 are fairly normal, but peripheral to this place there were 



Fig. 179. Left antenna of Melolontha vulgaris, No. 804. The numbers are 

 set in tentative suggestion of the possible nature of the parts. (In Rouen Mas.) 



1 This antenna was when I saw it covered with mould and dirt. In washing it 

 I accidentally detached it from the head, but I mounted it again carefully with the 

 specimen.
