il" lit;. <3 is that oï an insect about to moult — the 

 nioult is the September larval moult. (3). The four 

 terminal joints are single, oblong and preceded by 

 I he lemainder ol" the antenna divided into an inner 

 f)ortion and an outer sheatli as far as the base. The 

 outer sheath, formed by the cuticle, contains ^o 

 joints, alternalely light and dark grey (/j); the inner 

 iintcnna has from ■>- to 3o joints of which the most 

 i<M'ent (luv lo successive divisions of the ard joinl 

 are notch(>(i, so Ihal it is very difficidt lo connt them. 

 The first third of llu^ antenna shows dilatations 

 which, though only slight, are sufficient to identify 

 the speciuicn as a male. For it is by the gradual 

 growth of this dilated portion that the striated sheath 

 destined to give rise to the antennal teeth of the 

 adult male is formed. For the time being the most 

 ini[)()rtant fact to be observed is that the inner 

 antenna shows signs of a very rapid formation of nevA' 

 eh'ments in the neighbourhood of the notched por- 

 lion. As this portion corresponds to the third joint 

 of the cast skin, we must (Hniclude that the new 

 i(>ints are formed there.
